# 7 Water Quality Assessment Report: Springs Coast

# Executive Summary

Springs Coast

The Water Quality Assessment Report for the Springs Coast Basin is part of the implementation of the Florida Department of EnvironmentalProtection’s (Department’s) watershed management approach for restoring and protecting water resources and addressing Total Maximum DailyLoad (TMDL) Program requirements. A TMDL represents the maximum amount of a given pollutant that a waterbody can assimilate and still meet the waterbody’s designated uses. A waterbody that does not meet its designated uses is defi ned as impaired. The watershed approach, which is implemented using a cyclical management process, provides a framework for implementing the requirements of the 1972 federal Clean Water Act and the 1999 Florida Watershed Restoration Act (Chapter 99-223, Laws of Florida).A Status Report, published during Phase 1 of the watershed management cycle, provided a Planning List , or preliminary identifi cation, of potentially impaired waterbodies in the Springs Coast Basin. This Assessment Report presents the results of additional data gathered during Phase 2 of the cycle. The report contains a Verifi ed List of impaired waters ( Table 5.3 in Chapter 5) that has been adopted by Secretarial Order and approved by the U.S. Environmental Protection Agency (EPA). TMDLsmust be developed and implemented for these waters, unless the impairment is documented to be a naturally occurring condition that cannot be abated by a TMDL, or unless a management plan already in place is expected to correct the problem. The Verifi ed List also constitutes the Group 5 basin-specifi c 303(d) list of impaired waters, so called because it is required under Section 303(d) of the Clean Water Act. In addition, the report provides the results of a preliminary assessment of ground water quality and ground water to surface water interactions in the basin. It also discusses priorities for further evaluation, resource priorities, and proposed actions. (See Noteworthy in Chapter 1 for a description of the contents of this report, by chapter.) In the Springs Coast Basin, state, federal, regional, and local agencies and organizations are making progress toward identifying problems and improving water quality. Through its watershed management activities, the Department works with these entities to support programs that are improving water quality and restoring and protecting ecological resources. The Department’s TMDL Program objectives will be carried out in the basin through close coordination with key stakeholders and initiatives such as the Southwest Florida Water Management District (SWFWMD); SWFWMD’s Crystal River/Kings Bay Surface Water Improvement and Management Program; Pasco, Hernando, Citrus, and Pinellas Counties; and the municipalities of Port Richey, New Port Richey, Weeki Wachee, Brooksville, Crystal River, Tarpon Springs, Palm Harbor, Dunedin, Clearwater, Largo, and Gulfport.

### Not only do stakeholders in the basin share responsibilities in achieving water quality improvement objectives, they also play a crucial role inproviding the Department with important monitoring data and information on management activities. Signifi cant data providers in the basin include Pinellas County, the SWFWMD, the U.S. Geological Survey, and the Department. During the next few years, considerable data analysis will be done to establish TMDLs for impaired waters in the Springs Coast Basin, establish the initial allocations of pollutant load reductions needed to meet those TMDLs, and produce a Basin Management Action Plan to reduce the amount of pollutants that cause impairments. These activities depend heavily on the active participation of the water management district, local governments, businesses, and other stakeholders. The Department will work with these organizations and individuals to undertake or continue reductions in the discharge of pollutants and achieve the established TMDLs for impaired waterbodies.



## Summary of Surface Water Findings

The Department’s assessment shows that 57 waterbodies or waterbody segments in the Springs Coast Basin are impaired, and 31 of these require the development of TMDLs. The following summarizes, by planning unit, impairments by waterbody types and the primary pollutants. Planning units are smaller areas in the basin that provide a more detailed geographic basis for identifying and assessing water quality improvement activities.

Crystal River/Kings Bay Planning UnitOf the 12 waterbody segments in the Crystal River/Kings Bay Plann ing Unit, 7 segments have suffi cient data for assessment. Of these, 3 are
verifi ed impaired for at least 1 parameter assessed, none remain on the Planning List, and 4 meet standards.
The three verifi ed impaired segments in the planning unit, and the parameters of impairment, are as follows:

Hunters Bay Spring Dissolved oxygen (DO) Tarpon Springs DO
Fort Island Gulf Beach Bacteria

Homosassa River Planning Unit Of the eight waterbody segments in the Homosassa River Planning

U nit, four segments have suffi cient data for assessment. Of these, one is
verifi ed impaired for at least one parameter assessed, one remains on the Planning List, and two meet standards. The verifi ed impaired segment in the planning unit, and the parameter of impairment, is as follows:

As part of the 303(d) assessment of the Springs Coast Basin, the Department received documentation from Pinellas County designed to provide reasonable assurance that proposed pollution control mechanismswould effectively address the nutrient-related impairment of Lake Seminole. While the fi nal agency action on this submittal will not occur until the adoption of the Verifi ed List of impaired waters for the Group 5 basins,the Department has concluded that the Lake Seminole Reasonable Assurance Plan provides reasonable assurance that the lake will be restored. As such, the Department will approve the reasonable assurance proposal as part of the list adoption and will place Lake Seminole in assessment Category 4b (no TMDL required).

Total Maximum Daily Load Priority Areas There are four high-priority areas for TMDL development in the

S prings Coast Basin. Rule 62-303.500, Florida Administrative Code,
defines high-priority waters as waterbody segments where the impairment poses a threat to potable water supplies or human health; waterbody

### segments where the impairment is due to a pollutant regulated by the CleanWater Act and the pollutant has contributed to the decline or extirpation of a federally listed threatened or endangered species, as indicated in the Federal Register listing the species; or waterbody segments verifi ed as impaired that are included on the EPA’s 1998 303(d) list as high priority. The waterbody segments identifi ed as high-priority areas for TMDL development are as follows: Klosterman Bayou Run Tidal (waterbody
identification number [WBID] 1508) for DO, fecal coliforms, and nutrients (chlorophyll a ), on 303(d) list; Stevenson Creek Tidal (WBID 1567) for DO and nutrients (chlorophyll a ); St. Joe Creek (WBID 1668A) for DO and nutrients (historical chlorophyll), on 303(d) list; and Pinellas Park Ditch No. 5 (WBID 1668B) for DO and nutrients (chlorophyll a ), on 303(d) list. All of the remaining parameters causing impairment for the WBIDs placed on the Verifi ed List have been assigned medium priority for TMDL development.



## Summary of Ground Water and Springs Assessment Findings

This section summarizes the results of an assessment of the availability and quality of potable ground water supplies, the impact of ground water on surface water resources, and resource priorities in the Springs Coast Basin. Due to the signifi cant interaction between ground water and surface water via springs in most planning units in the basin, ground water is likely to infl uence surface water quality. The assessment uses planning units consistent with the surface water assessment and water quality data from a combination of databases maintained by the Department and the SWFWMD springs monitoring program.

Basinwide Observations of Elevated Parameter Concentrations Elevated nitrate levels in the basin are well documented by SWFWMD

w ork. These studies have shown that, overall, elevated nitrate levels are present in springs and are attributed to pollutant sources in their springsheds, primarily inorganic sources such as fertilizers. Ammonia (dissolved, measured as N) values from Floridan aquifer system wells and springs are typically very low, except where very localizedsources—such as concentrated animal-feeding operations or malfunctioning septic or sewage systems—are present. Ammonia typically converts to nitrate before it reaches the aquifer. Orthophosphate (dissolved, measured as P) ground water values for
all fi ve planning units are at or near historical background concentrations, except for surfi cial aquifer system values in the Middle Coastal Planning Unit; however, this was based on samples from only two wells. Springs values were also near historical background concentrations, except for amedian value of 0.07 mg/L from two springs in the Anclote River Planning Unit. Observed phosphorus levels in the basin’s surficial and Floridan aquifer wells may, in some cases, be associated with pollutant sources but are probably mainly associated with naturally phosphatic material in 

# 13 Water Quality Assessment Report: Springs Coast

### the aquifers. Because it is the limiting nutrient in many of these systems, however, phosphorus remains a parameter of interest.
DO values from both surfi cial and Floridan aquifer system wells were suboptimal by surface water standards but relatively normal for ground water, with surfi cial values generally higher than Floridan values, as expected, because ground water residence times in the surfi cial are generally
shorter than in the Floridan.

Crystal River/Kings Bay Planning Unit While no surface waters in the planning unit are listed as impaired for

n utrients or DO, there are serious ecological imbalances in Kings Bay andCrystal River associated with nutrients in spring discharges—in particular, the increasing occurrence of the invasive plant species Hydrilla sp. and the alga Lyngbya wollei , and the decline of native submerged aquatic plants. Historical water quality data from Kings Bay springs show that nitrate concentrations in the early 1900s were 20 times lower than they are now. Ground water discharge from area springs is responsible for about 94 percent of the total nitrogen and 84 percent of the total phosphorus entering Kings Bay, and the widespread use of inorganic fertilizers on lawns and golf courses is mainly responsible for the nitrate in ground water. Additional nitrate contributions may accompany future development in the Crystal River area and its springshed. Nitrate-enriched ground water plumes from northern and east-central Citrus County are predicted to reach the Kings Bay Springs Group by about 2010, and there is anomalous high local aquifer recharge in the intensively developed Beverly Hills area, about 8 miles from Kings Bay.

Homosassa River Planning Unit No surface waters in the planning unit are listed as impaired for

n utrients or DO; however, there are ecological imbalances in the Homossassa River (algal blooms and accumulation) caused by nutrients from springs. Nitrate concentrations in the Homossassa Springs Group have increased signifi cantly since the 1970s, and nutrient concentrations in the three springs that supply the Homosassa River indicate that all three likely receive signifi cant recharge from the larger springshed. The principal sources of nitrate in Homosassa and other spring complexes to the south come from fertilizer use in residential areas and golf courses.

Chassahowitzka River Planning Unit No surface waters in the planning unit are currently listed as impaired
fo r nutrients or DO, but similar nutrient-related ecological imbalances are present as in the other Springs Coast spring systems. Nitrate levels have risen twelvefold since the mid-20th century and are over 60 times more than historical statewide background concentrations in the Floridan aquifer. Residential and golf course fertilization are the principal sources of nitrate in Chassahowitzka and other spring complexes to the north and south. Numerous quarries excavated into limestone in the springshed, along with natural karst features in the Brooksville urban area, increase potential recharge directly into the Floridan aquifer. 

# 14 Water Quality Assessment Report: Springs Coast

### Middle Coastal Planning Unit Although no surface waters in the planning unit are currently listed as

i mpaired for nutrients or DO, similar nutrient-related ecological imbalances are present in Weeki Wachee Springs and the Aripeka Springs Group as in the other Springs Coast spring systems—particularly in Weeki Wachee Springs, which has the highest nitrate concentrations in the Springs Coastbasin. The nitrate mainly comes from inorganic sources in the immediate area of the springs, principally residential and golf course fertilizers. The increase in nitrates in Weeki Wachee Springs since the 1940s mirrors the growth in the area’s population and the development of large, coastal residential subdivisions adjacent to Weeki Wachee in Hernando County.

Anclote River/Coastal Pinellas County Planning Unit Unlike the planning units to the north, there are few known springs

i n this unit, and the ones present are of low magnitude—these includeTarpon, Health, and Crystal Beach Submarine Springs. Fourteen waterbodies are listed as impaired for nutrients (chlorophyll a or historical chlorophyll) and 9 are listed as impaired for DO. The largest ground water contribution to these waterbodies likely comes from the surfi cial aquifer via seepage, rather than from the Floridan aquifer via springs. WBIDs 1440A (Spring Bayou Creek) and the adjacent WBID 1508 (Klosterman Bayou Run Tidal) are both listed as impaired for low DO and elevated nutrients. The DO listing is based on high biochemical oxygen demand (BOD). The EPA has published a TMDL for Klosterman Bayou Run Estuary calling for nutrient reductions for total nitrogen and total phosphorus. WBID 1538 (Curlew Creek Estuary) is listed for elevated
fecal coliforms and elevated nutrients.
A number of WBIDs in the western half of the Pinellas Peninsula are listed for high nutrients and low DO: WBID 1567 (Stevenson Creek), WBID 1668A (St. Joe Creek), WBID 1668B (Pinellas Park Ditch No. 5),WBID 1668E (St. Joe Creek Tidal Estuary), and WBID 1709F (Frenchmann’s Creek Basin). Two of these (WBIDs 1668A and 1668B) have TMDLs set by the EPA. All are listed as high- or medium-priority for TMDL development. In each case, total nitrogen and phosphorus are elevated compared with expected values.

# 20 Water Quality Assessment Report: Springs Coast

# Chapter 1: Introduction

Total Maximum Daily Load

The maximum amount of a given pollutant that a waterbody can assimilate and remain healthy, such that all of its designated uses are

met. 

## Purposes and Content of the Assessment Report

The Florida Department of Environmental Protection (Department) is implementing a statewide watershed management approach for restoring and protecting water quality and addressing Total Maximum Daily Load (TMDL) Program requirements. Under Section 303(d) of the 1972 federal Clean Water Act and the 1999 Florida Watershed Restoration Act (FWRA) (Chapter 99-223, Laws of Florida), TMDLs must be developed for allwaters that do not meet their designated uses (such as drinking water, recreation, and shellfi sh harvesting) and are thus defi ned as impaired.TMDLs will be developed, and the corresponding reductions in pollutant loads allocated, as part of the watershed management approach, which rotates through the state’s 52 river basins over a 5-year cycle. Extensive public participation from diverse stakeholders in each of these basins is crucial in all phases of the cycle.A Status Report published during Phase 1 of the watershed management cycle provided a Planning List, or preliminary identifi cation, of potentially impaired waterbodies in the Springs Coast Basin. A copy of the report can be found at http://www.dep.state.fl .us/water/tmdl/stat_rep.htm (under the Group 5 basins). This Assessment Report, which updates the information in the StatusReport, incorporates data collected from the Department’s strategic monitoring and gathered from other agencies and groups during Phase 2 of the watershed cycle. The report contains a Verifi ed List of impaired waters required by the FWRA and Section 303(d) of the federal Clean Water Act, for which TMDLs must be developed and implemented. It also describes the results of a preliminary ground water quality assessment and discusses priorities for further evaluation, as well as resource priorities and proposed actions. (See Noteworthy for a description of the contents of the Assessment Report, by chapter.) Based on the assessment results, 57 waterbodies or waterbody segments in the Springs Coast Basin are verifi ed impaired for 1 or more parameters.TMDLs must be developed for these waters, unless the impairment is documented to be a naturally occurring condition that a TMDL cannot abate, or unless a management plan is already in place to correct the problem. This report is intended for distribution to a broad range of potential stakeholders, including decision makers in federal, state, regional, tribal, and local governments; public and private interests; and citizens.
The Verifi ed List is required by Subsection 403.067(4), FloridaStatutes, and Section 303(d) of the federal Clean Water Act. The Department has adopted the Verifi ed List of impaired waters in accordance 

# 21 Water Quality Assessment Report: Springs Coast

### with the FWRA and Identifi cation of Impaired Surface Waters Rule (Rule 62-303, Florida Administrative Code). The U.S. Environmental Protection Agency (EPA) has also approved this list as the current 303(d) list of impaired waters for the basin, so called because it is required under Section 303(d) of the Clean Water Act.
The fi rst 303(d) list, which was required by the EPA in 1998, is to be amended annually to include basin updates. Florida’s 1998 303(d) list included a number of waterbodies in the Springs Coast Basin. This Assessment Report follows the EPA’s guidance for meshing Clean Water Act requirements for Section 305(b) water quality reports and Section 303(d) lists of impaired waters. The integrated water quality assessment is used to identify the status of data suffi ciency, the potentialfor impairment, and the need for TMDL development for each waterbody or waterbody segment in the basin. Tables 3.5 through 3.9 in Chapter 3 provide an integrated assessment for the Springs Coast Basin, by planning unit. Appendix A describes the legislative and regulatory background forTMDL development and implementation through the watershed management approach, and briefl y explains the TMDL Program. Background information on the Department’s TMDL Program, the process of TMDL development and implementation, lists of impaired and potentially impaired waters, and assessments for other parts of the state is available at http://www.dep.state.fl .us/water/tmdl/index.htm.



## Stakeholder Involvement

The FWRA requires the Department to work closely with stakeholders to develop and implement TMDLs. Stakeholder involvement in the TMDL process will vary with each phase of implementation to achieve different purposes (Table 1.1)

.The Department will work cooperatively with a number of key stakeholders and initiatives to develop, allocate, and implement TMDLs in theSprings Coast Basin. These include the Southwest Florida Water Management District (SWFWMD); SWFWMD’s Crystal River/Kings Bay Surface Water Improvement and Management Program; Pasco, Hernando, Citrus, and Pinellas Counties; and the municipalities of Port Richey, New Port Richey, Weeki Wachee, Brooksville, Crystal River, Tarpon Springs, Palm Harbor, Dunedin, Clearwater, Largo, and Gulfport. 

# 22 Water Quality Assessment Report: Springs CoastWatershed Management Cycle Nature of Stakeholder Involvement

Phase 1: Preliminary
Evaluation Close coordination with local stakeholders to conduct a preliminary basin water quality assessment, inventory existing and proposed management activities, identify management objectives and issues of concern, develop a StrategicMonitoring Plan, and produce a preliminary Status Report that includes a Planning List of potentially impaired waters

Phase 2: Strategic Monitoring
and Assessment Cooperative efforts between the Department and local stakeholders to collect additional data; enter data into STORET (the EPA’s national water quality
STO rage and RET rieval database); complete the water quality assessment; produce a final Assessment Report that includes a Verified List of impaired watersfor Secretarial adoption; and provide an opportunity for stakeholders to document reasonable assurance (for Department review) that existing or proposed management plans and projects are adequate to restore water quality without
the establishment of a TMDL

Phase 3: Development and Adoption of TMDLs Coordination with stakeholders to discuss TMDL model framework, including model requirements, parameters to be modeled, model endpoints, design run scenarios, and preliminary allocations; communication of science used in the process; public workshops for rule adoption of TMDLs

Phase 4: Development of Basin Management Action Plan Broad stakeholder participation in developing a Basin Management Action Plan(B-MAP) (including detailed allocations and implementation strategies), incorporating it into existing management plans where feasible; public meetings during the planning process

Phase 5: Implementation of Basin Management Action Plan Emphasis on implementing the B-MAP, other voluntary stakeholder actions, and local watershed management structures; Department will continue to provide technical assistance, fulfill oversight responsibilities, and administer National Pollutant Discharge Elimination System point and nonpoint source permits Table 1.1: Stakeholder Involvement in the TMDL Program



## The Watershed Management Cycle in the Florida Department of Environmental Protection’s Southwest District

Figure 1.1 shows the order in which the Department’s Southwest District basins will be evaluated under the watershed management cycle. These groups are identifi ed according to a U.S. Geological Survey classification system using hydrologic unit codes. Tampa Bay, a Group 1 basin, was the fi rst basin in the district to undergo a preliminary assessment in 2000. A preliminary assessment for the Group 2 basin, Tampa Bay Tributaries, was completed in 2001. The Group 3 basin, Sarasota Bay–Peace–Myakka, was assessed on a preliminary basis in 2002. Similarly, a preliminary assessment for the Group 4 basin,Withlacoochee, was initiated in 2003, and the Group 5 preliminary assessment for the Springs Coast Basin was begun in 2004. In 2005, the cycle resumed with the Group 1 basin, Tampa Bay.

# Chapter 2: Basin Overview

Basin Setting

The Springs Coast Basin encompasses parts of Pasco, Hernando, Citrus, and Pinellas Counties in west-central Florida. It is bounded on the west by the Gulf of Mexico and on the east by the Brooksville Ridge, a sandy remnant of previous higher sea levels, characterized by porous limestone (karst) geology, with wetlands in low-lying areas and scattered
sinkhole lakes. The basin covers about 1,052 square miles, or 673,000 acres, not including an estuarine ecosystem that extends in a nearly unbroken swathalong the entire shoreline. The estuary’s bays, rivers, salt marshes, seagrass meadows, oyster bars, and tidal fl ats cover approximately another 97,911 acres, or 15 percent of the total basin area. The 6 major rivers in the basin—Crystal, Homosassa, Chassahowitzka, Weeki Wachee, Anclote, and Pithlachascotee—their springs, and their associated coastal aquatic
resources are dominant features. Tidal fl uctuations affect all the springs, except for Weeki Wachee.The coastline along the basin’s western edge is heavily vegetated, shifting from saltmarsh-dominated communities in the northern part of the basin to mangrove-dominated communities in the southern portion. The
low elevation creates fl ooding even during moderate storms. The coast contains numerous tidal creeks and salt marshes, as well as isolated islands fringed with mangroves. There are very few natural sandy beaches. Barrier islands parallel the Gulf coast from southern Pasco County southward to Tampa Bay. A number of passes, or inlets, connect the Gulf
of Mexico with the estuarine waters between the barrier islands and the
mainland. The presettlement vegetation in inland areas of the Springs Coast Basin was dominated by open, fi re-maintained pine forests on sandy uplands and coastal terraces. Longleaf pine was the dominant tree, replaced by slash pine in wetter sites and near the coast, and by pond pine in the wettest inland sites. Wiregrass was the dominant ground cover, particularly in the longleaf pine forests. Other community types, such as sand pine, oak scrub, and mesic hammocks, were embedded in the pine forest. In lower areas, hydric hammocks, swamps, marshes, and other wetland communities predominated. Despite a great deal of growth in the last 30 years, Citrus, Hernando,and Pasco Counties—which are covered by coastal swamps, dense woodlands, lakes, and pastures—have retained a rural character. However, thesethree counties are rapidly changing. Residential and commercial development has rapidly expanded along the narrow U.S. Highway 19 corridor

### that runs between the coastal swamps and the upland forest of the Brooksville Ridge, extending from Crystal River/Homosassa Springs southward to New Port Richey. Pinellas County is mostly developed. Much of the region’s urbanization is relatively recent. Municipalities in the basin include Port Richey, New Port Richey, Weeki Wachee, Brooksville, Crystal River, Tarpon Springs, Palm Harbor, Dunedin, Clearwater, Largo, and Gulfport. The northern portion of the basin, in western Citrus County, contains a number of rapidly growing retirement communities. Dense networks of streets and platted lots are present in the north-central portion of the county. Although relatively few houses have been built, the potential density of these developments at build-out is extremely high. Rapid development is occurring in the U.S. Highway 19 corridor between Crystal River and Homosassa. The extreme western portion of this area is characterized by sparsely populated coastal swamps and wetlands (mostly state or federally owned), and the area between Weeki Wachee and Chassahowitzka remains relatively undeveloped. Much of the upland forest covering the Brooksville Ridge consistsof the Withlacoochee State Forest, which is regularly logged and virtually uninhabited. The forest encompasses approximately 148,000 acres in Citrus, Hernando, Pasco, and Sumter Counties. The largest tract, comprising approximately 43,000 acres, is in central Citrus County; the majority of this tract (approximately 30,000 acres) lies inside the Springs Coast Basin. Northeast of the forest, the city of Inverness, while not in the basin, supports a large residential community, commercial development,
and recreational land uses. The central portion of the basin, in western Hernando County, also contains a number of rapidly growing communities, characterized by moderately dense residential and commercial development. In the vicinity of Spring Hill and Weeki Wachee, residential development occupies a large portion of the area between U.S. Highway 19 and the Brooksville Ridge, particularly between State Road (S.R.) 50 and County Line Road. Spring Hill, with about 60,000 residents, is the largest of the area’s subdivisions. Pasture and forests are prevalent over the central and eastern portions of the central basin. The city of Brooksville, in the east-central portion of the basin, is characterized by residential and commercial land uses. Limestone mining is a major land use northwest of Brooksville. The south-central portion of the basin, in western Pasco County, contains a widespread mixture of residential and commercial development, pasture, forest, and wetlands. The extreme western portion of the basin in Pasco County is characterized by coastal hardwood forests and swamps.The U.S. Highway 19 area, along the Gulf coast, contains densely developed residential and commercial areas. The central and eastern portions of the basin in Pasco County contain pasture, forest, open land, numerous lakes and wetlands, and some scattered row and tree crops. The southern part of the basin encompasses western Pinellas County,from the Anclote River southward to Gulfport and Long Key, and eastward to S.R. 19. (The eastern side of the peninsula lies within the Tampa Bay Basin [a Group 1 basin] and was addressed earlier in the watershed

### management cycle.) Pinellas County, which is already 95 percent built out, has the highest population density in the state and the Southwest Florida Water Management District (SWFWMD). Many of the barrier islandsbordering the Gulf of Mexico are also very densely developed; residential communities in these areas include Indian Shores, Redington Beach, Madeira Beach, Treasure Island, and St. Pete Beach. On the mainland, the largest cities in western Pinellas County areTarpon Springs, Palm Harbor, Dunedin, Clearwater, Largo, and Gulfport. Major waterbodies include the Anclote River, Anclote Anchorage, Intra coastal Waterway, Lake Seminole, Bear Creek, Joe’s Creek, and Long Bayou. The Intracoastal Waterway has different names along its length, including St. Joseph Sound, Clearwater Harbor, the Narrows, and BocaCiega Bay. The Cross Bayou Canal traverses the peninsula in a southwesterly direction from Old Tampa Bay to Cross Bayou, which then fl ows into Boca Ciega Bay. Beginning in the 1920s, numerous waterfront areas in Pinellas County, including Clearwater Harbor and Boca Ciega Bay, were fi lled for residential and commercial development and contain extensive seawalls. From 1950 to 1965, about 20 percent of the surface area of Boca Ciega Bay was fi lled. Most aquatic systems in these areas have deep channels that restrict seagrass growth, and water quality is typically poor. The adjoining areas are also highly urbanized, with Pinellas County having the largest population per acre in the state (SWFWMD, 2001a).Many of the historic freshwater springs have dried up or have been contaminated by saltwater intrusion. Most of the wetlands in the basin are concentrated along the coast and occur in large, contiguous blocks.Of the 194,500 acres in the basin dedicated to conservation, approximately 141,350 acres, or 73 percent, are sandwiched between the Gulf of Mexico and U.S. Highway 19. Three of the 4 large conservation tracts located inland of the coast (Citrus, Serenova, and Starkey) lie on the basinboundary, with large portions extending into adjoining basins. Conservation lands in the basin include 130,250 acres of state-owned lands, 18,500 acres of SWFWMD-owned lands, 3,500 acres of county-owned lands, and nearly 1,000 acres of privately owned lands. The Chassahowitzka National Wildlife Refuge, established in 1931, comprises 31,000 acres of shallow saltwater bays, estuaries, brackish marshes, and tidal streams, with a fringe of hardwood swamps. Accessible only by boat, the refuge provides habitat for approximately 250 species ofbirds, over 50 species of reptiles and amphibians, and at least 25 different species of mammals. Endangered and threatened species found in the refuge include manatees, sea turtles, and bald eagles. The Crystal River National Wildlife Refuge, established in 1983 and located in Citrus County, comprises 20 islands and several small parcels of land, surrounded by the crystal-clear, spring-fed waters of Kings Bay. Six hundred million gallons of fresh water fl ow daily from more than 30 natural springs in the refuge. The water fl owing from the springs remains at a constant 72°F. The springs are Florida’s most signifi cant natural warmwater refuge for the endangered West Indian manatee and provide critical habitat for the Crystal River herd, which makes up about 

# 29 Water Quality Assessment Report: Springs Coast

### 25 percent of the country’s manatee population. They also provide habitat and protection for numerous other wildlife species. Anclote Key, the northernmost barrier island in the basin, comprises the Anclote Key Preserve State Park. The island is still expanding and has increased in size by about 30 percent since 1957. Just to the east of Anclote Key lies Anclote Anchorage, a shallow area containing seagrass beds that provides breeding habitat for numerous marine species, including threatened and endangered animals such as sea turtles and the West Indian manatee. The Anclote National Wildlife Refuge encompasses the waters between Anclote Key and the mainland. South of Anclote Anchorage is the Pinellas County Aquatic Preserve. The waters near the preserve attract numerous sponge divers. Honeymoon Island State Park, Honeymoon Island State Recreation Area, and Caladesi Island State Park, which are undeveloped, are located along the Gulf coast in northern Pinellas/southern Pasco Counties. A 1921 hurricane split Honeymoon Island in two, creating Hurricane Pass and Caladesi Island to the south. Honeymoon Island contains one of the few remaining south Florida stands of virgin slash pine, which provides osprey nesting sites. Both Honeymoon Island and Caladesi Island contain a number of important coastal plant communities such as mangrove swamps, seagrass beds, salt marshes, tidal fl ats, and sand dunes. Honeymoon Island has more than 208 plant species and a variety of shorebirds, including several threatened and endangered species. To the east of Honeymoon and Caladesi Islands lies St. Joseph Sound. It contains about 14,700 acres of seagrass, which is about 60 percent of the total seagrass acreage found in Tampa Bay. Other major, publicly owned conservation areas in the basin include the following:

• The Chassahowitzka River and Coastal Swamps Area, comprising

5,676 acres in western Citrus and Hernando Counties, contains the
headwaters of the Chassahowitzka River and several tributaries and springs;
• Starkey Wilderness Park, an 8,069-acre tract, encompasses a portion

of the headwaters of the Anclote River and a stretch of the Pithlachascotee River; and

• Weeki Wachee Preserve, a 9,000-acre area, is located on the Gulf

coast in Hernando County. It contains the southernmost coastal
hardwood hammock in western Florida. Limerock was mined in the southwest corner of the preserve from the 1940s through 1995.

The Crystal, Homosassa, Chassahowitzka, Weeki Wachee, Anclote, and Pithlachascotee Rivers and their associated coastal aquatic resources are popular for recreational activities such as swimming, scuba diving, snorkeling, fi shing, and boating. The U.S. Fish and Wildlife Service estimates that there were 91,515 visitors to the Crystal River National Wildlife Refuge and 33,340 visitors to the Chassahowitzka National Wildlife Refuge during 1996. Estimated visitors in 1997 at other nearby 

# 30 Water Quality Assessment Report: Springs Coast

### sites include 250,000 at Homosassa Springs State Wildlife Park, 17,800 at the Chassahowitzka River Campground and Park, and 70,000 at the park
at Pine Island. In 1979, recreational fi shing trips and total number of fi sh landed on Florida’s west coast, including the Springs Coast Basin, exceeded that
of Florida’s east coast and all other shorelines in the southeastern United States. The counties of the Springs Coast Basin, collectively, generated 18,370 fi shing trips and landed over 4.5 million pounds of seafood in 1995. By 1999, the number of fishing trips had grown to 19,753, with approximately 5.1 million pounds of seafood landed. Agriculture was the historical economic base in Citrus, Hernando, and Pasco Counties. Several factors, however, including residential growth, the decreasing profi tability of farming, and freezes affecting the citrus industry, have had a dramatic effect. Today, these counties’ economiespredominantly comprise retail trade, services, government, and construction. A signifi cant portion of Hernando County’s economy is still based on industry (including mining), cattle, and agriculture. Signifi cant limerock mining activities are carried out northwest of Brooksville. Western Pinellas County is largely urban, with some industrial development.
Table 2.1 lists the acreage and percentage of total acreage for land usesand land cover in the Springs Coast Basin. The table shows that over onethird of the basin (34 percent) is urban and built-up, followed by upland forests (26 percent) and wetlands (22.1 percent).

### Table 2.2 lists historical and projected population fi gures for the basin. In 1980, the population of the four counties (Citrus, Hernando, Pasco, and Pinellas) was almost 1.02 million. By 1998, it had risen to more than 1.45 million, and by 2020 is projected to grow to more than 1.8 million. There is also a large infl ux of seasonal residents into the basin during the winter
months.U.S. Highway 19 and U.S. Highway 41 are the major north-south corridors through Citrus, Hernando, Pasco, and Pinellas Counties. Continued 

# 31 Water Quality Assessment Report: Springs Coast

### population growth in the basin was fueled by the construction of the Suncoast Parkway (S.R. 589) during the 1990s. The 42-mile parkway, which extends from the Veterans Expressway in Tampa to U.S. Highway 98 near the Hernando–Citrus County line, connects Hillsborough County with Pasco and Hernando Counties and provides an alternate north-south route through Florida’s west coast. In Pinellas County, S.R. 699 runs north- south through the barrier islands from Largo to St. Pete Beach. Major east-west highways in the basin include S.R. 44, which connectsthe coastal areas around Crystal River with Inverness; S.R. 50, which originates in western Hernando County near Weeki Wachee and passes through Brooksville; and S.R. 52, which originates in western Pasco County. Numerous other roads and highways crisscross the western Pinellas peninsula. Regional airports include the Crystal River and Hernando County Airports.

Coast Basin. Appendix B contains supplementary information on the basin’s ecology.



