# 7 Water Quality Assessment Report: Indian River Lagoon

# Executive Summary

Indian River Lagoon

The Indian River Lagoon (IRL) ecosystem is a 155-mile-long estuary located along Florida’s east-central coast. The ecosystem begins at Ponce de Leon Inlet near New Smyrna Beach in Volusia County and extends southward to Jupiter Inlet in Palm Beach County. It includes Mosquito Lagoon, Indian River Lagoon (northern, central, and southern parts), Banana River, and the St. Lucie River and Estuary. Within the FloridaDepartment of Environmental Protection’s (Department’s) Total Maximum Daily Load (TMDL) Program, the IRL Group 5 Basin includes the waters and watersheds of Mosquito Lagoon, the northern and central parts of the Indian River Lagoon, and the Banana River only. The IRL
Basin lies in Volusia, Brevard, and Indian River Counties, and it is located within the jurisdiction of the St. Johns River Water Management District (SJRWMD). The IRL Basin does not include the southern part of the Indian River Lagoon or the St. Lucie River and Estuary, which are TMDL Group 2 waters located within the jurisdiction of the South Florida Water Management District. The Water Quality Assessment Report for the IRL Basin is part of the implementation of the Department’s watershed management approach for restoring and protecting water resources and addressing 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 IRL 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 Department 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 an assessment of ground water quality and ground water to surface water interactions in the basin. It discusses priorities for further evaluation, resource priorities, and proposed actions. 

# 9 Water Quality Assessment Report: Indian River Lagoon

# (See Noteworthy in Chapter 1 for a description of the contents of this report, by chapter.)In the IRL Basin, state, federal, regional, and local agencies and organizations are making progress toward identifying problems and improvingwater 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 Indian River Lagoon National Estuary Program, SJRWMD, Brevard County, and the Marine Resources Council (MRC). Not only do stakeholders in the basin share responsibilities in achievingwater quality improvement objectives, they also play a crucial role in providing the Department with important monitoring data and information on management activities. Signifi cant data providers in the basin include SJRWMD, Florida Department of Agriculture and Consumer Services (DACS), MRC, Volusia County, Brevard County, Florida Department of Health, and the Department. During the next few years, further data collection and analysis will be done to establish TMDLs for impaired waters in the IRL 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 68 waterbodies or waterbody segments in the IRL Basin are impaired and require the development of TMDLs. The following summarizes, by planning unit, impairments by waterbody types and the primary pollutants. Planning units are smallerareas in the basin that provide a more detailed geographic basis for identifying and assessing water quality improvement activities. Figure 3.2

and Figures 3.4 through 3.8 (in Chapter 3) depict the results of this

evaluation.

# 13 Water Quality Assessment Report: Indian River Lagoon

# Total Maximum Daily Load Priority Areas

There are 21 high-priority areas for TMDL development in the IRL
Basin. Section 62-303.500, Florida Administrative Code, defines highpriority 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 Clean Water Act and the pollutant has contributed to the decline or extirpation of a federallylisted 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. (Note: There are no high-priority areas in the Mosquito Lagoon Planning Unit.)

# Summary of Ground Water Findings

Due to the signifi cant interaction between ground water and surface water throughout the basin, ground water may influence surface water quality and should be considered in evaluations of sources causing impairments.

Basinwide Observations of Elevated Parameter ConcentrationsThe highest levels of ammonia and ammonia+organic nitrogen in shall ow ground water are found in the Banana River Planning Unit. However, ground water concentrations of these nutrients in all planning units except Mosquito Lagoon are elevated, compared with those for ground water inthe entire SJRWMD. However, these levels are not higher than the medians for typical streams in Florida. Phosphorus is elevated in the surfi cial aquifer throughout much of the basin, based on available data, and is likely due to natural conditions. Phosphorus, ammonia, and organic nitrogen are particularly elevated in the

surfi cial aquifer of the Banana River Planning Unit.

Median concentrations of iron in the surfi cial aquifer wells are elevated in all of the basin’s planning units with data, suggesting that naturally elevated iron in ground water is also a source of elevated iron in surface waters, where ground water to surface water pathways are present.

Banana River Planning Unit
Three estuarine waterbodies (WBIDs 3044A, 3057B, and 3057C)

a re listed as impaired because of low DO. WBID 3044A is a harbor in the Banana River, and WBIDs 3057B and 3057C are segments of the Banana River. Total nitrogen is the causative pollutant for low DO in all

three estuarine waterbodies. In the surfi cial aquifer, median ammonia and ammonia+organic nitrogen concentrations were the highest of all planningunits in the basin. In addition, orthophosphate and phosphorus concentrations were highest in the planning unit’s surfi cial aquifer. The nutrients in ground water and these impaired surface waters may have sources in common, with ground water discharge providing a portion of the nutrient

load to these waters.

Mosquito Lagoon Planning Unit No waterbodies in the planning unit are currently listed as impaired.

Dat a from the surfi cial aquifer indicate that ground water quality is similar to that of the North IRL Planning Unit.

North Indian River Lagoon Planning Unit Three waterbody segments are listed as impaired for low DO (WBIDs

2 963D, 2963F, and 3028); all are classifi ed as estuaries of the Indian River except for Addison Creek (WBID 3028), which is a freshwater stream. In addition, two segments, Indian River above NASA Causeway 

# 15 Water Quality Assessment Report: Indian River Lagoon

# (WBID 2963E) and Indian River above M. Brewer (WBID 2963F) are listed for nutrients (chlorophyll a ). Phosphorus is elevated in general and is several times higher in shallow ground water than it is in surface waters of the planning unit; thus, the ground water contribution of phosphorus

should be considered.

North Central Indian River Lagoon Planning Unit Four estuarine segments in the planning unit (WBIDs 2963B, 3082,

308 5A, and 3098) are impaired by low DO. Ground water is a potential contributing source of nutrients to surface waters in the planning unit and should be considered because of its potential contribution of phosphorus.

South Central Indian River Lagoon Planning Unit Several waterbodies in the planning unit are listed as impaired for low
DO ( WBIDs 3128, 3129A, 3129B, 3135, 3147, 3153, and 3158), and the North Prong Sebastian River (WBID 3128) is listed as impaired by iron. The median phosphorus level in the planning unit’s surfi cial aquifer ismuch higher than the phosphorus in surface waters, so phosphorus contributions by ground water should be considered. While the North Prong Sebastian River (WBID 3128) is listed for iron, naturally elevated iron in surface water is characteristic of the area. Shallow ground water in thevicinity is also high in iron. In addition, human-induced erosion of sediments and other activities in the intensively managed citrus area drained by the North Prong Sebastian River could cause elevated iron concentrations

in the river.

# 20 Water Quality Assessment Report: Indian River Lagoon

# 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 all waters 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 Water Quality Status Report published during Phase 1 of the watershed management cycle provided a Planning List , or preliminary identification, of potentially impaired waterbodies in the Indian River Lagoon (IRL) Basin. A copy of the report can be found at http://www.dep.state.fl .us/ water/tmdl/stat_rep.htm. 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 for which TMDLs must be developed and implemented. It also describes the results of a preliminary ground water quality assessment and discussespriorities 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, 68 waterbodies or waterbody segments

in the IRL 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 the FWRA, Subsection 403.067(4),
Florida Statutes, 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: Indian River Lagoon

# with the FWRA and the 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 IRL 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 potential for impairment, and the need for TMDL development for each waterbody or waterbody segment in the basin. Tables 3.4 through 3.8 in Chapter 3 provide an integrated assessment for the IRL 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 are 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 the IRL Basin. Significant data providers are St. Johns River Water Management District, Florida Department of Agriculture and Consumer Services, Marine Resources Council, Volusia County, Brevard County, Florida Department of Health, and the Department.

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 Strategic Monitoring 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 waters for 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, andpreliminary 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



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

Figure 1.1 shows the order in which the Department’s Central District basins will be evaluated under the watershed management cycle. These groups are identifi ed according to a U.S. Geological Survey classifi cation system using hydrologic unit codes. The Ocklawaha Group 1 Basin was the fi rst basin in the district to undergo a preliminary assessment in 2000. A preliminary assessment of the Middle St. Johns Group 2 Basin was completed in 2001. The Upper St. Johns Group 3 Basin was assessed on a preliminary basis in 2002. Similarly, a preliminary assessment for the Kissimmee Group 4 Basin was initiated in 2003, and the preliminary assessment of the IRL Group 5 Basin was begun in 2004. In 2005, the cycle resumed with the Ocklawaha Group 1 Basin.

# Chapter 2: Basin Overview

Basin Setting

The Indian River Lagoon (IRL) ecosystem is a 155-mile-long estuary located along Florida’s east-central coast. The ecosystem begins at Ponce de Leon Inlet near New Smyrna Beach in Volusia County and extends southward to Jupiter Inlet in Palm Beach County. It includes Mosquito Lagoon, IRL (northern, central, and southern parts), Banana River, and theSt. Lucie River and Estuary. Within the Florida Department of Environmental Protection’s (Department’s) Total Maximum Daily Load (TMDL) Program, the IRL Group 5 Basin includes the waters and watersheds of Mosquito Lagoon, the northern and central parts of the IRL, and the Banana River only. The IRL Basin lies in Volusia, Brevard, and Indian River Counties, and it is located within the jurisdiction of the St. Johns River Water Management District (SJRWMD). The IRL Basin does not include the southern part of the IRL or the St. Lucie River and Estuary, which are TMDL Group 2 waters located within the jurisdiction of the South Florida Water Management District (SFWMD). Figure 2.1 shows the principal geopolitical features in the IRL Basin. The IRL Basin has geomorphic land features that may date back as long ago as 420,000 years (SJRWMD, 1996), shaped by the rise and fall of the sea. The basin’s major waterbodies are 3 elongated saline lagoons: Mosquito Lagoon, IRL (northern and central parts), and the Banana River (IRL lagoon system). These lagoons separate the mainland of Florida from a strip of barrier islands that extend north and south of two unique land features, Cape Canaveral and Merritt Island. The IRL Basin is an important economic and biological resource within Florida. More than 50 percent of the Florida east coast fi sh catch and historically 90 percent of Florida’s clam harvest come from the basin. Clam harvests have declined in recent years (Steward, 2006). The basinis also an important producer of Florida’s Indian River citrus. Biological diversity is high in the basin, with more than 4,000 animal and plant species recorded, including 36 rare and endangered animal species. Space exploration and the military have a prominent presence in the basin. Kennedy Space Center is located on north Merritt Island. The large tracts of land needed by the Space Center for security and facilities resulted in the acquisition of 140,000 acres of beaches, dunes, fl atwoods, wetlands, and marshes for the Merritt Island National Wildlife Refuge. The military maintains bases at Patrick Air Force Base and Cape Canaveral Air Force Base. Much of the industry in the Brevard County portion of the basin provides support for space exploration and military operations.

# Major mainland municipalities are New Smyrna Beach, Titusville, Cocoa, Rockledge, Merritt Island, Melbourne, Palm Bay, Sebastian, and Vero Beach. Major barrier island beachside communities are Cape Canaveral, Cocoa Beach, Satellite Beach, Indian Harbour Beach,
Indialantic, and Melbourne Beach.
Growth in the basin, like much of Florida, has accelerated tremendously since the 1950s. The expansion of tourism, the space industryassociated with space exploration, and agriculture—coupled with improvements in access to the basin and control of mosquitoes—helped fuel growth(Woodward-Clyde Consultants, 1994a). Since 1950, the combined population of Volusia, Brevard, and Indian River Counties has increased from well under 200,000 people to about 1 million people. The population continues to grow and is projected to be about 1.4 million in 2020. The basin also contains Palm Bay, one of the fastest growing cities in the United States. About 160 miles of roadway have been designated as the Indian River Scenic Highway (Florida Department of Transportation, 2005). The scenic route follows a southern loop starting from the Lagoon House on U.S. Highway 1 before looping east on the Wabasso Causeway and then north along State Road A1A.



# Surface Water Resources

Primary surface water resources in the IRL Basin are Mosquito Lagoon, IRL (northern and central parts), and the Banana River. These waters comprise a saline lagoon system (IRL lagoon system) that runs parallel to Florida’s east coast, and separates the mainland from a string of

barrier islands. Figure 2.2 shows the locations of the largest waterbodies inthe IRL Basin. A more detailed discussion in Chapter 3 provides information on each planning unit. Mosquito Lagoon extends from Ponce de Leon Inlet south to a dune ridge located between Mosquito Lagoon and the Banana River. The northern part of Mosquito Lagoon’s watershed drains largely salt marsh and mangrove marsh. The western boundary of Mosquito Lagoon is a poorly

defi ned dune ridge. Mosquito Lagoon is connected to the IRL by the Haulover Canal. South of Haulover Canal, the dune ridge forms part of

northern Merritt Island.

The North to South Central IRL extends from Turnbull Creek south to Indian River County/St. Lucie County. Major cities from which it receives drainage include Titusville, Cocoa, Rockledge, Merritt Island,
Eau Gallie, Melbourne, Sebastian, and Vero Beach. From north to south, major tributaries to the North to South Central IRL include Turnbull Creek, Canaveral Barge Canal, the valley between Ten Mile Ridge and the Atlantic Coastal Ridge, Eau Gallie River (receives drainage from the city of Melbourne), Crane Creek (receives drainage from the cities of Melbourne and Melbourne Village), Turkey Creek (receives drainage from urbanized areas of the city of Palm Bay and agriculture), C-1 and C-54 Canals (flowing from the Upper St. Johns River Basin), Goat Creek, Kid Creek (drains Valkaria Airport and Missile Tracking Annex), Trout Creek, and the North

# and South Prongs of the Sebastian River. It also receives drainage from
canals within the Sebastian River Water Control District, Fellsmere Water
Control District, Vero Lakes Water Control District, Indian River Farms Drainage District, Fellsmere Main Canals, Indian River Farms North,
Main and South Canals, and various stormwater canals. The Banana River is essentially a lagoon with a central channel. It

lies between Merritt Island and the coastal barrier islands. It extends in a

north-south direction from Banana Creek south to the Eau Gallie Causeway. Sykes Creek (a small lagoon system) and Newfound Harbor are the primary tributaries to the Banana River. A description of the basin’s physiographic features and factors affecting the hydrology, hydrodynamics, and water quality of the basin is provided below. A description of surface water classifications and special designations applicable to the basin is also provided.