## Surface Water Resources

The Springs Coast Basin contains numerous surface waterbodies. Surface waters, including lakes, streams, wetlands, and springs, occupy 259 square miles, or about 24 percent of the total basin area. This section delineates the basin’s hydrology, describes the movement and management of water in the basin, briefl y describes the major characteristics of surface
waters that infl uence water quality in the basin, and describes surface water

Physiography and Hydrology There are three physiographic regions in the Springs Coast Basin,
ba sed on topographic relief and underlying sediments: the Coastal Swamp, Brooksville Ridge, and Gulf Coastal Lowlands. While it does not lie within the Springs Coast Basin, a fourth physiographic region, the Tsala Apopka Plain, also plays an important role in the basin’s water resources. The Coastal Swamp region parallels the coast, extending 2 to 5 miles inland. It is characterized by tidal marshes and coastal swamps. Elevations are less than 10 feet, and poorly drained, organic soils directly overlie the limestones of the Floridan aquifer system in much of the area. The Brooksville Ridge, in the central portion of the basin, trends northwest-southeast through central Citrus County and eastern Hernando and Pasco Counties. The ridge measures approximately 17 miles wide incentral Hernando County and reaches its southern terminus in northeastern Pasco County. Elevations range from 70 to about 275 feet. The ridge has an irregular surface due to karst activity, and elevations may vary morethan 100 feet over short distances. The margins of the ridge are characterized by deep sandy soils, while the interior contains a mixture of poorly to well-drained sandy-clayey soils. The entire Brooksville Ridge region is underlain by a clayey unit that varies between 10 and 30 feet in thickness, but allows good hydraulic connection to the underlying Floridan aquifer system through karst features and fractures. The ridge supports upland communities such as longleaf pine sandhills, sand pine, and oak scrub, as well as numerous threatened and endangered species. The Gulf Coastal Lowlands consists of a poorly drained, triangular area in the southern portion of the basin that lies between the Coastal Swamp region and the cliffs of the Pamlico Scarp on the west, and theBrooksville Ridge on the east. It varies from 2 to 8 miles wide, and elevations range from sea level to about 100 feet. The topography consists of relatively fl at coastal swamps, river valley lowlands, and rolling hills made up of eolian, or wind-sculpted, sand dunes. Soils comprise sands or clayey sands. The Tsala Apopka Plain lies between the Brooksville Ridge and the Withlacoochee River within the recharge area of the coastal springs. Itcontains a large number of interconnected lakes that are divided by peninsulas and islands; these lakes are remnants of a much larger lake that once covered the entire Tsala Apopka Plain. Siliciclastic deposits cover the limestone surface, and elevations range from 35 to 75 feet. The soils are generally sandy and weakly cemented with organic matter.

Streams In the northern part of the basin, the principal waterbodies are the

c oastal, spring-fed Crystal, Homosassa, Chassahowitzka, and Weeki Wachee Rivers. All 4 rivers originate from fi rst-magnitude springs near the coast, meaning that each spring discharges an average of 100 cubic feet 

# 34 Water Quality Assessment Report: Springs Coast

### Figure 2.2: Surface Water Resources of the Springs Coast Basin 

# 35 Water Quality Assessment Report: Springs Coast

### per second (cfs) or more. These rivers are typically less than 10 miles in length. As a result, only a limited amount of runoff is channeled from the upper basin to the rivers. Hammock Creek, at Aripeka, is a coastal system formed by several lesser-magnitude springs and swamp discharge. In the southern portion of the basin, surface water drains either directly to the Gulf of Mexico or to the Pithlachascotee (Cotee) or
Anclote Rivers. The lack of rivers and streams in the interior of the Springs Coast Basin results from a well-developed underground drainage system in the underlying limestone. Most of the area has a well-developed karst topography, with hundreds of shallow depressions, sinkholes, circularlakes and ponds, and active springs. Precipitation falling on the Brooksville Ridge rapidly moves underground through numerous sinkholes and
fissures, and begins moving toward the Gulf of Mexico through an extensive system of conduits.Crystal River and Kings Bay are located in Citrus County approximately 60 miles north of Tampa. The tidally infl uenced Kings Bay is the headwater of the Crystal River, which forms at the northwest corner of the bay. Six miles west of Kings Bay, the river ends at the Gulf of Mexico. The Crystal River/Kings Bay system, the fourth largest of the 33 fi rst- magnitude springs in Florida, contains a cluster of at least 30 springs. While other spring systems in the state are also tidally infl uenced, the presence of the 600-acre Kings Bay embayment makes this hydrologic system unique. Like Crystal River, the Homosassa River is a coastal, spring-fed river and estuarine system located in west Citrus County. The river extends approximately six miles from its headwaters at Homosassa Springs to the Gulf of Mexico. The Homosassa’s major tributary is Halls River. The Chassahowitzka River is located in southwestern Citrus County approximately six and one half miles south of Homosassa and just north of the Citrus/Hernando County line. The river is fed by numerous springs
and fl uctuates seasonally with ground water levels. Crab Creek, Cabbage Creek, Baird Creek, Salt Creek, Potter Creek, Crawford Creek, Blue Run, Ryle Creek, and May Creek all fl ow directly to the Chassahowitzka River,
while Chub Creek and Blind Creek fl ow to the Gulf of Mexico. The Weeki Wachee River is located in southwest Hernando County, approximately 12 miles southwest of the city of Brooksville. Weeki Wachee Springs is the headwaters of the river and the largest of 9 springs associatedwith the Weeki Wachee system. The springs were developed as a commercial attraction featuring “live mermaids.” The Weeki Wachee Riverextends westward through approximately 7.5 miles of predominantly lowlands (coastal swamps and marshes) to the Gulf of Mexico. Its 2 principal tributaries are the Mud River and Jenkins Creek.The Hammock Creek system includes several small springs clustered in a one-square-mile area in southwestern Hernando County, near Aripeka. Hammock Creek, approximately one mile in length, is joined by several lesser tidal creeks before reaching the Gulf of Mexico at the town of Aripeka. The springs either discharge directly into Hammock Creek or 

# 36 Water Quality Assessment Report: Springs Coast

### discharge into the lesser creeks fl owing into Hammock Creek. The creek’s water is brackish nearly to the headsprings. The Pithlachascotee River starts in Hernando County as channeled
fl ow through the Masaryktown Canal. It then flows southwest to its headwaters, Crews Lake, through an area of interconnected lakes and sinkholes in south-central Hernando County, near Brooksville. From there, it fl ows about 25 miles through a poorly defi ned channel to the Gulf of Mexico at Port Richey. The river includes both estuarine and freshwater reaches. As
it fl ows, substantial amounts of water drain underground to the Floridan aquifer. The river has very low base fl ow. During low-fl ow conditions, most of its water comes from ground water seepage. During high-fl ow conditions, surface water runoff constitutes most of the fl ow. The Pithlachascotee watershed contains numerous water table marshes and lakes, including Crews Lake. These fl uctuate with ground water levels and may disappear completely during dry spells or with heavy ground water pumping. The Anclote River originates in swampy lowlands in south-central Pasco County, east of New Port Richey, and from there meanders in a southwesterly direction, entering the Gulf of Mexico just north of Tarpon Springs. The lower reach of the Anclote River is a tidal estuary that fl ows into Anclote Anchorage, a shallow area of seagrass beds to the east of Anclote Key. Tidal infl uences extend as much as 14 miles up the river. The mean depth of the lower river is just over 3 feet, except for a dredged shipping channel about 15 feet deep that extends from Tarpon Springs to the river mouth. Salinity at the river mouth ranges from 0.8 to 32.7 parts per thousand, depending on rainfall and tidal fl ows.

Springs The Springs Coast Basin contains 4 major spring complexes, which

oc cur because of the region’s karst geology. A spring complex is a group of springs, often spread out over several square miles, that are discharge points for ground water in a discrete ground water basin. Combined, these 4 complexes discharge approximately 900 million gallons per day (mgd) from the Floridan aquifer system. Rainfall, which is the primary recharge mechanism for the aquifer, averages 56 inches per year. Spring fl ow is a major discharge mechanism for the aquifer, accounting for 64 to 84 percent of the total recharge input. The Crystal River/Kings Bay Springs Complex, the largest such complex in the basin, discharges approximately 630 mgd. The three other major springs—Weeki Wachee,Chassahowitzka, and Homosassa—discharge 113, 90, and 68 mgd, respectively. Other large springs in the basin include Ruth Spring, Salt Spring, Little Springs, Bobhill Springs, Magnolia Springs, Horseshoe Spring, Salt Springs, Wall Springs, Crystal Beach Springs (which is located about 1,000 feet offshore), and Tarpon Springs (which is tidally infl uenced and
can reverse fl ow). 

# 37 Water Quality Assessment Report: Springs Coast

### Lakes Including Crews Lake, which covers approximately 693 acres, there

a re approximately 137 lakes in the Springs Coast Basin, with a surface area totaling approximately 1,503 acres. Of this acreage, 555 acres are made up of lakes smaller than 10 acres. In addition to Crews Lake, other large lakes in the basin include Hunters Lake, Weeki Wachee Prairie Lake, Hog Pond, Grear Hope Pond, Tooke Lake, and Lake Seminole.Most of the basin’s lakes, springs, and ponds occur in shallow depressions on the land surface. Their surface area varies considerably with seasonal changes in rainfall: they cover large areas during the wet season and, in some cases, dry up completely during the dry season or in times of drought. Many of these wetland areas are marshes rather than lakes. The marshes are hydraulically connected to the water table aquifer, and the
fl uctuations in surface water elevation are directly related to changes in the
water table. Several lakes in the basin are directly connected to the underlying Floridan aquifer by sinkholes in the lake bottoms. Crews Lake, the largest of these waterbodies, has a sinkhole located in the north part of the lake. The lake level has varied seasonally at least since the mid-1800s. During very dry years, the lake has been completely drained through the sinkhole. Lake Seminole, which covers 980 acres and averages about 5 feet in depth, was formerly the upper reach of Long Bayou. In 1950, a dam was built across the bayou severing the hydraulic connection and eliminating
tidal fl ushing. Until 1967, Lake Tarpon, the largest lake in the county at 2,534 acres, was connected hydrologically to Spring Bayou, which fl owed into the Anclote River. However, the U.S. Army Corps of Engineers dammed the lake to control saltwater intrusion. The lake now discharges through an
artifi cial control structure into Tampa Bay near the city of Safety Harbor.

Nearshore EstuaryThe northern portion of the Springs Coast Basin has no classic estuari es, where brackish waters are separated from the ocean by physical barriers such as islands. In many ways, however, this coastal area functions like an estuary, with its shallow waters, abundant freshwater fl ows, and low-energy shoreline. Seagrass beds cover almost the entire nearshore area along the northern portion of the basin, and extensive oyster reefs are also present. From the Anclote River southward to the mouth of Tampa Bay, a 45-mile-long chain of barrier islands parallels the coast, creating sheltered, open saltwater areas and associated shallow-water features such as salt marshes, beaches, seagrass meadows, and tidal flats. Historically, drainage to these estuarine areas came mainly from sheet fl ow across the land surface, bayous, and small tidal creeks. This stretch of coastline, however, is now intensively developed and receives large amounts of drainage from urban stormwater systems. In the Springs Coast Basin, the nearshore estuarine area covers about 996 acres. Although this region is a defi ning surface water feature in the basin, its significance far exceeds its areal extent. It provides essential habitat for numerous fi sh and wildlife species, including nursery and juvenile 

# 38 Water Quality Assessment Report: Springs Coast

### habitats for many recreational and commercial fi sh species. The economic
value of commercial seafood harvests on Florida’s west coast consists of at least 95 percent estuary-dependent species. The estuary’s wetland vegetation helps to maintain or improve water quality by fi ltering and assimilating many waterborne pollutants and stabilizing bottom sediments. It also provides a buffer between developed shorelines and the open waters of the Gulf of Mexico that can absorb some of the destructive impact of storm-generated winds and tidal surges. A long band of hydric hammock forest occurring just inland of the estuary provides additional protection to much of the shoreline of Hernando and
Citrus Counties.

Surface Water Quality ClassificationsFlorida’s water quality standards, the foundation of the state’s prog ram of water quality management, designate the “present and future most
benefi cial uses” of the waters of the state (Subsection 403.061[10], Florida Statutes [F.S.]). Water quality criteria for surface water and ground water, expressed as numeric or narrative limits for specifi c parameters, describe the water quality necessary to maintain these uses. Florida’s surface water is
classifi ed using the following fi ve designated use categories:

Class I Potable water supplies Class II Shellfi sh propagation or harvesting Class III Recreation, propagation, and maintenance of a healthy, well-balanced population of fi sh and wildlife Class IV Agricultural water supplies Class V Navigation, utility, and industrial use (there are no state waters currently in this class)

All of the waters in the Springs Coast Basin are Class III, marine or fresh waters, except for a portion of Crystal River (waterbody identifi cation number 1341), which is a Class II water.

Special Designations

Outstanding Florida Waters 

### The following waterbodies in the basin have been given additional protection through designation as Outstanding Florida Waters (OFWs): Crystal River and Kings Bay, Chassahowitzka River, Crab Creek, Cabbage Creek, Baird Creek, Salt Creek, Potter Creek, Crawford Creek, Blue Run, Ryle Creek, May Creek, Chub Creek, Blind Creek, and Weeki Wachee River. In addition, all of the lakes and streams in Pinellas County

are OFWs. OFWs are designated for “special protection because of their natural attributes” (Section 403.061[27], F.S.). These waters are listed in Section 62-302.700, Florida Administrative Code (F.A.C.). The intent of an OFW designation is to maintain ambient water quality, even if these designations are more protective than those required under the waterbody’s surface water
classifi cation. Most OFWs are associated with managed areas in the state 

# 39 Water Quality Assessment Report: Springs Coast

### or federal park system, such as aquatic preserves, national seashores, or wildlife refuges. Other OFWs may also be designated as “Special Waters”
based on a finding that the waters are of exceptional recreational or ecological signifi cance, and are identifi ed as such in Rule 62-302, F.A.C.

Surface Water Improvement and Management Priority Waters 

### Crystal River/Kings Bay has been designated as a Surface WaterImprovement and Management (SWIM) priority waterbody for restoration. The original SWIM plan for the river and bay was prepared and approved in 1989, and the plan was updated in 2000. In 1987, the Florida legislature created the SWIM Program to restore waterbodies. The initial legislation identifi ed 6 priority waterbodies: Lake Apopka, Tampa Bay, Indian River Lagoon, Biscayne Bay, Lower St. Johns River, and Lake Okeechobee. Today, SWIM plans have been developed for 30 waterbodies statewide. The SWIM Program addresses a waterbody’s needs as a system of connected resources, rather than isolated wetlands or waterbodies. The state’s 5 water management districts work with federal,state, and local governments and the private sector to develop and implement SWIM plans to restore damaged ecosystems, prevent pollution from runoff and other sources, and educate the public.

Minimum Flows and Levels 

### Table 2.3 lists the 1999 priority schedule for minimum fl ows and levels (MFLs) in the Springs Coast Basin. Of particular concern is the impact of ground water development on coastal spring discharges and
freshwater flows to the coastal estuaries. The Springs Coast Basin is internally drained, and the upper Floridan aquifer is the primary source of water to its numerous coastal springs, which in turn are the principal source of

### surface fl ow in the coastal rivers area. Approximately 1.3 billion gallons of water are discharged from the coastal springs daily. Under the Florida Watershed Restoration Act (FWRA) (Chapter 373, F.S.), MFLs are the limit at which further water withdrawals will cause signifi cant harm to the water resources of the area and related natural systems. Consumptive use and alterations to their watersheds have reduced, or have the potential to reduce, the amount and timing of surface water being delivered. Projected increases in withdrawals also could reduce future
fl ows and levels.To help determine the amount of water that is available for environmental and human uses, the SWFWMD must determine MFLs. Lakes and aquifers have minimum levels. Minimum fl ows are set for rivers and

streams.



## Ground Water Resources

Aquifers

Geology 

### The geology of the Springs Coast Basin is relatively simple, with thicksequences of limestone exposed at or very near (10 to 20 feet) the land surface in the eastern and western portions of the basin. Where the limestone is near the land surface, the thin veneer of sediment covering the limestone consists of unconsolidated deposits of primarily quartz sand. These sands are marine terrace deposits and coastal dune trains. Dunes are prevalent in the Coastal Lowlands and along the fl anks of the Brooksville Ridge. The limestone units include the Suwannee Limestone of Oligocene ageand the Ocala Limestone of Eocene age. Underlying these exposed limestone units is the Avon Park Formation of Eocene age. The Avon Park Formation is the deepest formation containing potable water. The Suwannee and Ocala Limestones and the Avon Park Formation comprise the Floridan aquifer system in the basin.In the Brooksville Ridge area, undifferentiated quartz sand and sediments of the Hawthorn Group overlie the Floridan aquifer system. The Hawthorn Group sediments were deposited in a variety of environments and consist of sand, silty sand, and waxy green clay. Phosphorite pebblesand fossil oyster bars are common. Between Brooksville and the Hernando–Citrus County line to the north, the Hawthorn sediments have largely been eroded off the Brooksville Ridge, and the limestone is exposed or near the land surface in many of the high areas. Karst processes play a dominant role in moving ground water through the Floridan aquifer system in the basin. The four physiographic regions (the Coastal Swamp, Gulf Coastal Lowlands, Brooksville Ridge, and TsalaApopka Plain) in or adjoining the spring recharge zone are areas of intensive karst development characterized by numerous sinkholes, a lack of surface drainage, and undulating topography. In karst areas, the dissolution of limestone creates and enlarges cavities along fractures in the limestone that eventually collapse and form sinkholes. Sinkholes capture surface water drainage and funnel it underground, which promotes further dissolution 

# 41 Water Quality Assessment Report: Springs Coast

### of the limestone. This leads to the progressive integration of voids beneath the surface and allows larger and larger amounts of water to be funneled into the underground drainage system.
Dissolution is most active at the water table or in the zone of water
table fluctuation, where carbonic acid contained in atmospheric precipitation and generated by reaction with carbon dioxide in the soil reacts with
limestone and dolostone. Because the elevation of the water table shifted inresponse to changes in sea level, many vertical and lateral paths have developed in the underlying carbonate strata in the basin. Many of these paths or conduits lie below the present water table and greatly facilitate ground
water fl ow.

Surficial Aquifer System 

### The surfi cial aquifer system in the basin consists of quartz sand, silty sand, and clay. The surfi cial aquifer is most likely to occur as a distinct hydrostratigraphic unit along the Brooksville Ridge, where the low- permeability clays of the Hawthorn Group retard the downward movement of water into the Floridan aquifer system. The collapse of the underlying limestone, however, has produced numerous breaches in the clays that act
as vertical conduits for the movement of water from the surfi cial to the Floridan aquifer system. The Hawthorn sediments are also not widespread between Brooksville and the Hernando–Citrus County line. In areas where saturated sand lies directly above the limestone, water in the sand is hydraulically connected to the Floridan aquifer. Since the majority of the basin has no extensive confi ning layer, most of the region
does not have a surfi cial aquifer, although surfi cial sands are present.

Floridan Aquifer System

### The Floridan aquifer system is divided into two major hydrostratigraphic horizons: the upper Floridan, which contains potable water, and the lower Floridan, which is saline. This discussion focuses on the upper Floridan aquifer, which is the principal source of water for the springs in the basin, as well as domestic, agricultural, and industrial supplies. The thickness of the potable water zone in the Floridan aquifer in the basin ranges from more than 900 feet in south-central Pasco County, to less than 200 feet along the Withlacoochee River in southeastern Citrus County, to less than 100 feet along the coast. A general uniform thinning of the upper Floridan aquifer’s potable zone occurs from south to north across the basin. The vertical extent of potable ground water inland is controlled by the occurrence of gypsum-bearing carbonates of the middle
confi ning unit, and the presence of sulfate-rich waters derived from the dissolution of sulfate minerals at the top of the unit. The average thickness of the potable zone in the Floridan aquifer is 400 to 600 feet in Hernando County and 200 to 300 feet in Citrus County. The Springs Coast Basin is mostly contained within the Northern West-Central Florida Groundwater Basin. The southwestern portion of
the basin is situated in the Central West-Central Florida Groundwater Basin. Ground water in both basins derives from rainfall. Approximately 1,700 mgd of ground water discharge from 27 coastal springs. 

# 42 Water Quality Assessment Report: Springs Coast

### The recharge potential for the Floridan aquifer in the basin is primarily controlled by the thickness and composition of the surfi cial sediments overlying the aquifer and the presence of karst topography. Other factorsaffecting recharge rates include the development of surface drainage; variations in head gradients between surface water, the surfi cial aquifer system, and the Floridan aquifer system; and aquifer permeability. Generally, high recharge rates occur where limestone is near the landsurface, or where overlying sediments are lacking in low-permeability confi ning materials. The presence of sinkholes, with their associated internal drainage of surface water, also induces higher recharge to the Floridan aquifer system. Lower recharge rates occur where confi ning materials overlying the aquifer retard the downward vertical movement of water, or where an upward gradient is present between the Floridan and surfi cial aquifer systems. Recharge is variably low to nonexistent in the Coastal Swamp region, with estimated recharge values of -9 inches (discharge) to 11 inches per year. This is primarily an area of regional Floridan aquifer discharge, with only localized recharge over very short distances contributing to spring discharge. Recharge in the Tsala Apopka Plain is similarly low, due to a diminished downward vertical gradient between surface waters or the surfi

- cial aquifer and the Floridan aquifer. Ground water discharge also occurs along sections of the Withlacoochee River south and east of Tsala Apopka. Accordingly, recharge estimates in the region range from less than 1 inch to 9 inches per year. Moderate to high recharge occurs in theCoastal Lowlands and Brooksville Ridge physiographic regions. Potential recharge of 3 to 16 inches occurs in the Coastal Lowlands, with 7 to 11 inches reported over land areas near the spring complexes.Recharge estimates in the Brooksville Ridge region are very high, ranging from 9 to 22 inches per year, because this area contains karst terrainwith internal drainage to the upper Floridan aquifer. Sinkholes are abundant, the land surface is generally very well drained, and the water table isrelatively deep. Surface waters are not abundant, and there are no permanent streams or extensive wetlands. These factors maximize recharge,
because infi ltration is rapid and surface runoff is nonexistent. The vulnerability of the Floridan aquifer system in the basin correlates with recharge estimates. Because of the porous karst terrain, the potential for ground water contamination in the Brooksville Ridge area is very high. The rest of the basin also has a high ground water contamination potential. This does not indicate that ground water contamination will occur, only that it could occur if pollutant sources were present. Potential pollutant sources in the Springs Coast Basin include landfills, borrow pits, stormwater ponds, septic systems, wastewater treatment facilities, and urban and agricultural runoff. Ground water may also be contaminated through the inadvertent release or spilling of industrial or agricultural chemicals or waste products. 

# 43 Water Quality Assessment Report: Springs Coast

### Ground Water–Surface Water Interactions The Brooksville Ridge is an area of high elevation, characterized by

ro lling sandhills, that extends along the eastern side of the Springs Coast Basin from north-central Citrus County south-southeastward through central Hernando County and southeast through east Pasco County. Although the regional confi ning unit between the surfi cial aquifer andupper Floridan aquifer is thickest along the Brooksville Ridge, its integrity is variable in this area. Karst activity has created large breaches in the
confi ning unit, many of which appear at the surface as relatively deep lakes. Due to the large head differences between the surfi cial and upper Floridan aquifers, the presence of sinkholes that breach the confi ning unit, and the availability of thick, surfi cial sands that act as reservoirs, recharge along the Brooksville Ridge can be quite high. In karst areas such as this, the formation of a unique type of sinkhole called a solution pipe is common. Solution pipes are formed by the collapse
of surfi cial material into long, vertical cavities that have been dissolved in the upper portion of the limestone. In most cases, a natural plug of sands and clays caps the solution pipes. If the cap is washed out, however, theresulting solution pipe sinkhole can act as a direct conduit for the movement of stormwater into the upper Floridan aquifer. Solution pipe sinkholes often form in the bottom of stormwater retention basins, where the capping plug is thinner. Catastrophic failure can occur if the increased hydraulic pressure exceeds the capacity of the capping plug. Solution pipes act as natural drainage wells and can drain large stormwater basins.Most of the springs in the basin lie in or near the freshwater/saltwater transition zone, a brackish zone in the upper Floridan aquifer where seaward-moving fresh water meets landward-moving salt water. As a result of their proximity to the transition zone, many of the basin’s springs discharge brackish water. The high salt content of many of these springs indicates that Gulf water has intruded through interconnected solution conduits gulfward of the springs. In general, springs located farther inland
are farther from the transition zone and therefore have fresher water. Asharp boundary is not present in coastal aquifers because of mechanical dispersion and tidal or water level fl uctuations caused by changes in recharge or pumpage over time. Instead, a dynamic equilibrium is established that
causes fresh water and salt water to mix and form a transition zone. There are approximately 140 active wastewater treatment facilities in the ground water basins of the Crystal, Homosassa, Chassahowitzka, Weeki Wachee, and Aripeka Spring Complexes. These facilities have a total permitted capacity of 15.6 mgd, and their average volume of processed wastewater is approximately 9.2 mgd. Effl uent from treatment facilities is disposed of in several different ways. A majority use percolation ponds. Several studies in the mid-1990s documented that some effluent percolation ponds in the basin drain extremely rapidly because they have highly porous bottoms composed of clean, fi ne-grained fi lter material. Since low-permeability confi ning units are either not present in the basin, or are frequently breached by sinkholes, treated effl uent can rapidly percolate directly into the Floridan aquifer system. 

# 44 Water Quality Assessment Report: Springs Coast

### In Citrus County, levels of nitrate exceeding drinking water standards were detected in numerous wells monitoring large effl uent percolation ponds. The effect of effl uent on the Homosassa and Chassahowitzka Spring Complexes is probably insignifi cant, however, because the amount of nitrogen contributed from effl uent in these ground water basins is low. In the Weeki Wachee ground water basin, the nitrogen from effl uent is high, but the treatment plants are dispersed over a very large area and most are located far from the spring. Also, the low nitrogen isotopic ratios inthe springs indicate an inorganic source, most likely from fertilizer application. In the Aripeka ground water basin, the nitrogen from effl uent may contribute some nitrogen to the Aripeka Springs Complex, because the Hudson wastewater treatment plant is located approximately 3.5 miles from the spring. However, the plant is probably not the dominant nitrogen source because, like Weeki Wachee Springs, the low nitrogen isotopic ratios indicate an inorganic fertilizer source.

Ground Water Usage Water supply in the Springs Coast Basin is derived principally from the

u pper Floridan aquifer. In 1996, ground water use in the basin was estimated at 80 mgd, or 94 percent of total water use, compared with 5.5 mgd of surface water. Hernando County accounted for about 45 percent (38.3 mgd) of total water use, compared with 40 percent for Pasco County and 15 percent for Citrus County. The largest use of water was for potable supply (57.9 mgd, or 68 percent). About 30.8 mgd are withdrawn from within Pasco County for potable supply. The basin contains more than500 public supply wells, according to the Florida Department of Environmental Protection’s (Department’s) Public Water System (PWS) Database. The largest wellfi elds are operated by Hernando County West Utilities (33 wells), Pinellas County Utilities (31 wells), Hudson Waterworks (17 wells), and Tampa Bay Water (17 wells). Public supply constitutes the greatest water use in the basin, with mining activities a distant second. In addition, 2 wellfi elds in Pasco County serve as a major source of public water supply for the Tampa Bay area (which lies outside the basin) through Tampa Bay Water: the Cross
Bar Ranch and North Pasco wellfields. Rates of ground water withdrawals from these facilities in 1996 were 20.2 mgd and 1.6 mgd, respectively. Most of the area supplying Tampa Bay Water that falls within the Springs Coast Basin is considered unsuitable for future ground water development. In some areas, such as Pasco County, wetlands are drying up as a result of pumping. Large ground water withdrawals in coastal Pasco, Hernando,
and Citrus Counties have also increased saltwater intrusion and the contamination of water supplies. In 1998, the SWFWMD conducted a water supply assessment for 4 regions within its boundaries. The majority of the Springs Coast Basin was contained in the northern water supply planning region, which includes Citrus, Hernando, and Sumter Counties and portions of Marion, Levy, and Lake Counties. Water supply demands for the northern region were projected to grow from 186.4 mgd in 1995 to 246.1 mgd in 2020, an increase of about 60 mgd (32 percent).

Water Use Caution Areas In 1989, the SWFWMD designated the Northern Tampa Bay Water

U se Caution Area (WUCA), which includes the southernmost portion of the Springs Coast Basin (southern Pasco County and Pinellas County). Under Section 373.036, F.S., and Subsection 62-40.520(1), F.A.C., each water management district in the state must identify WUCAs in which potential water shortages, considerable reductions in water levels,

### saltwater intrusion, or other degradations may occur within 20 years, and must develop management plans to address its water resource problems. In these areas, existing and anticipated sources of water and conservation efforts may not be adequate to supply water for all existing legal uses and reasonably anticipate future needs, and still sustain water resources and related natural systems. Five constraints are considered in establishing
these WUCAs:

• Impacts to native vegetation, primarily wetlands;
• Impacts to minimum fl ows and levels, primarily spring fl ows; • Impacts to ground water quality in terms of increased saltwater

intrusion;
• Impacts to existing legal users; and
• Failure to identify a source of supply for future development.

Ground Water Quality Issues Overall ground water quality in the Springs Coast Basin is very good.

H owever, point and nonpoint source threats to ground water quality exist and may become greater concerns with population growth and changing land uses. A variety of waste sites, some of which are regulated by state and federal programs, threatens the potable ground water supply. However, the quality of ground water that discharges to springs and estuaries is alsothreatened by point sources of wastewater, as well as nonpoint source activities that add nutrients to the Floridan aquifer.

Potential Threats to the Potable Water Supply

### Ground water quality in the basin is affected in some areas by contaminant sources that are being addressed by several programs managed by the Department. Figure 2.3 shows known sources of contamination in the Springs Coast Basin. Department databases include the following sites or
facilities: 

# 47 Water Quality Assessment Report: Springs Coast

### Figure 2.3: Ground Water Usage and Known Contaminant Sources in the Springs Coast Basin 

# 48 Water Quality Assessment Report: Springs Coast

### • Federal Superfund Sites: One Superfund site in the basin, Stauffer Chemical in Tarpon Springs, is on the National Priority List.
• State Waste Cleanup Program Sites: There are two state Waste

Cleanup Program sites in the basin: Alaric, Inc. and APF Industries.
• Petroleum Contamination Monitoring Sites: The basin contains

more than 1,600 known petroleum contamination monitoring sites. These sites are undergoing ground water monitoring, and some are undergoing cleanup. Public or private drinking water supplies affected by petroleum contamination are protected in one of several ways: (1) the affected well is decommissioned and water is provided from an alternative source, (2) treatment is provided at the water plant, or (3) for affected residential wells, activated carbon fi lters are installed to remove the contamination and meet drinking water
standards.
• State Dry Cleaning Program Sites: About 77 dry cleaning program sites have been identifi ed in the basin. Affected water supplies are being addressed as described for petroleum facilities.

• Brownfi eld Sites: Two brownfi eld sites have been identifi ed: the Clearwater Area and the Young Rainey Star Center Area.

• Delineated Areas of Ground Water Contamination: Eight areas

of ground water contamination have been identified by the Department’s Delineation Program (regulated under Rule 62-524, F.A.C., New Potable Water Well Permitting in Delineated Areas). The contaminant of concern is ethylene dibromide, an agrichemical and petroleum fuel additive that is now banned from use.

Sources of Nutrients Threatening Ground Water Quality and Springs 

### A major concern in the Springs Coast Basin is the increased nitrate loadings observed in the major springs groups. While the dominant source of nitrate found in the springs is inorganic in nature (i.e., originating from the residential and commercial use of fertilizers), organic sources may still contribute signifi cant quantities in other areas, or on a local scale. The agricultural application of fertilizers is also a potential source of inorganic nitrogen in the basin. Sources of organic nitrogen include sewage effl uent disposal, the land disposal of sewage sludge or treated wastewater, effl uent from septic tanks, agricultural activities (poultry, dairy, and cattle), and the application of potentially nutrient rich (with nitrogen and phosphorus) reclaimed water as irrigation. Nutrient concentrations in the Floridan aquifer system in the basin aretypically very low. Nitrate is easily leached into ground water, where it disperses through the aquifer system. Natural inputs of nitrogen (e.g., organicdecay) have always supplied very low levels of nitrate to the aquifer. However, anthropogenic sources (e.g., fertilizers and septic tanks) are increasing the input of nitrates into the system. As expected, nitrate concentrations are low in most areas of the basin; in southwestern Hernando County, however, the leaching of nitrogen has increased nitrate concentrations in the aquifer. Recent water quality studies 

# 49 Water Quality Assessment Report: Springs Coast

### indicate that 95 tons of nitrate per year are discharged from Weeki Wachee Springs. Also, the dramatic increase in nitrate concentrations in the spring since the early 1970s is most likely due to the increased human population in and near Spring Hill. Recent studies show that the nitrate in the Floridan aquifer system originates from inorganic fertilizers applied to turf acreage near the four major spring complexes. However, the basin’s growing population will likely increase the signifi cance of organic sources of nitrogen, such as septic systems and wastewater treatment plants.



## Major Water Quality Trends

Nitrate Contamination in Spring Discharges Nitrate concentrations have been increasing in a number of major

sp ring groups in the SWFWMD, including Homosassa, Chassahowitzka, and Weeki Wachee Springs. The most dramatic increase in nitrate occurs in the Weeki Wachee main spring, where concentrations have increased from less than 0.02 milligrams per liter (mg/L) in 1946 to 0.88 mg/L
in 2004. Nitrate concentrations in ground water in undeveloped areas of Citrus, Hernando, and Pasco Counties were compared with nitrate concentrationsin ground water discharging from the springs. The spring water concentrations exceeded natural background ground water concentrations. Because the enrichment of nitrate to the level occurring in the spring water does not result from natural processes, human-induced contamination of the ground water must be occurring somewhere within the recharge area of the springs. Although the nitrate concentrations (0.18 to 0.88 mg/L) in the coastal springs of Citrus, Hernando, and Pasco Counties are considerably lower than those of springs in the surrounding basins, such as Lithia, Buckhorn, and Rainbow Springs, they are still of great concern. Even at these low concentrations, water discharging at the rate of approximately 900 cfs from the main springs and smaller, surrounding springs contains an annual nitrate load of over 360 tons. The coastal rivers rapidly deliver this nitrate to the estuaries along the Gulf Coast. As nitrate concentrations continueto rise, it is likely that algae blooms will increase in frequency and duration, and the vegetative composition of these estuarine aquatic systems will
be altered. The water discharging from the springs has probably not been in theaquifer for more than a few decades at most. Nitrogen isotopic data suggest that the dominant source of nitrate currently discharging from thesprings is inorganic. Residential and golf course turf and landscape fertilizers are the likely sources. Organic sources, although regionally less signifi

- cant, may still elevate nitrate concentrations to high levels on a local scale. Organic sources include naturally occurring organic decay; sewage effl uent disposal; the land disposal of sewage sludge; effl uent from septic tanks; the land disposal of septage sludge; and poultry, dairy, and cattle operations.

## Watershed Management Activities and Processes

Over the years, management plans and activities in the basin have been implemented to eliminate wastewater discharges; reduce the discharges of polluted stormwater from urban and agricultural areas; and protect,preserve, and restore special areas. The following section describes historical, current, and ongoing activities and processes to address water quality problems. Much of the progress in the Springs Coast Basin in developing water quality restoration plans and implementing watershed and water quality improvements is attributable to coordinated local, state, and regional efforts. In particular, local organizations and initiatives have provided leadership in waterbody restoration and preservation efforts. Many plans share common goals, and their implementation is based on various groupsplaying critical roles in planning, funding, managing, and executing projects. The Department continues to coordinate its efforts with these entities to obtain data, improve monitoring activities, and exchange information through periodic meetings. A number of major restoration initiatives, if continued, will have signifi cant positive effects on the basin’s water quality.

Crystal River/Kings Bay Surface Water Improvement and Man agement Plan As discussed earlier, the original Crystal River/Kings Bay SWIM Plan

w as prepared and approved in 1989, and the plan was updated in 2000. Many of the projects identified in the original SWIM plan were for studies and data collection efforts—diagnostic tools for resource managers— designed to provide an insight into the intricacies of the system. An emphasis was placed on the development of a comprehensive understanding of the water chemistry of Kings Bay and Crystal River. The results of this diagnostic work provided the necessary technical information to develop the management strategies for the 2000 SWIM plan update. Ongoing work on fi ve coastal rivers (including Crystal River)and their nutrient assimilative capacity may recommend expanding management actions farther down the rivers and perhaps to the nearshore gulf

systems. The Crystal River/Kings Bay SWIM Plan has established the following goals:

• Achieve and maintain water clarity that will provide an annual average horizontal Secchi depth reading of 45 feet,

• Stabilize or remove the sediment from areas that have been demonstrated to contribute to reduced water clarity as a result of sediment resuspension,
• Revegetate denuded areas with desirable submerged aquatic

vegetation, and
• Restore vital aquatic habitat. 

# 51 Water Quality Assessment Report: Springs Coast

### Proposed projects in the SWIM plan include the improvement of stormwater management systems for sediment and debris control, the removal of accumulated sediment from targeted areas of Kings Bay, revegetation following sediment removal, water quality monitoring, and
the removal of accumulated Lyngbya sp. from targeted areas of Kings Bay. Lyngbya is a hairlike, fi lamentous alga that grows in large mats on the surface and bottom of the bay.

Land Acquisition Several agencies have land-buying programs in the basin. These

i nclude the Department’s Conservation and Recreation Lands Program, the SWFWMD’s Save Our Rivers (SOR) Program, and Preservation 2000 and its successor, Florida Forever. The lands targeted for acquisition include riverine swamps and fl ood conveyance corridors, particularly those
downstream of fl ood detention areas, those in areas of heavy development pressure, or those adjacent to other SWFWMD or public land holdings. Usually, these land acquisition programs emphasize the preservation ofnatural systems and the enhancement/preservation of water quality. However, because the lands purchased are often fl ood-prone wetland areas, the acquisitions also prevent development in historical fl ood storage areas. A number of sites in the Springs Coast Basin have been formallyevaluated by SOR and approved for acquisition. These include the Chassahowitzka Riverine Swamp Sanctuary, Weeki Wachee Preserve, AnnutteligaHammock, Starkey Wilderness Preserve, Pasco 1, and Hidden Lake Property. The acquisition of the Annutteliga Hammock and Pasco 1 projects is ongoing, while the purchase of the other projects has been completed. In 1990, Penny for Pinellas was created. The principal goal of this one-cent local option sales tax was to make funds available for the county’s endangered lands program. In 1997, voters extended the tax for 10 years.

Nitrate Remediation WorkgroupThe Springs Coast Comprehensive Watershed Management team initiate d the Nitrate Remediation Workgroup to address impacts to the region’s springs and drinking water sources caused by increasing nitrate levels in ground water and surface water. The workgroup is composed of citizens, industry, and government representatives, including the SWFWMD. In 2001, more than 2,900 surveys were mailed to residents in the Chassahowitzka, Homosassa, Kings Bay, and Weeki Wachee areas to help
determine how homeowners in the area fertilize and water their lawns and gardens. The information gathered was used to develop an educational program on fertilization and irrigation practices for homeowners, in order to reduce water quality impacts to the basin’s springs and spring-fed rivers.

Pasco County Watershed Management Plan The Anclote River Watershed Master Plan (Phase I) was completed in

F ebruary 2001 by Camp Dresser & McKee Inc. for Pasco County undera cooperative project with the SWFWMD. Phase I includes the development of a stormwater model of the watershed and preparation of fl ood insurance maps. The next phase will address water quality and natural

systems. 

# 52 Water Quality Assessment Report: Springs Coast

### Pinellas County Watershed Management PlanIn 1989, Pinellas County began a program of surface water mana gement based on the watershed boundaries of its 52 watersheds. The watershed management planning initiatives that evolved from this were comprehensive in nature, including flood control, erosion control, conservation, water quality restoration and protection, natural systems conservationand restoration, and the protection of coastal water quality, biodiversity, and estuarine productivity. The county’s Stormwater Management Plan incorporates these aspects of water resource planning into a single comprehensive plan. Additionally, in 1993 the county developed a priority order for the development of individual plans for the 52 watersheds. By 1995, the county had completed basin studies for Belleair Creek, Bishop Creek, Mullet Creek, Allen’s Creek, and Lake Tarpon basin/watersheds. In 2001, the Lake Seminole Watershed Management Plan was completed; the plan provides a detailed restoration plan for the watershed and lake.

City of Clearwater The city of Clearwater has completed two watershed management

p lans with water quality sections. The fi rst plan was completed in June 1997 for the Alligator Creek watershed. The second was completed in August 2001 for the Stevenson’s Creek watershed. The city published a surface water quality monitoring report until 1995.

Agricultural Best Management Practices The FWRA authorizes the Florida Department of Agriculture and

C onsumer Services (DACS) to develop interim measures and agriculturalbest management practices (BMPs). Additional authority for agricultural BMPs is provided in legislation on nitrates and ground water (Section 576.045, F.S.), the Lake Okeechobee Protection Program (Section 373.4595, F.S.), Agricultural Water Conservation (Section 570.085, F.S.), and Florida Right to Farm Act Amendments (Section 823.14, F.S.). While BMPs are often adopted by rule, they are voluntary if not covered by regulatory programs. If they are adopted by rule and the Department
verifi es their effectiveness, then implementation provides a presumption of compliance with water quality standards. Over the last several years, DACS has worked with agriculturists, soil and water conservation entities, the University of Florida’s Institute of Food and Agricultural Sciences, and other major interests to improve product marketability and operational effi ciency by implementing agriculturalBMPs, while at the same time promoting water quality and water conservation objectives. In addition, programs have been established and are being developed to create a network of state, local, federal, and private sources of funds for developing and implementing BMPs. 

# 53 Water Quality Assessment Report: Springs Coast

### Manuals for Best Management Practices 

### To encourage growers to use BMPs, manuals have been published for a number of agricultural industries, including container-grown plants, blended fertilizer plants, agrichemical handling and farm equipment maintenance, cow/calf operations, aquaculture, citrus, and landscaping. Many of these manuals can be downloaded at http://www.dep.state.fl .us/ water or http://www.fl oridaagwaterpolicy.com.Manuals for row crops, equine or horse farms, and ornamental nurseries are currently being developed. The use of a BMP manual alone,however, does not afford a presumption of compliance with the Department’s water quality standards. In general, qualifying for a presumption of compliance requires that a site-specifi c BMP assessment process be in place or that practices being used have been proven effective through research
and demonstration.

# Chapter 3: Surface Water Quality Assessment

Scope of the Assessment

This chapter presents the results of an updated assessment of surface water quality in the Springs Coast Basin. The primary purpose of the assessment is to determine if waterbodies or waterbody segments are to be placed on the Verifi ed List of impaired waterbodies. The listing will be in
accordance with evaluation thresholds and data suffi ciency and data quality requirements in the Identifi cation of Impaired Surface Waters Rule (IWR) (Rule 62-303, Florida Administrative Code [F.A.C.]). The results of theassessment will be used to identify waters in the basin for which total maximum daily loads (TMDLs) will be developed. The chapter describes the planning units in the basin used as a basis for the assessment. A section on each planning unit contains a generaldescription and summary of key water quality indicators (such as nutrients, chlorophyll a , dissolved oxygen [DO], and microbiological parameters). Permitted discharges, land uses, ecological status, and water quality improvement plans and projects are summarized for each planning unit. The discussion notes where applicable surface water quality criteria have been exceeded and summarizes the report’s fi ndings in maps, noting the impaired waterbodies in each planning unit. The chapter also containsbackground information on sources of data and on designated use attainment, and explains the state’s integrated water quality assessment process. While impaired waters and their causative pollutants are identifi ed, itis not within the scope of this report to identify discrete sources of impairments. Information on the sources of impairment will be developed in subsequent phases of the watershed management cycle, including TMDL development and implementation. Appendix A contains a discussion of the legislative and regulatory background for TMDL development and implementation. Appendix B contains supplementary information on the basin’s ecology. Appendix C provides additional information on reasonable assurance. As part of the 303(d) assessment of the Springs Coast Basin, the Florida Department of Environmental Protection (Department) received documentation from Pinellas County designed to provide reasonable assurance that proposed pollution control mechanisms would effectively address the nutrient-related impairment of Lake Seminole. While the fi nal agency action on this submittal will not occur until adoption of the Verifi ed List of impaired waters for the Group 5 basins, the Department has concluded that the Lake Seminole Reasonable Assurance Plan (plan) provides reasonable assurance that the lake will be restored. As such, the Department will approve the reasonable assurance proposal as part of the list adoption and will place Lake Seminole in assessment Category 4b. 

# 55 Water Quality Assessment Report: Springs Coast

### In addition to providing detailed information about proposed pollution control mechanisms, including an implementation schedule, funding sources, and local commitments, the plan provides specifi c water quality targets that interpret the narrative nutrient criteria. The Department has concluded that the proposed control measures will achieve the water quality targets, which will implement the lake’s applicable water quality standards. Appendix D provides the methodology used to develop the Planning

## Update on Strategic Monitoring and DataGathering Activities During Phase 2

During Phase 2 of the watershed management cycle, strategic monitoring and data-gathering activities focused fi rst on waters on the 1998 303(d) list, followed by waters that were placed on the Planning List through the IWR assessment alone. The majority of the strategic monitoring work was conducted by the Department’s Southwest District staff and included both chemical and biological monitoring and data upload to STO rage and
RETrieval (STORET) databases. Data-gathering activities included working with environmental monitoring staff in the Southwest Florida Water Management District (SWFWMD) and local and county governments to obtain applicable monitoring data from their routine monitoring programs and special water quality projects in the basin. Twenty-two waterbody segments on the Planning List and the 1998 303(d) list needed further data to verify impairment. Parameters included DO, nutrients, coliforms, unionized ammonia, biological oxygen demand (BOD), total suspended solids (TSS), and mercury in fi sh. Fifteen waterbody segments were verifi ed impaired for at least oneparameter in the Springs Coast Basin as the result of strategic monitoring and data-gathering activities in Phase 2. Appendix E lists the water quality monitoring stations used in the assessment.



## Sources of Data

The assessment of water quality in the Springs Coast Basin includes ananalysis of quantitative data from various sources, some of which are readily available to the public. These sources include the U.S. Environmental Protection Agency’s (EPA’s) Legacy and “new” STORET databases, the U.S. Geological Survey (USGS), and the Florida Department of Health (DOH). The STORET databases contain water quality data from a number of sources, including the Department, water management districts, 

# 56 Water Quality Assessment Report: Springs Coast

### local governments, and volunteer monitoring groups. Appendix D contains a detailed description of STORET and the methodology used to develop the Planning and Verifi ed Lists, based on the IWR. Table 3.1 summarizes the individual data providers who contributed to the IWR Database for the Springs Coast Basin for the period of record used
in this assessment. Figure 3.1 contains a pie chart showing the amount of data provided by each source. Individual data providers who contributed to the IWR Database for the Springs Coast Basin during the period of record used in this assessment include the USGS, Department’s Southwest District, DOH, Florida Fish and Wildlife Conservation Commission, Pinellas County Department of Environmental Management, Hillsborough County, Florida LakeWatch, and SWFWMD. In 2002, the Department created the IWR Database to evaluate data in accordance with the methodology prescribed in the IWR (Rule 62-303, F.A.C.). For the Planning List assessment, the data evaluation period of record is 10 years, and for the Verifi ed List, 7.5 years. Table D.2 in Appendix D shows the periods of record for the Verifi ed and Planning Lists
in the fi rst basin rotation cycle. Data collected between January 1, 1999, and June 30, 2006, were evaluated to establish the Verifi ed List for the Springs Coast Basin (IWR Run 29). To support listing decisions, the evaluation of water quality in this basin also includes qualitative information drawn from data in technical reports and documents that are not yet included in the database. Some of these sources include historical water quality or ecological information that was not uploaded to the database because of its qualitative treatment
of issues.

## Attainment of Designated Use

While the designated uses of a given waterbody are established using the surface water quality classifi cation system described in Chapter 2, it is important to note that the EPA uses slightly different terminology in itsdescription of designated uses. Because the Department is required to provide use attainment status for both the state’s 305(b) report and the state’s 303(d) list of impaired waters, the Department uses EPA terminology when assessing waters for use attainment. The water quality evaluations and decision processes that are defi ned in Florida’s IWR for listing impaired waters are based on the following designated use attainment categories:

Aquatic Life Use Support-Based Attainment Primary Contact and Recreation Attainment
Fish and Shellfi sh Consumption Attainment Drinking Water Use Attainment
Protection of Human Health

## Integrated Report Categories and Assessment Overview

The EPA has requested that the states merge their reporting requirements under the Clean Water Act for Section 305(b) surface water quality reports and Section 303(d) lists of impaired waters into an Integrated Water Quality Monitoring and Assessment Report Guidance (Wayland, 2001). This Assessment Report integrates the 303(d) list and the 305(b) report for the Springs Coast Basin.Following the EPA’s guidance, the Department delineated waterbodies or waterbody segments in each of the state’s river basins, assessed them for impairment based on individual parameters, and then placed them into
one of fi ve major assessment categories and subcategories. These categoriesprovide information on a waterbody’s status based on water quality, suffi ciency of data, and the need for TMDL development (Table 3.3)

. This Assessment Report contains a comprehensive evaluation of waterbodies that fall into Integrated Report Categories 1 through 5 in the table. Not enough recent data on chemistry, biology, and fi sh consumption advisories have been collected; therefore, currently only a few water bodiesor waterbody segments statewide fall into Category 1 (attaining all designated uses). In particular, fi sh tissues in many waterbodies statewide have not been tested for mercury. Out of 158 waterbodies or waterbody segments in the Springs Coast Basin, none are in Category 1.More waterbodies and segments statewide fall into Category 2 (attaining some uses but with insufficient data to assess completely) than Category 1 (attaining all uses), because monitoring programs can sometimes provide suffi cient data for partially determining whether a designated use in a particular waterbody is attained. There are 23 waterbody segments in the basin which fall into Category 2. Most waterbodies in the state, however, fall into Category 3 (having
insufficient data). In the Springs Coast Basin, the breakdown of waterbodies or segments in Category 3 is as follows:

• Category 3a—49 segments for which no data are available to determine their water quality status,
• Category 3b—46 segments with some data but not suffi cient data for making any determinations, and 

## Understanding the Terms “Pollutant” and “Pollution”

For purposes of the TMDL Program, pollutants are chemical and biological constituents, introduced by humans into a waterbody, that may result in pollution (water quality impairment). There are other causes ofpollution, such as the physical alteration of a waterbody (for example, canals, dams, and ditches). However, TMDLs are established only for impairments caused by pollutants (a TMDL quantifieshow much of a given pollutant a waterbody can receive and still meet its designated uses).

Waterbodies that are verified impaired due to specified pollutants, and therefore require a TMDL, are listedunder Category 5 in the Integrated Assessment Report; waterbodies with water quality impairments due to other causes, or unknowncauses, are listed under Category 4c. Although TMDLsare not established for Category 4c waterbodies, these waterbodies still may beaddressed through a watershed management program (for example, the Kissimmee River restoration). 

# 59 Water Quality Assessment Report: Springs CoastTable 3.3: Categories for Waterbodies or Waterbody Segments in the Integrated Report

Category Description Comments
1 Attaining all designated uses If use attainment is verified for a waterbody or segment that was previously listed as impaired, the Department will propose that it be delisted.

2 Attaining some designated uses
and insufficient or no information or data are present to determine if remaining uses are attained If attainment is verified for some designated uses of a waterbody or segment, the Department will propose partial delisting for the uses attained. Future monitoring will be recommended to determine if remaining uses
are attained.

3a No data and information are present to determine if any designated use is attained Future monitoring will be recommended to determine if designated uses
are attained.

3b Some data and information arepresent but not enough to determine if any designated use is
attained Future monitoring will be recommended to gather sufficient information and data to determine if designated uses are attained.

3c Enough data and information are present to determine that one or more designated uses may not be attained according to the Planning List methodology A waterbody or segment is potentially impaired for one or more designated uses. These waters will be prioritized for future monitoring to verify use attainment or impaired status

.

3d Enough data and information are present to determine that one ormore designated uses are not attained according to the Verified List methodology A waterbody or segment exceeds Verified List evaluation criteria andmay be listed as impaired at the end of Phase 2 of the watershed management cycle. However, the data have not yet been fully evaluated andthe waters have not been formally verified as impaired. Further monitoring and analysis may be necessary.
NOTE: This category is applicable only to the Status Report. Waters that pass the Verified List criteria at this stage of the process are placed in Category 5.

4a Impaired for one or more designated uses but does not require TMDL development because a TMDL has already been completed After the EPA approves a TMDL for the impaired waterbody or segment, the TMDL will be included in a Basin Management Action Plan to reduce pollutant loading toward attainment of designated use(s).

4b Impaired for one or more designated uses but does not require TMDL development because the water will attain water quality standards due to existing or proposed

measures Pollutant control mechanisms designed to attain applicable water quality standards within a reasonable time frame are either proposed or in place.

4c Impaired for one or more designated uses but does not require TMDL development because impairment is not caused by a pollutant This category includes waterbodies or segments that are impaired because of naturally occurring conditions or other causes of pollution. The impairment is not caused by specific pollutants. (See sidebar on previous page for a discussion of the difference between the terms “pollutant” and “pollution.”)

5 One or more designated uses is
not attained and a TMDL is required Waterbodies or segments in this category are impaired for one or more designated uses by a pollutant or pollutants. Waters in this category are included on the basin-specific Verified List adopted by the Department’s Secretary as Florida’s impaired waters list and submitted to the EPA as Florida’s 303(d) list of impaired waters at the end of Phase 2.

Note: The descriptions in Table 3.3 are consistent with the EPA’s integrated assessment categories. In the Status Reports for Groups 1 through 3 and in the Assessment Reports for Groups 1 through 2 that were previously produced, Categories 4b and 4c were reversed. That is, the description of Category 4b was previously listed as Category 4c, and the description of Category 4c was listed as Category 4b. 

# 60 Water Quality Assessment Report: Springs Coast

### • Category 3c—2 segments that are potentially impaired based on the Planning List criteria.

A number of waters either fail to meet water quality standards for DO or show signs of biological stress or nutrient impairment. According to the IWR, specifi c pollutants causing DO exceedances or biological stress, or an underlying nutrient imbalance creating an imbalance in fl ora or fauna, must be documented for a waterbody or segment to be listed as impaired. Sometimes these conditions cannot be linked to a causative pollutant, and sometimes they may refl ect natural background conditions. Currently, 17 waterbodies in the basin are designated as being in Category 4. This category includes those waterbodies/segments that are impaired but do not require a TMDL for one of three reasons:

• Category 4a—No segments for which a TMDL has already been

developed,
• Category 4b—1 segment for which there is reasonable assurance that

the designated use of an impaired waterbody will be attained by an existing or proposed pollutant control measure, and
• Category 4c—17 segments for which the impairment is not attributable to a pollutant or pollutants, but is due to natural conditions or physical/hydrologic alterations to the waterbody.

Finally, 35 waterbodies in the basin are in Category 5. These impaired
waterbodies are on the Verifi ed List of impaired waters adopted by the Department’s Secretary and will require TMDLs. Chapter 5 of this report discusses in detail the waters in this category.



## Planning Units

The Springs Coast Basin encompasses approximately 800 square miles and a complex hydrologic system. To provide a more detailed geographic basis for identifying and assessing water quality improvement activities, thebasin was subdivided into smaller areas called planning units. A planning unit is either an individual large tributary basin or a group of smaller adjacent tributary basins with similar characteristics. Planning units helporganize information and management strategies around prominent watershed characteristics. Water quality assessments were conducted for waterbody segments within planning units. Each of these smaller, hydrologically based drainage areas within a planning unit is assigned a unique waterbody identifi cation number (WBID). Waterbody segments are assessment units (or geographic information system polygons) that the Department used to define waterbodies when it biennially inventoried and reported on water quality to the EPA under Section 305(b) of the federal Clean Water Act. These WBIDs
are the assessment units identifi ed in the Department’s lists of impaired

### waters submitted to the EPA in reports under Section 303(d) of the Clean

Water Act. The Springs Coast Basin contains fi ve planning units: Crystal River/ Kings Bay, Homosassa River, Chassahowitzka River, Middle Coastal, and Anclote River/Coastal Pinellas County. Table 3.4 describes these planning units, and Figure 3.2 shows their locations and boundaries. The remainder of this chapter provides a general description of each planning unit, information on land use and potential point sources of pollution, water quality assessments for individual waterbody segments, and summaries of ecological issues and watershed quality improvement plans and projects. Appendix E of this report provides, by planning unit, a list of waterquality monitoring stations, the integrated assessment (Master List) summary, and trend data. Appendix F includes summary information, by planning unit, for permitted wastewater treatment facilities, Superfund sites, and permitted landfi ll facilities. Appendix G lists Level I land uses, by planning unit.



## Assessment by Planning Unit

• Crystal River/Kings Bay Planning Unit

General Description 

### The Crystal River/Kings Bay Planning Unit covers about 78 square miles and contains 12 segments with WBIDs (Figure 3.3)

.Crystal River and Kings Bay are located in Citrus County, approximately 60 miles north of Tampa. The tidally infl uenced Kings Bay is the headwaters of Crystal River, which forms at the northwest corner of the bay. The Kings Bay Springs Complex, the largest spring complex in the basin and the fourth largest in Florida, contains more than 30 springs; it discharges approximately 630 million gallons per day (mgd). Because of their regional signifi cance, both Crystal River and Kings Bay are designated as Outstanding Florida Waters (OFWs) and Surface Water Improvement and Management (SWIM) priority waters. The Crystal River Nuclear Power Plant lies along the coast, between the mouths of the Crystal and Withlacoochee Rivers. Table 3.4: Planning Units in the Springs Coast Basin

Planning Unit Description

Crystal River/ Kings Bay The planning unit, encompassing over 78 square miles, lies in the northern portion of the basin, in west Citrus County.

Homosassa River The planning unit, encompassing almost 90 square miles, is located in west Citrus County.

Chassahowitzka
River The planning unit, encompassing over 176 square miles, lies in the central portion of the basin, in
southern Citrus and northern Hernando Counties.

Middle Coastal Located in the south-central portion of the basin and encompassing over 466 square miles, the planning unit covers northwestern Pasco County and western Hernando County.

Anclote River/
Coastal Pinellas County The planning unit, encompassing almost 252 square miles, comprises the southern portion of the basin, encompassing western Pinellas County from the Anclote River southward to Gulfport.

Water Quality Summary 

### Historical water quality in the Crystal River/Kings Bay system was good. In recent years, however, nitrate contamination has increased. Because nitrate concentrations discharging from the springs are 20 times higher than the natural ground water concentrations in the Floridan aquifer statewide, much of the nitrate entering the system comes from the ground water discharging from the springs. Water clarity in Kings Bay is primarily affected by the concentration of suspended solids in the water column. These result primarily from the resuspension of bottom sediments through wind action or physical
disturbance. Hunters Spring Park, which is part of the Kings Bay system, was closed to swimming during most of the summer of 2000 due to elevated levels of
total and fecal coliform bacteria. The cooling-water intake pipes for the Crystal River Nuclear Power Plant extend into the nearshore area, causing localized increases in water

temperature. Figure 3.3 , a composite map of the planning unit, shows waters on the 1998 303(d) list and the Planning List. Table 3.5 summarizes the water quality assessment status of all waterbody segments in the planning unit.

Notes:

1 The designation “stream” includes canals, rivers, and sloughs. The designation “lake” includes some marshes.

2 The state’s surface water classifications are as follows: Class I: Potable water supplies Class II: Shellfish propagation or harvesting Class III: Recreation, propagation, and maintenance of a healthy, well-balanced population of fish and wildlife Class IV: Agricultural water supplies Class V: Navigation, utility, and industrial use (there are no state waters currently in this class) 

# 65 Water Quality Assessment Report: Springs Coast3 The EPA’s 305(b)/303(d) Integrated Report categories are as follows: 1 —Attains all designated uses; 2 —Attains some designated uses; 3a —No data and information are available to determine if any designated use is attained; 3b —Some data and information are available, but they are insufficient for determining if any designated use is attained; 3c —Meets Planning List criteria and is potentially impaired for one or more designated uses; 3d —Meets Verified List criteria and is potentially impaired for one or more designated uses; 4a —Impaired for one or more designated uses and the TMDL is complete; 4b —Impaired for one or more designated uses, but no TMDL is required because an existing or proposed pollutant control mechanism provides reasonable assurance that the water will attain standards in the future; 4c —Impaired for one or more designated uses but no TMDL is required because the impairment is not caused by a pollutant; and 5 —Water quality standards are not attained and a TMDL is required.

4 The assessment categories listed in this column represent the status of each WBID as a whole, based on multiple parameters

. The hierarchy of assigning these categories is Category 5, then 4, then 3c, then 2, and then 3b, i.e., each WBID is assigned a category based on the highest category assigned to an individual parameter. For example, if WBID 9999 has one parameter as a Category 5, then this supersedes parameters at Category 3c or 2, and the WBID as a whole is classed as a Category 5.

### Point Sources: Figure 3.4 shows permitted wastewater treatment facilities, landfi lls, and delineated ground water contamination areas in the planning unit (see Noteworthy for a definition of point sources and discussions of environmental remediation and delineated ground water contamination areas). Appendix F lists the basin’s domestic and industrial surface discharge facilities, along with their permitted fl ows, by planning unit. It
also lists landfi lls or solid waste facilities, by planning unit. The Crystal River/Kings Bay Planning Unit contains 21 permitted domestic and industrial facilities. Four of them discharge greater than 0.1 mgd through surface water discharges or by land application of
the effl uent. There are no hazardous waste cleanup sites in the planning unit. The planning unit contains one active construction and demolition
debris landfi ll and one closed and monitored Class II solid waste landfi ll. Nonpoint Sources: Based on Levels I and II land use summary information, the predominant land use in the planning unit is urban and built-up (approximately 36 percent of the planning unit’s area). Other major land uses include upland forests (26 percent) and wetlands (25 percent). These land uses can be associated with nonpoint discharges of pollutants and eroded sediments (see Noteworthy for a defi nition of nonpoint sources). Appendix G provides summary information on Level I land uses in the basin, by planning unit. 

# 66 Water Quality Assessment Report: Springs Coast

### Ecological Summary 

### While aquatic vegetation is important to water clarity in the Crystal River/Kings Bay system, undesirable aquatic vegetation has been a problem since hydrilla was introduced in 1960. Most recently, Lyngbya , an undesirable fi lamentous alga, has dominated areas of Kings Bay, causing habitat destruction, use impairment, and odor problems. Floating plants and
Eurasian milfoil (Myriophyllum spicatum) are problems in the Crystal River.

• Homosassa River Planning Unit

General Description 

### The Homosassa River Planning Unit covers about 90 square miles and contains 8 segments with WBIDs (Figure 3.4)

. Like Crystal River, the Homosassa River is a coastal, spring-fed river/ estuarine system located in west Citrus County. Halls River is the only major tributary. The river, which has been designated as an OFW, extendsapproximately 6 miles from the Gulf of Mexico to its headwaters at Homosassa Springs. The springs discharge about 68 mgd.

Landfills, hazardous waste sites,the Department’s Dry Cleaning Solvent Cleanup Program sites, and petroleum facility discharges are also considered point sources. These sites havethe potential to leach contaminants into ground water and surface water. Identifying the source of waterbody impairment is an importantpart of assessing water quality and developing TMDLs. As part of this report, information is presented on point sources, including permitted facilities that discharge wastewater and landfills.



## Environmental Remediation

The National Priorities List (NPL) is a consolidated list of the uncontrolled hazardous waste sites that pose the greatest threatto public health or the environment. Sites are listed on the NPLupon the completion of a preliminary assessment, site inspection, and hazardous ranking system evaluation to determine their potential for adverse impacts and priority for corrective action. TheEPA Superfund program administers the cleanup of NPL sites.

The Department’s state-funded cleanup program administers thecleanup of contaminated hazardous waste sites when enforcement action taken against a responsible party is unsuccessful or when no responsible party is identified.



## Delineated Ground Water Contamination Areas

water in Florida. The Delineation Program is designed to ensure the protection of public health when consuming potable ground water supplies and to minimizethe potential for cross-contamination of adjacent ground water

resources.

The Delineation Program’s primary responsibilities are as follows: • Delineate areas of ground water contamination, • Implement a water wellconstruction permitting/application process that requires stringent construction standards, and • Require water testing after completion of the well to ensure the potable quality of the water source. Any newly constructed water wells in delineated areas, and existing water wells found to be contaminated, are remediated byinstalling individual water treatment systems or by connecting the users to public water supply systems.



## Nonpoint Sources and Land Uses

to lakes, rivers, and estuaries in a watershed, and into ground water supplies. Nonpoint sources also include atmospheric deposition and leaching from agricultural lands, urban areas, and unvegetated lands. The pollutants in runoff often include fertilizers, bacteria, metals, sediments, and petroleum compounds.

### Homosassa Springs area—have degraded the river’s water quality. The DOH and the Department found high concentrations of bacteria and nutrient enrichment. Nutrients increased from 1992 through late 1996 in the upper reaches of the river above Halls River. The Homosassa SpringsState Wildlife Park, with assistance from the SWFWMD and the University of South Florida, investigated the potential addition of bacteria and nutrients from the park’s wildlife to the headwaters of the river. These impacts were relatively minor. The predominant source of nutrients in the planning unit is golf course, residential turf, and landscape fertilizing. Septic tanks are also a signifi cant source.

Water Quality Summary 

### Historical water in the Homosassa River was good, and it remained good through the mid-1980s. A 1989 study, however, found signifi cant water quality degradation in the upper river, primarily due to the effects of septic tanks and treated wastewater effl uent. A salt wedge reaching upstream from the Gulf creates variations in salinity. Figure 3.4 , a composite map of the planning unit, shows waters on the 1998 303(d) list and the Verifi ed List. Table 3.6 summarizes the water quality assessment status of all waterbody segments in the planning unit.

Permitted Discharges and Land Uses 

### Point Sources: Figure 3.4 shows permitted wastewater treatment facilities, landfi lls, and delineated ground water contamination areas in the planning unit. Appendix F lists the basin’s domestic and industrial surface discharge facilities, along with their permitted fl ows, by planning unit. It
also lists landfi lls or solid waste facilities, by planning unit. The Homosassa River Planning Unit contains 23 permitted domestic and industrial facilities. None of them discharges greater than 0.1 mgd through surface water discharges or by land application of the effl uent. There are no hazardous waste cleanup sites in the planning unit. The planning unit contains two Class I solid waste landfi lls (one is active and the other is closed and monitored); one closed and monitored
Class II solid waste landfi ll; and two construction and demolition debris
landfi lls (one is active and the other is inactive). Nonpoint Sources: Based on Levels I and II land use summary information, the predominant land use in the planning unit is wetlands (approximately 48 percent of the planning unit’s area). Other major land uses include urban and built-up (22 percent) and upland forests (23 percent). These land uses can be associated with nonpoint discharges of pollutants and eroded sediments. Appendix G provides summary information on Level I land uses in the basin, by planning unit.

Homosassa River.

• Chassahowitzka River Planning Unit

General Description 

### The Chassahowitzka River Planning Unit covers about 176 square miles and contains 8 segments with WBIDs (Figure 3.5)

. The Chassahowitzka River is located in southwestern Citrus County approximately 6.5 miles south of Homosassa, just north of the Citrus– Hernando County line. The river begins at Chassahowitzka Springs, approximately 1.5 miles west of U.S. Highway 19 and just north of State Route 480. The springs discharge about 90 mgd. From there, the river fl ows westerly to the Gulf of Mexico through
about six miles of hardwood forests and low coastal marshland. Crab

# 71 Water Quality Assessment Report: Springs Coast

### Creek, Cabbage Creek, Baird Creek, Salt Creek, Potter Creek, Crawford Creek, Blue Run, Ryle Creek, and May Creek all flow directly to the Chassahowitzka River, while Chub Creek and Blind Creek fl ow to the Gulf of Mexico. The Chassahowitzka River and a number of creeks in the system are designated as OFWs.