Physiographic Features The geologic history of the basin has shaped its physical form and

ul timately infl uenced the location of surface water resources. The basin’s surface features were created and shaped by the rise and fall of the sea. Barrier islands that extend north and south of Cape Canaveral and Merritt Island form the eastern boundary of the basin. West Merritt Island may well have formed when sea levels were lower. Rising sea levels eroded the

Merritt Island beach and formed a sandbar offshore to the east. Once sea levels receded, the sandbar was reworked to form the Banana River Lagoonand Cape Canaveral. It is believed that the southern barrier islands developed as sand was moved south from Cape Canaveral. When water levels were higher, plains were formed from erosion by waves and currents. These plains became terraces or fl atlands when the water receded. The terraces in the basin, in order of decreasing elevation,

are the Pamlico and Silver Bluff Terraces. Dunes formed on these terraces parallel to and west of the basin. Higher ridges formed on the dunes. The Atlantic Coastal Ridge formed on the Silver Bluff Terrace, and the Ten Mile and Green Ridges formed on the Pamlico Terrace.

Hydrodynamics, Hydrology, and Water Quality Effects The IRL Basin’s climate is predominantly humid subtropical, with a

d ry season (mid-October to May) and a wet season (June to mid-October) (Knowles, 1995). Average rainfall in the basin ranges from 55 to 60 inches per year, with about 62 percent of the total rain falling from June through October (SJRWMD, 1996). The spatial distribution of rainfall across the basin has been historically variable, with the most rain falling in the Titusville area and the least falling between Palm Bay and Sebastian Inlet
(Knowles, 1995). Rainfall is distributed within the basin in many different forms. The IRL lagoon system receives saltwater inputs from the Atlantic Ocean through inlets. Connections to the Atlantic Ocean, moving north to
south, are limited to Ponce de Leon Inlet, Port Canaveral entrance, Sebastian Inlet, Fort Pierce Inlet, and St. Lucie and Jupiter Inlets, some of which are outside the geographic area discussed in this report. Only Ponce 

# 31 Water Quality Assessment Report: Indian River Lagoon

# de Leon and Jupiter Inlets are natural entrances to the lagoon. Fresh water enters the lagoon system from rainfall, surface water runoff, ground water seepage, and infl ows from tributary streams and drainage canals. Historically, the basin’s drainage pattern consisted of a network of slow, meandering sloughs, creeks, rivers, and wetlands. The basin could

absorb fl oodwaters and slowly release them either as surface water runoff to the lagoon system or as ground water recharge. Discharges into the three coastal lagoons only occurred after large storm events. To the east, the basin’s boundary was—and still is—defi ned by barrier island dune lines. The western boundary was delineated by uplands along the Atlantic Coastal Ridge and Green and Ten Mile Ridges. Settlement of the IRL Basin and surrounding basins in the 1840s led to changes in the hydrology of the IRL lagoon system. In 1916, the lagoon system received drainage from about 572,000 acres (SJRWMD, 2005a).Today it receives drainage from 1.4 million acres. Much of this expansion was due to draining parts of the Lake Okeechobee Basin and Upper St. Johns River Basin for agriculture and development and diverting the
associated waters to the IRL Basin via canals, such as the C-1 and C-54 Canals. The 1916 Drainage Acts of Florida created special taxing districts to promote agriculture and provide fl ood and drainage control. A large part of the drainage works performed from 1916 to 1950 modifi ed almost all natural streams and interconnected lagoons within the IRL Basin through the construction of canals (Woodward-Clyde Consultants, 1994c). In addition, increased impervious surface area within the IRL Basin has contributed to increased stormwater runoff to the IRL lagoon system. All of these factors act to alter the timing and volume of stormwater releases to the lagoon system. It has been estimated that twice as much freshwaterenters the IRL lagoon system compared with 100 years ago (WoodwardClyde Consultants, 1994c). A substantial amount of the stormwater volume is discharged in the fi rst few hours after a storm event. Changes in stream discharge were the greatest south of Melbourne, with the Eau Gallie River, Turkey Creek, Sebastian River, Crane Creek, and Indian River Farms Water Control District Canals experiencing the greatest alterations in fl ow. Stormwater discharges carry large loadings of nutrients, sediments, and other pollutants into the lagoon system and fairly rapidly change salinity near the mouths of streams. Rapid changes in salinity can be detrimental to many marine and estuarine organisms.Additional drainage canals were dug to accommodate urban expansion and mosquito control. Special taxing districts called mosquito control districts were created to address mosquito problems. South ofCape Canaveral, mosquito control districts used ditches and impoundments as mosquito control techniques (Woodward-Clyde Consultants, 1994a). About 75 percent of the basin’s salt marshes, including those in the southern part of the IRL in Martin and St. Lucie Counties, have been impounded for mosquito control, reducing or eliminating their connection with the open waters of the lagoon system. North of Cape Canaveral, a 140-mile network of drainage ditches was dug specifi cally for drainage to control mosquitoes (Woodward-Clyde Consultants, 1994a).

# The construction and dredging of channels affect lagoon hydrodynamics. The Intracoastal Waterway was built to create a deepwater channel for navigation. The channel is maintained to a depth of 12 feet north of Fort Pierce and 10 feet south of Fort Pierce. Dredged material from the channel was often used to create spoil islands. The Intracoastal Waterway extends the entire length of Mosquito Lagoon and is connected

to the Indian River via the Haulover Canal. The Banana River and Port Canaveral are connected to the Indian River by the Canaveral Barge Canal. The Banana River Channel and the Saturn Barge Canal extend the length

of the Banana River. The construction of various causeways over the lagoon system required

fi lling parts of the shoreline at the causeway crossings. The open water area at these locations has been narrowed, which affects overall lagoon system water circulation, which is sluggish and mostly wind-driven. Limited tidal

fl ushing with the Atlantic Ocean and the long, narrow, and shallow nature of the lagoon system further affect water circulation, making the lagoon system particularly vulnerable to the detrimental effects of introduced pollutants.

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)

Figure 2.3 depicts water use classifications and waters with special designations located in the IRL Basin. Large parts of the IRL, Banana River, and Mosquito River are classifi ed as Class II waters for shellfi sh harvesting and propagation, and they are divided into smaller manageable blocks of

shellfi sh harvesting areas. Each area is classifi ed and managed to protectthe public from disease and contamination associated with the consumption of shellfi sh. The harvesting of shellfi sh is an important contributor to the local economy. Potable surface water drinking supplies used in the

basin are located outside its boundaries.

# Special Designations

Outstanding Florida Waters



# The waterbodies listed in Table 2.1 have been given additional protection through designation as Outstanding Florida Waters (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 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.



# Biological Resources

The IRL Basin is biologically unique because of a combination of climatological and physiographical features. It is where the tropical and temperate climate zones meet. Plants and animals found in the basin represent species that prefer a warm tropical climate alongside those that prefer cooler conditions. The long, narrow, north-to-south shape of the basin has helped increase the diversity of the biological communities present. Majordifferences occur in species composition between the northern and southern parts of the basin, and between the open waters of the basin and coastal

areas. Appendix B contains supplementary information on the basin’s imperiled and endangered plants and animals.

# Communities The IRL Basin supports numerous upland, estuarine, marine, and

f reshwater habitats. Habitats range from longleaf pine forest to mangrove swamp. Coastal geology, topography, and latitude are important factors that determine community composition and distribution. Vegetation and land cover were mapped for the entire state by the Florida Fish and Wildlife Conservation Commission (FWC) using 2003 Landsat imagery (Gilbert and Stys, 2004; Stys, Kautz, Reed, Kertis, Kawula, Keller, and Davis, 2004). Vegetation and land cover were grouped into 26 categories of natural and seminatural communities, 1 category for water, and an additional 16 categories of disturbed land cover types.

Table 2.2 lists the common general natural community types found in the IRL Basin as delineated by Gilbert and Stys (2004). Descriptions of each habitat type are contained in Table B.1 in Appendix B. Additionally, unique habitat types exist in the form of spoil islands, impounded marshes, and seagrass beds.

# Uplands 

# Prior to development, the IRL Basin’s upland communities comprised longleaf pine forest, pinelands, and xeric oak scrub maritime forest. The basin’s western side would have been composed of pine forest and scrub oak, which graded into salt marshes in the north and mangrove swamp in the south at the upper edge of the intertidal zone (Woodward-Clyde
Consultants, 1994b). On the eastern or barrier island side of the basin, a change in vegetation occurs as one moves eastward from the maritime

forest to coastal strand and beach dune communities. In the northern
latitudes, live oak (Quercus virginiana) dominates the maritime forest. But approaching the area of Cape Canaveral, live oak is reduced in number as it reaches its southern limit and starts to be replaced by more tropical fl ora, such as gumbo limbo (Bursera simaurba) , wild coffee (Psychotria undata)

, and wild tamarind (Lysiloma latisiliqua)

. The upland communities present on the eastern barrier islands are
maritime hardwood hammock or forest, hardwood hammock, and coastal scrub. Maritime forest generally occurs on old stabilized dunes. Common plant species found in the maritime forest north of Cape Canaveral are live oak, saw palmetto, red bay, southern magnolia, and cabbage palm. South of Cape Canaveral, West Indian species become common. Hardwood hammocks north of Sebastian Inlet occupy an area that is transitional between swamp and upland forest. These communities usually occur as islands or small stands in depressions. South of Sebastian Inlet, and outside the area addressed in this report, tropical hardwood hammocks are the

common hardwood hammock. Coastal xeric oak scrub is the other major upland community found on the barrier islands. Scrub typically occurs on dry and well-drained sand dune areas. Large areas can still be found in the Merritt Island National Wildlife Refuge and on some private lands on Merritt Island. Evergreen oaks, myrtle oak, and Chapman oak dominate the scrub canopy.

Wetlands 

# Both marine/estuarine and freshwater wetland communities are present in the basin. Wetlands play an important role in maintaining water quality. They function as fi lters, removing sediments, nutrients, and other runoffpollutants before they enter the IRL lagoon system. Wetlands also protect the shoreline from erosion by buffering the shoreline from the erosive energy generated by waves from storms or boats.

Prominent marine and estuarine wetland coastal communities are salt marshes and mangrove marshes. Detritus produced in these wetlands is a major food source for aquatic animals. Wading birds forage in the marsh tidal creeks and impounded marshes for small fi sh and insects. Mangrove marshes provide roosting and nesting areas for many different species of wading birds. About 80 percent of the commercially and recreationally important fi sh species spend part of their life cycle in mangrove swamps (Woodward-Clyde Consultants, Marshall McCully & Associates, and Natural Systems Analysts, 1994).

Much of the salt marsh habitat is found on Merritt Island and further north. Mangroves are excluded in the northern part of the basin because 

# 37 Water Quality Assessment Report: Indian River Lagoon

# of periodic winter freezes. Natural berms along many of the basin’s salt

marshes restrict flooding except during high tides, creating what is commonly called high marsh. The effect of this is to limit vegetation to highsalinity-tolerant species. The basin’s salt marshes provide critical habitat for rare and/or imperiled species. The now extinct dusky seaside sparrowutilized salt marshes as habitat. Impoundment of the marshes for mosquito control eliminated the sparrow’s habitat. The threatened Atlantic salt

marsh snake (Nerodia fasciata taeniata) is found almost exclusively in the salt marshes bordering Mosquito Lagoon. Mangrove marshes are dominated by red mangrove, black mangrove,and white mangrove. The distribution of the three species follows a gradient defi ned by water depth and frequency of inundation. Red mangroves inhabit deep water edges while black and white mangroves occur near or above the average high water line. Freshwater wetlands in the basin are predominantly marsh and wet prairie and a variety of mixed and hardwood swamps. These wetlands provide cover, forage, and nesting habitats for birds and other wildlife species. Many crustaceans and fi sh are adapted to the transitional zone

where freshwater and saltwater mix. Most swamp-type wetlands are typically found along rivers, such as the Sebastian River. Prominent trees are red maple, cypress, and laurel oak. The largest area of swamp is Turnbull Hammock bordering Turnbull Creek. The swamp grades into upland hammock at the upper end of the watershed, but at its lower end it is typically blackwater fl oodplain forest or hydric hammock. There are several freshwater marshes in the basin, though most are
small in size, less than fi ve acres (Woodward-Clyde Consultants et al., 1994). Many of those close to the IRL lagoon system are in swales anddepressions between dunes and dune ridges that extend in a linear northto-south direction. They are situated on sandy soils and receive water from either a high ground water table and by the lateral fl ow of water from dunes. The largest marsh of this type is in the Merritt Island National Wildlife Refuge. Wet prairies or flatwood marshes are common wetland types characterized as typically round depressions within poorly drained pineland or

fl atwood communities. In their natural state, these marshes were isolatedfrom other wetlands and surface waters, but, subsequently, ditches constructed to provide drainage have connected them to the surface drainage system (Woodward-Clyde Consultants et al., 1994). This type of marsh can grade into pinelands through poorly drained cabbage palm savannas or
wet prairies.

Seagrasses and Open Water

# Submerged aquatic vegetation (SAV), including seagrasses and macroalgae, comprise an important community type within the IRL lagoon

system. Figure 2.4 displays the distribution of seagrasses at different time periods. There are seven species of seagrass within the lagoon system, with the three most abundant species being turtle grass, manatee grass, and shoal grass. Factors that affect the distribution of SAVs include water 

# 38 Water Quality Assessment Report: Indian River Lagoon

# Figure 2.4: Comparison of Seagrass Distribution in 1943, 1992, and 2003 

# 39 Water Quality Assessment Report: Indian River Lagoon

# depth and clarity as defi ned by the penetration of light, substrate, nutrient concentrations, salinity levels, water temperature, stormwater runoff, and water-based activities on and around the seagrasses. SAVs support the lagoon’s biodiversity in many ways. SAVs help to stabilize bottom sediments, reducing the resuspension of particulate matter and sediments and reducing turbidity in the water column. They also provide cover for juvenile fi sh and wildlife and provide opportunities for foraging for food by larger predators. Communities of algae, small plants, and animals live within the SAVs and attach themselves to the seagrass,
benthic invertebrates, and fi sh. SAV beds support a rich diversity of fi sh and other species and fi sh densities. Seagrasses are a major food source for the West Indian manatee. Juvenile sea turtles also forage on seagrasses. Seagrass coverage in the IRL lagoon system has declined in many areas

since 1943 (Figure 2.4) . Overall, seagrasses declined about 18 percent from the early 1940s to 1992 (Virnstein, 1999). Some areas of the lagoon system have lost very little seagrass; examples are the southern part of the Mosquito Lagoon, northern Banana River, and the north end of the IRL. Generally, seagrasses have done well in areas with limited development or near natural areas (wetlands and uplands). Other more developed areas of the lagoon system have had extensive losses of SAV. Between 1942 and 1992, the stretch of the IRL from the NASA Causeway south to the city of Grant lost about 70 percent of its seagrass acreage (Virnstein, 1999). Parts of the lagoon bottom that are not covered with SAV also provide important habitat. About 65 percent of the IRL lagoon system is open water (Woodward-Clyde Consultants et al., 1994). Bottom types canbe rocky, sandy, or muddy. These bottom types provide important habitat for hard clams, oysters, and blue crabs. Phytoplankton adds to the seagrass-based productivity of the lagoon and is the base of its food web. Phytoplankton and zooplankton provide food for larval spotted sea trout and other economically important fi sh species and adult bay anchovy and

black mullet.