Water Quality Summary 

### Water quality data for the Chassahowitzka River are limited. Limited historical data (collected before 1981) indicated that water quality was good. Data collected from 1992 through 1996 at selected springs are the most consistent data for this system. As with the other coastal spring systems in the basin, nitrates are increasing in the Chassahowitzka system,
but mean nitrate concentrations were lowest in the Chassahowitzka Spring Complex. Concerns about high bacteria levels in the Chassahowitzka River prompted the SWFWMD to perform remedial sampling of the headwaters and canals during the fall of 1997. Total and fecal coliforms were found to exceed state standards. A more detailed analysis, begun in October 1999, revealed that septic tanks are adversely infl uencing the water quality of the Chassahowitzka River. Fertilizing of golf courses, residential turf, and landscapes is also a signifi cant source of nutrients. Figure 3.5 , a composite map of the planning unit, shows waters on the 1998 303(d) list and the Verifi ed List. Table 3.7 summarizes the water quality assessment status of all waterbody segments in the planning unit.
The table and fi gure show that two waterbody segments in the planning unit are impaired. The two impaired segments in the planning unit, and the parameters of impairment, are as follows:

### Point Sources: Figure 3.5 shows permitted wastewater treatment facilities, landfi lls, and delineated ground water contamination areas in the planning unit. Appendix F lists the basin’s domestic and industrial surface discharge facilities, along with their permitted fl ows, by planning unit. It
also lists landfi lls or solid waste facilities, by planning unit.The Chassahowitzka River Planning Unit contains 9 permitted domestic and industrial facilities. One of them discharges greater than 0.1 mgd through surface water discharges or by land application of the effl uent. Nonpoint Sources: Based on Levels I and II land use summary information, the predominant land use in the planning unit is upland forests (approximately 40 percent of the planning unit’s area). Other major land uses include wetlands (22 percent) and urban and built-up (21 percent). These land uses can be associated with nonpoint discharges of pollutants
and eroded sediments. Appendix G provides summary information on Level I land uses in the basin, by planning unit.

### Ecological Summary

### Floating plants, cattails, and hydrilla are problems in the Chassahowitzka River.

• Middle Coastal Planning Unit

General Description 

### The Middle Coastal Planning Unit covers about 466 square miles and contains 53 segments with WBIDs (Figure 3.6)

. The Weeki Wachee River is located in southwest Hernando County,about 12 miles southwest of Brooksville. Weeki Wachee Springs, the headwaters of the river and the largest of 9 springs associated with the Weeki Wachee system, lies just southwest of the junction of U.S. Highway 19 and State Highway 50. The springs discharge an average of 176 cubic feet per second. From its headwaters, the Weeki Wachee River extends westward through approximately 7.5 miles of coastal swamps and marshes to the Gulf of Mexico. The Department designated the Weeki Wachee River as

an OFW. Tributaries to the river include the Mud River and Jenkin’s Creek. The Mud River joins the Weeki Wachee about 0.8 miles upstream of the mouth of the river. The headwaters of Jenkin’s Creek are located east of County Road 595. The creek fl ows west-northwest approximately 1.3 miles through a coastal marsh before reaching the Gulf of Mexico less than a quarter-mile south of the mouth of the Weeki Wachee River. Hammock Creek originates in several small springs clustered in a one-square-mile area in southwestern Hernando County. It is joined by several lesser tidal creeks before reaching the Gulf of Mexico at the town of Aripeka. The Pithlachascotee (Cotee) River system, located in western Pasco County, includes both estuarine and freshwater reaches. The river extends approximately 25 miles in a southwest direction, from its headwaters at Crews Lake to the Gulf of Mexico at Port Richey.Crews Lake, which covers approximately 693 acres, is directly connected to the Floridan aquifer by a sinkhole in the northern part of the lake. The lake level varies seasonally, and the lake may drain completely through the sinkhole during very dry years.

Water Quality Summary 

### Except for Weeki Wachee Springs, most of the springs in the Weeki Wachee area have very limited fl ow and water quality data. Changes in land uses in the watershed of the springs appear to have affected the coastal springs, rivers and creeks, and estuary. Although overall water quality in the river is still good, nitrate concentrations at the headspring have increased over time. In 1997, the mean nitrate concentration of the Weeki Wachee main spring was 0.53 milligrams per liter (mg/L) (for data collected from 1992 to 1996), 50 times higher than background levels (< 0.01 mg/L). Water quality in the Hammock Creek system is relatively good, except for rising nitrate concentrations. This system experiences less infl ows of

### fresh water than other river systems in the area, but remains an important part of the marine/estuarine ecosystem. Crews Lake exhibited good water quality historically. The upper portions of the Pithlachascotee River are surrounded by primarily rural land uses, while the lower reaches are relatively urbanized, especially around Port Richey and New Port Richey. This reach of the river receives signifi cant amounts of stormwater runoff. As a result, nitrogen and phosphorus levels, as well as bacteria and protozoans, have increased.Fertilizers on golf courses, residential turf, and landscapes are the predominant source of nutrients in the Weeki Wachee and Hammock Creek systems in the planning unit. Septic tanks are also a signifi cant source. Figure 3.6 , a composite map of the planning unit, shows waters on the 1998 303(d) list and the Verifi ed List. Table 3.8 summarizes the water quality assessment status of all waterbody segments in the planning unit.
The table and fi gure show that nine waterbody segments in the planning unit are impaired. The nine impaired segments in the planning unit, and the parameters of impairment, are as follows:

Permitted Discharges and Land Uses 

### Point Sources: Figure 3.6 shows permitted wastewater treatment facilities, landfi lls, and delineated ground water contamination areas in the planning unit. Appendix F lists the basin’s domestic and industrial surface discharge facilities, along with their permitted fl ows by planning unit. It
also lists landfi lls or solid waste facilities, by planning unit. The Middle Coastal Planning Unit contains 71 permitted domestic and industrial facilities. Twenty-six of them discharge greater than 0.1 mgd through surface water discharges or by land application of
the effl uent. There are no hazardous waste cleanup sites in the planning unit. The planning unit contains: two closed and monitored Class I solid
waste landfi lls; fi ve Class II solid waste landfi lls—one is inactive and four are closed and monitored; two Class III solid waste landfi lls—one is activeand the other is closed and monitored; and seven construction and demolition debris landfi lls—three are active and four are closed and monitored. Nonpoint Sources: Based on Levels I and II land use summary information, the predominant land use in the planning unit is urban and built-up (approximately 33 percent of the planning unit’s area). Other major land uses include upland forests (25 percent) and wetlands (22 percent). These land uses can be associated with nonpoint discharges

### of pollutants and eroded sediments. Appendix G provides summary information on Level I land uses in the basin, by planning unit.

Ecological Summary 

### Floating plants, cattails, and hydrilla are causing problems in the
Weeki Wachee River. Some wetlands in the planning unit, such as the Jay B. Starkey Wilderness Park in Pasco County, have dried up as a result of ground water pumping from wellfi elds. In the early to mid-1980s, the SWFWMD documented a shift from wetland to upland vegetation in the far western portion of the planning unit, where the most pumping occurred before 1983.

• Anclote River/Coastal Pinellas County Planning Unit

General Description 

### The Anclote River/Coastal Pinellas County Planning Unit covers about 252 square miles and contains 91 segments with WBIDs (Figure 3.7)

. The Anclote River, which originates in a swampy, low-lying area of south-central Pasco County, fl ows through the northwestern corner of Pinellas County and enters the Gulf of Mexico just north of Tarpon Springs. The principal tributaries to the river are Cross Cypress Branch,Sandy Branch, and South Branch. Near the coast are Salt Bayou, Whitcomb Bayou, and Kraemer Bay. From its headwaters to the middle reaches, the river fl ows through pine fl atwoods, citrus, pasture, and forested wetlands. In most years, the upper portion of the river dries up periodically. The lower portion of the river is a tidal estuary that fl ows into Anclote Anchorage, a shallow area of seagrass beds to the east of Anclote Key. The lower stretches of the river
fl ow through swampy tidally infl uenced lowlands, and tidal infl uences extend as much as 14 miles upstream. The mean depth of the lower river is just over 3 feet, except for a dredged shipping channel about 15 feet deep that extends from Tarpon Springs to the river mouth. Salinity at the river mouth ranges from 0.8 to 32.7 parts per thousand, depending on rainfall
and tidal fl ows. About 45 miles of barrier islands parallel the coast from the Anclote River to the mouth of Tampa Bay. Major land uses in the coastal region include residential and commercial development, citrus, and agriculture. From the Anclote River south to Sunderland Bayou, coastal communities such as mangroves and marshes predominate. Along the remainder of the coastline, however, the natural shoreline has been replaced with seawalls,
fi lled beaches, and riprap. The Boca Ciega Bay watershed comprises mostly urban land uses (83 percent). Boca Ciega Bay, the southernmost estuary in the basin, has been extensively modifi ed both physically and hydraulically. The bay, which covers about 181 square miles, has a mean depth of less than 7 feet. About 20 percent of its surface area was fi lled between 1950 and 1965. In addition, 5 major causeways cross the bay.

# 82 Water Quality Assessment Report: Springs Coast

### Lake Seminole, the second largest lake in Pinellas County, was created in 1950 by damming the upper portion of Long Bayou. Currently, almost 80 percent of the lake’s drainage area is urban. The lake was isolated by a water control structure built in the 1940s and now discharges over a weir to Long Bayou, which fl ows to Boca Ciega Bay.

Water Quality Summary 

### In the upper stretches of the Anclote River, low DO levels are common
because of low fl ows and the presence of decomposing organic materials (leaves). Most of the land use in this area is agricultural, and the major water quality concerns are bacteria and nutrients. Salinity levels vary in the lower portions of the river because of tidal infl uences, and elevated levels of phosphorus occur periodically as a result of agricultural runoff. At Tarpon Springs, the river receives urban runoff and point source discharges. Tidal
fl ows, rainfall, and runoff infl uence water quality in Anclote Anchorage. Urban land uses in the Anclote River watershed are expected to increase by over 270 percent by the year 2010, with corresponding losses to agriculture and upland forest of 98 and 71 percent, respectively. Water quality in estuarine areas south of Anclote Anchorage depends
on tidal fl ushing and the number of localized discharges from point and nonpoint sources. Curlew Creek has high levels of total phosphorus (TP), ammonia, total Kjeldahl nitrogen, and total and fecal coliforms. In St. Joseph Sound, north-to-south increases in color and chlorophyll a levels correspond with increased urbanization and point source discharges.In the Clearwater Harbor watershed, land use mostly consists of highdensity residential development. Clearwater Harbor receives signifi cant amounts of drainage from creeks, channelized ditches and streams, storm sewers, and sheet flow. Water quality in the harbor is generally good; however, some tributaries and areas in the watershed have poor water quality, including Curlew Creek (high concentrations of nitrates and chlorophyll a ) and Klosterman Bayou/Innisbrook Canal and Stevenson Creek (nitrogen, TP, TSS, and chlorophyll a ). The Klosterman Bayou/Innisbrook Canal sampling station located at U.S. 19 was ranked worst among the sites in Clearwater Harbor sampled by Pinellas County. The Narrows has poor water quality, with high levels of ammonia, TP, orthophosphate, and total Kjeldahl nitrogen from surface runoff and urban

stormwater systems. Water quality in Boca Ciega Bay is affected by proximity to the tributary mouths, barrier island passes, and seasonal patterns of water movement. A number of tributaries to the bay have been converted to underground storm sewers or open ditches, and generally, the quality of urban stormwater draining to the bay is poor. In some areas, there may also be sediment contamination. In particular, Cross Bayou, Long Bayou, Joe’s Creek, and Cross Bayou Canal are close to contaminated discharges,
and fl ushing is restricted. These waterbodies have the worst water qualityin the Boca Ciega Bay system, with low DO levels and high levels of nutrients, BOD, and coliform bacteria. Stormwater from Bear Creek, a residential drainage basin, contains elevated levels of total and fecal coliforms, lead, and zinc, as well as the 

# 83 Water Quality Assessment Report: Springs Coast

### pesticides chlordane, Silvex, 2,4-D, and 2,4,5-T. Sediment samples from the creek contain high levels of volatile solids, total nitrogen, TP, and lead,in addition to chlordane, dichlorodiphenyldichloroethane, dieldrin, polychlorinated biphenyls, and heptachlor-epoxide. The upper reaches of Joe’s Creek consist of two-thirds storm sewer and one-third open ditch. Stormwater and sediment quality in the creek are similar to those of Bear Creek, except for higher concentrations of heavy metals, lead, and zinc. Lake Seminole, which has no tidal fl ushing, has had poor water quality for many years and is hypereutrophic. The lake has high concentrations of chlorophyll a and TSS. The blue-green alga Cylindrospermopsis sp. is the main contributor to the lake’s algal biomass. Figure 3.7 , a composite map of the planning unit, shows waters on the 1998 303(d) list and the Verifi ed List. Table 3.9 summarizes thewater quality assessment status of all waterbody segments in the planning unit.

Notes:

1 The designation “stream” includes canals, rivers, and sloughs. The designation “lake” includes some marshes.

2 The state’s surface water classifications are as follows: Class I: Potable water supplies Class II: Shellfish propagation or harvesting Class III: Recreation, propagation, and maintenance of a healthy, well-balanced population of fish and wildlife Class IV: Agricultural water supplies Class V: Navigation, utility, and industrial use (there are no state waters currently in this class)

3 The EPA’s 305(b)/303(d) Integrated Report categories are as follows: 1 —Attains all designated uses; 2 —Attains some designated uses; 3a —No data and information are available to determine if any designated use is attained; 3b —Some data and information are available, but they are insufficient for determining if any designated use is attained; 3c —Meets Planning List criteria and is potentially impaired for one or more designated uses; 3d —Meets Verified List criteria and is potentially impaired for one or more designated uses; 4a —Impaired for one or more designated uses and the TMDL is complete; 4b —Impaired for one or more designated uses, but no TMDL is required because an existing or proposed pollutant control mechanism provides reasonable assurance that the water will attain standards in the future; 4c —Impaired for one or more designated uses but no TMDL is required because the impairment is not caused by a pollutant; and 5 —Water quality standards are not attained and a TMDL is required.

4 The assessment categories listed in this column represent the status of each WBID as a whole, based on multiple parameters

. The hierarchy of assigning these categories is Category 5, then 4, then 3c, then 2, and then 3b, i.e., each WBID is assigned a category based on the highest category assigned to an individual parameter. For example, if WBID 9999 has one parameter as a Category 5, then this supersedes parameters at Category 3c or 2, and the WBID as a whole is classed as a Category 5.

Permitted Discharges and Land Uses 

### Point Sources: Figure 3.7 shows permitted wastewater treatment facilities, landfi lls, and delineated ground water contamination areas in the planning unit. Appendix F lists the basin’s domestic and industrial surface discharge facilities, along with their permitted fl ows, by planning unit. It
also lists landfi lls or solid waste facilities, by planning unit. The Anclote River/Coastal Pinellas County Planning Unit contains 76 permitted domestic and industrial facilities. Twenty-eight of them discharge greater than 0.1 mgd through surface water discharges or by land application of the effl uent. There is one hazardous waste cleanup site in the planning unit. The planning unit contains one closed and monitored Class I solid
waste landfi ll; two closed and monitored Class III solid waste landfi lls; and
one closed and monitored construction and demolition debris landfi ll. Nonpoint Sources: Based on Levels I and II land use summary information, the predominant land use in the planning unit is urban and built-up (approximately 57 percent of the planning unit’s area). Other major land uses include wetlands (14 percent) and agriculture (12 percent). These land uses can be associated with nonpoint discharges of pollutants
and eroded sediments. Appendix G provides summary information on Level I land uses in the basin, by planning unit.

Ecological Summary 

### Invasive Exotic Species. In a number of areas in the Anclote River watershed, agricultural and urban development have provided pathways for invasive exotic species such as cogon grass (Imperata cylindrica) ; Brazilian pepper (Schinus terebinthifolius) ; air potato (Dioscorea bulbifera) ; skunk

vine (Paederia foetida) ; melaleuca (Melaleuca quinquenervia) , which is also
called cajeput, or punk tree; and tropical soda apple (Solanum viarum)

. Portions of the SWFWMD’s Starkey wellfi eld property (about 8,000 acres) and the privately owned Anclote River Ranch (about 4,000 acres) have 

# 94 Water Quality Assessment Report: Springs Coast

### problems with invasive exotics, as do urban areas near the mouth of the
Anclote River. In the western Pinellas peninsula, Brazilian pepper and Australian pine (Casuarina equisetifolia) are found along roadways and in disturbed coastal habitats (i.e., dredged and fi lled areas and residential areas). Pockets of Australian pine planted in the 1940s and 1950s can be found along several portions of the Intracoastal Waterway and the Gulf beaches. Infestations of hydrilla (Hydrilla verticillata) have been found in the Anclote River, Allens and Stevenson Creeks in the city of Clearwater, drainage canals and retention ponds in the city of Dunedin, and Lake Seminole. Other invasive species in the watershed include melaleuca and water hyacinth (Eichhornia crassipes)

. Forest Fragmentation. Extensive land clearing for farming and cattle operations has resulted in the destruction and degradation of a number of ecosystem types in the Anclote River watershed, including pine fl atwoods,xeric habitats, and riparian and other wetland ecosystems. Urban development pressures are substantial near the mouth of the Anclote River and the southern boundary of the Anclote River watershed. The largest areas of remaining natural habitat include the SWFWMD’s Starkey wellfield property (about 8,000 acres), the Serenova tract (about 10,000 acres), and the privately owned Anclote River Ranch (about 4,000 acres). Ground water pumping at the Starkey wellfi eld has degraded wetland habitats both inside
and outside the wellfi eld’s boundaries. Habitat destruction and fragmentation in western Pinellas County have also been severe. Dredging and fi lling along the coast and on the barrier islands have destroyed tidal marsh and tidal swamp habitats, while inland development has eliminated most areas of pine fl atwoods, depressionmarsh, and xeric habitat. The remaining natural habitats are highly fragmented and subject to urban impacts. Some of the largest publicly owned lands include Caladesi and Honeymoon Islands, as well as lands owned by Pinellas County adjacent to Boca Ciega Bay (about 200 acres). Habitat improvement efforts in the watershed should focus on restoring coastal wetland and upland habitats.
Habitat Balance. About 1.9 percent of Pinellas County consists of conservation lands; Pasco County ranks higher, with 10.4 percent of its lands in conservation. Pinellas County is currently attempting to acquire land along the Anclote River corridor to provide a connection to the Brooker Creek Preserve, and possibly the Starkey Preservation Area in Pasco County. Critical issues in the Anclote River watershed include maintaining
buffers and fl oodwater storage areas, as well as stream basefl ow. In westernPinellas County, major issues include protecting mangrove habitat; reducing motorized boat traffi c to protect nearshore and inshore areas from wake-generated wave damage, propeller dredging, and damage to seagrassfrom boat propellers; altering shoreline protection devices; restoring seagrasses and dredge holes in the bay bottom; and establishing (or reestablishing) tidal connections to increase water exchange.
Protection of Wildlife Corridors. Significant areas of wildlife habitat remain in the Anclote River watershed, and the potential for wildlife 

# 95 Water Quality Assessment Report: Springs Coast

### corridors is signifi cant. Riparian habitat and associated uplands along the middle and upper reaches of the Anclote River, as well as Cross Cypress Branch and Sandy Branch to the north and south, respectively, provide excellent linkages between areas of core habitat. Much of this riparian habitat is within the SWFWMD’s Starkey property (about 8,000 acres) and Serenova tract (about 10,000 acres). In western Pinellas County, there are few remaining areas of core habitat and, therefore, little corridor potential. Lands adjacent to and near Long Bayou and Lake Seminole provide the best opportunity to protect
wildlife corridor habitat.
Identifi cation and Protection of Estuarine Aquatic Ecosystems. The Anclote River watershed is still relatively undeveloped, except for the extreme western portion near Lake Tarpon and the Gulf of Mexico. Expanding residential growth into southern Pasco County, however, couldjeopardize water quality in the Anclote River. A decline in water quality could damage seagrass beds located south and west of the mouth of
the river. Western Pinellas County, which is highly urbanized, directly influences water quality in lower Tampa Bay, Boca Ciega Bay, Long Bayou, and Clearwater Harbor. Between 1988 and 1994, seagrass coverage in Boca Ciega Bay increased by 17 percent. Future restoration projects should focus on both stormwater treatment and habitat restoration. Completed SWIM restoration projects include Joe’s Creek and Boca Ciega Phase I. Future projects include Cross Bayou/Joe’s Creek and Boca Ciega Phase II. Water quality and seagrass coverage in Clearwater Harbor and the estuarine coastal areas north of Clearwater should be monitored regularly in order to assess the health of these systems. Nonpoint Source Loading. Historically, agricultural land uses were the major contributors to nonpoint source pollution in the Anclote River watershed. Recently, as the population has grown in southern Pasco and northern Pinellas County, urban and suburban runoff have become a signifi cant issue. Small creeks and tributaries that empty into the Anclote River, as well as the Anclote River itself, receive stormwater runoff from all of these sources. The SWFWMD has purchased thousands of acres of natural habitat in the watershed, which should help to maintain surface water quality in the middle and upper reaches of the Anclote River and its
tributaries.In western Pinellas County, stormwater runoff from urban and suburban development affects water quality in several estuarine areas, including Clearwater Harbor, Long Bayou, and Boca Ciega Bay. Several current and planned SWIM habitat restoration and stormwater improvement projects should help fi lter runoff before it enters these sensitive areas.

# Chapter 4: Evaluation of Ground Water and Geologic Influences on Impaired Waterbodies

This chapter evaluates the potential infl uences of ground water and the natural geologic, soil, and/or ground water chemistry on surface water quality in the Springs Coast Basin. In particular, it focuses on surface waters on the Planning or Verifi ed Lists. The chapter contains a general and by-planning-unit discussion and presentation of information. It also includes recommendations for an alternative listing status for waterbodies that exceed Impaired Surface Waters Rule listing thresholds due to natural conditions. The listing parameters receiving scrutiny include nutrients (nitrate+nitrite, ammonia, orthophosphate) and dissolved oxygen (DO).



## Geology, Soil, and Ground Water

Ground Water and SpringsGround water recharge in the Springs Coast Basin takes place pred ominantly along the Brooksville Ridge and, to a lesser degree, in the Gulf Coastal Plain. Some recharge also occurs in the Tsala Apopka Plain. Regional ground water fl ow moves generally from east to west, from the Tsala Apopka Plain and the Brooksville Ridge westward to springs discharging in Citrus, Hernando, and Pasco Counties, at the boundary between the Coastal Swamps and the Gulf Coastal Plain. This dischargeboundary lies just west of U.S. 19 within these counties and nearly coincides with the freshwater-saltwater transition zone. As discussed in Chapter 2, the Springs Coast Basin contains 4 major spring complexes and numerous smaller springs, which occur as a result of the region’s karst geology. Combined, these 4 complexes discharge approximately 900 million gallons per day (mgd) from the Floridan aquifer system. Rainfall, the primary recharge mechanism for the aquifer, averages 56 inches per year in the basin. Spring flow is the major discharge mechanism for the aquifer, accounting for 64 to 84 percent of the total recharge input. The Crystal River/ Kings Bay Springs Complex, the largest such complex in the basin, discharges approximately 630 mgd. The three other major springs—Weeki Wachee, Chassahowitzka, and Homosassa—discharge on average 113, 90, and 68 mgd, respectively. Other large springs in the basin include Ruth Spring, Salt Spring, Little Springs, Bobhill Springs, Magnolia Springs, Horseshoe Spring, Salt Springs, Wall Springs, Crystal Beach Submarine Spring (which is located about 1,000 feet offshore), and Tarpon Springs (which is tidally infl uenced and can reverse fl ow). 

# 97 Water Quality Assessment Report: Springs Coast

### In Pinellas County, the Coastal Swamps give way to barrier island complexes. Still, several smaller springs are present in the northern portion of the county. Due to a smaller upland recharge area and thickening coastal sediment cover, springs are absent within the confi nes of the Springs

Nutrients Nutrients in low concentrations, such as the various nitrogen species (n itrate, nitrite, nitrogen, ammonia) and phosphorus (usually as orthophosphate), are naturally occurring constituents of Floridan aquifer system ground water at low concentrations. Historical median background levels of nitrate+nitrite in the Floridan aquifer system are believed to both be on the order of 0.01 milligrams per liter (mg/L). (These nitrate+nitrite levels are measured as N and often collectively referred to as nitrate , because nitrate always predominates over nitrite in concentration.) Orthophosphate concentrations, also naturally low and on the same order as nitrate, can be higher in noncarbonate aquifers, such as the surfi cial aquifer system.Nutrients, in particular the various nitrogen species, are the predominant analytes of concern for potential ground water contamination of surface waterbodies in the basin. Nitrogen occurs naturally in both organic and inorganic forms, but elevated detections of inorganic nitrogen in ground water are typically associated with pollutant sources. Isotopic studies of nitrate in the Homosassa, Chassahowitzka, Weeki Wachee, and Aripeka Spring Complexes have determined that the nitrate in ground water is from primarily inorganic sources (Jones, Upchurch, Champion,and DeWitt, 1997). Inorganic nitrogen is typically associated with fertilizer that is applied in agricultural areas, on turf, and on residential lawns. Nutrients, especially nitrate, are the pollutants of greatest concern in ground water discharge to surface waters in the basin. Changing land uses in the ground water recharge areas of the basin since the 1970s coincide with a dramatic increase in nitrate concentrations, while phosphorus levelshave remained relatively steady. This is because nitrate is relatively nonreactive within the Floridan aquifer system, while orthophosphate is reactive. Most nitrogen species introduced into the aquifer convert to the nitrateanion (NO3-) and pass through from source to discharge point, with concentrations only signifi cantly diminished by dilution from aquifer waters containing lower nitrate concentrations. For orthophosphate, however, the geochemistry of the Floridan aquifer system’s carbonate matrix favors the reaction between ground water orthophosphate (PO4-3) and calcite (CaCO3), the predominant mineral in limestone. This reaction forms phosphorite, a rock composed predominantly of carbonate-hydroxylapatite (Ca5[OH,O|(PO4,CO3)3]). Orthophosphate levels can be higher in noncarbonate aquifers, such
as the surficial aquifer system, depending on the chemical composition of the aquifer material. The Hawthorn Group, which serves as an

### upper confi ning unit for the Floridan aquifer, includes natural deposits of phosphate and is a source of phosphorus in some ground waters.
Elevated nutrient levels in surface waters can cause excessive chlorophyll growth (measured as high chlorophyll a levels in streams and estuaries) and high Trophic State Index (TSI) values (measured in lakes). Another adverse effect of elevated nutrients is the excessive growth of algae and invasive plants, which can result in ecological imbalances in spring-run systems and their receiving waters. These types of ecological imbalances constitute the predominant impacts to the majority of springs in Florida,including those in the Springs Coast Basin, and can be the result of relatively small increases in nitrate or phosphorus. Recent research by Stevenson, Pinowska, Albertin, and Sickman (2007) suggests that reductions in total nitrogen to levels substantially below 0.25 mg/L and total phosphorus to levels below 0.026 mg/L are needed to signifi cantly reduce the extent of spring bottom cover of the algal species Vaucheria sp. and Lyngbya wollei. (Most total phosphorus levels in ground water and basin springs are already below that value.) It is thought that nitrogen was the predevelopment limiting nutrient in high ground water-sourced surface waters, but that due to the recent increases in nitrate concentrations in ground water, phosphorus has become the limiting nutrient, much of it entrained in and recycled from geologic material and
stream-bottom sediments.

Dissolved OxygenLow DO levels are characteristic of ground waters with long underg round residence times (such as most Floridan aquifer system waters). Ground water-sourced rivers, such as the spring-fed coastal rivers in the Springs Coast Basin, show initially low DO values when measured at the head springs. In these rivers, which have substantial submerged aquatic vegetation in their upper reaches, low DO values can rebound to normal levels within a relatively short distance downstream from the head spring, because plant photosynthesis releases DO into the water column. Spring runs with little submerged aquatic vegetation have lower DO values that can negatively affect the diversity and abundance of fi sh and invertebrate species. DO levels can also be depressed in surface water systems because of nutrient enrichment and/or biochemical oxygen demand (BOD). In addition, low DO can be attributed to poor water circulation caused by stream channelization or disruption in fl ow.



## Evaluations by Planning Unit

This section summarizes, for each planning unit, ground water chemical characteristics that may be related to impaired waterbodies on the
Verifi ed List, evaluates ground water fl ow, reviews pertinent geologic and soil information, and evaluates land use and anthropogenic sources. The discussion focuses on ground water sources affecting surface waters and isthus oriented more toward major spring discharge locations in each planning unit and their associated springsheds, in deference to planning unit
boundaries.

### Overview of Ground Water and Spring Water Quality
Tables 4.1 an d 4.2 present water quality statistics from wells and springs for all of the basin’s planning units. The data were obtained from the Department’s Oracle-based Ground Water Information System (OGWIS) and from the Southwest Florida Water Management District (SWFWMD) Water Quality Monitoring Program. Data retrieved from
OGWIS were for the Floridan and surfi cial aquifer systems and springs. SWFWMD data were obtained for the upper Floridan aquifer and springs.

### Median ground water values for 3 of the 5 planning units indicate that nitrate+nitrite (dissolved, measured as N) in ground water was elevated compared with historical background levels for both the surfi cial and Floridan aquifer systems, but was well below the Florida primary ground water standard of 10 mg/L. Median values for nitrate+nitrite from springs were highest in the Anclote River Planning Unit, at 6.0 mg/L (data from 5 springs), and lowest in the Crystal River/Kings Bay Planning Unit at 0.2 mg/L (data from 23 springs). Ammonia (dissolved, measured as N) values from Floridan aquifer system wells and springs are typically very low, except in cases where very localized sources are present. These sources are usually organic and include concentrated animal-feeding operations or malfunctioning septic or sewage systems. Ammonia typically converts to nitrate before it reaches the aquifer. Orthophosphate (dissolved, measured as P) ground water values for
all five planning units are at or near historical background concentrations, except for surfi cial aquifer system values in the Middle Coastal Planning Unit; however, this was based on samples from only two wells. Springs values were also near historical background concentrations, except for a median value of 0.07 mg/L from two springs in the Anclote River Planning Unit.
DO values from both surfi cial and Floridan aquifer system wells were suboptimal by surface water standards but relatively normal for ground water, with surfi cial values generally higher than Floridan values, as expected, because ground water residence times in the surfi cial are generally
shorter than in the Floridan. Figures 4.1 and 4.2 depict the value ranges and sample locations for nitrate+nitrite and orthophosphate, respectively, for springs and wells in the Springs Coast Basin. Also shown are the locations of major springsheds for the larger Springs Coast spring groups. Springsheds are ground water capture areas that contribute water to springs, like a surface watershed. Note that springshed boundaries include large recharge areas that extend beyond the Springs Coast Basin, which was defi ned using surface water
basins. The fi gures clearly show that ground water from recharge areas along the Brooksville Ridge outside the Springs Coast Basin (and Tsala Apopka Lake for the Kings Bay and Homosassa springsheds), but within the adjacent Withlacoochee Basin, fl ows west to discharge at points along the Springs Coast.

Crystal River/Kings Bay Planning Unit While no surface waters in the planning unit are currently listed as

i mpaired for nutrients or DO, there are serious ecological imbalances in Kings Bay and Crystal River associated with nutrients from springs. The Kings Bay Springs Group is the second largest spring system in Florida by volume of water discharged and includes 30 known springs (Champion,2001). The springshed for this group is expansive, including the eastern half of the Crystal River/Kings Bay Planning Unit, the northeastern half of the adjacent Homosassa River Planning Unit, and a large region

Withlacoochee Basin. The median nitrate+nitrite value from 51 Floridan aquifer system wellsin the planning unit was 0.10 mg/L, higher than historical statewide background concentrations of about 0.01 mg/L. Historical water quality datafrom Kings Bay springs are few, but they do show that nitrate concentrations in the early 1900s were 20 times lower than they are now (Upchurch, 1992). Table 4.2 indicates that the median value for nitrate+nitrite for 23 spring stations in the Crystal River Planning Unit is 0.20 mg/L, elevated compared with background but lower than spring median values in any of the other Springs Coast Basin planning units. Hunter Spring, one of the major springs in the group, has nitrate at concentrations signifi

- cantly higher than this median. Figure 4.3 shows recent nutrient concentrations in Hunter Spring and the other major spring in this group, Tarpon Hole (both sampled quarterly since October 2001 by the Department’s Florida Springs Initiative). Over this period, nitrate+nitrite values are elevated, but no major trends arediscernible. Prior to this time, a slight upward trend in nitrate concentrations (increasing from around 0.25 to 0.35 mg/L from 1991 to 1998) had been measured at Hunter Spring (Jones, Upchurch, and Champion, 1998). The results from this study for Tarpon Hole Spring are similar to those
shown in Figure 4.3 , indicating that no signifi cant increases in nitrate

### have occurred since 1991 and that the average concentrations are much lower than those from Hunter Spring. The dissimilarity between nitrate trends and concentrations for Hunter Spring and Tarpon Hole Spring is an example of how different sources can affect individual springs in the Kings Bay springshed. Also shown in Figure 4.3 are the relatively low orthophosphate concentrations, which display no trends and are similar to most major springs in the state. Several researchers have noted the increasing occurrence of Hydrilla sp. and the alga Lyngbya wollei , along with a decline in native submerged aquatic vegetative species. In a SWFWMD study of these invasive species, Romie (1990) determined that ground water discharge from springs was responsible for 94 percent of the total nitrogen and 84 percent of the total phosphorus entering Kings Bay. Other sources noted in this study included stormwater runoff, septic tank leachate, package plant effl uent, and the city of Crystal River’s sewage treatment plant discharge into Cedar Cove (partof Kings Bay). The Crystal River sewage treatment plant ceased discharging treated effl uent into Cedar Cove in 1992 (SWFWMD, 2004). Tidal
fl uctuations also affect loading, particularly from springs whose fl ow is affected by the interrelationship between sea level and aquifer head. A SWFWMD study of the Kings Bay springshed by Jones, Upchurch, and Champion (1998) stated that low sulfate concentrations and isotopic data indicate a shallow ground water fl ow regime in the Floridan aquifer system, and that waters discharging from area springs generally come fromaquifer recharge that occurred during the last 50 years. The study indicated that the widespread use of inorganic fertilizers on residential lawns and golf courses was principally responsible for nitrate to ground water, and that nitrate contributions may increase along with development in the Crystal River area and outlying springshed. Ground water enriched in nitrate from development-related and natural sources was noted in
well- defi ned plumes from northern and east-central Citrus County; these plumes were predicted to reach the Kings Bay Springs Group by about 2010, causing an increase in nitrate discharging from these springs. Data specifi cally indicated anomalously high local recharge in Beverly Hills, a highly developed residential area atop the Brooksville Ridge within the springshed, approximately 8 miles east-northeast of Kings Bay. Ammonia in ground water is low (a median value of 0.08 mg/L from 5 Floridan aquifer system wells) in ground water of the Kings Bay springshed. A median value of 0.01 mg/L from 11 sampled springs refl ects background conditions for this analyte. DO values from 5 Floridan aquifer system wells in the planning unit had a median value of 0.43 mg/L, low for surface waterbodies but within the normal range for Floridan ground water. DO was not identifi ed as an impairment for springs and spring-dominated streams in the planning unit because of the ground water contribution.

Homosassa River Planning Unit No surface waters in the planning unit are currently listed as impaired

### from springs. The springshed for the Homosassa Springs Group encompasses the south-central portion of the Homosassa River Planning Unit, the northeastern half of the adjacent Chassahowitzka Planning Unit, anda large region east of these planning units that extends into the Withlacoochee Basin. The median nitrate+nitrite value from 25 Floridan aquifer system wells in the planning unit was 0.22 mg/L, somewhat higher than background. Historical water quality data from the Homosassa Springs Group are limited: nitrate concentrations in 1946 and 1956 were 0.2 and 0.13 mg/L, respectively, and were at a similar level in the 1970s (ranging from 0.2 to 0.3 mg/L). In the latter half of the 1990s, nitrate concentrations in the Homosassa Springs Group had risen to approximately 0.4 to 0.5 mg/L. By 2001, they were in the 0.5 to 0.6 mg/L range, a signifi cant increase since the 1970s. For the 30 spring stations in the planning unit, the median nitrate concentration is 0.45 mg/L (Table 4.2)

. Figure 4.4 shows recent nutrient concentrations in the three springs that make up the source of the Homosassa River. The similarity in nitrate trends and concentrations indicates that all three vents respond in a similar manner for this analyte and that all three likely receive signifi cant recharge from the larger springshed, which includes portions of the BrooksvilleRidge and Lake Tsala Apopka in the Withlacoochee Basin. Other analytes sampled from these vents, however, show differences in water quality,

### indicating potentially different local recharge sources (Champion and Starks, 2001). The SWFWMD springs study that included Homosassa (Jones,Upchurch, Champion, and DeWitt, 1997) stated that low sulfate concentrations and isotopic data indicate a short, shallow ground water fl ow regime in the Floridan aquifer system, and that water discharging from thesprings is generally less than 50 years old. The study investigated 14 potential nitrate sources in the springshed and concluded that residential and golf course turf/landscape fertilization were the principal sources of nitrate in Homosassa and other spring complexes to the south. The conclusions werebased on the following: (1) the inorganic nature of the sources, as determined from nitrogen isotopic analyses; (2) the close proximity of sources to springs; and (3) the rapid increase in nitrate concentrations in the springs that began in the late 1960s, correlating with the development of the large,coastal residential subdivisions that contain the largest densities of residential and golf course turf and landscape. The ammonia median value of 0.02 mg/L from 3 Floridan aquifer system wells in the planning unit and the median value of 0.01 mg/L from 10 springs in the planning unit are very low and refl ect background
conditions. Orthophosphate in ground water is somewhat elevated (median of 0.21 mg/L for 26 wells) compared with data from spring stations in the planning unit (median of 0.02 mg/L in 27 spring stations (Table 4.2)

.The ground water value is somewhat higher than the statewide background concentration for Floridan aquifer system ground water and may
refl ect infl uence by phosphatic material in the overlying Hawthorn Group. The spring data also match well with data shown in Figure 4.4 , which depicts similar concentrations and no trends from the 3 main Homosassa Spring vents.The DO median value for Floridan aquifer system wells in the planning unit was 0.62 mg/L, low for surface waterbodies but within the normal range for Floridan aquifer system ground water. Springs were not listed as impaired by low DO for this reason.

Chassahowitzka Planning Unit No surface waters in the planning unit are currently listed as impaired
b y nutrients or DO; however, similar nutrient-related ecological imbalances that were present in the other Springs Coast spring systems are present in the Chassahowitzka system. The springshed for the ChassahowitzkaSprings Group roughly encompasses the southern half of the Chassahowitzka Planning Unit, the northeastern portion of the adjacent Middle Coastal Planning Unit, and a region southeast of these planning units along the Brooksville Ridge, extending into the Withlacoochee Basin. The median nitrate+nitrite concentration for the 30 Floridan aquifer system wells in the planning unit was 0.28 mg/L. Nitrate+nitrite data from
1 surfi cial aquifer system well in the planning unit was also 0.28 mg/L. Historical water quality data from the Chassahowitzka Springs Group is limited; measurements collected in 1946 showed nitrate concentrations near 0.05 mg/L. Nitrate data collected in the 1970s showed an increase, 

# 107 Water Quality Assessment Report: Springs Coast

### generally within the 0.1 to 0.3 mg/L range. In the latter half of the 1990s, Chassahowitzka values had risen into the 0.4 to 0.5 mg/L range, and the trend since 2001 shows nitrate continuing to rise into the 0.6 mg/L range, a twelvefold increase since the mid-20th century and over 60 times more than historical statewide background Floridan aquifer concentrations(Champion and Starks, 2001). The median nitrate+nitrite concentration (from 36 spring stations) was 0.37 mg/L (Table 4.2)

. Figure 4.5 shows recent nutrient concentrations for the 2 main spring vents that are
the source for the Chassahowitzka River. Nitrate concentrations in these 2 springs are signifi cantly higher than the median for all springs in the group and provide the highest nitrate loads to the river. The SWFWMD study (Jones, Upchurch, Champion, and DeWitt, 1997) showed that water in the Chassahowitzka spring system is on average 50 years old or younger. The study also showed that residential and golf course turf/landscape fertilization were the principal sources of nitrate in Chassahowitzka and other spring complexes to the north and south. Another factor potentially affecting Chassahowitzka ground waterquality is the absence of Hawthorn Group clays overlying Tertiary limestones along the Brooksville Ridge from the city of Brooksville north to the vicinity of the Citrus–Hernando County line. This area, which lies within the Chassahowitzka springshed, is home to numerous limestone quarries excavated into the Suwannee Limestone, which covers many

### square miles. These quarries act as penetrating karst features, which, along with numerous natural karst features in the Brooksville urban area, increase potential recharge directly into the Floridan aquifer system from the region, without signifi cant attenuation by overlying soils. The ammonia median value of 0.04 mg/L from 4 Floridan aquifer system wells in the planning unit (at least 2 fall outside the Chassahowitzka springshed) and the median value of 0.01 mg/L from 13 spring stations in the planning unit are very low and refl ect background conditions. Orthophosphate values for 26 spring stations in the Chassahowitzka Planning Unit had a median concentration of 0.02 mg/L (Table 4.2) , and 31 Floridan aquifer system wells in the planning unit (at least 2 are located outside the Chassahowitzka springshed) had a median value of 0.028 mg/L.These values are slightly higher than the statewide background concentration for Floridan aquifer system ground water. This also matches well with
data shown in Figure 4.5 , which depicts similar concentrations and no trends from recent data collected from the 2 main Chassahowitzka Spring
vents. One surfi cial aquifer system well had an orthophosphate value of 0.058 mg/L.The DO median value for 4 Floridan aquifer system wells in the planning unit was 2.9 mg/L, somewhat elevated compared with other Floridan well samples in the basin. One surfi cial aquifer system well in the planning unit had a measured DO level of 4.97 mg/L.

Middle Coastal Planning Unit No surface waters in the planning unit are currently listed as impaired
b y nutrients or DO; however, similar nutrient-related ecological imbalances that were present in the other Springs Coast spring systems are present in the Weeki Wachee Springs and Aripeka Springs Group— particularly Weeki Wachee, which has the highest nitrate concentrations. The springsheds for Weeki Wachee Springs and the Aripeka Springs Group (Bob Hill, Boat, Magnolia, and Aripeka Springs Nos. 1 and 2) encompass approximately the central third of the Middle Coastal Planning Unit. Part of the Weeki Wachee springshed extends into the adjacent Withlacoochee and Tampa Bay Tributaries Basins along and east of the Brooksville Ridge. The median nitrate+nitrite concentration for 83 Floridan aquifer system wells in the planning unit is 0.13 mg/L, similar to the northern planning units in the basin. Historical water quality data for Weeki Wachee Springs are limited and practically nonexistent for the Aripeka Springs Group. Figure 4.6 shows existing nitrate data for Weeki Wachee Springs from 1946 through 1999, compared with population trends inHernando County for the same period. The median nitrate+nitrite concentration for 28 spring stations in the basin is 0.44 mg/L (Table 4.2) . Of these, Weeki Wachee Spring has the highest nitrate levels. More recent quarterly water quality data collected by the Department’s Florida Springs Initiative monitoring network indicate that nitrate+nitrite values in Weeki Wachee Spring have increased to a median concentration of over 0.8 mg/L, the highest of any major spring in the Springs Coast Basin. Because data from wells distributed throughout the planning unit show

### very low nitrate+nitrite concentrations, it is likely that nutrient sources in the springs’s immediate area contribute the bulk of the nitrate load. This is in agreement with conclusions reached by Jones, Upchurch, Champion, and DeWitt (1997). Their study concluded that, based on theabove data and also on nitrogen isotope data, inorganic sources—principally residential and golf course turf/landscape fertilization—were the principal sources of increasing nitrate. These data and conclusions correlate with the development of the large, coastal residential subdivisions adjacentto Weeki Wachee, which contain the highest density of residential development and the largest number of golf courses (Figure 4.7)

. The ammonia median value of 0.04 mg/L from 19 Floridan aquifer system wells in the planning unit and the median value of 0.01 mg/L from 11 springs in the planning unit are low and refl ect background conditions. The 27 spring stations in the Middle Coastal Planning Unit had a median orthophosphate concentration of 0.01 mg/L (Table 4.2) , which is essentially the same as background. Eighty-four Floridan aquifer system wells had a median orthophosphate value of 0.05 mg/L; these values are slightly higher than the statewide background concentration for Floridan aquifer system ground water. Two surfi cial aquifer system wells produced a Figure 4.6: Relationship between nitrate trends in Weeki Wachee Springs and population trends in Hernando County.

The largest ground water contribution to these waterbodies is likely from the surfi cial aquifer via seepage, rather than from the Floridan aquifer via springs. Unlike the planning units to the north, the Anclote River/Coastal Pinellas County Planning Unit has few known springs, and the ones present are of low magnitude—this includes Tarpon, Health, and

### Crystal Beach Submarine Springs. All of these springs are located in the northwest third of the planning unit. The subsurface geology of most of the planning unit differs from that
to the north. The northern coastal Pinellas and western Anclote River watersheds occupy an area where Tertiary limestones of the Floridan aquifer system (specifi cally, the Tampa Member of the Arcadia Formation) occur at or near the land surface. In addition to a few springs, this area is characterized by scattered karst depressions (sinkholes and sinkhole lakes) and subsurface conduits, one of which links Tarpon Spring to Tarpon Lake. South of Palm Harbor, the Tertiary limestones dip gradually to the west and southwest, beneath a thickening wedge of Quaternary to Recent
coastal sediments. Ground water discharges along the Pinellas County coastline tothe south are considerably lower than those to the north, and primarily represent surfi cial aquifer system seepage into area canals and inland water bodies. Land use patterns in most of the southern portion of the planning unit are almost completely dominated by urban, residential, and
commercial uses. Crystal Beach Submarine Spring, the southernmost signifi cant spring in the basin, discharges brackish water into the Intracoastal Waterway; the vent is located about 1,000 feet (300 meters) offshore from the community of Crystal Beach. The spring is fed from Floridan aquifer system water mixed with seawater, and the explored cave extends to the northeast of the vent under dry land (Garman, 1999). It contains an interesting mix of salt-tolerant troglobitic invertebrates and microorganisms and is somewhat representative of similar troglobitic communities present in many Springs Coast Basin springs that straddle the fresh water-salt water transition zone. The median nitrate+nitrite concentration for 12 Floridan aquifer system wells in the planning unit is 0.04 mg/L, near historical statewide background concentrations. Nitrate+nitrite data from 5 surfi cial aquifer system wells in the planning unit is 0.03 mg/L (Table 4.1) . Water quality data from basin springs are limited; the median nitrate/nitrate value from 5 spring stations in the basin (from Health and Crystal Beach Submarine Spring) is 6.0 mg/L, the highest of all springs in the basin (Table 4.2)

. The ammonia median of 0.24 mg/L from 12 Floridan aquifer system wells represents the highest values of any planning unit in the basin and is likely the result of localized sources. The median value of 0.31 mg/L from 5 surfi cial aquifer system wells is likewise higher than any other basin planning unit. Orthophosphate values from 2 springs in the Anclote River/Coastal Pinellas County Planning Unit had a median concentration of 0.07 mg/L; however, one of these springs (Health) had a value exceeding 0.1 mg/L. Twelve Floridan aquifer system wells in the planning unit produced a median value of 0.004 mg/L; however, wells located in northern Pinellas County produced orthophosphate values in excess of 0.1 mg/L. Five surfi

- cial aquifer system wells in the planning unit had a median orthophosphate concentration of 0.036 mg/L. 

# 112 Water Quality Assessment Report: Springs Coast

### The DO median value for 12 Floridan aquifer system wells in the planning unit was 0.66 mg/L. Five surfi cial aquifer system wells in the planning unit had a measured DO level of 0.21 mg/L. According to the draft Group 5 Verifi ed List (July 2006), several WBIDs in the Anclote River/Coastal Pinellas County Planning Unit are impaired for potential ground water-sourced analytes. Beginning in the northwestern portion of the planning unit, WBID 1440A (Spring Bayou Creek) and the adjacent WBID 1508 (Klosterman Bayou Run Tidal) are both listed for low DO and elevated nutrients. The DO listing is based on high BOD. Median total nitrogen values were 0.77 and 0.98 mg/L, respectively, and median total phosphorus values were 0.1 and 0.165 mg/L,respectively (typical average estuarine total nitrogen and total phosphorus values are 0.8 mg/L and 0.1 mg/L, respectively [U.S. Environmental Protection Agency (EPA), 2007]). Median BOD values were 2.0 and 2.9 mg/L, respectively. Based on elevated well and spring ground water values, and the locationof these waterbodies in a ground water discharge area, ground water contributions to these surface waterbodies could at least be partially responsible
for the verifi ed listings. The EPA has published a TMDL for Klosterman Bayou Run Tidal (EPA, 2007), calling for nutrient reductions for total nitrogen and total phosphorus.WBID 1538 (Curlew Creek Estuary) is listed for elevated fecal coliforms and elevated nutrients, and although it might receive some nutrient
infl ux from ground water discharge, this is an unlikely source due to the WBID’s location and the nature of this estuarine system. There are no data to associate the high coliform measurements with a ground water source.
A number of WBIDs in the western half of the Pinellas Peninsula are listed for high nutrients and low DO: WBID 1567 (Stevenson Creek), WBID 1668A (St. Joe Creek), WBID 1668B (Pinellas Park Ditch No. 5),WBID 1668E (St. Joe Creek Tidal Estuary), and WBID 1709F (Frenchmann’s Creek Basin). Two of these (WBIDs 1668A and 1668B) have TMDLs set by the EPA (EPA, 2007). All are listed as high or medium priority for TMDL development. In each case, total phosphorus and nitrogen are elevated compared with expected values. For total phosphorus, the range of values for these WBIDs was 0.07 to 0.22 mg/L, and the median value was 0.12 mg/L, which is comparable to the median surfi cial aquifer well total phosphorus value of0.13 mg/L. Natural phosphorus leaching from the Hawthorn Group, present in places near the surface in this area, could be a source of this nutrient. However, the range of total nitrate values for these WBIDs was 0.93 to1.30 mg/L, with a median value of 1.18 mg/L—nearly an order of magnitude above the median surfi cial aquifer well total nitrate+nitrite value of 0.13 mg/L (Table 4.1) . Due to the nature of the surfi cial aquifer system lithology along the lower Pinellas Peninsula (interlayered sands, sandy shell beds, clayey sands, and sandy clays), any ground water contributions would likely represent recent recharge and would be low in volume compared with Floridan aquifer system contributions to surface waterbodies to the north. The shallow ground water contribution could still be a factor to consider in the allocation of phosphorus loads in TMDL development for some

streams.



## Recommendations

High nitrate contributions, primarily from Floridan aquifer system springs in the northern four planning units, are the most insidious effects of ground water discharge into surface waterbodies of the upper and middle Springs Coast Basin. Unlike phosphorus, nitrate is a conservative analyte, with no signifi cant breakdown or uptake once it enters the aquifer. Nitrate loads delivered by the springs have resulted in significant ecological imbalances in many of the receiving waters. These have manifested as extensive algal growth, algal blooms, the overgrowth of invasive plants, and the depletion of natural aquatic vegetation.Several previous studies, notably those by Jones, Upchurch, Champion, and DeWitt (1997) and Jones, Upchurch, and Champion (1998), have found that inorganic fertilizers are the primary sources of nitrogen in the Floridan aquifer system ground waters of this region. Land use has changed rapidly over the last 50 years with population growth, resulting in an explosion of subdivision development adjacent to and upgradient of large coastal springs. These areas have well-drained sandy soils low in natural nutrients, and fertilizers have been used to make turfgrass and other plants thrive.
With the transition from natural woodlands to watered and fertilized lawns, golf courses, and in some areas septic tanks, nitrate sources are now present that did not previously exist. The sandy, well-drained soils of the Gulf Coastal Lowlands and portions of the Brooksville Ridge are naturally low in organic content, and precipitation falling in this region can easily and rapidly leach nutrients from fertilized turf down through the sandy soils and directly into the Floridan aquifer system. Most of the conduit systems feeding these springs are shallow and thus even more likely to pick up near-surface nutrients from these land uses. To reverse the trend of high nitrate levels in area surface and ground water, an intense nutrient management program should be instituted for the four northern planning units. Elements of this program could include the development of effective turfgrass best management practices (BMPs) specifi c to the region, the required use of slow-release or organic fertilizers, and the use of xeriscaping or native ground covers in place of traditional turf, because these require less fertilizer and water to thrive. Despite the traditional triggers that elevate a WBID to listed and/or
verifi ed status, there are no nutrient-impaired waterbodies on the Springs
Coast Verifi ed List for the 4 northern planning units. However, it has been
documented in numerous scientifi c studies that rapid biological changeshave occurred in virtually all of these coastal spring-fed surface waterbodies. Native submerged aquatic vegetation has disappeared altogether in many locations or been replaced with invasive species and algal mats. Visibility in some spring-fed waterbodies has declined due to chlorophyll

### in the water. According to Stevenson et al. (2007), decreasing nitrate levels below 0.25 mg/L or lower will begin to discourage algae growth in springruns. A regular periodic biological assessment program should be initiated in Kings Bay, the Homosassa River, the Chassahowitzka River, and the Weeki Wachee River, much like those already being performed by the Department in other Florida spring runs. Signifi cant ground water input to surface waterbodies is most likely in
the northern Verifi ed List waterbodies in the Anclote River/Coastal PinellasCounty Planning Unit. Steps like those described above might be applicable in these WBIDs, but it is likely that other infl uences are more important in this area, including poorly maintained septic systems and stormwater
effects. Ground water effects on Verified List WBIDs in the southern portion of the planning unit are likely overshadowed by other factors.

Public Participation

The Florida Department of Environmental Protection (Department) has worked with a variety of stakeholders and held public meetings on developing and adopting the Verifi ed Lists of impaired waters for the six Group 5 basins across the state. Table 5.1 lists the statewide schedule for the development and adoption of the Group 5 Verifi ed Lists, including the public meetings. The schedule for the Springs Coast Basin is highlighted in boldface type. Basin-specifi c draft Verifi ed Lists of waters that met the requirements of the Impaired Surface Waters Rule (IWR) were made available to the public. The lists were placed on the Department’s Total Maximum Daily Load (TMDL) Program Web site, at http://www.dep.state.fl .us/water/tmdl, and were also sent on request to interested parties by mail or via e-mail. Citizens were given the opportunity to comment on the draft lists in person and/or in writing. Public meetings were held across the state to encourage public participation on a basin-by-basin basis. The Department also accepted written comments for 45 days. Following the public meetings for the Group 5 basins, revised draftlists were made available to the public, who had the opportunity to comment on these revised lists either in writing and/or at a fi nal public meeting in Tallahassee. Comments on any of the lists were accepted and considered throughout the full comment period. The fi nal basin-specifi c Verifi ed Listsdeveloped through the public participation process are adopted by Secretarial Order and submitted to the U.S. Environmental Protection Agency (EPA) as the state’s current 303(d) list of impaired waters.



## Identification of Impaired Waters

As discussed in Chapter 2, waters on the Verifi ed and Planning Lists must meet specifi c thresholds and data sufficiency and data quality requirements in the IWR (Rule 62-303, Florida Administrative Code [F.A.C.]). Appendix A describes the legislative and regulatory background for the development of the Planning and Verifi ed Lists. Appendix D contains a methodology that describes the criteria and thresholds required for both
lists under the IWR. Any waters that do not have sufficient data to be analyzed in accordance with the requirements of the IWR will remain on the 1998 303(d) list of impaired waters maintained by the EPA. These waters are not delisted, and they will be sampled during the next phases of the watershed management cycle so that their impairment status can be verifi ed.

## Documentation of Reasonable Assurance

Under the Florida Watershed Restoration Act, the Department will not place impaired waters on the Verifi ed List if reasonable assurance is provided that these waters will attain water quality standards in the futureand will make reasonable progress toward attaining water quality standards by the time the next 303(d) list of impaired waters is scheduled to be submitted to the EPA. Reasonable assurance can be provided if existing or proposed technology-based effl uent limitations and other pollution control programs under local, state, or federal authority are expected to result in the attainment of water quality standards. Examples include Surface Water Improvement and Management Program restoration projects that provide ongoing monitoring, and permitted facilities that upgrade to advanced treatment or remove discharges to surface waters. Table 5.2 lists the major elements of reasonable assurance, and Appendix C provides additional
information. As part of the 303(d) assessment of the Springs Coast Basin, the Department received documentation from Pinellas County designed to provide reasonable assurance that proposed pollution control mechanismswould effectively address the nutrient-related impairment of Lake Seminole. While the fi nal agency action on this submittal will not occur until adoption of the Verifi ed List of impaired waters for the Group 5 basins, the Department has concluded that the Lake Seminole Reasonable Assurance Plan (plan) provides reasonable assurance that the lake will be restored. As such, the Department will approve the reasonable assurance proposal as part of the list adoption and will place Lake Seminole in assessment Category 4b.

## The Verified List of Impaired Waters

Table 5.3 contains the Verifi ed List of impaired waters for the Springs Coast Basin, based on the water quality assessment performed using IWR Run 29, as of September 17, 2007. Figure 5.1 shows waters on the Verifi ed List for the entire basin as of September 17, 2007, and the projectedyear for TMDL development. For presentation purposes, the entire watershed for the listed water is highlighted. However, only the main waterbody in the assessment unit has been assessed, and other waters in the watershed may not be impaired. During Phase 2 of the basin management cycle, draft Verifi ed Lists for all 6 Group 5 basins go out to the public in the summer. Following a series of public meetings and an extended period for public comment, the Department’s Secretary generally adopts the Verifi ed List for each basin in the fall. Subsequently, errors and omissions to the list are corrected, and the Secretary signs an order amending the Verifi ed List. Each order is offi

- cially noticed in the Florida Administrative Weekly ; this initiates a 21-day period to fi le a petition challenging the order and a 30-day period to appeal
the order.

This includes the following WBIDs: 1339, 1341I, 1345A, 1373, 1382, 1440AB, 1479, 1508, 1528, 1528A, 1528B, 1528C, 1535, 1538, 1554, 1562, 1567, 1618B, 1618C, 1641, 1662, 1668E, 1694A, 1694B, 1694C, 1694D, 1694F, 1709F, 1716, 1716A, 8044C, 8045A, 8045B, 8045C, 8045D, 8046, 8046A, 8047, 8047A, 8047B, 8047C, 8048, 8048A, 8048B, 8048C, 8041, 8039, 8039A, 8040, 8042, 8042A, 8043, 8044, 8044A, 8044C, 8044D. For these WBIDs, there
were exceedances of the
annual threshold of 0.43 mg/kg of mercury in fish.

Notes:

1 Florida’s waterbody classifications are defined as follows: Class I: Potable water supplies Class II: Shellfish propagation or harvesting Class III: Recreation, propagation, and maintenance of a healthy, well-balanced population of fish and wildlife Class IV: Agricultural water supplies Class V: Navigation, utility, and industrial use (there are no state waters currently in this class)

2 Priority and schedule reflect the priority established for the WBID in the 1998 303(d) list. Where a parameter was 1998 303(d) listed, the priority shown in the 1998 303(d) list was retained if it was originally high, or changed to medium if it was origi nally low. In the case of mercury in fish, the priority remains low. Where a parameter was only identified as impaired under the IW R, priorities of high, medium, or low were used.

### Pollutants Causing Impairments Of the 160 water segments in the Springs Coast Basin, 35 waters are

i mpaired for at least 1 parameter, and a TMDL is required for these waters. There are a total of 56 parameter listings for impairment following the methodology in Appendix D . The Anclote River/Coastal Pinellas County Planning Unit has the largest number of impaired parameter listings with 45, followed by the Middle Coastal Planning Unit with 6 listings. Table 5.4 summarizes the major parameters for which potential impairments were identifi ed. The most common parameter causing impairment throughout theSprings Coast Basin is fecal coliforms with 20 listings, followed by dissolved oxygen (DO) with 19 listings, and nutrients (chlorophyll a ) with 13 listings. There are also 57 segments listed due to fi sh consumption advisories for mercury in fi sh; this includes coastal waterbody identifi cationnumbers in the Middle Coast Planning Unit as well as the freshwater segment Lake Nash. The state has also issued limited consumption advisories for king mackerel (Scomberomorus cavalla) and bull shark (Carcharhinus leucas) which applies to fi sh species having mercury levels of 0.5 to 1.5 parts per million. Table 5.4 shows that DO levels exceeding criteria are a potential causeof impairment in a number of waterbody segments in the basin. As previously mentioned, low DO levels are often natural and not always attributable to pollutants. For this reason, additional work was conducted to differentiate between pollutant-related and other causes of low DO before
the Verifi ed List for the basin was developed.As required by the IWR, the Department must identify the pollutants causing or contributing to DO exceedances in order to place DO on

### the Verifi ed List. If a water segment is on the Verifi ed List for both DO and nutrients, nutrients are identifi ed as a pollutant contributing to DOexceedances. The Department also applies the following analysis to identify the pollutant(s) contributing to DO exceedances:

1. The waterbody segment median values for biological oxygen demand, total nitrogen (TN), and total phosphorus (TP) are
determined for the verifi ed period (i.e., January 1, 1999, to June 30, 2006).
2. The median values are then compared with the screening levels for the appropriate waterbody type. The screening levels represent the 70th percentile value of data collected from streams, lakes, or

estuaries (Table 5.5)

. 3. If a waterbody segment’s median value exceeds the screening level, the parameter is identifi ed as a pollutant contributing to the
exceedances.

### Table 5.6 provides the median values for waterbody segments where
there is a suffi cient number of DO exceedances to place the water on the
Verifi ed List. If a water has a sufficient number of exceedances for placement on the Verifi ed List, but the median values are less than the screening levels, the DO for that segment is included on the Planning List. Additionally, to place a waterbody segment on the Verifi ed List for nutrients, the Department must identify the limiting nutrient or nutrients on the Verifi ed List, as required by the IWR. The following method is used to identify the limiting nutrient(s) in streams and lakes:

1. The ratios of TN to TP are calculated for each paired value of TN and TP (per sampling event) collected during the verifi ed period.

2. The individual ratios over the entire verifi ed period are evaluated to determine the limiting nutrient(s). If all the sampling event ratios are less than 10, nitrogen is identifi ed as the limiting nutrient, and if all the ratios are greater than 30, phosphorus is identifi ed as the limiting nutrient. Both nitrogen and phosphorus are identifi ed as limiting nutrients if the ratios are between 10 and 30.

Adoption Process for the Verified List of Impaired Waters
The Verifi ed List must be submitted in a specifi c format (Section 62-303.710, F.A.C.) before being approved by order of the Department’s Secretary. The list must specify the pollutant and concentration causing the impairment. If a waterbody segment is listed based on water quality criteria exceedances, then the list must provide the applicable criteria.However, if the listing is based on narrative or biological criteria, or impairment of other designated uses, and the water quality criteria are met, the
Verified List is required to specify the concentration of the pollutant relative to the water quality criteria and explain why the numeric criterion is not adequate. For waters with exceedances of the DO criteria, the Department must identify the pollutants causing or contributing to the exceedances and list both the pollutant and DO in the Verifi ed List. For waters impaired by nutrients, the Department is required toidentify whether nitrogen or phosphorus, or both, are the limiting nutrients, and specify the limiting nutrient(s) in the Verifi ed List.
The Verifi ed List must also include the priority and schedule for TMDL development established for a waterbody segment and note any waters that are being removed from the current Planning List. In future watershed management cycles, the list must also note waters that are being removed from any previous Verifi ed List for the basin. 

# 139 Water Quality Assessment Report: Springs Coast

# Chapter 6: TMDL Development, Allocation, and Implementation

Prioritization of Listed Waters

Following the identifi cation of impaired waters on the 303(d) list, the Florida Department of Environmental Protection (Department) determines priorities for developing total maximum daily loads (TMDLs) in Phase 3 of the watershed management cycle. When TMDLs are established, general allocations of pollutant load reductions are identifi ed, at least to the level of point and nonpoint source categories. Because TMDLs cannot be developed for all listed waters during a single watershed management cycle, waterbodies will be prioritized using the criteria in the Impaired Surface Waters Rule (IWR) (Section 62-303.500, Florida Administrative Code). The rule states that, when establishing the TMDL development schedule for waters on the Verifi edList, the Department will prioritize impaired waterbody segments according to the severity of the impairment and each waterbody’s designated uses, taking into account the most serious water quality problems, the most valuable and threatened resources, and the risk to human health and aquatic life. Under the IWR, the determination of high-, low-, and medium- priority waters is based on the following criteria.

High-priority waters:

• Waterbody segments where the impairment poses a threat to potable

water supplies or human health;
• Waterbody segments where the impairment is due to a pollutant

regulated by the Clean Water Act and the pollutant has contributed to the decline or extirpation of a federally listed threatened or endangered species, as indicated in the Federal Register listing the species; or
• Waterbody segments verifi ed as impaired that are included on the U.S. Environmental Protection Agency’s (EPA’s) 1998 303(d) list as high priority.

Low-priority waters:

• Waterbody segments that are listed before 2010 because of fish consumption advisories for mercury in fi sh (due to the current insuffi

- cient understanding of how mercury cycles in the environment); 

# 141 Water Quality Assessment Report: Springs Coast

### • Canals, urban drainage ditches, and other artifi cial waterbody segments that are listed only due to exceedances of dissolved oxygen (DO) criteria; or
• Waterbody segments that were not on the Planning List but were

identifi ed as impaired during Phase 2 of the watershed management cycle and were included on the Verifi ed List, unless the segment meets the second high-priority criterion.
• The EPA has also proposed assigning to this category the list of additional waterbody segments that the agency developed using its ownevaluation methodology, until the Department has had the opportunity to investigate these waterbodies further.

All segments not designated high or low priority are medium priority, and are prioritized based on the following factors:

• The presence of Outstanding Florida Waters;
• The presence of waterbody segments that fail to meet more than one

designated use, i.e., aquatic life, primary contact and recreation, fi sh
and shellfi sh consumption, drinking water, and the protection of human health;
• The presence of waterbody segments that exceed an applicable water

quality criterion or alternative threshold with a frequency of greater than 25 percent at a minimum confi dence level of 90 percent;
• The presence of waterbody segments that exceed more than one

applicable water quality criterion; or
• Administrative needs of the TMDL Program, including meeting a

TMDL development schedule agreed to with the EPA, basin priorities related to the Department’s watershed management approach, and the number of administratively continued permits in the basin.

The Department is adhering to the TMDL schedule established in the Consent Decree between the EPA and Earthjustice for waters on the 1998 303(d) list that are also identifi ed as impaired under the IWR.
Table 6.1 lists the high-priority waters for TMDL development in the Springs Coast Basin. The nine waters listed in the table were also high priorities on the 1998 303(d) list. Of these, four segments had suffi cient water quality information to verify a parameter as the cause of impairment: DO, fecal coliforms, and nutrients (chlorophyll a ) for Klosterman Bayou Tidal; DO and nutrients (chlorophyll a ) for Stevenson Creek Tidal; DO, fecal coliforms, and nutrients (chlorophyll a ) for St. Joe Creek; and DO, fecal coliforms, and nutrients (chlorophyll a ) for Pinellas Park Ditch No. 5. The Department could not verify the remaining impairments, and the establishment of those TMDLs will be the EPA’s responsibility.