Impounded Marshes 

# The impoundment of coastal marshes was begun in the 1930s as a mechanism to control salt marsh mosquitoes. Management of theimpoundments was generally done by control of water levels during mosquito breeding season. Impounded marshes (about 75 percent of the wetland area of the IRL Basin) were disconnected from the open waters of the lagoon system, thereby prohibiting fish and other aquatic organisms from inhabiting the marshes. Marsh impoundment also prevents the transport of detritus to the lagoon system, limiting an important food source for some aquatic animals. Mangroves are frequently killed through impoundment, thereby removing roosting and rookery habitat for wading birds. Changes in community structure from marsh to mangrove wetland occurred in impoundments south of the city of Melbourne. Since the 1980s, some form of rotational impoundment managementhas been in effect. Rotational impoundment management allows alternating fl ooding and drying cycles. Open Marsh Water Management requires the installation of culverts or other openings allowing for more natural tidal cycles and fl uctuations (SJRWMD, 1996). 

# 40 Water Quality Assessment Report: Indian River Lagoon

# Spoil Islands 

# Spoil islands are created when sediment dredged from the bottom of the IRL is deposited to form large mounds or islands. Dredged sediments are composed of sand, shell, and muck. The construction and regular maintenance of the Intracoastal Waterway and other navigation channels has resulted in a number of spoil islands. Once created, spoil islands are rapidly colonized; unfortunately, most vegetation is exotic. Spoil islands do support a diverse assemblage of fi sh and wildlife. Seagrasses established around the perimeter of the islands increase their biological diversity and utility by providing habitat for juvenile fi sh and other aquatic species.

Important Plants and Animals The IRL ecosystem contains more species of plants and animals than

o ther similar ecosystems in North America. It is estimated to contain more than 2,200 animal species and 2,100 plant species. The eco system’s location along the Atlantic fl yway contributes to its use by a diverse number of bird species. About 125 species of birds breed in the ecosystem while another 170 species winter there. At least 50 wading bird and shore bird mixed nesting areas are present; most are on spoil islands and within mangrove swamps (Woodward-Clyde Consultants et al., 1994). One of the larger rookery areas is Pelican Island in the Pelican Island National Wildlife Refuge. Gilmore (1995) has listed at least 782 species of fish from the eastcentral Florida region, including the IRL ecosystem. He noted that about half the listed species utilized the IRL lagoon system during at least part of their life cycle. The high biodiversity of the IRL ecosystem is helped by its geographic position, stretching across temperate and subtropical climatic zones.Proximity to tropical ocean currents provides stable warm water temperatures with limited seasonal variation, which enhance biodiversity
(Gilmore, 1995).The diversity of aquatic habitats is another factor adding to the diversity of resident and transient species. Some marine animals such as theWest Indian manatee and bottlenose dolphin use the lagoon on a yearround basis. Other marine species use the lagoon seasonally or during migration to other feeding or refuge areas.

Rare, Imperiled, and Endangered Plants and Animals

# The Florida Natural Areas Inventory Database of Element Occurrences (2005) documents the occurrence of 44 state or federally threatened or endangered plant and animal species in the IRL Basin ( Table B.2 in Appendix B). Merritt Island National Wildlife Refuge contains a large number of these threatened and endangered species. Development of the basin with subsequent loss of critical habitat has reduced the number of many of the identifi ed rare and imperiled species. A number of bird species are listed species or considered imperiled. Pelican Island National Wildlife Refuge was created in 1890 to protect the endangered Eastern brown pelicans (Pelecanus occidentalis) . A historic threat to the pelicans was the widespread use of chlorinated pesticides (primarily DDT) in the 1960s and 1970s, though the bird has largely 

# 41 Water Quality Assessment Report: Indian River Lagoon

# recovered. A more recent issue is the entanglement of the birds in fishermen’s lines. The dusky seaside sparrow was at one time an inhabitant ofcoastal marshes, but has become extinct most likely as a result of the construction of impoundments that altered its habitat. The Florida scrub jay (Aphelocoma coerulescens coerulescens) prefers dry, sandy oak scrub habitat, and although this habitat is also desirable for human development, this bird species is still present in the Merritt Island National Wildlife Refuge, Kennedy Space Center, Cape Canaveral Air Force Station, and at scattered locations in Brevard and Volusia Counties (Woodward-Clyde Consultants
et al., 1994). Johnson’s seagrass (Halophila johnsonii) is a rare seagrass found from Sebastian Inlet south (SJRWMD, 1996). Listed as threatened at both the federal and state levels, Johnson’s seagrass is one of seven species of seagrass that grows in the IRL lagoon system. Several other rare or imperiled plant species occur in this basin. Curtiss’ sandgrass (Calamovilfa curtissii) , the sand butterfl y pea (Centrosema arencicola) , sea lavender (Argusia gnaphalodes) , and large-

fl owered rosemary (Conradina grandifl ora) are examples of state-listed species. Curtiss’ sandgrass, the sand butterfl y pea, and large-fl oweredrosemary typically grow in scrub or sandhill habitats. Sea lavender is typically found near beaches, coastal strand, and the outer edge of salt fl ats. Development threatens much of these habitat types throughout the IRL
Basin (NatureServe, 2005). Several rare and imperiled fi sh species have been documented as occurring in the IRL lagoon system. Occurrences of the mangrove rivulus
(Rivulus marmoratus) , opossum pipefi sh (Microphis brachyurus) , mountain

mullet (Agonostomus monticola) , and river goby (Awaous banana) have been documented in the lagoons (NatureServe, 2005). The mangrove rivulus and opossum pipefi sh are listed as species of special concern by the U.S.
Fish and Wildlife Service (NatureServe, 2005). The mountain mullet has been observed in Crane Creek and Mosquito Lagoon, the opossum pipefi sh was recorded in Sebastian Creek, and the river goby was recorded in the
Sebastian River, North Canal, and South Canal. The distribution of the mangrove rivulus parallels the distribution ofred mangroves, and it is considered an indicator of red mangrove community health due to its sensitivity to habitat destruction and toxins (Taylor, Davis, and Turner, 1995). The mangrove rivulus has already disappeared from impounded coastal marshes in the IRL Basin (Taylor, Davis, and
Turner, 1995). Two species of marine turtles, the green turtle (Chelonia mydas mydas) and loggerhead turtle (Caretta caretta) , inhabit the IRL lagoon system. The green turtle is listed as endangered while the loggerhead turtle is listed as threatened at both federal and state levels. The lagoon system provides important habitat for both species in their early development stages. Both turtle species return to the ocean at reproductive maturity. Threats to their viability include collisions with boats and entanglement in fi shing lines. Many sea turtles are also infected with a disease known as fibropapillomatosis, which causes tumor-like growths. 

# 42 Water Quality Assessment Report: Indian River Lagoon

# The population of West Indian manatees that reside in the IRL lagoon system represents about one-third of the Florida population of manatees. During warm weather, manatees are present throughout the lagoon. During cooler weather, they congregate at warm water discharges from power plants, or they migrate south. Boat traffi c is a continual threat to manatees. Many are killed by boats or scarred from contact with propellers. Brevard and Volusia Counties have completed and received approval for manatee protection plans from the FWC and the U.S. Fish

and Wildlife Service.The Atlantic bottlenose dolphin, though not a listed species, is prevalent in the central and southern parts of the IRL. There could be as many as 300 animals residing in the lagoon on a permanent basis while many other dolphins move between the lagoon and Atlantic Ocean. Collisions with boats and fi shing lines are threats to dolphin survival. Additionally, a fungal skin disease called Lobo mycosis affl icts as much as 12 percent of the dolphin population and is another threat to the local population (SJRWMD, 1996).

Commercially and Recreationally Valuable Species 

# Spotted seatrout (Cynoscion nebulosus) , common snook (Centropomus undecimalis) , Atlantic tarpon (Megalops atlanticus) , grouper and snapper
(families Serranidae and Lutjanidae ), hard clams (Mercenaria mercenaria)

, rock shrimp (Sicyonia brevirostris) , white shrimp (Penaeus setiferus) , oysters (Crassostrea virginica) , blue crabs (Callinectes sapidus) , red drum (Sciaenops ocellatus) , and striped mullet (Mugil cephalus) are among the most commercially important and recreationally popular fi sh and shellfi sh in the IRL lagoon system. Commercial and recreational fi shing is a signifi cant source of local revenue. Preliminary 2005 commercial landings data collected through September 30, 2005, recorded more than 3.3 million pounds of

fi sh and invertebrates (including species used for bait) from Brevard, Indian River, and Volusia Counties over which the IRL Basin spans (FWC, 2006). More than half the landing total was recorded from Brevard County. Many fi sh species use the IRL lagoon system as a nursery. Adult fi sh such as tarpon, snapper, and grouper live off shore, but their larvae enter thelagoon system. Juvenile tarpon use mangrove marshes as a nursery (Sportfi sh Research Institute, 2006). Florida is the only location in the United States that tarpon use as a nursery (Sportfi sh Research Institute, 2006). Adult snook and red drum live in the IRL lagoon system but migrate to the inlets to spawn. Juvenile snook and red drum use mangrove marshes and seagrass beds, respectively, as nursery habitat. Mosquito impoundments also contain valuable habitat for juvenile fi sh. Much is unknown about the life history of fi sh species. Sportfish research efforts at the Florida Institute of Technology and the Florida Fish and Wildlife Research Institute
(FWRI) are directed toward fi lling those gaps. Over the past 50 years there have been accounts of decreasing fi sh and

shellfi sh populations in the IRL Basin, particularly snook and seatrout, documented by reduced landings, though further study and evaluation is needed. Changes in fishing regulations account for some of the landings reduction. Total commercial landings data from 1959 to 1962 for the 

# 43 Water Quality Assessment Report: Indian River Lagoon

# area from Ponce de Leon to Melbourne averaged about 6 million pounds (SJRWMD, 1996), almost twice the total for 2005. Upward trends in total landings in the 1970s through 1985 were attributed to increased harvest of hard clams (SJRWMD, 1996). Other threats specifi c to shellfi sh are the

closures of shellfish beds due to high levels of coliform bacteria or reclassifi

cation of beds as restricted or prohibited because of declines in water quality. There are fi shing accounts from the late 1800s and early twentieth century of large catches of snook, jewfi sh, and large sawfi sh. Sawfi sh and jewfi sh are no longer present in the IRL lagoon system. The spotted seatrout is a fish species that prefers estuarine environments and is usually associated with beds of SAV. Reported catch of spotted seatrout has declined since 1952. The 1988 spotted seatrout catch was only 40 percent of the catch recorded in the 1950s (Woodward-Clyde
Consultants et al., 1994). The common snook is a state-listed threatened species. The FWC began stocking hatchery-raised red drum at several locations in the IRLlagoon system in 1999 (FWC, 2005). About 17 percent of the hatcheryraised red drum released were later caught by anglers (FWC, 2005). Starting in 1986, the state and federal governments enacted regulations that

reduced the recreational harvest of red drum. Commercial harvest of red

drum was banned in 1988.

Biological Resource Issues Biological threats within the IRL Basin generally fall into fi ve categories: fragmentation or loss of habitat, water quality decline, excess exploitation of resources, introduction of exotic species, and stressed and

diseased fi sh and wildlife (SJRWMD, 1996). Continued urbanization

of the basin has resulted in confl icting human/wildlife uses or in the lossof wildlife habitats. Impoundment of coastal marshes and losses or degradation of seagrass beds reduced suitable fi sh habitat. Urban expansionand discharges from agriculture in the IRL Basin have increased stormwater runoff to the lagoon system. Associated with stormwater runoff are turbidity, nutrients, and other pollutants. The viability of SAV is reduced by increased turbidity in the water column due to the attenuation of light. The deposition of sediments causing turbidity can reduce the viability of benthic organisms. Exotic species are a constant threat to the biological integrity and vitality of the communities within the IRL Basin. Many of the exotics are of West Indian or tropical origin. Australian pine (Casuarina equisetifolia) was planted as a windbreak starting in the 1920s and formed extensive stands in upland hammock and forest areas south of Cape Canaveral. It is

a fi

re and temperature sensitive species and many trees were killed during freezes in the 1990s. In many places, Australian pine has been replaced by Brazilian pepper (Schinus terebinthefolius) , another invasive and exoticplant species that has overrun both upland and wetland habitats. Brazilian pepper is salt tolerant and tends to invade mangrove communities that have been disturbed. Its seeds are dispersed by birds. This species was not common as recently as the 1950s, but has since become quite abundant (Alexander and Cook, 1974). Cajeput or Melaleuca (Melaleuca 

# 44 Water Quality Assessment Report: Indian River Lagoon

# quinquenervia) is another Australian import that has invaded large areas

of south and central coastal Florida. Loss of fi re as an ecological control mechanism has also contributed to the expansion of invasive and exotic plant species.Since the completion of the IRL Comprehensive Conservation Management Plan in 1996, there have been several perplexing and disturbing episodes of wildlife-related disease and mortality in the IRL lagoon system. These events have raised concerns about the overall health of the estuary. The events noted over the past decade include

• The occurrence of a skin disease, Lobo mycosis , on many of the

lagoon’s resident dolphins.

• Large numbers of green turtles with fi bropapilloma lesions. The

disease was fi rst noted in 1982, but has become more prevalent in

recent years.

• An increase in the incidence of tumors in hard clams.

• A decrease in the number of horseshoe crabs. The horseshoe crab is

an important food source for loggerhead turtles and also shorebirds.

Numbers of horseshoe crabs have declined since the 1970s and 1980s
(Provancha, 1999).

• The appearance of saxitoxin in pufferfi sh in the northern segments of the lagoon. Catching pufferfi sh has been banned, and health advisories regarding consumption of these fi sh have been issued by the Florida Department of Health (DOH) (DOH, 2005). Saxitoxin is typically found in shellfi sh and, when affl icted shellfi sh are eaten, can cause paralytic shellfi sh poisoning. Investigations by the FWRI determined that a native alga produced the toxin.

• The appearance of the Australian spotted jellyfi sh (Phyllorhiza punctata) in the central lagoon area. These jellyfi sh were observed during summer months in 2001 and 2002, but not in 2003. This species eats large quantities of fish eggs, larvae, and microzooplankton. If it becomes a common inhabitant of the IRL lagoon system, it would have a negative impact on local fi sh populations. A volunteer monitoring program called Dockwatch has been organized to look for the Australian spotted jellyfi sh in the basin.