* All of the waters included in Table 6.1 are classified as high priority under the category of assessment status with 2006 as the priority year for TMDL development. Note also that the EPA will establish TMDLs for those parameters that could not be verified impaired.



## Total Maximum Daily Load Development

During Phase 3 of the watershed management cycle, TMDLs will be developed for both point and nonpoint sources of pollutants in impaired waterbodies and will be adopted by rule at the end of this phase. TMDL development involves determining the maximum amount ofa given pollutant that a waterbody can assimilate and still meet the applicable numeric or narrative water quality criterion for the pollutant. In most cases, this “assimilative” capacity will be determined using computer modeling (both hydrodynamic and water quality models) that predicts the fate and transport of pollutants in the receiving waters. Modeling for the typical TMDL will include model setup, calibration, and verification, followed by a variety of model runs that determine the assimilative capacity of
the water under worst-case conditions. State law and federal regulations require that TMDLs include a margin of safety (MOS) that takes into account “any lack of knowledge concerning the relationship between effl uent limitations and water quality” (Section 303[d][1][C], Clean Water Act). The EPA has allowed states to establish either a specific MOS (typically some percentage of the assimilative capacity) or an implicit MOS based on conservative assumptions in the modeling. To date, the Department has elected to establish an implicit MOS based on predictive model runs that incorporate a variety of conservative assumptions. (They examine worst-case ambient flow conditions and worstcase temperature, and assume that all permitted point sources discharge at their maximum permitted amount.) 

# 145 Water Quality Assessment Report: Springs Coast

### It is important to note that TMDLs will be developed only for the actual pollutants causing the impairment in the listed waterbody. These are called the “pollutants of concern.” In Florida, the most commonlylisted pollutants of concern are nutrients, sediments, and coliform bacteria. TMDLs will not be developed for impairments not due to pollutant discharges—for example, natural conditions, physical alterations such as dams and channelization, or changes in the fl ow of water. In other cases, a waterbody may be deemed potentially impaired based on bioassessment data or toxicity data. In these cases, the Department must determine the actual pollutant causing the impairment before a TMDL can be developed.



## Total Maximum Daily Load Allocation and Implementation

Initial Allocation of Pollutant Loadings The Florida Watershed Restoration Act (FWRA) requires that a
T MDL include the “establishment of reasonable and equitable allocations . . . among point and nonpoint sources . . . .” The Department refers to this as the “initial allocation,” which is adopted by rule. For the purposes of allocating the required pollutant loadings, the term “point sources” primarily includes traditional sources such as domestic and industrial wastewater discharges. Recent EPA guidance requires states to include as point sources those stormwater systems that are covered by a National Pollutant Discharge Elimination System (NPDES) stormwater permit. However, NPDES- permitted stormwater discharges are not subject to the same types of
effl uent limitations, cannot be centrally collected and treated, and typically have not invested in treatment controls to the same degree as traditional point sources. Nonpoint sources include intermittent, rainfall-driven,diffuse sources of pollutants associated with everyday human activities, including runoff from urban land uses, agriculture, silviculture, and mining; discharges from failing septic systems; and atmospheric deposition. These point and nonpoint defi nitions do not directly relate to whether a source is regulated. Some nonpoint sources such as stormwater systems are permitted under the regulatory programs of the Department or watermanagement districts, while others, such as agricultural stormwater discharges, are not. This distinction is important because the implementation of the allocations to nonpoint sources outside the authority of regulatoryprograms will require cooperation from dischargers to implement best management practices (BMPs) voluntarily. While a detailed allocation will ultimately be necessary to implement a TMDL fully, a key goal of the initial allocation is to assign responsibility for pollutant load reductions between point and nonpoint sources. For point sources, allocations will be implemented through the Department’sNPDES wastewater and stormwater permitting programs. The implementation of nonpoint source load reductions will be done through a combination of regulatory and nonregulatory processes. Initial allocations of pollutant loadings will also be made to historical sources (e.g., the phosphorus-laden sediments at the bottom of a lake) and 

# 146 Water Quality Assessment Report: Springs Coast

### upstream sources (those entering into an impaired waterbody). Upstream sources include sources outside Florida, and these sources will receive
reduced allocations similar to in-state sources. The FWRA provided direction for the allocation of TMDLs and directed the Department to provide guidance on the allocation process byestablishing an Allocation Technical Advisory Committee (ATAC), consisting of representatives of key stakeholder groups. The committee recommended a three-step process for developing initial allocations and addressed detailed allocations for nonpoint sources, stakeholder involvement, the use of BMPs, and other TMDL implementation issues (Department, 2001).

Implementation Programs and ApproachesThe FWRA designates the Department as the lead agency in coordin ating the implementation of TMDLs. Existing programs and approaches through which TMDLs may be carried out include the following:

• Permitting and other existing regulatory programs, such as NPDES

permits, domestic and industrial wastewater permits, and stormwater/Environmental Resource Permits ( Table 6.2 lists the municipal NPDES stormwater permittees in the Springs Coast Basin);
• Local land development codes;
• Nonregulatory and incentive-based programs, including BMPs, cost

sharing, waste minimization, pollution prevention, new approaches to land use design and development, and public education;
• Basin Management Action Plans (B-MAPs) developed under the

FWRA;
• Other water quality management and restoration activities, for

example, Surface Water Improvement and Management plans approved under Section 373.453, Florida Statutes;
• Pollutant trading or other equitable economically based agreements;
• Public works, including capital facilities; or
• Land acquisition.

These programs and approaches will be carried out at local, regional, state, and possibly federal levels. TMDL implementation will require extensive stakeholder involvement throughout the state and, in some cases,
between Florida and other states. Appendix A provides additional details on the implementation programs and approaches listed here.

## Development of Basin Management Action Plans

The FWRA authorizes the Department to develop B-MAPs for implementing TMDLs. These plans will be developed with extensive stakeholder input to build consensus on detailed allocations based on the initial general allocations to categories of discharges.
The B-MAPs will contain fi nal allocations, strategies for meeting the allocations, schedules for implementation, funding mechanisms, applicablelocal ordinances, and other elements. In cases where stakeholder consensus could not be reached on detailed allocations and/or a B-MAP within a reasonable time, the Department will develop the allocations. Once a B-MAP is developed, the Department will make it available for public review and comment. Guidance for the content and format of the B-MAPs is being developed; the plans are likely to include a description of both regulatory and nonregulatory approaches to meeting specifi c TMDLs.

Appendix A: Legislative and Regulatory Background on the Watershed Management Approach and the Implementation of Total Maximum Daily Loads

Federal and State Legislation on Surfa ce Water Quality and Total Maximum Daily Loads

Clean Water Act

Congress enacted the Clean Water Act in 1972 with the goal of restoring and maintaining the “chemical, physical, and biolog ical integrity of th e nation’s waters” (33 U.S.C. § 1251[a]). The ultimate goal of the act is to eliminate the “discharge of [all] pollutants into navigable wate rs” (33 U.S.C. § 1251[a][1]). Section 305(b) of the Clean Wate r Act requires states to report biennially to the U.S. Environmental Protection Agency (EPA) on th eir water quality. The 305(b) assessment report provides information on the physical, chem ical, biological, and cultural features of each river basin in Florida. This initial assessment provides a co mmon factual basis for identifying information sources and major issu es, and for determining the future changes, strategies, and actions needed to preserve , protect, and/or restore water quality. Understanding the physical framework of each basin allows the development of a science-based methodology for assessing wate r quality and an accurate picture of the waters that are most impaired or vulnerable to contamination. Section 303(d) of the Clean Wa ter Act requires states to submit to the EPA lists of surface waters that do not meet applicable water quality standards and establish total maximum daily loads (TMDLs) for each of th ese waters on a schedule. A pollution limit is then allocated to each pollutant source in an individual river basin. A TMDL represents the maximum amount of a given pollutant that a waterbody can assimilate and meet all of its designated uses (see Noteworthy on Florida’s surface water quality classifications for a listing of thes e classifications). A waterbody that does not meet its designated use is defined as impaired

.

NOTEWORTHY: FLORIDA’S SURFACE WATER QUALITY CLASSIFICATIONS
Florida’s water quality standards program, the f oundation of the state’s program of water quality management, designates the “present and future most beneficial uses” of the waters of the state (Subsection 403.061[10], Florida Statutes [F.S.]). Water quality criteria, expressed as numeric or narrative limits for specific parameters, describe the water quality necessary to maintain these uses for surface water and ground water. Florida’s surface water is protected for five designated use classifications, as follows:

Class I Potable water supplies Class II Shellfish propagation or harvesting Class III Recreation, propagation, and main tenance of a healthy, well-balanced population of fish and wildlife Class IV Agricultural water supplies Class V Navigation, utility, and industrial u se (there are no state waters currently in this class)

# 160 Water Quality Assessment Report: Springs Coast



## Florida Watershed Restoration Act

In 1998, the EPA settled a lawsuit with th e environmental group Earthjustice over Florida’s TMDL Program. The Consent Decr ee resulting from the lawsuit requires all TMDLs on the state’s 1998 Section 303(d) list of impaired waters to be developed in 13 years. If the state fails to develop the TMDLs, the EPA is required to do so. In response to concerns about the TMDL la wsuit and in recognition of the important role that TMDLs play in re storing state waters, the 1999 Fl orida legislature enacted the Florida Watershed Restoration Act (FWRA) (Cha pter 99-223, Laws of Florida). The act clarified the Florida Department of Envir onmental Protection’s (Department) statutory authority to establish TMDLs, required th e Department to develop a methodology for identifying impaired waters, specified that the Department could develop TMDLs only for waters on a future state list of im paired waters developed using this new methodology, and directed the Department to es tablish an Allocation Technical Advisory Committee (ATAC) to address the allocation pr ocess for TMDLs. The act also declared Lake Okeechobee impaired and, as required under the TMDL Consent Decree, allowed the state to develop a TMDL for the lake (see Noteworthy for a description of the legislation’s major provisions).

NOTEWORTHY: THE FLORIDA WATERSHED RESTORATION ACT

The Florida Watershed Restoration Act cont ains the following major provisions:



# • Establishes that the 303(d) lis t submitted to the EPA in 1998 is for planning purposes only.



# • Requires the Department to adopt 303(d) listi ng criteria (that is, the methodology used to define impaired waters) by rule.



# • Requires the Department to verify impairm ent and then establish a Verified List for each basin. The Department must also evaluate whether proposed pollution control programs are sufficient to meet water quality standards, lis t the specific pollutant(s) and concentration(s) causing impairment, and adopt the basin-specific 303(d) list by Secretarial Order.



# • Requires the Department’s Secretary to adopt TMDL allocations by rule. The legislation requires the Department to establish “reasonabl e and equitable” allocations of TMDLs, but does not mandate how allocations will be made among individual sources.



# • Requires that TMDL allocations consider existing treatment levels and management practices; the differing impacts that pollutant sources may have; the availability of treatment technologies, best management practices (BMPs), or other pollutant reduction measures; the feasibility, costs, and benefits of achieving the allocation; reasonable time frames for implementation; the potential applicability of moderating provisions; and the extent that nonattainment is caused by pollutants from outside Florida, discharges that have ceased, or alteration to a waterbody.



# • Required a report to the legislature by Febr uary 2001 addressing the allocation process.

### Water Quality Assessment Report: Springs Coast 

# 161

• Authorizes the Department to develop basin plans to implement TMDLs, coordinating with the water management districts, the Florida Depa rtment of Agriculture and Consumer Services (DACS), the Soil and Water Conservation Distri cts, regulated parties, and environmental groups in assessing waterbodies for impairm ent, collecting data for TMDLs, developing TMDLs, and conducting at least one public meeting in the watershed. Implementation is voluntary if not covered by regulatory programs.



# • Authorizes the Department and DACS to dev elop interim measures and BMPs to address nonpoint sources. While BMPs would be adopted by rule, they will be voluntary if not covered by regulatory programs. If they are ad opted by rule and the Department verifies their effectiveness, then implementation will provi de a presumption of compliance with water quality standards.



# • Directs the Department to document the effect iveness of the combined regulatory/voluntary approach and report to the legislature by January 1, 2005. The report will include participation rates and recommendat ions for statutory changes.



## Determining Impairment Based on the State’s Impaired Surface Waters Rule

Section 303(d) of the federal Clean Wate r Act and the FWRA describe impaired waters as those waterbodies or waterbody se gments that do not meet applicable water quality standards. “Impairment” is a broa d term that includes designated uses, water quality criteria, the Florida antidegrada tion policy, and moderating provisions (see Noteworthy for explanations of these terms). The state’s Identification of Impaired Surface Waters Rule (IWR) (Rule 62-303, Florida Administrative Code [F.A.C.]) was developed in cooperation with a Technical Advisory Committee and adopted by the Fl orida Environmental Regulation Commission on April 26, 2001. It provides a science-ba sed methodology for evaluating water quality data in order to identify impaired waters, and establishes specific criteria for impairment based on chemical parameters, the interpretatio n of narrative nutrient criteria, biological impairment, fish consumption advisories, and ecological impairment. The complete text of the rule is available at http://www .dep.state.fl.us/legal/R ules/shared/62-303/62- 303.pdf. The IWR also establishes thresholds for data sufficiency and data quality, including the minimum sample size required and the number of exceedances of the applicable water quality standard for a given sample size that identify a waterbody as impaired. The number of exceedances is based on a statisti cal approach designed to provide greater confidence that the outcome of the water quality assessment is correct. Waters that are identified as impaired through the IWR are prioritized for TMDL development and implementation

.

### NOTEWORTHY: EXPLANATION OF TERMS



# • Designated uses, discussed in an earlier sidebar, comprise the five classifications applied to each of the state’s surface waterbodies.



# • Water quality criteria comprise numeric or narr ative limits of pollutants.



# • The Florida Antidegradation Policy (Sections 62-302.300 and 62-4.242, F.A.C.) recognizes that pollution that causes or contributes to new violations of water quality standards or to the continuation of existing violations is harmful to the waters of the state. Under this policy, the permitting of new or previously unpermitted existing discharges is prohibited where the discharge is expected to reduce the quality of a receiving water below the classification established for it. Any lowering of water quality caused by a new or expanded discharge to surface waters must be in the public interest (t hat is, the benefits of the discharge to public health, safety, and welfare must outweigh any adverse impacts on fish and wildlife or recreation). Further, the permittee must demons trate that other disposal alternatives (for example, reuse) or pollution prevention are not economically and technologically reasonable alternatives to the surface water discharge.



# • Moderating provisions (provided in Subsection 62-302.300[10] and Rules 62-4 and 62-6, F.A.C., and described in Sections 62-302.300, 62-4.244, 62-302.800, 62-4.243, F.A.C., and Sections 403.201 and 373.414, F.S.) include mixing zones, zones of disc harge, site-specific alternative criteria, exemptions, and variances . These provisions are intended to moderate the applicability of water quality standards where it has been determined that, under certain special circumstances, the social, econ omic, and environmental costs of such applicability outweigh the benefits.



## Determining impairment in individual water bodies takes place in two phases. First, in each river basin the Department evaluate s the existing water quality data, using the methodology prescribed in the IWR, to de termine whether waters are potentially impaired. Waters found to be potentially impaired are included on a Planning List for further assessment under Subsections 403.067(2) and (3), F.S. As required by Subsection 403.067(2), F.S., the Planning List is not used to administer or implement any regulatory program. It is submitted to the EPA for informational purposes only. The second step is to assess waters on the Planning List under Subsection 403.067(3), F.S., as part of the Department’s watershed management approach (described in the following section). The Department carries out additional data gathering and strategic monitoring, focusing on these poten tially impaired waters, and determines— using the methodology in Part III, Section 62-303.400, F.A.C.—if a waterbody is, in fact, impaired and if the impairment is caused by pollutant discharges. A Water Quality Assessment Report is pr oduced containing the results of this updated evaluation and a Verified List of impaired waters. The criteria for the Verified List are more stringent than those for the Pla nning List. The Depart ment is required to develop TMDLs for waters on the Verified List under Subsection 403.067(4), F.S. A watershed management plan (called a Basi n Management Action Plan, or BMAP) to

# 163

reduce the amount of pollutants that cause impairments must also be produced and implemented. The Verified List is adopted by Secretar ial Order in accordance with the FWRA. Once adopted, the list is submitted to the EP A for approval as the state’s Section 303(d) list of impaired waters for the basin.



## Implementing Total Maximum Daily Loads

The Watershed Management Approach

The Department's statewide approach to water resource management, called the watershed management approach, is the fr amework for implementing TMDLs as required by the federal and state governments. The a pproach does not focus on individual causes of pollution. Instead, each ba sin is assessed as an entire functioning system, and aquatic resources are evaluated from a basinwide perspective that considers the cumulative effects of human activities. Water resour ces are managed on the basis of natural boundaries, such as river basins, rather than political or regulator y boundaries. Federal, state, regional, tribal, and local governments identify watersheds not meeting clean water or other natural resource goals and work coope ratively to focus resources and implement effective strategies to rest ore water quality. Extensive public participation in the decision-making process is crucial. The watershed management approach is not new, nor does it compete with or replace existing programs. Rather than relying on si ngle solutions to water resource issues, it is intended to improve the health of su rface water and ground water resources by strengthening coordination among such act ivities as monitoring, stormwater management, wastewater treatment, wetland restoration, land acquisition, and public involvement. By promoting the management of entire natural systems and addressing the cumulative effects of human activities on a wate rshed basis, this approach is intended to protect and enhance the ecol ogical structure, function, a nd integrity of Florida’s watersheds. It provides a framework for sett ing priorities and focu sing the Department’s resources on protecting and restoring water quality, and ai ms to increase cooperation among state, regional, local, a nd federal interests. By emphasizing public involvement, the approach encourages stewardship by all Fl oridians to preserve water resources for future generations. The watershed approach is intended to speed up projects by focusing funding and other resources on priority water quality problems, strengthening public support, establishing agreements, and funding multiage ncy projects. It avoids duplication by building on existing assessments and restorat ion activities and promotes cooperative monitoring programs. It encourages accountability for achieving water quality improvements through improved monitoring and the establishment of TMDLs.

# 164 Water Quality Assessment Report: Springs Coast



## The Watershed Management Cycle

As part of the Department’s watershed management approach, TMDLs will be developed, and the corresponding pollutant load ings allocated, as part of a watershed management cycle that rotates through the st ate’s 52 river basins ove r a 9-year period. The cycle’s 5 phases are as follows:

• Phase 1: Preliminary Watershed Evaluation. For each river basin, a Water Quality Status Report is developed, containing a Planning List of potentially impaired waters that may require the establishment of TMDLs. The report characterizes each basin’s hydrologic, ecologi cal, and socioeconomic setting as well as historical, current, and pr oposed watershed management issues and activities. It also contains a preliminary evaluation of major water quality parameters, water quality issues by planning unit, ecological resources, and basinwide pollutant loading trends related to land uses. At the end of Phase 1, a Strategic Monitoring Plan is developed.

• Phase 2: Strategic Mo nitoring and Assessment. Additional data are collected through strategic monitoring and uploaded to STORET. The data are used to verify whether potentially impaired wa ters in each basin are impa ired and to calibrate and verify models for TMDL development. At the end of Phase 2, a Water Quality Assessment Report is produced for each basin that contains a Verified List of impaired waters. The report also provid es an updated and more thorough evaluation of water quality, associated bi ological resources, and current management plans. The Department will adopt the Verified List through a Secretarial Order and submit it to the EPA as the state’s Section 303(d) list of impaired waters.

• Phase 3: Development and Adoption of TMDLs. TMDLs for priority impaired waters in the basin will be developed and adopted by rule. Because TMDLs cannot be developed for all listed waters during a single watershed management cycle due to fiscal and technical limitations , waterbodies will be prioritized using the criteria in the IWR (Rule 62-303, F.A.C.).

• Phase 4: Development of a Basin Management Action Plan. A BMAP will be developed for each basin to specify how po llutant loadings from point and nonpoint sources will be allocated and reduced in order to meet TMDL requirements. The plans will include regulator y and nonregulatory (i.e., volunt ary) and structural and nonstructural strategies, and existing manageme nt plans will be used where feasible. The involvement and support of affected stakeh olders in this phase will be especially critical.

• Phase 5: Implementation of a Basin Management Action Plan. Implementation of the activities specified in the BMAP will begin. This includes carrying out rule development as needed, securing funding, in forming stakeholders and the public, and monitoring and evaluating the implementation of the plan.

### Water Quality Assessment Report: Springs Coast 

# 165

To implement the watershed cycle, the stat e’s river basins have been divided into five groups within each of the Department’s si x districts statewide, and each district will assess one basin each year. Table A.1 shows the basin groups for implementing the cycle in the Department’s districts, and Figure A.1 shows these groups and the rotating cycle in the districts. Table A.2, which lists the basin rota tion schedule for TMDL development and implementation, shows that it will take nine years to complete one full cycle of the state. The watershed management cycle is an iterati ve, or repeated, proce ss. One of its key components is that the effec tiveness of management activ ities (TMDL implementation) will be monitored in successive cycles. M onitoring conducted in Phase 2 of subsequent cycles will be targeted at evaluating whethe r water quality objectives are being met and whether individual waters are no longer impaired. The Department also will track the implementation of scheduled restoration activ ities, whether required or voluntary, to ensure continued progress towards meeting the TMDLs.

Pollutants can enter a waterbody through point source discharges (generally from a specific facility) or nonpoint discharges (e.g., stormwater runoff, septic tanks). Government agencies, businesses, organizati ons, and individuals w ho contribute to these discharges will be asked to share the res ponsibility of attaining TMDLs through load allocations (the amount of a specified pollutant allotted for discharge) that are based on an established TMDL. Table A.3 summarizes these potentially affected stakeholders, and the actions they may be asked to take to help achieve a TMDL.

Table A.3: Potentially Affected Stakeholders and Actions To Achieve TMDLs

Potentially Affected Stakeholders Actions To Achieve TMDL

Municipal stormwater/wastewater programs Reduce and treat urban stormwater runoff through stormwater retrofits, repl acement of septic tanks

Commercial developers, homebuilders, individual homeowners Improve development design and construction, enhance BMPs, replace septic tanks
Municipal and industrial wastewater treatment facilities, National Pollutant Discharge Elimination System (NPDES) permitted facilities Reduce pollutant loadings from permitted discharges

Farming and silviculture operations Reduce and treat runoff through BMPs

Federal, regional, state agencies; regional and local water quality coalitions Carry out waterbody restoration projects



## Permitting and Other Approaches

N ATIONAL P OLLUTANT D ISCHARGE E LIMINATION S YSTEM P ERMITS 

## All point sources that discharge to surf ace waterbodies require an NPDES permit. These permits can be classified into two t ypes: domestic or industrial wastewater discharge permits, and stormwater permits. NPDES-permitted point sources may be affected by the development and implementation of a TMDL. All NPDES permits include “reopener clauses” that allow the De partment to incorporate new discharge limits when a TMDL is established. These new limitations may be incorporated into a permit when a TMDL is implemented or at the next permit renewal, depending on the timing of the permit renewal and workload. For NP DES municipal stormwater permits, the Department intends to insert the followi ng statement once a BMAP is completed:

“The permittee shall undertake those activities specified in the (Name of Waterbody) Basin Management Action Plan in accordance w ith the approved schedule set forth in the
BMAP.”

# 168 Water Quality Assessment Report: Springs Coast

D OMESTIC AND I NDUSTRIAL W ASTEWATER P ERMITS 

## In addition to NPDES-permitted facilities, a ll of which discharge to surface waters, Florida also regulates domes tic and industrial wastewater discharges to ground water via land application. Since ground wa ter and surface water are so intimately linked in much of the state, reductions in loadings from th ese facilities may be needed to meet TMDL limitations for pollutants in surface waters. If such reductions are identified in the BMAP, they would be implemented through modi fications of the existing state permits.

F LORIDA S TORMWATER /E NVIRONMENTAL R ESOURCE P ERMITS 

## With the implementation of the state’s st ormwater treatment rule in 1982, Florida became the first state to require the treatment of stormwater from all new development. Today, except in the area served by the No rthwest Florida Water Management District, new development projects receive an Envir onmental Resource Permit that combines stormwater flood protection, stormwater trea tment, and wetland protection/mitigation into a single permit. These permits are desi gned to obtain 80 percent average annual load reduction of total suspended solids. This le vel of treatment may n eed to be increased, depending on the allocation of load reductions, especially for nutrients. For example, the St. Johns River Water Management District recently adopted basi n-specific criteria for the Lake Apopka watershed that require th e phosphorus loading from new development not to exceed predevelopment phosphorus loading.

L OCAL L AND D EVELOPMENT C ODES 

## Since structural stormwater treatment prac tices can only achieve certain levels of load reductions, and because the hydrologic changes accompanying urban development often cause ecological impacts to aquatic sy stems, local land development codes that promote “low-impact development” are an im portant component of restoring impaired waters. Local codes may need to be reviewed to determine how to promote developments that minimize impervious surfaces (such as reduced street widths or the use of pervious pavements), promote the protecti on of vegetation, promote the protection and restoration of riparian buffers along streams and lakes, and adopt the principles of the Florida Yards and Neighborhoods Progr am in local landscaping codes.

B EST M ANAGEMENT P RACTICES



## 5. Typically, BMPs refer to a practice or combination of practices that, based on sound science and best professional judgment, are determined to be the most effective and practicable means of reducing nonpoint source pollutant discharges and improving water quality. Both economic and technological considerations are included in the evaluation of what is practicable. BMPs may include structural controls (such as retention areas or detention ponds) or nonstructu ral controls (such as street sweeping or public education). Many BMPs have been developed for urban stormwater to reduce pollutant loadings and peak flows. Thes e BMPs accommodate site-specific conditions, including soil type, slope, depth to ground wa ter, and the designati on of receiving waters.

6. The passage of the FWRA increased the emphasis on implementing BMPs to reduce nonpoint source pollutant discharges from agricultural operations. Recognizing that the development and adoption of BMPs might take several years, the legislature authorized the use of Interim Measures (IM s) during the BMP development process for agricultural operations. In e ssence, IMs are a set of l ogical conservation practices designed to reduce agricultura l nonpoint pollutant discharg es based on current knowledge and best professional judgment. These practices will evolve into more formal BMPs as better scientific data on their effectiveness is obtained.
7. Once DACS adopts BMPs, the Department is charged with verifying their effectiveness in reducing ag ricultural nonpoint s ources. Once verified, agricultural operations that have implemented BMPs will receive a waiver of liability and presumption of compliance similar to th at granted a developer who obtains an Environmental Resource Permit.

O THER S TRATEGIES



## 8. The success of implementing nonpoint source TMDL load allocations will require variety, creativity, stakeholder commitment to watershed management, and personal stewardship. In addition to BMPs, othe r possible strategies for meeting TMDLs, restoring water quality, and preventing the fu rther degradation of Florida’s watersheds include cost sharing, waste minimization, pollu tion prevention, new approaches to land use design and development, and pollutant tr ading. The Department will assemble a Technical Advisory Committee to help devel op a pollutant-trading ru le, which must be reviewed by the legislature prior to its adop tion. The Department will also continue to work with local stakeholders on TMDL a llocation issues and im plementation plans.

## Saltwater and Coastal Communities

Marine and coastal environments are sh aped by major factors such as geology, topography, winds, currents and tides, wate r depth, water temperature, and water chemistry. The following describes the major coastal saltwater habitats and communities in the Springs Coast Basin, as well as their associated species.

E STUARIES 

## In most nearshore areas of the basin, th e water is less saline than marine water because of low wave action and the large qua ntities of fresh water discharged through streams, springs, and sheet flow. Salinity pa tterns in these inshore waters are estuarine, as are the plant and anim al species living there. Estuaries play an important role in the lif e cycles of numerous species of fish and invertebrates. For example, the young a nd juvenile populations of many sport and commercial species use estuaries as nursery gr ounds. Of the total commercial fisheries’ catch in the Gulf of Mexico states, between 90 and 97 percent of these species use estuaries during some phase of their life cycle. Along the Springs Coast, there are five dominant intertidal estuarine habitats— brackish marshes, salt marshes, intertidal fl ats, oyster reefs, an d, to a lesser extent, intertidal mangrove forests. Brackish marshes. The Springs Coast comprises one of the largest and most spectacular mixtures of salt marshes and brack ish marshes in Florida. Numerous karst features—such as creek channels, circul ar ponds, bedrock highs, and freshwater springs—characterize much of the area. The low-energy, karstic coastline gives rise to an intricate mosaic of marshes and coastal hammocks, where small changes in elevation, tidal inundation, soil characteristi cs, and freshwater flow c ontrol the various zones of vegetation. Sawgrass (Cladium jamaicense) primarily dominates the marshes, but cattails ( Typha spp.) are codominant or dominant in many areas. Larg e patches of black needlerush (Juncus roemerianus) and other herbs interrupt the sawg rass, particularly near the river channels. The brackish vegetati on is perennial but dies back in the fall, providing organic detritus that feeds species at the base of the food chain. S ubmergent vegetation includes a number of freshwater plants that are tole rant of low salinities, such as eelgrass

# 171

(Vallisneria neotropicalis) , sago pondweed (Potamogeton pectinatus), and wigeongrass (Ruppia maritima). Numerous species of fish and m acroinvertebrates use these areas. Salt marshes. Salt marshes, which dominate the basin’s coastline, represent a transitional zone between terres trial and marine ecosystems. They develop in the zeroenergy areas along the Springs Coast, where they are protected from waves. Salt marshes are highly productive systems because of th e large input of nutrients and organic particulate matter from tides and river fl ows, which support a bundant quantities of phytoplankton, algae, and vascular plants. Salt marshes are generally made up of la rge, homogeneous expanses of dense, grasslike species. Along the Sp rings Coast, black needlerush (Juncus roemerianus) predominates. Smooth cordgrass (Spartina alternifloria) is usually restricted to the narrow fringes bordering the coastline, the e dges of tidal creeks a nd channels, and small islands. Other species present include saltgrass (Spartina patens), marsh spike grass (Distichlis spicata), and glasswort (Salicornia perennis). Cabbage palm (Sabal palmetto), red cedar (Juniperus silicicola) , and live oak (Quercus virginiana) usually dominate the coastal hammock islands; these are widely scattered on limestone outcrops among the Spri ng Coast’s salt marshes and brackish marshes. Saltmarsh species are frequently exposed to harsh and variable conditions. Conditions in the marsh change with tidal ebbs and flows, resulting in salinity, temperature, oxygen, and pH fluctuations. C onditions can also vary from one area to another. Some animal species live permanently in the marshes; others use them only during certain seasons or st ages in their life cycles. Fish are seasonally very abunda nt and diverse. Over 60 species of birds, including wading birds and shorebirds, also use the Sp rings Coast salt marshes for food, nesting areas, and refuges. The tricolored heron (Egretta tricolor) is the most abundant species. The marshes are also an important wintering ar ea for the largest con centration of redhead ducks (Anas acuta) in the southeastern United States and also provide feeding sites for bald eagles ( Haliaeetus leucocephalus)

. Reptiles and mammals found in the basin’s sa lt marshes include the Gulf salt marsh snake ( Nerodia clarkii clarkii), diamondback terrapin (Malaclemys terrapin macrospilota), and American alligator (Alligator mississippiensis), the marsh rabbit (Sylvilagus palustris), marsh rice rat (Oryzomys palustris), hispid cotton rat (Sigmodon hispidus), and Duke’s saltmarsh vole (Microtus pennsylvanicus dukecampbelli)

. Intertidal flats. These comprise the portions of the unvegetated bottoms of estuaries, bays, lagoons, and river mouths that lie between the high- and low-tide marks. Made up of sandy and muddy sediments, they appear barren and unproductive because of the absence of macrophytes, such as marshgrasse s or seagrasses. However, they contain abundant benthic microalgae, bacteria, fungi, and invertebrates; th e latter provide food for numerous species of birds and crabs. Bird species found in the in tertidal flats include herons, egrets, ibises, yellowlegs, sandpipers , plovers, godwits, and curlews. Important invertebrate predators are fiddler crabs (Uca spp.), blue crabs (Callinectes sapidus), stingrays (Dasyatis sabina), and horseshoe crabs (Limulus polyphemus). Oyster reefs. Oysters are typically reef organism s, growing on the shell substrate accumulated from previous generations of oysters. In the Springs Coast Basin, they are

# 172 Water Quality Assessment Report: Springs Coast



## found primarily outside the numerous river mout hs. Tides bring in food and carry away waste. The reefs range in size from small, scattered clumps to massive, solid mounds of living oysters and dead shells. Oyster reefs influence estuaries physically by removing suspended particulates and altering currents, and biol ogically by removing phytoplankt on and other particles and producing large quantitie s of oyster biomass and pseudofeces. The reef also provides habitats for many estuarine organisms. The principal oyster species in the Springs Coast Basin are the eastern or American oyster (Crassostrea virginica) and the crested oyster (Ostreola equestris). Both species grow in a wide range of salin ities. Oysters are commercially harvested in Citrus and Pasco Counties. Oyster reefs usually contain large and diverse numbers of other species, such as marine insects ( Anurida maritima), barnacles (Balanus improvisus), mud crabs ( Eurypanopeus depressus and Panopeus herbstii), and various polychaetes, amphipods, gastropods, bivalves, mussels, and worms. Stone crabs (Menippe mercenaria) are an important commercial fishery along the Springs Coast. The American oystercatcher (Haematopus palliatus) is the most important vertebrate predator of oysters in the area. Intertidal mangrove forests. Mangroves are mainly f ound fringing the outer marsh islands, especially in the s outhern portion of the Springs Coast Basin. Three mangrove species are present: black mangrove (Avicennia germinans), red mangrove (Rhizophora mangle), and white mangrove (Laguncularia racemosa). The black mangrove is found throughout Florida’s Gulf Coast and is the mo st cold resistant; the red mangrove is present as far north as Levy County; and th e white mangrove occurs as far north as Hernando County. Mangroves grow in a variety of soils but fl ourish on muds and fine-grained siliceous sands. Wave and current energy contro l sediment distribution and mangrove development. Mangrove forests modify the substrate through peat deposition. Extensive populations of fungi on the submerged portions of the prop roots, stems, branches, and living and dead leaves convert mangrove leaf material into de tritus that can be used by other species. Fires play an important ro le in mangrove succession. Most fires in Springs Coast mangrove stands are started by lightning and result in small, circular openings in the forest canopy. Mangrove forests support diverse algae that at tach to the prop roots or live in the muddy sediments. Also present is an abunda nt microscopic community of diatoms and dinoflagellates and other filamentous green a nd blue-green algae. A number of salttolerant vascular plants are found in mangr ove stands. These include leather leaves (Acrostichum aureum and A. Danaeifolium), chaff flower (Alternanthera ramosissima), Spanish bayonet (Yucca aloifolia ), lianas, and a variety of bromeliads. A distinctive and highly diverse group of arthropods, mostly insects, lives in the mangrove forests. Other species include the mangrove tree crab (Aratus pisonii), which feeds in the mangrove canopy; numerous small invertebrates that graze on the prop-root algae; and many other filter feeders and carni vores. The mangrove system also provides nursery habitat for the Florida spiny lobster (Panulirus argus). Juveniles are especially abundant in the prop-root system, which pr ovides protection and food. Fish species found here include killifish (Fundulus confluentus), pinfish, silver perch, pigfish,

### Water Quality Assessment Report: Springs Coast 

# 173

anchovies, snook, ladyfish, tarpon, gar, and mangrove snapper. Some of these are fished commercially and recreationally. Amphibians a nd reptiles include four species of marine turtles, three species of lizards (Anolis), and American alligators (Alligator mississippiensis)

. In addition, mangroves harbor a diverse bi rd assemblage: wading birds (herons, egrets, ibises, bitterns, and spoonbills), probi ng shorebirds (clapper rails, willets, and black-necked stilts), floating and diving bi rds (ducks, grebes, loons, cormorants, and gallinules), aerially searching birds (gulls, terns, kingfishe rs, black skimmers, and fish crows), birds of prey (hawks, falcons, vulture s, and owls), and ar boreal birds (pigeons, cuckoos, woodpeckers, flycatchers, thrushes, vi reos, warblers, blackbirds, and sparrows).