• The appearance of the exotic macroalga Caulerpa brachypus in the southern parts of the IRL lagoon system. It was fi rst observed in the spring of 2003 near Fort Pierce Inlet and St. Lucie Inlet, but has not been observed since that time. This alga originated in the Pacifi c Ocean with no known natural controls in Florida. Under certain conditions, it can cover submerged vegetation such as seagrasses and coral reefs, thus raising concerns over potential damage to seagrass beds if it ever became established in the IRL lagoon system. 

# 45 Water Quality Assessment Report: Indian River Lagoon

# In an effort to address the above problems, the Indian River Lagoon Biotoxin and Aquatic Animal Health Task Force was created by the Indian River Lagoon National Estuary Program (IRLNEP) and the FWRI (SJRWMD, 2006c). In early 2006, the Task Force recommended threeresearch projects for funding, which aimed at providing a better understanding of the relationship between observed aquatic animal health issues and possible effects of biotoxins. Projects include literature review to document historical events, epidemiological linkages between disease and exposure to saxitoxin, and monitoring phytoplankton populations to determine their distribution (SJRWMD, 2006b).



# Ground Water Resources

Aquifers Hydrologically, the eastern boundary of the IRL Basin is the Atlantic

Oc ean and the western boundary is the drainage divide formed by the
Talbot Terrace (25 to 42 feet above mean sea level [MSL]) (Bermes, Leve, and Tarver, 1963). The terrace divides rainfall runoff into an easterly drainage toward coastal lagoons and the Atlantic Ocean and a westerly drainage toward the St. Johns River. The basin is covered by undifferentiated sediments of Pleistocene and Holocene ages that consist of sand and clay, dune sand, and coquina and shell debris near the coast. Together with some isolated peat deposits in the lakes and marshes, this layer of undifferentiated sediments comprises

the surfi cial aquifer in the area. The surfi cial aquifer is unconfi ned andbetween 50 and 100 feet in thickness. In general, it is thicker in the southern part of the IRL Basin (Scott, Lloyd, and Maddox, 1991).

The surfi cial aquifer is underlain by interbedded lenses of marine, fi ne to medium sand, shell, and silty clay of Pliocene and Upper Miocene ages that lie on top of a confi ning layer, the Hawthorn Formation of Miocene age. The Hawthorn Formation consists of plastic, phosphatic, sandy clay, and marl interbedded with lenses of phosphorite pebbles, phosphatic sand,and phosphatic sandy limestone (Bermes et al., 1963). The Hawthorn Formation is from 50 to 200 feet in thickness in the basin (Scott et al., 1991). The intermediate aquifer is confi ned and consists of more permeable lenses
of sand, shell, and limestone that occur within the confi ning layer. This aquifer is a locally important water source. The Floridan aquifer system, which is confined, lies beneath the Hawthorn Formation. In the IRL Basin, the Floridan aquifer consists of a series of limestone formations of Eocene age; in descending order, these include the Crystal River Formation, Williston Formation, Inglis Formation, Avon Park Limestone, and Lake City Limestone (Bermes et al., 1963). The top of the Floridan aquifer is located between 100 and 400 feet below MSL, with a thickness of approximately 2,000 feet. The Floridan aquifer isunder artesian pressure (Scott et al., 1991), and wells completed in the Floridan aquifer can fl ow if they are not capped. There are also fl owing springs offshore in the Atlantic Ocean that discharge from the Floridan aquifer. 

# 46 Water Quality Assessment Report: Indian River Lagoon

# Ground Water–Surface Water Interactions Precipitation in the IRL Basin runs off to the Atlantic Ocean, to the

I RL lagoon system (Intracoastal Waterway) between the barrier islands and the mainland, or to streams, canals, wetlands, lakes, and ponds. It also

infi ltrates to recharge the surficial aquifer and, in turn, part of the intermediate aquifer. The IRL Basin is a discharge area for the artesian Floridan aquifer. The potentiometric surface of the Floridan aquifer ranges from 0 to 35 feet above MSL along the coastline. The amounts of upward fl ux through seepage, springs, sinks, or unplugged wells to the surficial and intermediate aquifers and to surface waters (including points offshore beneath the Atlantic Ocean) depend on the thickness and the extent of breaching of the overlying confi ning layer. The surface water in the basin could be a mixture of direct precipitation, surface runoff, seepage from the surfi cial aquifer, and discharge from the Floridan aquifer. In the near-coastal areas and in the vicinity of canals that do not have salinity control structures,

saltwater intrusion into the surfi cial aquifer occurs.

Ground Water Usage

Both the surfi cial and Floridan aquifers are signifi cant sources of water for public supply, agriculture, and industrial uses, although surface water is also relied on. The intermediate aquifer is used to a lesser extent but can be a locally important water source. The Floridan aquifer, because of its depth and location in the IRL Basin, contains brackish water. In this area, water drawn from the Floridan aquifer may be blended with water

drawn from the surfi cial aquifer or surface waterbodies as drinking water supply. According to the Department’s Public Water System database, there are 269 public supply wells in the basin that provide water for potable supply, 141 of which provide water to communities. The city of Vero Beach (34 wells), the city of Palm Bay (27 wells), and the city of Titusville (17 wells) have the largest number of public supply wells in the basin. The Vero Beach wells all draw water from the Floridan aquifer; Palm Bay and

Titusville wells draw from the surfi cial aquifer. Figure 2.5 shows public supply wells in the basin.

Ground Water Quality Issues A well-known and signifi cant ground water quality issue in the IRL Basin is the naturally occurring high content of sodium and chloride in the Floridan aquifer and to a lesser extent in the intermediate aquifer. This is due to the natural setting of the coastal basin and the underlying aquifers.Ground water is artesian, with a high yield in the Floridan aquifer. However, the upper Floridan aquifer, especially its deeper part and at locations closer to the coast, may contain up to 3,000 milligrams per liter or more of chloride. This situation is further aggravated by the increasing pumpage ofwater supply wells associated with the basin’s growing population and agricultural and industrial activities. The vertical upwelling of high chloride– high sodium water induced by pumping wells is a signifi cant problem for public water supplies in the basin. In some cases, water withdrawn from the Floridan aquifer must undergo membrane treatment and be blended 

# 47 Water Quality Assessment Report: Indian River Lagoon

# with water from the surfi cial aquifer before it can be used as public water supply or agricultural water supply. Another issue pertains to the use of the Floridan aquifer as a source of irrigation water for citrus groves in the basin. In addition to the other problems caused by overproduction, the high-salinity water is infiltrating into the surfi cial aquifer and being discharged to canals. This results in potential localized impacts to the surfi cial aquifer and fresh surface

waterbodies. Ground water quality in the IRL Basin is affected in some areas bycontaminant sources; these are being addressed by several programs managed by the Department and a number of sites or facilities are included in Department databases. Figure 2.5 shows the known sources of contamination in the IRL Basin. These include the following:

1. Federal Superfund Sites: There are two Superfund sites on the National Priority List in the
basin, as follows:

Harris Corporation Superfund Site, Palm Bay: This 300-acre electronics manufacturing facility site is associated with a plume of volatile organics that affected the adjacent wellfi eld owned by Palm Bay Utilities. Palm Bay Utilities provides drinking water to approximately 33,000 Palm Bay residents. The site is currently under remediation, which involves ground water extraction and

treatment.

Piper Aviation Superfund Site, Vero Beach: This small site adjacent to the Vero Beach Municipal Airport is associated with soiland ground water contamination by volatile organics and the contamination of a city of Vero Beach municipal supply well. Ground water extraction and treatment are currently ongoing.

2. State-funded Waste Cleanup Program Sites: There are three State-funded Waste Cleanup Program sites in the basin: the Cocoa Beach Gasoline Contamination cleanup site, the Weekley Lumber wood preserving waste site, and the Skippers electroplater’s cleanup site.

3. Petroleum Contamination Monitoring Sites:There are more than 900 known petroleum contamination monitoring sites in the basin. These sites are undergoing ground water monitoring, and some of them are undergoing cleanup. Public orprivate drinking water supplies affected by petroleum contamination will be protected in one of several ways: by decommissioning the affected well and providing water from an alternative source, by providing treatment at the water plant, or, for affected residential wells, by installing activated carbon filters to remove the contamination and meet drinking water standards.

4. State Dry Cleaning Program Sites: About 35 dry cleaning program sites have been identifi ed in the basin. All of them are located in cities such as New Smyrna Beach, 

# 48 Water Quality Assessment Report: Indian River Lagoon

# Figure 2.5: Public Supply Wells and Potential Sources of Contamination in the Indian River Lagoon Basin 

# 49 Water Quality Assessment Report: Indian River Lagoon

# Titusville, Cocoa Beach, Merritt Island, Melbourne, and Vero Beach. Affected water supplies will be addressed as described for petroleum facilities.

5. Delineated Ground Water Contamination Area (not depicted in Figure 2.5): One delineated ground water contamination area is present in the basin and is located in Palm Bay in Brevard County. Ground water at the site contains metals and volatile organic compounds in concentrations that exceed ground water standards.

Priority Water Resource Caution Areas Parts of the IRL Basin are in a Priority Water Resource Caution Area
( PWRCA) designated by the SJRWMD. The parts of the basin included in the PWRCA designation are depicted in Figure 2.6 and generally include south Volusia County, north Brevard County, and Brevard County

beach communities.
Under Section 373.036, F.S., and Subsection 62-40.520(1), F.A.C., each water management district in the state must identify PWRCAs 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 PWRCAs:

• 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.



# Watershed Management Activities and Processes

Over the years, management plans and activities in the IRL 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. Table 2.3 provides a summary of water quality issues

that confront the basin. Much of the progress in the IRL Basin in developing water qualityrestoration plans and implementing watershed and water quality improvements is attributable to coordinated local, state, and regional efforts. Many 

# 50 Water Quality Assessment Report: Indian River Lagoon

# Figure 2.6: Priority Water Resource Caution Areas within the Indian River Lagoon Basin 

# 51 Water Quality Assessment Report: Indian River Lagoon

# plans share common goals, and their implementation is based on variousgroups playing 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.

Pollutant Load Reduction Goals
Pollutant Load Reduction Goals (PLRGs) are defi ned as “estimated numeric reductions in pollutant loadings needed to preserve or restore ... receiving bodies of water ...” (Chapter 62-40.210[20] F.A.C.). The state of Florida has directed its water management districts to establish PLRGs as part of a Surface Water Improvement and Management (SWIM) plan or other plans, or as a basin rule (SJRWMD, 2006a). A preliminary PLRGhas been developed by the SJRWMD for the IRL lagoon system that targets the restoration and enhancement of seagrass beds in the lagoon. Seagrass is a critical habitat for fi sh and other marine and estuarine organisms. The most important factor infl uencing seagrass growth, abundance, and depth distribution is the amount of light that reaches the grass bed
(as referenced in Steward and Green, 2006; Morris, Virnstein, and Miller, 2002). Water clarity is the primary indicator of light availability and controls the depth to which light will penetrate the water column. Water quality factors that infl uence water clarity are turbidity caused by total suspended solids (TSS) loading, sediment resuspension, phytoplankton Table 2.3: Summary of Water Quality and Habitat Issues in the Indian River Lagoon Basin

Habitat Loss and Habitat Change

• Loss of seagrass beds

• Loss of fishery resources

• Isolation of salt marsh and mangrove habitat by mosquito
impoundments

• Stresses to environmentally sensitive species

Water and Sediment Quality

• Increased fresh water discharges and changes in timing because of
changes to drainage patterns

• Changes in circulation and flushing because of channel dredging, inlet
stabilization, and causeway construction

• Fluctuations in salinity at tributary stream mouths from release of too

much fresh water

• Nutrient loading from stormwater runoff

• Increased levels of bacteria and pathogens

• Increased levels of suspended particles

• Increased levels of toxic substances and contaminated sediments

• Formation of muck bottom in numerous areas, particularly at the mouth

of tributaries

• Impacts of increased boating by resuspension of bottom sediments and

shoreline erosion 

# 52 Water Quality Assessment Report: Indian River Lagoon

# densities, and water color. Nutrient over-enrichment in the lagoon can trigger excessive growth of phytoplankton, which can successfully compete against seagrass and other macrophytes for available light. The pollutants of concern to seagrasses, and for which the PLRG was developed, weretherefore nutrients (total nitrogen and total phosphorus, which fuel phytoplankton growth) and TSS. Seagrass restoration targets were established for the IRL and Banana River Lagoon (Steward and Green, 2006). Mosquito Lagoon was not included in the PLRG developed for the IRL lagoon system because change of seagrass coverage in the lagoon was not suffi cient to identify the causative pollutant. A description of the PLRG development process for the IRL lagoon system is provided in the Seagrass Assessment section of Chapter 3.

Relationship between Pollutant Load Reduction Goals and Total Maximum Daily Loads 

# Several segments of the IRL and Banana River were listed on the 1998 303(d) list and required development of TMDLs. The U.S. Environmental Protection Agency (EPA) proposed TMDLs for 18 segments for nutrients, chlorophyll a , and dissolved oxygen on June 30, 2003 (EPA, 2007a). The EPA used the established provisional PLRGs (estimated 1943 watershed loads corresponding to the seagrass benchmark year of 1943) as the basis for calculation of TMDL loading targets. EPA fi nalized its TMDLs in April 2007, based on the PLRG updated by the SJRWMD in March 2006
(Steward and Green, 2006).

Major Programs, Plans, and Projects that Protect and Improve Water Quality and Biological Resources 

# There are several layers of resource management and protection afforded to the IRL Basin across federal, state, and local jurisdictions. The IRL is a designated SWIM Priority Water and a National Estuary.A number of major restoration initiatives and water quality improvement projects will have significant positive effects on the basin’s water quality if continued. More information about individual current projects under way is listed in Appendix C

.

Indian River Lagoon Act 

# Passed in 1990 by the Florida legislature, the Indian River Lagoon Act (IRL Act), also known as Chapter 90-262, Laws of Florida, required that domestic wastewater treatment plants stop discharging into the IRLlagoon system by April 1, 1996. Before 1995, domestic wastewater treatment plants contributed 15–20 percent of the nutrient loading of the lagoon system. For some segments that loading was substantially higher, as much as 70 percent of the nutrient loading. Other than occasional wet weather discharges and other discharges allowed under subsequent legislation, domestic wastewater in the basin has been substantially reduced. Cape Canaveral, Edgewater, and New Smyrna Beach, in addition to providing wastewater for reuse, continue to discharge a portion of their wastewater to the lagoon system, though each community is working to reduce or cease discharge (Steward, 2006). Currently, domestic wastewater discharges 

# 53 Water Quality Assessment Report: Indian River Lagoon

# contribute less than 2 percent of nutrient loading to the lagoon system
(Steward et al., 2003). The IRL Act also required that package wastewater treatment plants be evaluated for their potential threat to the water quality of the IRLlagoon system. Many package plants have been connected to larger wastewater treatment plants and are now out of service. Some, however, are outside the service area of larger domestic wastewater plants and remain
in operation.