M ARINE AREAS 

## Open-water estuarine areas. These areas are characterized by extreme spatial variability, based on daily and seasonal fluctua tions in local salinity and temperature, and wind and tidal mixing. Abundant phytoplankton and zooplankton serv e as the base of the food chain. Permanent fauna live in the estuaries for an entire life cycle. Temporary fauna include the juvenile and larval form s of marine organisms such as polychaetes, fish, shrimp, bivalves, and crabs. These use estuarine areas as nursery grounds, and are dispersed by the currents to different habitats when they reach maturity. Recreationally and commercially important species in the estuaries of the Springs Coast Basin include striped mullet (Mugil cephalus), red drum (Sciaenops ocellatus), spotted seatrout (Cynoscion nebulosus), Gulf menhaden (Brevoortia patronus), Atlantic croaker (Micropogonias undulatus), sea catfish (Arius felis), gafftopsail catfish (Bagre marinus), bay anchovy (Anchoa mitchilli), and striped anchovy ( Anchoa hepsetus). Two species of sea turtles ar e occasionally found here: the Atlantic loggerhead (Caretta caretta) and Atlantic leatherback (Dermochelys coriacea). Soft-bottom areas. Subtidal unconsolidated bottom environments such as mud and sand form extensive areas of habitat in the Springs Coast Basin. They are mainly found between oyster bars and seagrass be ds, and at the mouths of rivers. These areas contain many differe nt kinds of species, most of which are buried in the bottom sediments, or live and feed on the bottom. They include polychaetes, oligochaetes, chironomids, amphipods, bivalv es, and isopods, as well as starfish, sand dollars, blue crabs, spider crabs, benthic fi sh, and skates and rays. Recreationally and commercially important species f ound include southern flounder (Paralichthys lethostigma), northern quahog (Mercenaria mercenaria), sunray venus (Macrocallista nimbosa), and blue crab (Callinectes sapidus)

. Seagrass beds. Seagrasses are an extremely im portant habitat in the nearshore coastal waters of the Springs Coast Basi n. Five species are found: turtlegrass (Thalassia testudinum), manateegrass (Syringodium filiforme), shoalgrass (Halodule wrightii), and star grass (Halophila engelmanii) are abundant, while another star grass species, H. decipiens, is relatively scarce. The seagrasses form essentially a single bed, extending from Florida’s Big Bend area to the open-sa nd areas along the southernmost reaches of the Springs Coast Basin, and covering more than 3,000 square kilometers. They occur in

# 174 Water Quality Assessment Report: Springs Coast



## an offshore band 10 to 35 kilometers wide between St. Marks and Tarpon Springs. The seagrass beds have remained relatively stable over time partly because of the region’s extensive, undisturbed tidal marshes and swamps, which filter sediment carried from upland areas. Seagrasses are extremely vulnera ble to any activities that reduce water clarity, such as dredging and filling. The distribution and composition of seag rass meadows along the Springs Coast depend on salinity levels. Because the major bed-forming species, Thalassia and Syringodium, do not grow in low-sali nity areas, wigeongrass (Ruppia maritima), and brackish-tolerant, freshwater species such as eelgrass ( Vallisneria neotropicalis) dominate the river mouths

. Seagrass levels along the Spri ngs Coast are the highest and least patchy for the Weeki Wachee estuary, be cause of its excellent water clarity and relatively smooth bottom. In contrast, seag rass beds in the Crystal River estuary are intermixed with shoals and bars. Seagrass meadows are highly productive. The nu merous types of algae that attach to the grasses are an important food source fo r many herbivorous species. Seagrasses harbor a large and diverse num ber of animals, ranging from tiny, sessile organisms to large, commercially important fish such as sea trout. Organisms such as gastropods are found on the seagrass blades themselves. Cr ustaceans are especially abundant in the seagrass meadows, both on the blades and in sediments. Fish and scallops are also plentiful. Two scallop species—bay scallops (Argopecten irradians) and calico scallops (A. gibbus)— are found here. Juvenile and adult blue crabs are also found in large numbers. Open marine waters. The basin’s marine open water habitat is physically stable compared with that of the estu aries. Salinity varies only sl ightly throughout the year, and temperatures do not fluctuate as much or as quickly. Phytoplankton species diversity is higher than in the estuaries. Many fish use the estuaries as nursery areas and migrate to deeper marine waters as adults, eventually to spawn. This habitat in cludes prized sport and commercial fish such

as grouper (Mycteroperca spp.), Spanish mackerel (Scomberomorus maculatus), king mackerel (S. cavalla), dolphin (Coryphaena hippurus), billfish (Istioophoridae), and invertebrates such as the brown shrimp (Penaeus aztecus). Five species of threatened or endangered marine turtles are occasionally found in the Springs Coast Basin: the Atlantic green turtle (Chelonia mydas mydas), Atlantic hawksbill (Eretmochelys imbricata imbricata), Atlantic leatherback (Dermochelys coriacea), Atlantic loggerhead (Caretta caretta), and Kemp’s ridley (Lepidochelys kempii). The endangered West Indian manatee (Trichechus manatus latirostris) is also found here.



## Terrestrial and Freshwater Communities

Terrestrial and freshwater communities vary depending on factors such as geology, topography, the amount of sunlight available, flooding, fire, and soil chemistry. The following describes the major terrestrial and freshwater communities in the Springs Coast Basin, as well as their associated species.

# 175

C OASTAL S TRAND 

## The coastal areas in the Springs Coast Ba sin are very flat, sloping imperceptibly from low, flat uplands through a level tidal z one and into the very shallow waters of the Gulf of Mexico. The coastline is relatively sheltered from wave action and tides, and has very small vertical tidal fluc tuations. The horizontal tidal fluctuation, however, is large because the land surface is so flat. Conseque ntly, a band of salt marsh borders most of this low-energy coastline; in inland areas, this gives way to forest. Beaches, sand dunes, or coastal strand fo rests are present in only a few spots— mostly on offshore islands in the basin. The remnants of ancient sand dunes, which are gradually eroding away as the coastline subsid es and sea levels rise, supply the sand for these beaches. Some of the islands support coastal st rand forest (maritime hammock), which is dominated by sand live oak (Quercus geminata) and live oak (Quercus virginiana), in association with cabbage palm (Sabal palmetto), red cedar (Juniperus silicicola), and other trees. The majority of coastal live oak, cabbage palm, and red cedar forest is on low-lying land subject to flooding, and is classified as hydric hammock. Because beaches do not support any living co mmunities of vascular plants, the food chain here is based mainly on detritus and sea wrack washed up by storm tides and waves. This includes seagrasses and other pl ant debris, as well as shells, dead fish, jellyfish, crabs, and other marine creature s. Insects, amphipods, ghost crabs, fiddler crabs, seagulls, and other species feed on the de tritus. In turn, shor ebirds such as gulls and sandpipers feed on the insects, amphipods, and crabs.

S CRUB 

## A small but ecologically signi ficant scrub area is present in southern Pasco County, in the Middle Coastal Planning Unit. Scrub is almost completely restricted to Florida, and many scrub species are endemic—that is, they occur only on the Flor ida peninsula in this habitat. It is, on average, the most xeric (dry and hot) of Flor ida’s communities, and is adapted to natural fires. These burn the vegetation periodically (every 10 to 50 years); plants resprout from their base or roots. Scrub occurs only on we ll-drained sand with a low nutrient content. Scrub vegetation is almost entirely evergr een. It consists of a dense growth of evergreen shrubs and small trees without mu ch herbaceous ground cover. It is often fairly uniform in density from the ground to the top of the canopy, except for mature sand pine scrub, in which the sand pines form a canopy above the rest of the vegetation. In addition to sand pine, scrub plant speci esin the basin incl ude the long-spurred mint (Dicerandra cornutissima), scrub pawpaw (Asimina obovata), Florida rosemary (Ceratiola ericoides), garbaria (Garbaria heterophylla), palafoxia (Palafoxia feayi), scrub palmetto (Sabal etonia), and silkbay (Persea humilis). Animal species in the basom, some of wh ich are endemic to scrub, include the scrub jay (Aphelocoma coerulescens), short-tailed snake (Stilosoma extenuatum), worm lizard (Rhineura floridana), peninsula mole skink (Eumeces egregious onocrepis), central Florida crowned snake (Tantilla relicta neilli), Florida black bear (Ursus americanus floridanus), raccoon (Procyon lotor), white-tailed deer (Odocoileus virginianus), wild

# 176 Water Quality Assessment Report: Springs Coast



## hog (Sus scrofa), gray squirrel (Sciurus carolinensis), Sherman’s fox squirrel (Sciurus niger shermani), and wild turkey (Meleagris gallopavo). Insects include the pushup beetle (Peltotrupes spp.), numerous grasshopper species, and the Florida harvester ant (Pogonomyrmex badius).

H IGH P INE F OREST (S ANDHILL ) 

## Most of the well-drained uplands in the Springs Coast Basin were originally open forests of longleaf pine (Pinus palustris), with a scattered subcanopy of deciduous oaks and a ground cover of wiregrass (Aristida stricta), other grasses, and broad-leaved herbs. Several hundred thousand acres of younger, denser forest of th is type remain, mostly in the Withlacoochee State Forest and elsewhere on the Brooksville Ridge in central Citrus and Hernando Counties. However, there are no virgin sandhill tracts left in Florida. Fire plays a dominant role in the sandh ill community. Historically, it burns mostly in summer every two to three years. When fi re is suppressed, the community is replaced within a century by a xeric (dry) to me sic (moist) hammock of low diversity. Most sandhill species are ad apted to—and in fact depend on—frequent, low-intensity ground fires. Grasses, herbs, and small woody pl ants resprout from th eir bases or roots, while longleaf pine and hard woods such as turkey oak (Quercus laevis), southern red oak (Quercus falcata), and mockernut hickory (Carya tomentosa) have thick bark, stems, branches, and buds to withst and the effects of fire. Longleaf pine cannot reproduce unless fires thin out the unders tory vegetation and leaf litter, allowing the seedlings to take hold. Other plant species f ound here include dwarf blueberry (Vaccinium myrsinites), gopher apple (Licania michauxii), and showy pawpaw (Asimina incarna). The high pine community supports numer ous animal species, many of which are declining. Of these, the gopher tortoise (Gopherus polyphemus) is perhaps the most important. The tortoise’s 15- to 20-foot-long burrows are home to nearly 40 additional species, including the Florida mouse (Podomys floridanus), gray fox (Urocyon cinereoargenteus), indigo snake (Drymarchon corais), coachwhip (Masticophis flagellum), eastern diamondback rattlesnake (Crotalus adamanteus), and gopher frog (Rana capito). Other sandhill species in the basin in clude the red-cockaded woodpecker (Dendrocopos borealis), southeastern kestrel (Falco sparverius), Sherman’s fox squirrel (Sciurus niger shermani), common ground dove (Columbina passerina), loggerhead shrike (Lanius ludovicianus), Bachman’s sparrow (Aimophila aestivalis ), northern bobwhite (Colinus virginianus), eastern bluebird (Sialia sialis), tufted titmouse (Parus bicolor), great crested flycatcher (Myiarchus crinitus), and screech owl (Otus asio). Sandhills dominated by turkey oak (Quercus laevis) are common today on the Brooksville Ridge. Most of the original l ongleaf pines growing in these areas were harvested for use in the rosin industry.

P INE F LATWOODS 

## The pine flatwoods community is found in southern and central Pasco County and a very small area in south-central Hernando C ounty, in the Middle Coastal Planning Unit. It occurs on very flat, poorly drained la nd where the soil is sandy, acidic, and low in

### Water Quality Assessment Report: Springs Coast 

# 177

nutrients. A clay hardpan layer usually under lies the water table, which ranges from 1 to 4 feet below the surface. During wet periods, the soils may remain saturated with water for several months. Conversely, during drough ts, the water table may lie below plant root zones. Both of these conditions, in addi tion to the lack of nutrients and soil acidity, severely stress plant and animal species and restrict species composition. Like the high pine forest, fire plays a si milar role, and some of the dominant plants (such as longleaf pine and wi regrass) are the same. Howeve r, the shrub understory burns less frequently (every two to five years, with considerable variatio n) but more intensely. This community has two layers: a tall forest of pine with a second layer of evergreen shrubs, mostly saw palmetto (Serenoa repens), gallberry (Ilex glabra), and fetterbush (Lyonia lucida). Diverse grasses and wildflowers are also present. Animal species include the pine woods tree frog (Hyla femoralis), southern black

racer (Coluber constrictor priapus), eastern diamondback rattlesnake (Crotalus adamanteus), eastern indigo snake (Drymarchon corais couperi), pine warbler (Dendroica pinus), brown-headed nuthatch (Sitta pusilla), summer tanager (Piranga rubra), blue-gray gnatcatcher (Polioptila caerulea), eastern wood-pewee (Contopus virens), northern bobwhite (Colinus virginianus), Bachman’s sparrow (Aimophila aestivalis), rufous-sided towhee (Pipilo erythrophthalmus), white-eyed vireo (Vireo griseus), Carolina wren (Thryothorus ludovicianus), white-tailed deer (Odocoileus virginianus), wild hog (Sus scrofa), and hispid cotton rat (Sigmodon hispidus)

.

H AMMOCKS


## Hammocks are found in a number of areas in the Springs Coast Basin, mainly in Pasco, Hernando, and Citrus Counties in a br oad north-south belt that lies just inland from the coast. Other areas are located in south-central Hernando County and eastern Citrus, Hernando, and Pasco Counties. These hammocks are particularly important to the fauna of much of the eastern United States , because they support very large populations of overwintering songbirds and provide important habitat for migrants that winter farther south. Scattered in a few spots throughout Florida’s original vast pine forests, these dense hardwood forests develop in places that are protected to some degree from wildfire by bodies of water or swamps. While most hammoc ks occur in flat areas, some are found in slopes along rivers and their tributaries, and on the sides of sinkholes. Hammocks grow in a wide variety of soils, but they are generally found in areas containing relatively fertile soil, with either clay or limerock near the surface. There are three main types of hammocks: xeric (dry), mesi c (moist), and hydric (wet). The dominant trees are usually a mixture of oaks (Quercus spp. ), other hardwoods, understory trees, and shrubs; the individual species vary depending on the type of hammock and its distance from the coast

. The most distinctive feature of hammocks is the invertebrate fauna of the forest floor; these species include snails, ea rthworms, millipedes, isopods, springtails, harvestmen, mites, beetles, orthopterans, di pterans, and hemipterans. In turn these support a diversity of spiders and other predator y insects, amphibians, reptiles, birds, and mammals.

S INKHOLES AND T ERRESTRIAL C AVES 

## Caves are common in the Springs Coast Basi n, particularly in central Citrus and Hernando Counties. Inside the caves, alg ae and fungi predominate, but there are no vascular plants. However, there is often an interesting community of calcareous (mesic) hammock plants in sinkholes or on the rock outcrops associated w ith the caves. Many fern species are largely confined to sinkholes with limerock outcrops. Central Citrus and Hernando Counties contain the best-known populat ions of some of these plants. They include two species of maidenhair fern (Adiantum tenerum and A. capillus-veneris), two species of brake fern (Pteris vittata and P. cretica), a number of species of spleenwort (Asplenium heterochroum, A. resiliens, A. cristatum, A. pumilum, A. verecundum, A. auritum, and A. subtile), southern lip fern ( Cheilanthes microphylla), sinkhole fern (Blechnum occidentale), and several species of wood fern (Thelypteris spp.). Other species include mosses and liverworts. Twenty -four species of pter idophytes (ferns and fern allies) were recorded from Pineola Grotto in Citrus County. There is less animal life in the caves than in surface habitats. Species found in the caves include deer mice (Peromyscus spp.), eastern woodrats (Neotoma floridana), rat snakes (Elaphe spp.), and salamanders. Their main habitat value is for bats. Breeding colonies of the southeastern myotis bat (Myotis austroriparius), sometimes numbering in the thousands, occupy some of the caves duri ng the summer. Several other bat species also use the caves. The bat guano in the caves serves as the base of the food chain for cave invertebrates. These include two spiders (Gaucelmus augustinus and Nesticus pallidus), two springtails (Isotoma notabilis and Tomocerus dubius), and a cave cricket (Ceuthopilus latibuli). The caves also contain mites (Acarina), harvestmen (Phalangida), and other invertebrates—incl uding aquatic invertebrates if water is present.

B AYHEAD 

## Bayheads in the Springs Coast region occur mostly as small, scattered patches of a few acres to perhaps 100 acres. This community is generally defined as a wetland forest dominated by any one or a combination of 3 species of broad-leaved evergreen trees, known as bay trees. Swamp tupelo (Nyssa sylvatica var. biflora), a deciduous tree, is also generally codominant. There is usually a moderately dense shrub layer dominated by broad-leaved, evergreen species. Ferns are often abundant in the ground cover. Soils are acidic and usually made up of peat or organic muck, underlain by sand. Bayheads may either be on seepage slopes or on peat bogs with good drainage. Although found in moist areas, they are usually not subj ect to flooding. They are exposed to fire but, unlike pine communities, are neither adapted to fire nor dependent on it. Plant species found here include loblolly bay (Gordonia lasianthus), sweet bay (Magnolia virginiana), and swamp bay (Persea palustris). Animal species include numerous birds, amphibians, reptiles, and black bears.

M IXED S WAMP 

## There are large areas of mixed swamp all along the Gulf Coast, with one of the largest and best examples in and around th e Chassahowitzka National Wildlife Refuge.

### Water Quality Assessment Report: Springs Coast 

# 179

Mixed swamps generally occur as strands or sloughs, or as the deep-water part of the floodplain forests alongside rive rs, creeks, or lakes. Thes e wetlands are often flooded for months at a time. They are generally tall, dense forests, with an open, deeply shaded understory and sparse ground cover. However, some of the most deeply flooded swamps and most swamps right on the coast have an open canopy of shorter trees and much more shrub and groundcover vegetation. Soils in mixed swamps are usually sand or clay over limerock, with varying amounts of muck on the surface. Becau se the swamps are generally connected hydrologically to an established drainage system, the water is generally flowing except during very low water. The soil never dries out much below the surface. Mixed swamps are flooded a little more than half the time. They rarely, if ever, burn, except for individual trees struck by lightning. Mixed swamps are very fertile and pr oductive communities, but they are not especially diverse. Tree species such as green ash (Fraxinus pennsylvanica), pumpkin ash (Fraxinus profunda), swamp tupelo (Nyssa sylvatica), bald cypress (Taxodium distichum), and red maple (Acer rubrum) are present. Other trees are mixed in to some degree, usually in the shallo wer areas or edges of the swamp. These include cabbage palm (Sabal palmetto), swamp laurel oak (Quercus laurifolia), sweet bay (Magnolia virginiana), sweet gum (Liquidambar styraciflua), American hornbeam (Carpinus caroliniana), and Florida elm (Ulmus Americana var. floridana) . Buttonbush (Cephalanthus occidentalis) is often the only shrub, excep t in the more open forests, where wax myrtle (Myrica cerifera) is also common. A combination of flooding and shade restrict s the diversity of herbaceous plants. The more open, deep-muck swamps may contain an abundance of bamboo vine (Smilax laurifolia). Densely forested mixed swamps ma y have very few herbaceous plants. The major swamp habitats are the crowns of the tall trees, the hollow trunks and branches of older trees, the muck, and the water. Animal species include mud-dwelling earthworms, several kinds of crayfish and sh rimp, several kinds of snails—including the Florida apple snail ( Pomacea paludosa), which is the primary food source for the limpkin (Aramus guarauna) —and numerous insects and their larv ae. The cavities in tree trunks are especially important, because there is little shelter on the ground. Swamp-dwelling birds requiring cavities for ne sting include the wood duck (Aix sponsa), barred owl (Strix varia), great crested flycatcher (Myiarchus crinitus), Carolina chickadee (Parus carolinensis), tufted titmouse (P. bicolor), and prothonotary warbler (Protonotaria citrea). Other tree-dwelling specie s include the gray squirrel (Sciurus carolinensis), flying squirrel (Glaucomys volans), eastern woodrat (Neotoma floridana), cotton mouse (Peromyscus gossypinus), Virginia opossum (Didelphis virginiana), raccoon (Procyon lotor), and various snakes and lizards.

## In the Springs Coast Basin, cypress domes o ccur as isolated swamps in depressions scattered throughout the pine flatwoods co mmunity in south-central Hernando County and central Pasco County. Most of these dom es range between 1 and 100 acres in size. The smaller ones are mostly round to oval a nd are often dome-shaped when viewed from

# 180 Water Quality Assessment Report: Springs Coast



## the side, since the tallest trees grow in the center of the swamp. Some larger domes are open in the middle and contain eith er an open pond or a small marsh. Pond cypress (Taxodium ascendens) are the predominant tree species in the domes. Very dense shrubs usually form a border ar ound the edge that supports much of the plant and animal diversity, and helps to maintain a moist microclimate inside the dome. If shrubs or ground cover are present in the in terior, they usually comprise fetterbush (Lyonia lucida) and Virginia chain fern (Woodwardia virginica). Other hardwoods may also be present around the edge. Soils are nutrient poor and more acidic than in othe r kinds of swamps. Cypress domes have clay hardpans at varying depths, so that they are rather like large, shallow saucers that hold water. So me organic topsoil or sedime nt is usually present on the surface. The domes are isolated hydrologically except at high water, when they overflow through poorly defined channels from one dome to the next. As with other swamps, many domes lose their surface water almost every year during the dry season. During severe droughts, however, the water stored in the soil may also di sappear, subjecting the vegetation to severe drought stress. Cypr ess domes are a fire-adapted community; the bark of pond cypress is much thicker than th at of other cypress species, allowing it to withstand fires. The cypress domes provide valuable habita t for a number of reptile and amphibian species, but have few mammals and no unique bird species. However, they add an important element of diversity to the fl atwoods areas, support a higher density and diversity of animals than the surrounding flatwoods, and are im portant as a refuge for the flatwoods fauna when the pine forests are ha rvested. The dense thicket at the edge is especially valuable habitat, containing much higher densities and diversity of reptiles, amphibians, and birds than either adjacent community. Cypress domes, especially the edge thickets, are an important habitat for white-tailed deer. Othe r animal species found here include the chicken turtle (Deirochelys reticularia), glossy crayfish snake (Regina rigida), and dwarf siren (Pseudobranchus striatus)

F RESHWATER M ARSHES AND P RAIRIES 

## The Springs Coast Basin contains numer ous freshwater marshes and prairies scattered throughout the pine fl atwoods areas, or in low spots on the Brooksville Ridge. These treeless wetlands vary in size from less than an acre to several hundred acres. They occur in areas of permanent shallow wa ter, around lakes, or in areas that flood or burn frequently enough to prevent woody plants from invading. The term wet prairie is used in central and south Florida for very sh allow marshes in the pine flatwoods that are often dry and burn frequently. Soils are made up of sand over limerock—or, in the flatwoods, of varying amounts of organic mu ck over sand, with a clay layer beneath. A single species of tall grass, sedge, or other herb often dominates marshes and wet prairies. The predominance of a particular species often changes with water depth, sometimes producing a series of bands of different vegetation from the edge to the deepest area. In general, the emergent plan ts are more common in areas with shallower

# 181

water, and the floating-leaved and submerged plants are more common in deeper water. Algae comprise the base of the food chain in the marshes and prairies. Many of the basin’s marshes contain nearly pure stands of maidencane (Panicum hemitomon). Other species that may be present— depending on the soil, water depth, and hydroperiod—are pickerelweed (Pontederia cordata), bladderwort (Utricularia spp .), and bluestem (Andropogon spp.). Cordgrass (Spartina bakeri) and swamp hibiscus (Hibiscus grandiflorus) are found in mildly brackish area s near the coast. Cattail (Typha spp.) marsh grows in areas of high fertility, often replacing other forms of marsh in the presence of nutrients from fertilizers or sewage effluent. Some marsh vegetation on the edges of lake s is highly desirable. The deep water parts of the marsh often contain patches of white water lilies (Nymphaea odorata), spatterdock (Nuphar luteum), or thin stands of maidencane (Panicum hemitomon). These provide good habitat for large fish, such as largemouth bass (Micropterus salmoides) and bream (Lepomis macrochirus). The denser marsh vegetation in shallower waters harbors numerous smaller fish, providi ng a nursery area and a habita t that supports an important part of the food chain. Marshes also support many other animals, help remove nutrients from the lake, and trap sediments wa shed from the shore into the lake. Marshes and prairies are habitat for a numb er of broadly adapted aquatic species and a few terrestrial species. Some animals are sp ecifically adapted to this habitat. Species that use marshes include the hispid cotton rat (Sigmodon hispidus), red-winged blackbird (Agelaius phoeniceus), peninsula newt (Notophthalmus viridescens piaropicola), several kinds of frogs, and a number of small fish sp ecies. Insects, crayfish, snails, and other invertebrates are also quite abundant, providing a good food source for wading birds, raptors, and other predators. Marshes that go dry periodically are particularly important feeding habitat for wood storks (Mycteria americana). Other species that use marshes include the sandhill crane (Grus canadensis), American bittern (Botaurus lentiginosus), king rail (Rallus elegans), Florida green water snake (Nerodia floridana), and roundtailed muskrat (Neofiber alleni).

P ONDS 

## Ponds are small bodies of open, nonflowing wa ter. There are thousands of ponds of 5 acres or less in the Springs Coast Basin, and dozens of larger ones. Most were formed by the collapse of solution caves in the unde rground limestone aquifer, while others are shallow depressions that were once part of ancient seas. They are diverse in their sizes, depths, and locations. While many ponds are permanent, some are ephemeral, drying out completely every few years. All ponds are temporary, however , since they eventually fill up with sediment. Pond ecology is influenced by the surrounding upland soils and biological communities. Another important factor is whet her a pond is isolated or part of a drainage system. The most important factor determ ining the diversity a nd species inhabiting a pond is whether it is permanent. The plants around the edges of ponds are mostly swamp, marsh, and wet prairie plants. Some of the submerged marsh plants grow in the open water areas. Pond species include duckweed (Lemna spp. and Spirodela spp. ), water spangles (Salvinia minima),

# 182 Water Quality Assessment Report: Springs Coast



## mosquito fern (Azolla caroliniana), and several kinds of Sagittaria. However, algae are the most important plants in terms of importance to wildlife. No other habitat has such a high value per acre, and the habitat value of ponds increases with their isolation and separation fr om other wetlands. A very significant part of the animal species of an area larger than 2,000 acres may de pend on less than 1 acre of ephemeral, isolated pond. A single, isolated pond may also have great importance as a source of drinking water for some animals, such as doves (Columbina passerina and Zenaida macroura) and nighthawks (Chordeiles minor). Ponds are breeding sites for a number of insects, amphibians, and birds, including toads (Bufo spp. and Scaphiopus holbrookii), tree frogs (Hyla spp.), gopher frogs (Rana capito), and dragonflies.

L AKES 

## The Springs Coast Basin contains several hund red scattered lakes with areas of 5 to 1,000 acres. Like ponds, these large, perm anently flooded bodies of nonflowing, open water were formed through the collapse of solu tion caves in the limestone aquifer, or are shallow depressions that once formed on an an cient sea floor. Factors influencing the ecology of lakes include size, depth, type of bottom, water quality, water level fluctuation, water inflow and outflow, a nd adjacent wetland and upland ecosystems. The swamps and marshes that are often found on the edges of a lake’s open water area are ecologically important. They are ge nerally more biologica lly productive than open water, supplying small fish, insects, cr ayfish, amphibians, and other small animals that provide an abundant food source for the larg er fish and predators in the open water. Wetlands also serve as nursery areas for some open water species, remove excess nutrients and other pollutant s before they enter the lake, and buffer wave action. Marsh and swamp plant species, discu ssed earlier, are commonly found on the margins of lakes. Plants in the open wate r areas are dominated by single-celled algae, mostly diatoms and green algae. Animal species found in or near lakes incl ude numerous birds, fish, reptiles, and amphibians.

## Coastal areas of the Springs Coast Basin contain many springs. These result from rain falling on inland areas; the water drai ns underground through sinkholes and other channels and fissures in the porous limestone rock, reemerging at the land surface. The largest springs in the basin are Crystal River, Chassahowitzka, Homosassa, and Weeki Wachee, which form the headwaters of large coastal rivers that flow to the Gulf of Mexico. Many smaller springs are also present. Springs provide permanent base flow to ri vers and streams in the basin. The water temperature remains nearly constant year round, and the water itsel f is very clear, nonacidic, and high in dissolved so lids such as calcium carbonate. Spring-connected streams have a divers e and productive year -round aquatic plant community. In addition, because they never st op flowing, they provide important refuges during droughts for aquatic animal species.

### Water Quality Assessment Report: Springs Coast 

# 183

The plant species along spring runs and spri ng-fed rivers usually consist of mixed swamp on shore and freshwater marsh in some scattered, shallow water areas. In some places, hammock forests reach the stream banks. The submerged plants on the stream bottom, however, are markedly different. There are abundant quantities of eelgrass (Vallisneria americana) and arrowhead ( Sagittaria) . Of equal or greater importance are the diatoms and filamentous algae that are att ached to these plants and to everything else on the stream. The submerged plants and algae provide dense c over and a productive foundation for the food chain. Large numbers of aquatic snails support pred ators such as the loggerhead musk turtle (Sternotherus minor minor) and limpkin (Aramus guarauna). The latter feeds mainly on the Florida apple snail (Pomacea paludosa). Other species include marine fish and the endangered West Indian manatee (Trichechus manatus latirostris).

A QUATIC C AVES 

## The thick bed of limerock under the Springs Coast Basin contains many cracks, joints, fissures, and caves filled with water. Underwater or aquatic caves formed when the slightly acidic water disso lved larger passageways over thousands of years. The caves are often interconnected, forming a complex, extensive maze of passageways beneath much of the basin. There are distinct layers in the limerock, each with its own caves, and the different layers are interconn ected by occasional vertical shafts. The Crystal River Formation in the Upper Eocen e Formation contains the most caverns. The water in the caves is generally very clear, with a constant temperature, relatively neutral pH, and high levels of dissolved cal cium carbonate. Considerable currents may be present. A unique and specialized group of animal sp ecies has evolved to take advantage of this unique habitat. The region may have mo re species of blind aquatic cave-dwelling animals than any other region in the world. Invertebrates are predominant. Species found here include McLane’s cave crayfish (Troglocambarus maclanei), pallid cave crayfish (Procambarus pallidus), light-fleeing cave crayfish (P. lucifugus), and Leitheuser’s cave crayfish (P. leitheuseri). At least two amphipods, two isopods, and one shrimp are present. The caves also provi de important habitat for the American eel (Anguilla rostrata) and redeye chub (Notropis harperi).



## Land Cover

The Springs Coast Basin is noteworthy for th e extent and diversity of its remaining natural lands. Table B.1 provides comparisons of current and historical acreages for the major types of land cover in the basin. Table B.2 lists the major conservation areas, including their total acreages, locations, and managing entities. Of the 21 most-endangered ecosystems in th e United States, 6 are found in the basin. Xeric uplands original ly accounted for about 40 percent of the basin’s total land area. The longleaf pine–turkey oak sandhill community has been reduced to only 15 percent of its historical range on the Gulf Coastal Plain, while Florida scrub has been eliminated from 65 to 75 percent of its original st atewide range. Sandhill vegetation was the

# 184 Water Quality Assessment Report: Springs Coast



## hallmark natural community of the Brooksville Ri dge. It is characteristic of the deep, well-drained sands that distinguish the ri dge and impart the very high ground water recharge rates. The permeability of these sa nds also makes the local ground water highly susceptible to contamination. The coniferous (longleaf pine) and broadlea f (hammock) forests of the southeastern United States are among the most biologically valuable on earth. They are also highly endangered. Of all the communities in the basi n, pine flatwoods has been most severely reduced by development. Of this commun ity’s historical coverage, only 16,700 acres remain—or about 20 percent. The upland hardwood community that distinguishes the biologically rich and cultural ly significant Annutteliga Hammock has been reduced to 50 percent of its historical coverage. Most of the original expanse of hardwood forest associated with the Annutteliga system has been lost to development and limerock mining. Unfortunately, much of the remaini ng “hammock” consists of small fragments that retain little of their original habitat value. Southern forested wetlands are represented by a spectacular, unbroken expanse of hydric hammock along the basin’s Gulf Coast shoreline. Although estimates of wetland area for the Springs Coast Basin vary, we tlands account generally for around 25 percent of the basin. Wetlands have fared much be tter than uplands, because the majority of wetland acreage in the basin occu rs as large, continuous systems aligned along the coast. These have not been as susceptible to destruction through land development as the relatively small, isolated wetlands that charact erize large portions of other basins in the

state. Cave and karst systems consist of a unique network of first-magnitude springs and spring-fed rivers. Another land cover type, c oastal communities, comprises one of the most pristine and productive es tuarine systems in Florida. Patterns of public land ownership can help to explain the eff ective protection of wetlands, relative to uplands, in the Springs Coast Basin. Of the 194,500 acres dedicated to conservation, approximately 141,350 acres are sandwiched betw een the Gulf of Mexico and U.S. Highway 19. This amounts to 73 percent of conservation lands in the basin. Three of the four large conservation tracts located inland of the coast (Citrus, Serenova, and Starkey) lie on the basin’s boundary, with large portions extending into adjoining basins.

Conservation Priorities

A SWFWMD study of the remaining natural lands in the basin, using a geographic information system (GIS) analysis, asse ssed the relative importance of proposed acquisitions and identified other potential sites. The highest priority for habitat protection is the coastal lands at the northern end of the basin (extending from the Homosassa Rive r northward to the basin boundary). These connect the basin’s coastal systems with th e Big Bend coastline, creating a continuous swath of core habitat covering nearly 1.2 million acres. Although the vast majority of the core area lies outside the SWFWMD’s boundari es, maintaining connectivity within this vast area would help to ensu re the long-term integrity of the basin’s network of conservation lands.

### Water Quality Assessment Report: Springs Coast 

# 185

The second priority is addressing the gap in public ownership north of the Weeki Wachee River and maintaining connectivity with the Citrus Tract by protecting the Annutteliga Hammock. The latter would also protect the remaining remnants of the hammock vegetation that once distingui shed this region of Florida. The protection of these tracts would preserve the overall size of the protected core habitat along the coastline by maintaining the ex isting contiguity in that system. It would also maintain the existing connectivity between the coastal core and the core habitats provided by the Citrus Tract (the Withlacooc hee State Forest) and the Big Bend coastline north of the basin, and prevent the loss of valuable coastal ha bitat at the southern end of the Weekiwachee Preserve. The latter provides habitat for a population of the threatened Florida black bear and other imperiled species , and also helps to buffer the Weekiwachee Preserve from the intensive development th at has consumed the coastal area in the southern reaches of the basin. Another ecologically important area with a high priority for protection is westcentral Pasco County, east of Port Richey fr om the Starkey Wilderness Preserve toward the Weekiwachee Preserve.

Historical land cover was extrapolated by assigning each soil type to the general land cover category most likely to occur on that soil type. Disturbances associated with mining activities and other development that pr edated the soil surveys precluded the infe rence of historical land cover over portions of the basin; this accounts for the acreag e listed as disturbed under historical coverage.

Appendix C: Information on Reasonable Assurance

TO: Interested Parties

FROM: Mimi Drew, Director Division of Water Facilities

DATE: September 2002

SUBJECT: Guidance for Developmen t of Documentation To Provide Reasonable Assurance that Proposed Pollu tion Control Mechanisms Will Result in the Restoration of Designated Uses in Impaired Waters

The purpose of this memo is to describe the types of information that should be considered, and subsequently documented, wh en evaluating whether there is sufficient reasonable assurance that:

Proposed pollution control mechanisms (typically described in watershed management or restoration plans) addre ssing impaired waters will result in the attainment of applicable water quality st andards (designated uses) at a clearly defined point in the future, and

Reasonable progress towards restoration of designated uses will be made by the time the next 303(d) list of impaired waters is due to be submitted to the EPA.

There are many site-specific issues rela ted to determining whether reasonable assurance has been provided. Accordingly, this document describes the elements or issues that should be considered when evaluating a submittal or when documenting the basis for the Department’s decision, rather than attempting to establis h specific criteria on what constitutes reasonable assurance. It should be noted that the term “reas onable assurance” is used throughout many Department programs and rules, and this guidance specifically addresses the issues related to the “reasonabl e assurance” provided by proposed pollution control mechanisms. This guidance should not be us ed to evaluate the meaning of reasonable assurance in other contexts, par ticularly in permitting decisions.



## Background

The Impaired Surface Waters Rule (IWR), Rule 62-303, F.A.C. (Identification of Impaired Surface Waters), establishes a formal mechanism for identifying surface waters in Florida that are impaired (do not meet applicable water qua lity standards) by pollutants. Most waters that are verified as being impaired by a pollutant will be listed on

# 188 Water Quality Assessment Report: Springs Coast



## the state’s 303(d) list purs uant to the Florida Watershe d Restoration Act (FWRA) and Section 303(d) of the Clean Water Act. Once listed, Total Maximum Daily Loads (TMDLs) will be developed for the pollutants causing the impairment of the listed waters. However, as required by the FWRA, the Department will evaluate whether existing or proposed pollution control mechanisms will effectively address the impairment before placing a water on the stat e’s Verified List. If the Department can document there is reasonable assurance that the impairment will be effectively addressed by the control measure, then the water will not be listed on the final Verified List (other impaired waters that will not be listed in clude waters with TMDLs and waters impaired by pollution).



## Current Rule Text Relating to Evaluati on of Pollution Co ntrol Mechanisms

The rule text addressing the evaluation of proposed pollution control mechanisms is as follows:

Section 62-303.600, Evaluation of Pollution Control Mechanisms



## Upon determining that a waterbody is im paired, the Department shall evaluate whether existing or proposed technol ogy-based effluent limitations and other pollution control programs under local, state, or federal authority are sufficient to result in the attainment of a pplicable water qua lity standards.

If, as a result of the factors set forth in (1), the waterbody segment is expected to attain water quality standards in the futu re and is expected to make reasonable progress towards attainment of water qual ity standards by the time the next 303(d) list is scheduled to be submitted to EPA, the segment shall not be listed on the Verified List. The Department shall document the basis for its decision, noting any proposed pollution control mechanisms and expected improvements in water quality that provide reasonable assuran ce that the waterbody segment will attain applicable water qu ality standards.



## Responsible Parties for Reason able Assurance Demonstration

It is ultimately the Department’s responsib ility to assure adequate documentation in the administrative record whenever the De partment decides to not list an impaired waterbody segment for a given pollutant. This documentation will be very important because the Verified Lists will be adopted by Order of the Secretary and third parties will be provided an opportunity to challenge, via an administrative hearing, all listing decisions (both those listing a wa ter and those to not list a wa ter for a given pollutant). However, the Department expects that local st akeholders will often offer to prepare the necessary documentation to demonstrate re asonable assurance th at proposed control mechanisms will restore a given waterbody. The Department will provide guidance to stakeholders on what information is needed and how it should be submitted.

### Water Quality Assessment Report: Springs Coast 

# 189

Time Frame for Development of Documentation

The Department plans to prepare basin-sp ecific Verified Lists as part of its watershed management cycle, which rotates th rough all of the state’ s basins over a fiveyear, five-phased cycle 1 

## . During the first phase of the cycle, the Department will assess water quality in the basin and prepare a dr aft Planning List of potentially impaired waters. The Department and interested part ies will then have approximately one year (Phase 2) to monitor waters on the pla nning list and prepare documentation, as appropriate, to provide reasonable assurance th at impaired waters will be restored. The Department will review submittals from interested parties during Phase 2, before adopting the Verified List for the basin cont aining the waterbody segment in question.



## What It Means To Be Under Local, State, or Federal Authority

Both the FWRA and the IWR require th at the pollution control programs under consideration be “under local, state, or federal authority.” A pollution control program will be considered "under local, state, or federa l authority" if the program is subject to or required by a local ordinance, state statute or rule, or federal stat ute or regulation. Programs will also be considered under local, state, or federal authority if they are subject to a written agreement, signed by both local stakeholders and at least one governmental entity, that includes measurable goals, performance criteria, benchmarks, and back-up corrective actions to assure th e further progress of the program. It is important to note that these written agreements do not need to be enforceable for nonregulated nonpoint sources. Many nonpoint sources are currently outside of the regulatory pr ograms of EPA, the Department, and the water management di stricts, and reducti ons at these nonpoint sources will be voluntary. In fact, pollu tion control mechanisms for these nonpoint sources would be voluntary even if a TMDL we re developed. As such, these agreements may provide the same level of reasonable assurance that can be provided for a TMDL implementation plan as long as they maintain the Department’s enforcement capability over all point sources involved.



## Time Frame for Attaining Water Quality Standards

The FWRA and the IWR do not establish a specific time limit by which waters must attain applicable water quality standards or designated uses. However, the pollution control mechanisms or watershed restoration pl an must provide reasonable assurance that designated uses will be met at some time in the future . As such, the documentation submitted to the Department must provide a specific date by which time designated uses are expected to be restored. In cases where designated uses will not be met for many years, the documentation should also provide justification as to why the specified time is needed to restore designated uses.

1 Federal regulations currently call for state 303(d) lists every tw o years, but Florida plan s to submit annual updates based on the basin-specific Verified Lists.

# 190 Water Quality Assessment Report: Springs Coast



## Parameter-Specific Nature of Demonstration

For the Department not to place an impaire d waterbody segment on the Verified List, reasonable assurance must be provided for each pollutant that has been documented to be causing impairment of the waterbody segment. However, some entities, including the Department, may want to provide reasona ble assurance addressing only selected pollutants, which could result in the Department not listi ng the waterbody segment for those pollutants, but still listing it for othe rs. In this event, TMDLs will only be developed for the remaining listed pollutants.



## Information To Consider and Docu ment when Assessing Reasonable Assurance in the IWR

To provide reasonable assurance that existing or proposed pollution control mechanisms will restore designated uses, the following information should be evaluated and documented for the Administrative Record:

A Description of the Impaired Water —name of the water listed on the Verified List, the location of the waterbody a nd watershed, the watershed/8-digit cataloging unit code, the NHD identifier (whe n they become available), the type (lake, stream, or estuary) of water, the water use classification, the designated use not being attained, the length (miles) or area (acres) of impaired area, the pollutant(s) of concern (those identifie d as causing or contributing to the impairment), and the suspected or docume nted source(s) of the pollutant(s) of

concern.

A Description of the Water Qua lity or Aquatic Ecological Goals —a description of the water quality–based targets or aquatic ecological goals (both interim and final) that have been established for the polluta nt(s) of concern, the averaging period for any numeric water quality goals, a discussion of how these goals will result in the restoration of the waterbody’s impaired designated uses, a schedule indicating when interim and final targets are expect ed to be met, and a description of procedures (with thresholds) to determ ine whether additiona l (backup) corrective actions are needed.

A Description of the Proposed Man agement Actions To Be Undertaken —names of the responsible participating entities (government, private, others), a summary and list of existing or proposed management activities designed to restore water quality, the geographic scope of a ny proposed management activities, documentation of the estimated pollutant load reduction and other benefits anticipated from implementation of indi vidual management actions, copies of written agreements committing participants to the management actions, a discussion on how future growth and new sources will be addressed, confirmed sources of funding, an implementation sc hedule (including interim milestones and

## Water Quality–Based Targets and Aquatic Ecological Goals

Some of the most important elements liste d above are the requirements to provide water quality–based targets or aquatic ecological goals and a discussion on how resultant pollutant(s) reduction targets/goals will result in restoration of designated uses. Some people have expressed concern about these ta rgets because they e quate a water quality– based restoration target with a TMDL (thus assuming a “Catch 22” that a TMDL is needed to make a demonstration that a TMDL is not needed). However, as is also the case for TMDLs, water quality–based targets can take many forms, and need not be a result of a complex hydrodyna mic/water quality model. In some cases, there may be sufficient hi storical data (pal eolimnological data, loadings from periods predating the impairmen t, or baseline data for Outstanding Florida
Waters 2 

## , for example) that could be used to dete rmine an appropriate water quality target. In other cases, simplified modeling (incl uding regression analysis) may allow for conservative estimates of the assimilative capacity that could then be used as the basis for restoration goals. And, finally, a water qual ity target may have been developed that would be scientifically equiva lent to (or act as the basis for) a TMDL, but the target has not been administratively adopted as a TM DL. In each of these cases, a sound water quality target could be used to evalua te whether the proposed pollution control mechanisms will sufficiently reduce loadings to meet the assimilative capacity of the water in question and result in at tainment of designated uses.

2 Baseline data would be data for the year prior to designation of the OFW.

## Interim Targets

Because it will usually take many years to restore fully the designated uses of an impaired water, interim water quality targets will often be needed to measure whether reasonable progress is being made towards the restoration of designated uses. Examples of such interim targets are provided in the last section of this docum ent, but site-specific measures are also encouraged.



## Averaging Periods for Water Quality Targets

While the averaging period for water qualit y–based targets should be consistent with how the underlying standard is expressed, they can often be expre ssed in a variety of ways and need not be expressed as “daily lo ads.” Annual averages or medians are often appropriate for some parameters, but shorte r-term (seasonal, for example) averages maybe necessary if the impairment is limited to specific seasons or parts of the year. Multiyear averages may be appropriate in limited circumstances where there is naturally high variation of the wate r quality target.



## Estimates of Pollutant Reductio ns from Restoration Actions

It will often be difficult to estimate precisely the pollutant reductions that will result from specific restoration activities. This is particularly true for the implementation of best management practices (BMPs). Howeve r, to provide reasonable assurance that a BMP or other restoration action will reduce loadings of the po llutant of concern to a level that will restore the water’s designated uses, documentation should address how the reductions were calculated, in cluding providing documented values from the scientific literature for reductions attri buted to similar management actions. If the expected reductions are expressed as a range, the midpoint of the range should be used as the basis for estimating reductions, unless documenta tion is provided supporting the use of different removal efficiencies in this specific application.



## New Sources/Growth

Another key element is the discussion on how future growth and new sources will be addressed. Restoration goals mu st address possible increased loadings of the pollutant of concern that are anticipated due to population growth or land use changes in contributing watersheds, both from point and nonpoint sources. This will be particularly important for waters impaired by nutrients, given that so many Florida watersheds are faced with continuing urban, residential, and agricultura l development that results in increased nutrient loading from stor mwater, septic tanks, and wastewater discharges.



## Examples of Reasonable Progress

The determination of whether there will be reasonable progress towards attainment of water quality standards will be very site- and pollutant-specific. Documentation

### Water Quality Assessment Report: Springs Coast 

# 193

should be provided supporting specific progre ss towards restoration of the designated uses of the impaired water. Possible exampl es of reasonable progre ss include, but are not limited to the following:

• A written commitment to implement controls reducing loadings within a specified time frame from watershed stakeholders representing at least 50 percent of the anthropogenic load of the pollutant(s) of concern;

• Evidence of at least a 10 percent reducti on (or alternatively, a percent reduction consistent with meeting the water quality target by the specified date) in annual anthropogenic loading of the pollutant(s) of concern;

• Evidence of at least a 10 percent decreas e (or alternatively, a percent decrease consistent with meeting the water quality ta rget by the specified date) in the annual average concentration of the polluta nt(s) of concern in the water;

• Bioassessment results showing there has been an improvement in the health of the biological community of the water, as meas ured by bioassessment procedures similar to those used to determine impairment and conducted in si milar conditions; or

• Adoption of a local ordinance that specifica lly provides water quality goals, restricts growth or loads tied to the pollutant(s ) of concern, and provides an enforcement option if the proposed management measur e(s) are not implemented as required.

Reasonable progress must be made by the ti me the next 303(d) list is due to be submitted to EPA, which is currently every two years. EPA has contemplated changing the listing cycle to every four or five y ears, and the IWR was specifically worded to allow a longer time frame for requiring reas onable progress in the event that the listing cycle changes.



## Long-Term Requirements

If at any time the Department determines that reasonable assu rance and reasonable progress are not being met, the order adopti ng the Verified List will be amended to include the waterbody on the Ve rified List for the pollutant(s) in question. Additional reasonable progress must be made each time a waterbody is considered for listing under Rule 62-303, F.A.C. (every five years)

# Appendix D: Methodology fo r Determining Impairment Based on the Impaired Sur face Waters Rule

The Impaired Surface Waters Rule

To identify impaired waters in each of the state’s river basins, the Florida Department of Environmental Protection (Department) evaluates water quality data using the science-based methodology in the Identifi cation of Impaired Surface Waters Rule (IWR) (Rule 62-303, Florida Administrative Co de [F.A.C.]). The rule establishes specific criteria and thresholds for impairment, in addition to data sufficiency and data quality requirements. The methodology describe d in the rule is based on a statistical approach designed to provide greater confid ence that the outcome of the water quality assessment is correct. The complete text of the IWR is available at http://www.dep.state.fl.us/lega l/Rules/shared/ 62-303/62-303.pdf. As part of the watershed management appr oach, for each river ba sin in the state the Department will follow the methodology in Section 62-303.300, F.A.C., to develop a Planning List of potentially impaired wate rs to be assessed under Subsections 403.067(2) and (3), Florida Statutes (F.S.). The methodology for developing the Planning List includes an evaluation of aquatic life use support, primary contact and recreational use support, fish and shellfish consumption use support, drinking water use support, and protection of human health. Data older than 10 years cannot be used to evaluate water quality criteria exceedances for the Planni ng List. As required by Subsection 403.067(2), F.S., the Planning List will not be used to administer or implement any regulatory program, and is submitted to the U.S. Environmental Protection Agency (EPA) for informational purposes only. After further assessment, using the me thodology in Part III, Section 62-303.400, F.A.C., the Department will determine if wa ters on the Planning List are, in fact, impaired and if the impairment is caused by pollutant discharges. These waters are placed on a Verified List. The criteria for the Verified List are more stringent than those for the Planning List. Data older than 7.5 year s should not be used to verify impairment. The Verified List will be adopted by Secr etarial Order and forwarded to the EPA for approval as Florida’s Section 303(d) list of impaired waters. The Department will develop TMDLs for these waters under Subsection 403.067(4), F.S.



## Attainment of Designated Use(s)

While the designated uses of a given waterbody are established using the surface water quality classification system described pr eviously, it is important to note that the EPA uses slightly different terminology in its description of designated uses. Because the Department is required to provide use attain ment status for both the state’s 305(b) report and the state’s 303(d) list of impaired wa ters, the Department uses EPA terminology when assessing waters for use attainment. The water quality evaluations and decision processes for listing impaired waters that ar e defined in Florida’s IWR are based on the following designated use attainment categories:

## Sources of Data

The Department’s assessment of water qua lity for each basin statewide includes an analysis of quantitative data from a vari ety of sources, many of which are readily available to the public. These sources in clude the EPA’s Legacy and Modernized STO rage and RET rieval (STORET) Databases, the U. S. Geological Survey (USGS), the Department, the Florida Department of Hea lth (FDOH), the water management districts, local governments, and volunteer monitoring groups. Historically, the Department carried out statewide water quality assessments using data available in the EPA’s Legacy STORET Database; STORET makes up approximately 60 percent of the statewide data used in the IWR assessment. The Legacy STORET dataset is a repository of da ta collected and uploaded by numerous organizations through 1999. The Legacy STORET Database can be accessed at http://www.dep.state.fl.us/water/storet/index.htm. In 2000, the EPA created a modernized version of STORET that included new features designed to address da ta quality assurance/ quality control concerns (see the new STORET Web site at http:// www.epa.gov/storet/. However, because of software difficulties associated with batch uploading of data to Modernized STORET, the data being uploaded to the national repository d ecreased dramatically, and lingering problems have temporarily reduced STORET’s importance as a statewide data source. It houses only about 5 percent of th e statewide IWR Database. Approximately 35 percent of the data used in the IWR assessment was provided by individual organizations that for various r easons, such as time constraints or resource limitations, were not able to en ter their data into the nationa l database. The organizations providing the largest datasets in clude the South Florida, Sout hwest Florida, and St. Johns River Water Management Distri cts; the USGS; and the University of Florida LakeWatch volunteer monitoring group. Severa l of these databases are read ily available to the public

## via the Internet: the South Florid a Water Management District at http://www.envirobase.usgs.gov/, the USGS at http://water.usgs.gov/, and LakeWatch at http://lakewatch.ifas.ufl.edu/. The Department created the IWR Database in 2002 to evaluate data simultaneously in accordance with the IWR methodology for every basin in the state, based on the appropriate data “window.” For the Verifi ed List assessment, the window is 7.5 years (for the IWR Database), and the Planni ng List assessment window is 10 years. Table D.2 shows the periods of record for the Veri fied and Planning Lists for the 5 basin

groups. The evaluation of water quality in the state’s basins also includes some qualitative information. These sources are described in the Water Quality Status Reports and Water Quality Assessment Reports for each basin.

Note: Typically, a 10-year data record is used for the development of the Planning Lists, and a 7.5- year record is used for the Verified Lists.



## Methodology

To determine the status of surface water qualit y in individual river basins in Florida, three categories of data—chemistry data, biological data, and fish consumption advisories—were evaluated to determine pot ential impairments for the four designated use attainment categories discussed earlier: aquatic life, primary contact and recreation, fish and shellfish consumption, drinking wa ter use, and protection of human health.

Aquatic Life Based Attainment

The IWR follows the principle of independe nt applicability. A waterbody is listed for potential impairment of aquatic life use support based on exceedances of any one of four types of water quality indi cators (numeric water quality criteria, nutrient thresholds, biological thresholds, and toxicity data).

### Water Quality Assessment Report: Springs Coast 

# 197

E XCEEDANCES OF N UMERIC W ATER Q UALITY C RITERIA 

## The chemistry data from STORET used in evaluating impairment were also used for preparing the state’s 305(b) report. Only ambient surface water quality stations were included in the assessment of impairment. Wa ter quality information from point sources or wells was excluded. Monito ring stations were classified as one of five waterbody types—spring, stream, lake, estuary, or black water—based on criter ia described in the latest 305(b) report. The assessmen ts included the following parameters:

Metals Arsenic, aluminum, cadmium, chromium VI, chromium III, copper, iron, lead, mercury, nickel, selenium, silver, thallium, and zinc

Nutrients Chlorophyll a for streams and estuaries, and Trophic State Index (TSI) (chlorophyll a, total nitrogen, and total phosphorus) for lakes

Conventionals Dissolved oxygen (DO), fecal coliform, total coliform, pH, unionized ammonia

The requirements for placing waters on the Planning List include d a minimum of 10 temporally independent samples from th e 10-year period of record shown in Table D.2, unless there were 3 exceedances of water qua lity or 1 exceedance of an acute toxicity criterion in a 3-year period. The screeni ng methodology for the Verified List requires at least 20 samples from the last 5 years pr eceding the Planning List assessment. An exceedance, meaning that water quality criteria or standards are not met, is recorded any time the criterion is exceeded by any amount . An exceedance for DO, however, means that a waterbody does not meet the DO criterion , rather than an actual exceedance of the criterion. To determine if a waterbody should be placed on the Planning List for each parameter, the chemical data were analyzed using a computer program written to assess the data, based on criteria established in the IWR, with two exceptions . First, unionized ammonia data were not analyzed by the program, but rather w ith an Excel spreadsheet. Second, because the full complexity of the pH criterion could not be programmed, the incomplete listings for pH are not included. They will be further examined while additional data are collected during Phase 2 of the watershed management cycle. Data analysis and statistical summaries of waterbody identification numbers (WBIDs), waterbody types, and parameters obtained fr om the STORET Database were conducted using Access, SAS statistical software, a nd ArcView geographic information system (GIS) applications The data for metals and conventional para meters were compared with the state surface water quality criteria in Section 62-302.530, F.A.C. (IWR). The rule contains a table of sample numbers versus exceedan ces. A waterbody was placed on the Planning List if there was at least 80 percent confiden ce that the actual criteria exceedance rate was

# 198 Water Quality Assessment Report: Springs Coast



## greater than or equal to 10 percent. To be placed on the Verified List, at least a 90 percent confidence rate was required.

E XCEEDANCES OF N UTRIENT T HRESHOLDS 

## The state currently has a narra tive nutrient criterion instead of a numeric value for nutrient thresholds. The narrative criterion states, “In no case shall nutrient concentrations of a body of wa ter be altered so as to cau se an imbalance in natural populations of aquatic flora or fauna.” The IWR provides an interpretation of the narrative nutrient crite rion. In general, the TSI and the annual mean chlorophyll a values are the primary means for assessing whethe r a waterbody should be assessed further for nutrient impairment. The rule also considers other information th at might indicate an imbalance in flora or fauna due to nutrient enrichment, such as algal blooms, excessive macrophyte growth, a decrease in the distribution (e ither in density or aerial c overage) of seagrasses or other submerged aquatic vegetation, changes in al gal species richness, and excessive diel oxygen swings. Potential nutrient impairment was evalua ted by calculating annual mean chlorophyll

a values for estuaries and streams and the TSI for lakes. For lakes, the TSI was calculated using chlorophyll a , total phosphorus, and total nitr ogen measurements. Direct evidence of imbalances of flora and fauna in waterbodies was also considered in the evaluation of nutrient impairments. In estuarine areas, a water was considered nutrient enriched if the annual mean chlorophyll a values were greater than 11 micrograms per liter ( μ g/L), or if annual mean chlorophyll a values increased by more than 50 percen t over historical values for at least two consecutive years. For streams, a wate r was considered nutri ent enriched if the annual mean chlorophyll a values were greater than 20 μ g/L, or if the annual mean increased by more than 50 percent over hist orical values for at least two consecutive

years. A lake with a mean color greater than 40 platinum cobalt units (PCUs) was considered nutrient enriched if the annual mean TSI exceeded 60. A lake with a mean color less than or equal to 40 PCUs was considered nutrient enriched if the annual mean TSI exceeded 40. In addition, a lake was cons idered nutrient enriched if there was an increase in TSI over the 1989 to 2000 period, or if TSI measurements were 10 units higher than historical values.

E XCEEDANCES OF B IOLOGICAL T HRESHOLDS 

## Bioassessments were carried out for streams, lakes, canals, and rivers using the IWR as guidance and following the Department ’s standard operating procedures, which provide definitions and specific methods for th e generation and analysis of bioassessment data. These are referenced in the individua l bioassessment data tabl es contained in the Status Reports. The purpose behind usi ng a bioassessment methodology in surface water characterizations is that bi ological components of the envi ronment manifest long-term water quality conditions and thus provide a bette r indication of a wate rbody’s true health than discrete chemical or physical measuremen ts alone. Similar to water quality criteria,

### Water Quality Assessment Report: Springs Coast 

# 199

bioassessment methods involve the identific ation of a biological reference condition, based on data from unimpaired or least impacted waters in a given region. For the Planning and Verified List assessm ents, the reference condition data were used to establish expected sc ores, ranging from best to wors t, for various measures of community structure and function, such as numbe rs or percentages of particular species or feeding groups. Data on community stru cture and function from waters of unknown quality in the same region as reference waters were compared with the expected scores of metrics to evaluate th eir biological integrity. Metrics (e.g., number of taxa, percent Dipt era, percent filter feeders) were used independently and as an aggr egated group called an index. Indices have advantages over individual metrics in that they can integrat e several related metrics into one score that reflects a wider range of biol ogical variables. A number of bioassessment metrics and indices exist for assessing populations of plan t and animal life, including fish, diatoms (e.g., microscopic algae and unicellular plankt on), and macroinvertebrates (e.g., insects, crayfish, snails, and mussels). Only macroinvertebrate data from ambient si tes in state surface waters were used in the bioassessments analyzed for the Planning and Verified Lists. The data included sites designated as test and background sites for National Pollutant Di scharge Elimination System (NPDES) fifth-year insp ections, but excluded data fr om effluent outfalls from discharging facilities, or data from monitoring sites not cl early established to collect ambient water quality data. Because s ite-specific habitat and physicochemical assessment information (e.g., percent suitable m acroinvertebrate habita t, water velocities, extent of sand or silt smothering, and riparian [Definition: Of, on, or relating to the banks of a natural course of water.] buffer zone widths) was not available at the time of reporting, it was not included. However, this information is instrumental in pinpointing the causes for failed bioassessment metrics and will be included in future reporting. The data used to develop the Planning a nd Verified Lists were obtained from the Department’s Biological Database (SBI O) and the EPA’s STORET Water Quality Database, where it could be substantiated that the data were generated in compliance with the bioassessment standard operating proce dures referenced in the IWR (Section 62- 303.330, F.A.C.). The data from these databases are used w ithout regard to the randomness of sample site selection. For the purposes of the Status Reports, the seasons are defined as follows: winter (1/1–3/31), spring (4/1–6/30), summer (7/1–9/30), and fall (10/1–12/31). Wet seasons are generally spring and summer, a nd dry seasons are fall and winter, although conditions can vary in the state as a whole.

L AKE C ONDITION I NDEX 

## The scoring of the individual metrics of the Lake Condition Index (LCI), except percent Diptera, was performed acco rding to the following formula:

100(B/A) where A = the 95 percentile of the reference population and B = observed value

# 200 Water Quality Assessment Report: Springs Coast



## For percent Diptera, the following formula was used:

100 (100-B)/(100-A) where A = the 95 percen tile of the reference population and B = observed value

An average LCI score was cal culated by averaging the scor es of the six metrics in the method: total number of taxa; total number of taxa belonging to the orders Ephemeroptera, Odonata, and Trichoptera (EOT taxa); percent EOT taxa; Shannon– Wiener Diversity Index score; Hulbert Index score; and percent Dipteran individuals. LCI calculations were only provided for clear lakes (< 20 PCUs). As macroinvertebratebased indices have not been shown to assess colored lakes in Florida accurately (> 20 PCUs), they have been excluded from bioassess ments. A poor or very poor rating based on the average score constituted a failed bioassessment, based on the IWR.

S TREAM C ONDITION I NDEX 

## A total Stream Condition Index (SCI) score was calculated by adding the scores of the seven metrics in the method: total number of taxa; total number of taxa belonging to the orders Ephemeroptera, Plecoptera, and Trichoptera (EPT taxa); percent Chironomid taxa; percent dominant taxa; percent Diptera; pe rcent filter feeders; and Florida Index. A poor or very poor rating based on the total sc ore constituted a failed bioassessment, based on the IWR. The Water Quality Status Reports contain definitions and specific methods for the generation and analysis of bioassessment data.

B IO R ECON 

## To establish an impairment rating based on BioRecon data, three metrics were used: the Florida Index score, total number of taxa, and total number of EPT taxa. If all three metrics failed to meet thresholds, the wate r was deemed “impaired” based on the IWR.

B IOLOGICAL I NTEGRITY S TANDARD 

## Quantitative data, generated through the use of Hester–Dendy arti ficial substrate samplers, were used to calculate Shannon–Wi ener Diversity Index scores for paired background and test sites, as specified in th e Biological Integrity St andard of Subsection 62-302.530(11), F.A.C. One failure of the sta ndard meant that a waterbody segment was listed as potentially impaired.

E VALUATION OF T OXICITY D ATA 

## Although the IWR describes the use of toxicity data for the assessment of aquatic life-based attainment, no ambient toxicity da ta are available for assessment and this metric was not used.

### Water Quality Assessment Report: Springs Coast 

# 201

Primary Contact and Recreation Attainment

For Class I, II, or III waters, a waterbody was potentially impaired if the following criteria were met:

• The waterbody segment did not meet the applicable water quality criteria for bacteriological quality,

• The waterbody segment included a bathing area that was closed by a local health department or county government for more than 1 week or more than once during a calendar year based on b acteriological data,

• The waterbody segment included a bathing ar ea for which a local health department or county government issued closures, advi sories, or warnings totaling 21 days or more during a calendar year based on bacteriological data, or

• The waterbody segment included a bathing area that was closed or had advisories or warnings for more than 12 weeks dur ing a calendar year based on previous bacteriological data or on de rived relationships between bact eria levels and rainfall or flow.

Fish and Shellfish Consumption Attainment

For Class I, II, or III waters, a waterbody wa s potentially impaired if it did not meet the applicable Class II water quality criteria for bacteriological quality, or if a fish consumption advisory had been issued. Fish consumption advisories were based on the FDOH’s “limited consumption” or “no consumption” advisories for surface waters because of high levels of mercury in fish tissue. In addition, for Class II waters, waterbody segments that had been appr oved for shellfish harvesting but were downgraded to a more restrictive classificat ion were listed as potentially impaired.

Drinking Water Attainment and Protection of Human Health

For Class I waters, a waterbody was potenti ally impaired if it did not meet the applicable Class I water quality criteria.202Water Quality Assessment Report: Springs CoastAppendix E: Water Quality Monitoring Stations Used in the Assessment for the Springs CoastBasin, by Planning UnitWBID Waterbody SegmentWaterbodyTypeSTORET Station ID Station Description BD ED# ofObs.Crystal River/King's Bay1341 Crystal River III M1114GBL 1205 CRYSTAL RIVER 1966 1971 11221341 Crystal River III M 112WRD 02310740SARAGASSA CANAL AT CRYSTAL RIVER,FLA.1964 1965 1001341 Crystal River III M 112WRD 02310744KINGS BAY NORTH @ MAGNOLIA CIRCLEAT CRYSTAL R.