Surface Water Improvement and Management Priority Waters 

# In 1987, the Florida legislature created the SWIM Program to restore waterbodies. The IRL was designated a SWIM waterbody in 1987 as part of the legislative act creating the SWIM Program. The fi rst SWIM plan was prepared and approved in 1989 with subsequent updates in 1994

and 2002. Three major SWIM goals were identifi ed for the IRL and its watershed. They include

• Attain and maintain water and sediment quality that will support a

healthy macrophyte-based estuarine lagoon ecosystem;

• Attain and maintain a functioning macrophyte-based ecosystem that

supports endangered and threatened species, fi sh, and wildlife; and

• Heighten public awareness and coordinate interagency management

of the IRL watershed.

The initial SWIM legislation identifi ed 5 other priority waterbodies in addition to the IRL: Lake Apopka, Tampa Bay, Biscayne Bay, Lower St. Johns River, and Lake Okeechobee. Today, the program has expanded to include SWIM waterbody designation for 31 waterbodies statewide.The SWIM Program addresses a waterbody’s needs as a system of connected resources, rather than isolated wetlands or waterbodies. The state’s5 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.

Indian River Lagoon National Estuary Program 

# The IRLNEP was established in 1990. The SJRWMD was selected as the program sponsor responsible for providing staff support and localadministration of federal funds. A Comprehensive Conservation and Management Plan (CCMP) for the IRL was completed in 1996 and updated in 2007 (SJRWMD, 1996; SJRWMD, 2008). The IRLNEP was built on the goals and objectives of the IRL SWIM Program outlined above with an additional fourth goal of long-term commitment to implementing

the CCMP. One of the primary responsibilities of the IRLNEP is to foster active participation of other governmental entities and community members. Since 1994, the IRLNEP has assumed sole responsibility for public 

# 54 Water Quality Assessment Report: Indian River Lagoon

# involvement and education activities. The IRLNEP manages a localgovernment cost share program targeted at small-scale projects, typically stormwater retrofi ts and improvements. The program is able to raise revenue for habitat restoration, water quality improvement, and education programs through the sale of a specialty license plate.

National Park and National Wildlife Refuges 

# About half of the wetlands and a large portion of the open water and uplands in the IRL Basin are under the jurisdiction of the National Park Service and the U.S. Fish and Wildlife Service. Federally managed lands

are listed in Table 2.4 . The National Park Service completed revision of the Canaveral National Seashore Water Resource Management Planin 2001 (Steward et al., 2003). The plan directs water-related management and public use activities for a 5- to 10-year period. The U.S. Fish and Wildlife Service has resource management responsibility over close to150,000 acres of national wildlife refuges. Refuge comprehensive conservation plans are developed for each refuge to outline water and land management within the refuge. Plans are revised every 15 years.

Indian River Lagoon North Feasibility Study

# The U.S. Army Corps of Engineers (USACOE) has initiated feasibility studies with the intent of evaluating and designing restoration projects for the northern and southern parts of the IRL. The USACOE’s activity is part of the overall Comprehensive Everglades Restoration Plan in response to the impacts of environmentally undesirable effects of fl ood control and drainage improvement done between the late 1940s and early 1980s. The major flood control project, the C&SF Project, has resulted in the diversion of large quantities of water from the Upper St. Johns Basin to the IRL lagoon system. The IRL North Feasibility Study began in 2002 and was reinitiated in 2007. It includes parts of the basin located in Volusia, Brevard, and Indian River Counties. The SJRWMD is the local sponsor and cooperator withthe USACOE on the study and has a role in the review and recommendation of improvement projects. The feasibility study is anticipated to be completed in 2008 and submitted to the U.S. Congress for authorization and funding approval in 2009 as part of the reauthorization of the Water Resources Development Act.

# The feasibility study has incorporated the goals and objectives of the IRL CCMP and the IRL SWIM Plan. Potential projects include muckremoval from canals or the Intracoastal Waterway and drainage infrastructure improvements.

Special Districts and Florida Inland Navigation District 

# There are three different types of special taxing districts in the basin: water control district, navigation district, and mosquito control district. Also known as Chapter 298 drainage districts, water control districts are special taxing entities that were created in 1916 by the Florida legislature to promote agriculture. There are fi ve active water control districts in the IRL
Basin: Melbourne–Tillman, Fellsmere, Vero Lakes, Sebastian River, and

Indian River Farms. The water control districts constructed and continueto maintain networks of drainage canals built largely to drain land for agricultural production. Water control districts are partners with SJRWMD, SFWMD, and USACOE in developing techniques to reduce the quantity and improve the quality of stormwater discharges. Florida Inland Navigation District (FIND) was created in 1927 by an act of the Florida legislature. The creation of FIND was spurred by passage of the 1927 River and Harbor Act by the U.S. Congress, which authorizedthe establishment and maintenance of an inland waterway starting in Jacksonville (FIND, 2005). FIND is Florida’s sponsor for maintenance dredging of the Intracoastal Waterway along Florida’s coast. The responsibilities of FIND include developing dredging plans, acquiring and preparing sitesfor dredge spoil, and generally engaging in activities that enhance navigation. FIND is partnering with SJRWMD, SFWMD, and USACOE to provide cost sharing and technical assistance with muck removal projects. Mosquito control districts were created by the Florida legislature with the specifi c responsibility of mosquito abatement. Responsibility for mosquito abatement in the IRL Basin rests with Volusia County Mosquito Control, Indian River Mosquito Control District, and Brevard County Mosquito Control. For more information, see http:// www.fl orida mosquito.org/index_mosqinfo.html. The Indian River Mosquito Control District was the fi rst district created in Florida with a founding year of 1926. A large part of the basin would be uninhabitable without mosquito control. Prior to the 1950s, control methods were based on ditching and draining of wetlands and spraying. Starting in the 1950s, the management technique of impounding coastal marshes for mosquito control was introduced. This technique takesadvantage of a unique biological feature of the salt marsh mosquito (Saltmarsh Mosquito Control, 2007). This mosquito species will not lay eggs directly on water. From the 1950s to the 1970s, close to 75 percent of the coastal wetlands in the IRL Basin were impounded for mosquito control
(Steward et al., 2003).

Indian River Lagoon Blueway Program 

# The Indian River Lagoon Blueway Program is a purchase program for environmentally sensitive or critical lands. It is loosely based on the greenways concept of connecting critical habitats or sensitive lands through 

# 56 Water Quality Assessment Report: Indian River Lagoon

# upland corridors; however, in the case of a blueway, such lands are accessible and connected by water. The Blueway Program is a partnership between the SJRWMD, SFWMD, county governments, the Department, and The Nature Conservancy. The program has identifi ed over 8,000 acres in about 600 parcels for purchase. Much of the lands identified for acquisition are wetlands and their associated uplands.

Urban Stormwater Management 

# Stormwater generated in urban areas is managed through the National Pollutant Discharge Elimination System municipal separate storm sewer system (MS4) permitting program. The counties, military installations, and a number of local governments are included in Phase 2 of the MS4 program. Governments with Phase 2 MS4 permits are listed in Table 2.5

. Phase 2 MS4 permits address six distinct program areas. Two important MS4 program areas are the detection and remediation of illicit connections (nonstormwater) to the storm sewer system and pollution prevention public

education.

# 57 Water Quality Assessment Report: Indian River Lagoon

# Numerous local governments have enacted stormwater utilities to help pay for stormwater management and remediation activities. These municipalities are listed in Table 2.6 along with the rate of their stormwater utility fee. The equivalent residential unit is the standardized area ofimpervious surface assigned to one residential unit. Commercial development rates are based on the amount of impervious area compared to the

standard residential area and rate. Brevard County instituted its stormwater utility in 1990. The county has funded approximately $20 million in stormwater improvement projectssince its inception (Powers, 2006). Brevard County has completed stormwater management plans for the Eau Gallie River and Crane Creek Basins.The Crane Creek plan includes Melbourne, West Melbourne, and unincorporated Brevard County. Malabar and West Melbourne joined the Brevard County stormwater utility in 2000 and 1999, respectively (Brevard County Stormwater Utility Department, 2005a). Brevard County acts as the administrator of the utility. Brevard County’s Stormwater Utility Department developed andimplemented a Stormwater Utility Assessment Credit program for properties that are serviced by approved and maintained stormwater treatment systems (Brevard County Stormwater Utility Department, 2005b). Thecredit program provides for reductions in stormwater assessments for different degrees of landowner implemented and maintained stormwater treatment. A compliance inspection of the private treatment system is part of the overall credit program. Table 2.6: Local Governments with Stormwater Utilities in the Indian River Lagoon Basin

# Cocoa Beach Green Business 

# The city of Cocoa Beach initiated a pilot Green Businesses Program in 2004 in which local businesses agreed to follow best management practices (BMPs) designed to prevent pollution. In exchange, the businesses are promoted to the public as green businesses. Restaurants, paint and masonry contractors, and lawn services are the target industries included in the pilot project.

Florida Department of Environmental Protection Clean Marina, Clean Boatyard, and Clean Boater Programs 

# The Clean Vessel Act of 1994 prohibited boaters from discharging raw sewage into either freshwaters or coastal saltwaters within state jurisdiction (Section 327.53[4][a], F.S.) (Department, 2006a). For Florida’s Atlantic Coast, jurisdiction extends offshore to three nautical miles. The CleanVessel Act Program was undertaken to provide strategies for construction and repair of boat sewage pump outs at marinas. The Clean Marina, Clean Boatyard, and Clean Boater Programs were a natural extension of the Clean Vessel Act Program needed to address a broader agenda of issues and concerns faced by marina and boatyard owners beyond the pump out of

wastewater. The Clean Marina and Clean Boatyard Programs focus on owners and operators of facilities that support the boating community either by slip rental or repair and construction services. The Clean Boating Partnership oversees the development and implementation of these programs. The partnership is an alliance comprising the Department’s Division of Law Enforcement, Marine Industry of Florida, Florida Sea Grant Program, U.S. Coast Guard, International Marina Institute, and representatives of municipal and privately owned marinas. Facilities can become designated as a Clean Marina or Clean Boatyard by following a detailed checklist of clean boating BMPs developed for the industry and current regulations. The partnership provides workshops for the marine industry. To receive designation as a Clean Marina or Clean Boatyard, a facility is subjected to a walk-through inspection and verifi cation of its checklist by members of the partnership and staff from the Department’s Central District Offi ce. The marina or boatyard receives a plaque and fl ag to fl y over the facility

and is also identified as a Clean Marina or Clean Boatyard on the Department’s Web site and in industry service directories (Department, 2006b). Currently, there are 11 certifi ed Clean Marinas/Clean Boatyards in the IRL Basin (Department, 2005f). There are at least 26 marinas in the basin that provide sewage pump-out services (Department, 2005f). The Clean Boater Program focuses on the recreational boater through educational materials. Boaters are asked to take a “Clean Boater Pledge” and receive the Clean Boating Habits booklet (containing recommendedBMPs or individual actions for boating safety, storm preparedness, pollution reduction, and aquatic plant and animal life protection), Clean Boater Sticker for their boat, and other shipboard items that serve as prompts for clean boater behavior (Department, 2006b). 

# 59 Water Quality Assessment Report: Indian River Lagoon

# Agricultural Best Management Practices

# The Florida Watershed Restoration Act authorizes the Florida Department of Agriculture and Consumer Services (DACS) to develop interim measures and agricultural 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 (IFAS), and other major interests to improve product marketability and operational efficiency by implementing agricultural BMPs, while at the same time promoting water quality and water conservation objectives. For example, Brevard County provides a 100 percent stormwater assessment credit to agricultural entities who implement a National Resource Conservation Service plan that includes BMPs and other activities to address runoff from agricultural properties (Powers, 2006). 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.

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. BMP manuals pertinent to the IRL Basin include the following:

• Guide for Producing Container-Grown Plants: This manual,

published in 1995 by the Southern Nurserymen’s Association,includes irrigation and fertilization BMPs for the container cultivation of nursery plants. It was produced through a cooperative effort between the University of Florida, Auburn University, Tennessee Tech University, and Virginia Tech. Because the manual is not Florida-specifi c, an effort is currently under way to use the document in developing a Florida-specifi c manual. 

# 60 Water Quality Assessment Report: Indian River Lagoon

# • Best Management Practices for Agrichemical Handling and Farm Equipment Maintenance: Recently revised and reprinted, this manual gives producers guidance on hazardous materials, proper pesticide handling, and the proper disposal of waste products. It was cooperatively produced in 1998 by DACS, the Department, and several industry associations.

• Water Quality Best Management Practices for Cow/Calf Operations: Many cattle operators statewide have been trained in using this manual and are applying BMPs. The Florida Cattlemen’s Association and several state, federal, and local agencies developed the manual, which was published in 1999. Copies were printed and distributed in 2000 using EPA Section 319 grant funds.

• Water Quality/Quantity Best Management Practices for Indian

River Area Citrus Groves: The regional BMPs in this manual apply to all or parts of the east coast counties in which the IRL Basin
lies (Volusia, Brevard, and Indian River Counties). The Indian River Citrus League led a cooperative effort involving 15 agencies and industry associations in developing these BMPs. Beginning in 2000, the BMP manual and guidance booklets were published using EPASection 319 and industry funds. IFAS has evaluated BMP compliance for DACS on 3,302 acres in Brevard County and 48,712 acres in Indian River County (Boman, 2005). These acreages include both the IRL and the Upper St. Johns Basins. Since the evaluations were performed, large areas of citrus have been lost as a result of hurricane damage, urbanization, and canker.

• Aquaculture Best Management Practices: As directed by the

1998 Florida legislature, DACS worked cooperatively with industry, state agencies, and the environmental community to develop a comprehensive BMP manual for aquaculture. Florida law requiresthat the Department adopt the manual by rule and provides regulatory exemptions under Chapters 373 and 403, F.S., for growers who implement BMPs and are certified by DACS’ Division of Aquaculture. The manual, which was printed and distributed in 2000, has been adopted by rule.

• Florida Green Industries Best Management Practices for Protection of Water Resources in Florida: This manual provides BMPs for professional turfgrass and landscape managers. Published in 2002, it was developed through a cooperative effort by Florida Green Industries (an industry association); the Department; DACS; the Florida Department of Community Affairs; and the St. Johns, South Florida, and Southwest Florida Water Management Districts.

• Rule-Based Initiatives: Under Chapter 576, F.S., in 2002 DACS

adopted citrus BMPs by rule for the Lake Wales Ridge region, and in 1996 adopted BMPs by rule for leatherleaf fern production areas in and around Volusia County.

# Working Groups and Nongovernmental Organizations 

# Intergovernmental working groups and volunteer citizen groups play an important role in the restoration and enhancement of the IRL Basin. The partnerships created between government, nongovernmental organizations, and private citizens have provided numerous opportunities for restoration and protection of the IRL Basin.

Friends of Turkey Creek

# The Friends of Turkey Creek is a volunteer group comprising homeowners along Turkey Creek. The group is directed by a six-member advisory board. The group’s interest is to maintain the navigability of the creek while also protecting its ecological value as fi sh and wildlife habitat. Sedimentation in the creek is a continual problem. The group plays an active role in seeking funding for the C-1 rediversion project.

Marine Resources Council 

# The Marine Resources Council (MRC) was founded as a volunteer organization over 15 years ago. This organization focuses on problems that impact the IRL lagoon system. Important issues of concern to the MRC are loss of seagrasses; negative impact of stormwater runoff on the lagoon; coordination of local, state, and federal programs for the lagoon; and the need for public input to better inform elected offi cials. The MRC is directed by a board of directors supported by staff. The MRC is currently involved with the IRL Greenway Committee, Indian River Lagoonwatch volunteer water quality monitoring program, and hosts “State of the Indian River Lagoon” public education workshops on a variety of timely topics. Past public education workshops have includedtopics such as septic tank problems, manatee plans, impacts of port development, and the Everglades restudy (Marine Resources Council of East
Florida, 2005).

Brevard and Indian River Counties Stormwater Working Group 

# Organized and managed by the SJRWMD, this group comprises local government and water control district stormwater managers and staff. The working group provides a forum for exchange of technical information about stormwater management issues and techniques and coordination of funding proposals for stormwater projects.

Friends of the St. Sebastian River 

# The Friends of the St. Sebastian River is a nongovernmental nonprofi t organization governed by an independent elected board (http://home. comcast.net/~fssr/). Its goals are to promote and protect environmentaland recreational opportunities, improve water quality, promote safe boating practices, protect wildlife by supporting manatee protection, promotepublic education and awareness, and encourage conservation of the Sebastian River. The group accomplishes its goals through cooperation and participation with governmental agencies and other organizations that protect the Sebastian River. 

# 62 Water Quality Assessment Report: Indian River Lagoon

# Environmental Learning Center 

# The Environmental Learning Center is a private nonprofit organization located on Wabasso Island in Indian River County (http://www .elcweb.org/). The primary goal of the Center is to provide residents with an understanding of the natural world and to motivate them to protect it. About 80 percent of the Center’s activities are funded by membership fees, private donations, and fund-raising events.

Brevard Nature Alliance, Inc.

# The Brevard Nature Alliance, Inc., sponsors and promotes the development of nature-based education and activities throughout Brevard County (http://www.natureandspace.com). The Alliance is a nonprofit organization that acts as a central agency for analyzing area natural resources and physical needs to help develop long-range plans for Brevard County. The Alliance can provide expertise and guidance for local governments and nongovernmental organizations in the expenditure of funds for community environmental development.

Natural Resource Protection and Water Quality Improvement Projects Overview

C-1 Rediversion Project 

# The purpose of this project is to divert the discharge from the

Melbourne–Tillman Water Control District’s C-1 Canal westward toward the Upper St. Johns River Basin. The canal was built to drain marshes in the Upper St. Johns River Basin, creating suitable land for agriculture. Discharges through the canal into Turkey Creek could reach 500 million gallons per day after storms (Steward et al., 2003). The increased volumesof freshwater discharged through Turkey Creek to the IRL caused a lowering of salinity in the lagoon, added large loads of nutrients and sediments to
it, contributed to the decline of the hard clam fi shery, caused fi sh kills, and reduced the area of seagrasses at the mouth of Turkey Creek. The larger

volumes of water fl ushed through Turkey Creek have caused the erosion of the creek’s banks, sedimentation, and damage to wildlife habitat along the

creek bank. The C-1 rediversion project is a Section 206 project jointly funded by the Melbourne–Tillman Water Control District, SJRWMD, and USACOE. Project plans require the construction of a spillway in the C-1

Canal to divert stormwater west to the C-1 Retention and C-1 Detention

Areas. Water will be returned from the C-1 Retention and Detention Areas to the Sawgrass Lake Water Management Area for additional water quality treatment before discharge to the St. Johns River. Construction of the C-1 Retention and Detention Areas and the Sawgrass Lake Water Management Area will result in the creation of 4,000 acres of wetland in the Upper St. Johns River Basin. The project is expected to help TurkeyCreek and the IRL meet PLRGs for nutrient and suspended solids reductions (Steward et al., 2003). Other expected benefi ts of the project are the recovery of 280 acres of seagrass beds, recovery of as much as 3,000 acres

of shellfi sh beds, and the reduction of the erosion of Turkey Creek’s bank. The tentative time frame for project completion is 2008. Because of federal 

# 63 Water Quality Assessment Report: Indian River Lagoon

# budgetary concerns, the SJRWMD has made a commitment to move forward with project design and construction (Steward, 2006).

Sebastian River Watershed 

# The Sebastian River is the largest tributary to the IRL lagoon system. It also provides some of the largest loadings of suspended solids and nutrients. Several projects, in addition to dredging of muck from the Sebastian River, are planned in this river basin for improved fl ood control, salinity maintenance, and reductions in loads of nutrients and suspended solids. The city of Sebastian has prepared a surface water master plan that addresses pollutant reduction and fl ood control. Parts of the plan

include the construction of a dam on the Elkam Canal and a stormwater treatment pond that treats Stonecrop drainage. SJRWMD is completing construction of a stormwater treatment park in the southern part of the city of Sebastian (Steward, 2006). Within the North Prong Sebastian River drainage, 496 acres have been set aside for a stormwater treatment area near Sottile Canal to treat runoff from projected build-out of Barefoot Bay and for dredge spoil disposal. Plans are in progress between SJRWMD,
USACOE, Sebastian River Water Control District, and Fellsmere Water Control District to address stormwater management and erosion control
(Steward et al., 2003).

Indian River Farms Water Control District 

# Discharges from the Indian River Farms Water Control District, delivered through North, Main, and South Canals, impacts about 12 milesof the southern part of the IRL. Water quality and the condition of seagrasses in the area are poor compared with other segments of the lagoon. Starting in 2001, responsible agencies including Indian River County, SJRWMD, Indian River Farms Water Control District, Vero Beach, and the Indian River County IFAS Extension Offi ce organized to developa water management plan. The development of the plan is challenging because the plan will need to balance restoration needs of the IRL and drainage needs. Other state and federal agencies will join the effort as plans become solidifi ed. The Florida legislature appropriated about $5 million to support the effort (Steward et al., 2003; Steward, 2006).

On-site Sewage Treatment and Disposal Systems 

# On-site sewage treatment and disposal systems (OSTDSs), usually septic tanks and drain fi elds, are common in parts of the IRL Basin where population densities are low or outside utility service areas. Some of the older systems constructed before 1983 may have drain fi elds located 6 inches or less from the high water table and may have limited capability to treat wastewater (SJRWMD, 1996). The IRL SWIM Plan was required by the IRL Act, in addition to evaluating the loading from domestic wastewater treatment plants, to evaluate OSTDSs and identify problemareas that could potentially impact the IRL lagoon system. Actual evaluations were performed by county public health units under contract to the SJRWMD in the early 1990s. Problem areas were ranked for the severity of threat considering soil permeability, depth to water table, failure, and 

# 64 Water Quality Assessment Report: Indian River Lagoon

# density of septic tanks. Volusia County identifi ed 32 square miles as problem areas and another 26.7 square miles as potential problem areas. Brevard County identifi ed 22 square miles as problem areas and 9.6 square miles as potential problem areas. Indian River County prioritized areas ashigh or medium priority and found that 15.4 square miles were high priority while 16 square miles were medium priority (SJRWMD, 1996). In response to these fi ndings by county public health units, counties took specifi c steps to at least attempt to address the most severe problems. In response to fi ndings for Mosquito Lagoon, Volusia County and New Smyrna Beach provided sewer service to barrier island communities from

Ponce de Leon Inlet south to Canaveral National Seashore. There are still

areas of the mainland that should be considered for central sewer. Brevard County’s evaluation of the Banana River watershed identifi ed most septic tank systems are on the southern end of Merritt Island. Most problems were located in the Newfound Harbor area and many of those homes were provided central sewer service. Remaining septic tanks on Merritt Island are located on Horti Point and are considered a low pollution threat to

the Banana River. Problem areas identifi ed by Brevard and Indian RiverCounties were Port St. John, Palm Bay, southern Brevard County, Sebastian, and southeastern Indian River County. Palm Bay and Indian River County are continuing to eliminate the use of OSTDSs. Major obstacles for the removal of OSTDSs are the cost to the homeowner of connecting to
central sewer (Steward et al., 2003).

Wetland Restoration 

# Wetlands in the IRL Basin have been impacted in many ways. About 75 percent of the coastal salt marshes in the basin were impounded and isolated from open waters for the control of salt marsh mosquitoes by mosquito control districts (Indian River Mosquito Control District, 2007). Research performed in the 1970s and 1980s showed that there was an ecological benefi t to reconnecting salt marshes to the estuary. Research by Brockmeyer, Rey, Virnstein, Gilmore, and Earnest (1997) was the basis for SJRWMD projects to reestablish wetland connections to the IRL lagoon system. Activities to reconnect wetlands were started in 1990. Total reconnected acreage from 1990 to 2005 was approximately 29,389 acres (Brockmeyer, 2005). The ultimate goal is the reconnection of 33,000 acres (Steward et al., 2003). Much of the reconnected acreage was accomplished as part of the IRL SWIM Plan (19,703 acres). The remaining 9,686 acres of wetlands were reconnected by non-SWIM or private initiatives including local governments and the Merritt Island National Wildlife Refuge. The question of how reconnected impoundments within the Merritt Island National Wildlife Refuge will be managed spurred the creation ofthe three-year-long Wetlands Management Research Initiative. Impoundments are closed for long periods of eight months or more as a waterfowl and bird management technique. This closure prevents water exchange with the estuary, removes access by fish, and negatively affects invertebrate and plant communities. An alternate technique known as rotational impoundment management opens the impoundments for eight or nine months, but requires closure during the summer months for mosquito 

# 65 Water Quality Assessment Report: Indian River Lagoon

# control. The Wetlands Management Research Initiative is addressing

the benefi ts and drawbacks to different management techniques with the goal of proposing the best management technique or mix of techniques. Costs for the initiative are shared by SJRWMD, the Department’s Bureau of Survey and Mapping, U.S. Geological Survey, U.S. Fish and Wildlife
Service, EPA, and other entities involved in research. Several different techniques are used to vegetate and recreate shoreline habitat. Between 1991 and 1995, red and black mangroves ( Rhizophora mangle and Avicennia germinans ) and smooth cordgrass (Spartina alternifl ora) were planted on spoil islands in Indian River and Brevard Counties, on the delta at the end of South Relief Canal in Indian River County, and near the boat ramp in the Sebastian Inlet Park. Survival at these siteswas generally less than 5 percent (Steward et al., 2003) with the exception of the South Relief Canal where plantings were protected from wind and waves. Later plantings of mangroves were done by planting the tree seedlings within the confi nes of a thin-walled PVC pipe. This technique is referred to as the Riley Encased Methodology after its inventor. By 2002, more than 10,000 mangrove seedlings had been planted at 28 sites (Steward et al., 2003). Much of the planting is done by volunteers through an interagency partnership and the Indian River County Environmental Learning Center. Other nonimpacted wetlands are targeted for purchase under the Blueways Program.

Muck Removal 

# The removal of muck deposits has been identified as one of the strategies that will result in substantial reduction of a source of nutrients and turbidity in the IRL lagoon system. The central lagoon is the primary target area, because it contains a large number of muck deposits. The Eau Gallie River and Sebastian River are scheduled for dredging of muck by 2010 (Steward et al., 2003). Earlier muck removal projects in Turkey Creek and Crane Creek have been completed. The FIND and the USACOE are cosponsors of a 10-year plan for the environmental maintenance dredging of the Intracoastal Waterway, which contains about 60 to 70 percent of the muck in the IRL Basin.

Stormwater Improvement Projects 

# Stormwater runoff is an important source of suspended solids and nutrient input to the IRL lagoon system. Since 1995 numerous stormwater

retrofi t projects have been undertaken to address stormwater issues in the basin. The individual planning unit assessments contained in Chapter 3

and Appendix C describe these projects in detail. General storm water management techniques have included installation of baffl e boxes to remove sediments and construction of stormwater treatment ponds to capture runoff. Phosphorus is typically adsorbed to particles, particularly

sediment. Additional tools for managing stormwater are stormwater management plans and stormwater master plans. For example, the city of Edgewater is preparing a stormwater master plan that will describe existing conditions and recommend improvement projects. Brevard County has completed 

# 66 Water Quality Assessment Report: Indian River Lagoon

# stormwater management plans for the Upper Eau Gallie River and Crane Creek. Many other local governments in the basin have also prepared stormwater management plans. Some funding for local stormwater improvement projects has beenprovided from the sale of the IRL specialty license plate, which was established by the Florida legislature under Section 320.08058(10), F.S., and

fi rst issued in 1995. Revenue from sales of the plate is returned to the
Volusia, Brevard, Indian River, St. Lucie, and Martin Counties based on their proportion of plate sales. Revenue generated from license plate sales is distributed as not more than 20 percent for education projects and the remaining 80 percent for water quality and habitat restoration projects (SJRWMD, 2004). Local governments and nonprofi t organizations are eligible to apply for funds, but must be able to provide at least 25 percent of the total project cost as matching funds (SJRWMD, 2004). More than $3 million has been raised by tag sales with annual average revenue of
about $400,000. Many of the local governments in the basin also provide stormwater management and retrofi t funds from stormwater utilities.

# 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 Indian River Lagoon (IRL) Basin conducted by the Florida Department of Environmental Protection (Department). The primary purpose of the assessment was to determine if waterbodies or waterbody segments were to be placed on the Verifi ed List of impaired

waters. The assessment was conducted in accordance with evaluation

thresholds and data suffi ciency and data quality requirements contained in

the Identifi cation of Impaired Surface Waters Rule (IWR) (Rule 62-303,
Florida Administrative Code [F.A.C.]). The results of the assessment were 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 IRL Basin on which

the assessment was based. The Assessment by Planning Unit section ofthis chapter provides descriptions of each planning unit as well as summaries of the key water quality indicators in each unit, 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 assessment 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 in this chapter, it is 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 provides supplemental ecological information for the IRL Basin. Appendix C provides an overview of water quality improvement and habitat restoration projects in the IRL Basin. Appendix D provides additional

information on reasonable assurance. Appendix E provides the methodology used to develop the Planning and Verifi ed Lists. The complete text of the IWR is available at http://www.dep.state.fl .us/legal/Rules/shared/ 62-303/62-303.pdf. Appendix F contains the water quality assessment
Master List summary (Table F.1) and the water quality monitoring stations used in the assessment (Table F.2)

. Appendix G lists, by planning

Appendix H lists Level I land use by planning unit. Appendix I lists statistical summary sheets for ground water evaluations in

the IRL.



# 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 Central District staff and included both chemical and biological monitoring and data upload to STO rage and RET rieval (STORET) databases. Data gathering activities included working with environmental monitoring staff in the St. Johns River Water Management District (SJRWMD) and local and county governments to obtain applicable monitoring data from their routine monitoring programs and special water quality projects in the basin. Nine waterbody segments on the Planning List and the 1998 303(d) list needed further data to verify impairment. Parameters included copper, DO, nutrients (chlorophyll a and historical chlorophyll), silver,

and thallium. Sixty-eight waterbody segments were verifi ed impaired for at least one parameter in the IRL Basin as the result of strategic monitoring and data-gathering activities in Phase 2. Table F.1 in Appendix F provides the updated impairment status of the basin through June 30, 2006.



# Sources of Data

The assessment of water quality in the IRL Basin includes an analysisof 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 modern STORET databases, the U.S. Geological Survey, 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, local governments, and volunteer monitoring groups. Appendix E 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 IRL Basin for the planning and verifi ed periods of record used in this assessment. Major data providers were SJRWMD, Florida Department of Agricultural and Consumer Services (DACS) and

the Marine Resources Council. Figure 3.1 shows the amount of data provided by each source in each year of the planning and verifi ed periods.

# Indian River Lagoon Data Providers 

# 71 Water Quality Assessment Report: Indian River Lagoon

# In 2002, the Department created the IWR Database to evaluate data in accordance with the methodology prescribed in the IWR. For the Planning List assessment, the data evaluation period of record is 10 years, and for the Verifi ed List it is 7.5 years. Table E.2 in Appendix E 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 IRL 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 its description of designated uses. Because the Department is required to provide use attainment status for both the state’s 305(b) report and thestate’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

# 72 Water Quality Assessment Report: Indian River Lagoon

# 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 (Wayland, 2001). Following the EPA’s guidance, the Department delineated water bodies 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 report integrates the 303(d) list and the 305(b) report for the IRL Basin; it 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 waterbodiesor 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 93 waterbodies or waterbody segments in the IRL Basin, none are in Category 1. More waterbodies and segments statewide fall into Category 2 (attaining some uses but with insuffi cient data to assess completely) thanCategory 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. No waterbody segments in the IRL Basin fall into Category 2. Most waterbodies in the state, however, fall into Category 3 (having

insuffi cient data). In the IRL Basin, the breakdown of waterbodies or segments in Category 3 is as follows:

• Category 3a—No segments for which absolutely no data were available to determine their water quality status;

• Category 3b—16 segments with some data, but insuffi cient data for making any determinations; and

• Category 3c—9 potentially impaired segments based on 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. 

# 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 unknown causes, are listed under Category 4c. Although TMDLs are not established for Category 4c
waterbodies, these waterbodies still may be addressedthrough a watershed management program (for example, the Kissimmee River restoration).

may be listed as impaired at the end of Phase 2 of the watershed management cycle. However, the data have not yet been fully evaluated and
the 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. 

# 74 Water Quality Assessment Report: Indian River Lagoon

# Currently, no 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—No segments 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—No 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, 68 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 IRL Basin encompasses approximately 1,410 square miles and a complex hydrologic system. To provide a more detailed geographic basis for identifying and assessing water quality improvement activities, the basin 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 help organize 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. Although WBIDs often encompass several waterbodies, water quality data usually refl ect conditions within the main waterbody within a polygon. In some instances, however, the data from several waterbodies within the polygon have been aggregated. As the water quality assessments

are refined in Phase 2 of the watershed management cycle, individual waterbodies within these aggregations that have unique water quality concerns will be assigned unique WBIDs and evaluated individually. 

# 75 Water Quality Assessment Report: Indian River Lagoon

# The IRL Basin contains fi ve planning units: Mosquito Lagoon,
Banana River, North IRL, North Central IRL, and South Central IRL. Figure 3.2 shows the locations and boundaries of each planning unit. Descriptions of each planning unit are provided in the Assessment by Planning Unit section of this chapter, along with information on land uses 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 F contains the water quality assessment Master List summary (Table F.1) and the water quality monitoring stations used in the

assessment (Table F.2) by planning unit. Appendix G lists, by planning unit, permitted wastewater treatment facilities in the basin that dischargeto surface water and ground water, as well as hazardous waste sites, landfi lls, and brownfi elds. Appendix H lists Level I land use by planning unit.



# Seagrass Assessment

Seagrass assessment in the IRL lagoon system was conducted by comparing the existing seagrass depth limit to the target depth limit, which was

defi ned in the Pollutant Load Reduction Goal (PLRG) developed by the SJRWMD (Steward and Green, 2006). Impairment was identifi ed if the existing seagrass depth limit was shallower than the target depth limit. To conduct the seagrass assessment, SJRWMD divided the IRL lagoonsystem into several geographically, morphometrically, and hydrodynamically distinct regions (sublagoons) including the Banana River Lagoon (BRL), North Indian River Lagoon (North IRL), and Central Indian River Lagoon (Central IRL). (Please note that these sublagoon delineations are not related to the planning unit delineation used in the Department’s water quality assessment.) Mosquito Lagoon was not included in the PLRG analyses because seagrass coverage of the lagoon did not change suffi ciently

for the identifi cation of a causative pollutant. The North IRL, Central IRL, and BRL sublagoons were further divided into segments (Figure 3.3) . Several factors were considered in setting segment boundaries (Steward and Green, 2006). The primary factor was the presence of causeway bridges (13) that cross the IRL lagoon system, where disruptions in hydrodynamic circulation patterns have either been observed or presumed to exist (Evink, 1980), and where changes in seagrass coverage patterns were apparent (Virnstein, Steward, Morris, and Beck, 2003). Large island groupings, cuspate spits, and major tributaries were also considered in setting boundaries. Final segmentation was based on spatial analyses of water quality data through principal component analysis (PCA), and cluster and kriging analyses. PCA identifi ed turbidityand salinity as the principal variables responsible for inter-segment variability. Contiguous segments were aggregated if no signifi cant turbidity and salinity differences were found between them (via kriging and cluster analysis by Sigua, Steward, and Tweedale, 1996). The fi nal outcome was an IRL-BRL system divided into 15 segments as shown in Figure 3.3 (Steward, 2006).

# 77 Water Quality Assessment Report: Indian River Lagoon

# Figure 3.3: Locations of Seagrass Assessment Segments in the Indian River Lagoon Basin 

# 78 Water Quality Assessment Report: Indian River Lagoon

# Seagrass depth limits were determined from depth measurements obtained from a 1996 bathymetric data set developed by Coastal Planning & Engineering (1997). Depth measurements closest to a segment’s seagrass deep-edge boundary in a given year were selected as the depth limit for theyear using a set of rules that served to capture only the appropriate bathymetric data and exclude other data that could create erroneous depth limits (e.g., near or within dredged areas and the shallow edges of seagrass beds)
(Steward, Virnstein, and Morris, 2005). A seagrass full restoration target is based on the union of all themapped seagrass coverages available from 1943 to 1999, which encompassed every area where seagrass had been mapped (Steward et al.,
2005). The fi nal seagrass full restoration target was established as a 10 percent departure from the deep-edge boundary delineating this union coverage. The basis for the 10 percent departure was Florida’s water transparency standard (Rule 62-302.530, F.A.C.), which stipulates that the “depth of the compensation point for photosynthetic activity [as it relates to seagrass depth limits in this case] shall not be reduced by more than 10 percent as compared to the natural background value.” Naturalbackground is defi ned as “the condition of waters in the absence of maninduced alterations based on the best scientifi c information available” (Rule62-302.200[15], F.A.C.). Natural background values for water transparency are relevant in this case. Using the assessment method described above, none of the PLRGsegments in the IRL-BRL subbasins, and therefore none of the Department’s WBIDs in these areas, met the seagrass full restoration target (Figure 3.3a) . Based on previous studies, the major pollutants responsible for this depression were total suspended solids (TSS) and the nutrients total nitrogen and total phosphorus (Steward, Brockmeyer, Gostel, Sime, and Van Arman, 2003; Hanisak, 2001). All of the WBIDs in the IRL lagoon system were deemed impaired for nutrients.



# Fish Consumption Advisories

The DOH has issued several fi sh consumption advisories that affect the IRL Basin. The advisory for pufferfi sh recommends that pufferfi sh caught
in the IRL or coastal waters of Brevard, Indian River, Martin, St. Lucie, and Volusia Counties not be consumed (DOH, 2005). The advisory was issued because of the presence of saxitoxin in pufferfish tissue, including northern, southern, marbled, bandtail, checkered, and least pufferfi shspecies (DOH, 2005). In 2002, numerous people became ill after consuming pufferfi sh caught in the lagoon, and the source of the saxitoxin was suspected to be a native alga, but this has not been confi rmed (SJRWMD, 2005b). Saxitoxin poisoning can lead to neurological symptoms such as tingling, burning, numbness, incoherent speech, diffi culty in breathing,
and in rare extreme cases, death. The Florida Fish and Wildlife Conservation Commission prohibits the harvest of pufferfi sh. Consumption guidelines were issued for a substantial number of other

marine and estuarine fi sh in coastal waters of Florida, including those in

# Assessment by Planning Unit

• Banana River Planning Unit

General Description 

# The Banana River Planning Unit covers about 327.7 square miles inBrevard County and extends from just south of the A. Max Brewer Memorial Parkway near Titusville, south to the Eau Gallie Boulevard Causeway near Eau Gallie. It contains 14 waterbody segments (WBIDs). Major waterbodies in the planning unit include the Banana River and the coastal Atlantic beaches and nearshore coastal waters. Sykes Creek is a tributary to the planning unit. Major cities in the planning unit include Cocoa Beach, Satellite Beach, and Cape Canaveral. Patrick Air Force Base is located near the southern end of the planning unit, while Cape Canaveral Air Force

Station is located near the northern end.

Water Quality Summary 

# Of the 14 waterbody segments in the Banana River Planning Unit, 14 segments have suffi cient data for assessment. Of these, 14 are verifi ed impaired for at least one parameter assessed, none remain on the Planning
List, and none meet standards.Data from 110 water quality monitoring stations were used for evaluation of impairment. Figure 3.4 , a composite map of the planning unit, shows waters on the 1998 303(d) list, the Planning List and Verifi ed List, and potential pollution sources. Table 3.4 summarizes the water quality assessment status of all waterbody segments in the planning unit. All of the waterbody segments in the planning unit are impaired for mercury in fi sh. Several studies and reports have noted that historically thesouthern part of the Banana River, near Patrick Air Force Base, has consistently had high sediment and water column concentrations of trace metals (Trefry, Metz, Trocine, Iricanin, Burnside, Chen, Webb, 1990; Trocine and Trefry, 1993; Hand and Paulic, 1992, as referenced in Woodward-Clyde
Consultants, 1994b).

# Noncoastal Banana River waterbody segments are also impaired for DO and nutrients. The assessment of nutrient impairment in thesesegments was based on seagrass information (other information). Average annual loadings of nutrients and TSS (based on 1995 estimates) from nonpoint sources have more than doubled since 1942 (Steward et al., 2003). A large portion of the loading increase is attributed to the central and southern parts of the Banana River (Seagrass Assessment Segments BR 3–7). Water quality improvement projects and activities that will result in decreased loadings are summarized in the Water Quality Improvement Plans and Projects section.

Permitted Discharges and Land Uses



# Point Sources: There are 25 permitted wastewater discharges in the planning unit, 1 hazardous waste site, and 4 landfi lls. Of the wastewater discharges, 8 are domestic wastewater and 17 are industrial wastewater. 

# 84 Water Quality Assessment Report: Indian River Lagoon

# The largest National Pollutant Discharge Elimination System (NPDES) wastewater discharger is Cocoa Beach (6 million gallons per day [mgd]) followed in size by Cape Canaveral (1.8 mgd). Several industrial facilities (7) are also permitted for stormwater discharges. A Cocoa Beach Gasoline Contamination site was delisted in September 1988 (Department, 2005a) after removal of contaminants under the State Waste Cleanup Program. The site was determined to be contaminated in 1984 with gasoline and petroleum products (benzene, xylene, and toluene) from leaking gasoline tanks at a nearby car wash. There is one active sludge disposal landfi ll at Cape Canaveral Air Force

Station. Other landfi lls in the planning unit receive seafood processing waste and land clearing debris, and one is a garbage transfer station. Figure 3.4 shows the locations of these discharges in the planning
unit (see Noteworthy for a defi nition of point sources and a discussion of
environmental remediation). Appendix G lists the basin’s domestic and industrial permitted discharge facilities, along with their permitted fl ows, by planning unit. It also lists landfills or solid waste facilities and Superfund sites by planning unit (see Noteworthy: Environmental Remediation for more information on the Superfund Program). Nonpoint Sources: Based on land use data collected and delineated from year 2000 aerial photography, almost 70 percent of the planning unit is covered by water and wetlands. Another 14 percent of the planning unit is range and upland forest, composed primarily of shrub, brushland, and xeric oak forest. About 12 percent of the planning unit is composed of residential, commercial, and light industrial land uses. Most residential development is at medium density (2 to 5 dwellings/acre) and high density (6 or more dwellings/acre). Canaveral Air Force Base and the Kennedy Space Center cover about 4 percent of the planning unit. Table H.1 in Appendix H provides summary information on Level I land uses in the planning unit. Different land uses are associated with nonpoint source pollutant discharges and eroded sediments (see Noteworthy for a definition of nonpoint sources). In urban areas, stormwater discharges are managed through municipal separate storm sewer system (MS4) permits. Cocoa Beach, Satellite Beach, Patrick Air Force Base, and Cape Canaveral have Phase 2 MS4 permits.

Ecological Summary 

# Evaluation of the condition of seagrass communities revealed that seagrass coverage was stable in the planning unit throughout the 1990s. A shift in the composition of the seagrass community occurred in the Banana River in the later 1990s during a period of low salinity concurrent with a period of high rainfall. Syringodium fi liforme decreased in abundance while Ruppia maritime increased during that time period.Drift macroalgae are found in the central segments in greater abundance than other segments of the Banana River. Macroalgae utilize nutrients that would otherwise be available to phytoplankton, thus limiting phytoplankton growth (Davis, Zimmermann, and Montgomery, 1983). 

# 85 Water Quality Assessment Report: Indian River Lagoon

# Point sources discharging pollutants to surface water or ground water originate from discrete, well-defined areas such as a facility discharge from the end of a pipe, a disposal well, or a wastewater sprayfield.

Water Quality Improvement Plans and Projects 

# Numerous water quality improvement and habitat restoration projects have been undertaken or are currently planned in this planning unit (Appendix C) . Financial support for projects described in this section has come from the Department, SJRWMD, Brevard County Storm water Utility Department, local governments, and the Indian River Lagoon National Estuary Program (IRLNEP). Information summarized in thissection was obtained from the IRL Surface Water Improvement and Management (SWIM) Plan (Steward et al., 2003), Brevard County Stormwater Utility Program (Powers, 2006), and by personal communication with Bob Day with the IRLNEP (2005). Stormwater retrofi t projects discussed cover the period from 1995 to 2005. Brevard County and many of its municipalities have completed or have under way numerous projects that better manage stormwater runoff. Cape Canaveral, Cocoa Beach, and Satellite Beach are preparing surface water management plans as a means to more fully address stormwater issues in their respective communities. The following describes many of the local projects implemented or under construction in the planning unit.

• Satellite Beach: Satellite Beach has completed the installation of

permeable pavement and an exfi ltration trench on Wilson Avenue.

Exfiltration trenches installed on Jackson Avenue will treat stormwater from 20 acres and also decrease the frequency of fl ooding in the area. Three wet detention ponds in the Jamaica Boulevard area

have been constructed to treat runoff from 201 acres of the DeSoto Parkway watershed. Installation of baffl e boxes is also planned

for this watershed. Baffl e boxes have been installed for a 20-acre residential development on Roosevelt Avenue and are planned for

Grant Avenue to treat a 96-acre watershed.

• Merritt Island and other unincorporated areas: Brevard County

has connected about 75 residences and businesses located in Merritt Park Place to central sewer. Brevard County is responsible for stormwater management on Merritt Island. The county has plans to divert a ditch on the Merritt Island Airport from the Banana River into a regional detention pond. The county has installed curb and grate inlet baskets in storm drains on Merritt Island, some with oil absorption pillows, to reduce the amount of trash reaching the Banana River and the northern part of the IRL, while in residential

areas baffle boxes have been installed to reduce sediments entering the IRL. The county has secured funds to install an additional

8 to 10 baffl e boxes over the next 4 years to reduce sediment loads from Merritt Island to the IRL. The county also constructed the Merritt Ridge Alum Treatment Plant to treat stormwater runoff from 314 acres of residential, commercial, and industrial development. 

# 87 Water Quality Assessment Report: Indian River Lagoon

# Funds from a federal 319(h) grant provided partial fi nancial supportfor the construction of a detention pond located at Florida Boulevard. County stormwater utility funds were used to construct a second pond on South Tropical Trail Lane. The Florida Boulevard pond will treat 178 acres of residential and commercial development and the Tropical Trail Lane pond will treat 35 acres of residential development.

• South Patrick area: Brevard County, using stormwater utility

funds, has completed construction of a two-acre regional detention pond at the abandoned Sea Park Sewer Plant in the South Patrick area. Accompanying the detention pond are soccer fi elds, a park, and playground. Water detained in the pond is used to irrigate the

soccer fi elds.

• North Merritt Island: Brevard County has initiated the Lake

George Water Quality Improvement Project. This project willreroute an existing agricultural discharge and direct it to two stormwater ponds and wetland treatment areas prior to discharge into the IRL/Banana River through the barge canal.

• Cape Canaveral: Cape Canaveral has installed a Continuous

Deflective Separation unit to trap sediment in runoff from the property of the city’s wastewater treatment plant facility. A second baffl e box was installed at International Drive that treats a 195-acre urban

watershed.

• Cocoa Beach: Cocoa Beach has installed inlet baskets in storm

drains to prevent debris from entering the storm sewer. The city has also constructed a bioretention facility on Brevard Avenue to serve

an old downtown area. A baffl e box has been installed at Second Street South to capture sediments from an approximate 10-acre basin. There are plans for a detention pond at Maritime Hammock Preserve that will use alum treatment as part of a pollutant removal system. This system will serve an 80-acre watershed.

Restoring habitat to the Banana River is an important component in the overall rehabilitation of the IRL lagoon system. About 1,967 acres of wetlands, mostly in the Sykes Creek/Newfound Harbor area, are included in the Blueway land acquisition project. Two separate mangrove plantings were accomplished at Kelly Park on Merritt Island during 1997 and 1998. There are 5,079 acres of impounded wetlands in the planning unit;
about half that total (2,490 acres) has been breached or reconnected to the Banana River (Brockmeyer, 2005). Most of the reconnected acreage is located in the Sykes Creek watershed and was reconnected as part of a mitigation project (Steward et al., 2003). About 2,589 remaining acres of impounded wetlands are targeted for reconnection in the future (Steward et al., 2003; Brockmeyer, 2005). There are also about 430 acres of dragline-impacted wetlands in the planning unit. A workplan for restoration of this acreage is in development
(Steward et al., 2003).

• Mosquito Lagoon Planning Unit

General Description 

# The Mosquito Lagoon Planning Unit covers about 266.8 square miles in Volusia and Brevard Counties and extends from just north of Ponce de Leon Inlet near New Smyrna Beach, south just past the A. Max Brewer Memorial Parkway near Titusville. It contains 14 waterbody segments (WBIDs). Major waterbodies in the planning unit are Mosquito Lagoon

and the coastal Atlantic beaches and nearshore coastal waters. Cities located in the planning unit include Oak Hill, Edgewater, and New Smyrna Beach.

Water Quality Summary 

# Of the 14 waterbody segments in the Mosquito Lagoon Planning Unit, 13 segments have suffi cient data for assessment. Of these, 13 are verifi ed impaired for at least 1 parameter assessed, none remain on the Planning
List, and none meet standards. Data from 65 water quality sampling stations were used for assessment of impairment. Figure 3.5 , a composite map of the planning unit, shows waters on the 1998 303(d) list, the Planning List and Verifi ed List, and potential pollution sources. Table 3.5 summarizes the water quality assessment status of all waterbody segments in the planning unit. The southern part of Mosquito Lagoon (WBID 2924) is impaired for DO and mercury in fi sh. All other waterbody segments in the planning unit are impaired for mercury in fi sh only. Average annual nonpoint source loadings of TSS and nutrients (based on 1995 estimates) have increased by a factor of 1.5 in Mosquito Lagoon when compared with 1943 loadings (Steward et al., 2003). Water quality improvement projects and activities that will result in decreased loadings

are summarized in the Water Quality Improvement Plans and Projects

section.

Permitted Discharges and Land Uses



# Point Sources: There are six permitted point source discharges in the planning unit, with three being landfi lls. Of the three landfi lls, two are active solid waste transfer stations located in Edgewater and New Smyrna

Beach. The Oak Hill Landfi ll is closed. There are no hazardous waste sites or ground water contamination areas in the planning unit. The largest point source discharge in the planning unit is 7 mgd from the New Smyrna Beach Reclamation Facility and the 2.25 mgd NPDES discharge from the Edgewater wastewater treatment plant.

# two domestic, two industrial, and one concrete batch plant discharges are less than 0.05 mgd. Figure 3.5 shows the locations of these discharges in the planning

unit. Appendix G lists the basin’s domestic and industrial permitted discharge facilities, along with their permitted fl ows, by planning unit. It

also lists landfi lls or solid waste facilities and Superfund sites (EPA, 2007a) by planning unit. Nonpoint Sources: Based on land use data collected and delineated from year 2000 aerial photography, about 82 percent of the planning unit is water and wetlands. Residential, commercial, and light industrial usescover another 6.5 percent of the planning unit. Most residential development is medium and high density. Conservation and recreation lands in the planning unit include Canaveral National Seashore and Park, New Smyrna Dunes State Park, Riverbreeze Park, Bethune Beach Ocean, and

River Park. Table H.2 in Appendix H provides detailed information on land uses in the planning unit. Different land uses are associated with nonpoint source pollutant discharges and eroded sediments. In urban areas, stormwater discharges are managed through MS4 permits.

Ecological Summary 

# The southern part of Mosquito Lagoon contains one of the more extensive seagrass coverages in the IRL lagoon system, with little change observed since 1943. The area of Mosquito Lagoon with the least coverage and greatest loss of seagrass since 1943 is the northernmost area near New Smyrna Beach. This area has experienced as much as a 94 percent loss of seagrasses. The current condition of seagrass beds in this planning unit is

further assessed and summarized in the Seagrass Assessment section of 

# 92 Water Quality Assessment Report: Indian River Lagoon

# this chapter based on information provided by SJRWMD (Steward and
Green, 2006). Unlike more southern parts of the IRL lagoon system, generally little muck is found deposited in Mosquito Lagoon (Steward et al., 2003). The muck is easily resuspended, resulting in increased turbidity, reduced light penetration, increased oxygen demand, and release of nutrients to the

water column.

Water Quality Improvement Plans and Projects 

# Habitat restoration and numerous water quality improvement projects have been undertaken or are currently planned in this planning

unit (Appendix C) . Financial support for projects has come from the SJRWMD, local governments, and the IRLNEP. Information summarized about example projects in this section was obtained from the IRL SWIM Plan (Steward et al., 2003) and by personal communication with Bob Day
with the IRLNEP (2005). Stormwater retrofi t projects discussed cover the time period from 1995 to 2005.New Smyrna Beach has made substantial progress with the management of both wastewater discharges and stormwater runoff. The city has completed construction of a wastewater treatment plant located west of Interstate 95. The plant includes up to a 6 mgd capacity reuse system,which will account for most of the plant’s discharge. Wet weather discharge from the plant is still permitted. Several stormwater management plans and projects have been completed or are in development within New Smyrna Beach. The city installed baffl e boxes at the intersection of Riverside and Wayne Avenues in 1997 and 1998 to prevent sediments from entering Mosquito Lagoon. Several sediment traps have been installed in the drainage system along Riverside and Magnolia Avenues. The city is also doing a stormwater retrofi t at the New Smyrna Beach Marina. This

retrofi t requires use of a baffl e box to capture runoff from three existing outfalls. New Smyrna Beach also has projects pending to install baffl e boxes at Quay Assisi and upgrading drainage at East Circle. The city of Edgewater is preparing a Stormwater Master Plan. The city has plans to construct a 2.25 million gallon storage tank that will hold reclaimed water during wet weather. The water can be used for irrigation in dry weather. Edgewater has undertaken the installation of baffl e boxesat Mango Tree Drive and Gabordy Canal to reduce the amount of sediment entering Mosquito Lagoon. The city of Oak Hill has completed a stormwater master plan for the city. This plan includes several projects that when constructed will reduce pollutant loadings to Mosquito Lagoon.Restoring wetland habitat in Mosquito Lagoon is an important component in the overall rehabilitation of the IRL lagoon system. The Volusia Soil and Water Conservation District has received funding to plant red mangroves and cordgrass at fi ve locations in the Canaveral National Seashore property. About 5,100 acres of mosquito impoundments have been reconnected or restored in this planning unit (Brockmeyer, 2005). The University of Central Florida and The Nature Conservancy have recently initiated a 

# 93 Water Quality Assessment Report: Indian River Lagoon

# project to restore several acres of oyster bars in Mosquito Lagoon using mats with attached oyster shells. Waters will not be placed on the Verifi ed List if the Department receives reasonable assurance that existing or proposed projects and/ or programs are expected to result in the attainment of water quality standards or consistently improve water quality over time. Appendix D contains more detailed documentation of the requirements for reasonableassurance. For this planning unit, no management plans or projects complying with the Department’s guidance for reasonable assurance have been provided for the list of impaired waters.

• North Indian River Lagoon Planning Unit

General Description 

# The North IRL Planning Unit covers about 281.2 square miles in Volusia and Brevard Counties and extends from just south of New Smyrna Beach near the community of Edgewater, south to Horse Creek located north of Eau Gallie. It contains 9 waterbody segments (WBIDs). Major waterbodies in the planning unit are the Indian River Lagoon and Banana Creek. Tributaries to the planning unit are Turnbull Creek, Addison Creek, and Horse Creek. Haulover Canal connects Mosquito Lagoon to the northern part of the IRL. Major cities in the planning unit are Cocoa, Rockledge, and Titusville.

Water Quality Summary 

# Of the nine waterbody segments in the North IRL Planning Unit, nine segments have suffi cient data for assessment. Of these, six are verifi ed impaired for at least one parameter assessed, three remain on the Planning
List, and none meet standards.Data from 243 water quality monitoring stations were used for assessment of impairment. Figure 3.6 , a composite map of the planning unit, shows waters on the 1998 303(d) list, the Planning List and Verifi ed List, and potential pollution sources. Table 3.6 summarizes the water quality assessment status of all waterbody segments in the planning unit. Five of the nine waterbody segments of this planning unit are impaired for mercury in fi sh. Fish consumption advisories have been issued for the IRL from the Melbourne Causeway north to the A. Max Brewer Memorial Parkway. Other metals impairments in the unit include copper and nickel. Studies and reports have noted that historically the portion of the planning unit between Titusville and Cocoa has consistently had high sediment, water column, and marine organism tissue concentrations of trace metals (Trefry et al., 1990; Trocine and Trefry, 1993; Hand and Paulic, 1992, as referenced in Woodward-Clyde Consultants, 1994b). Trocine and Trefry (as referenced in Woodward-Clyde Consultants, 1994b) noted elevated levels of copper and trace metals in clam tissue collected adjacent to parts of the IRL. This area includes hard clam harvesting beds. Trocine and Trefry (1993) speculated that the source of dissolved copper in the water column was leachate from antifouling paints used on ships.

# 97 Water Quality Assessment Report: Indian River Lagoon

# The Indian River waterbody segments of the planning unit are impaired for nutrients, largely based on assessment of other information. Some segments are also impaired for DO.Average annual loadings of nutrients and TSS (based on 1995 estimates) have increased in the northern part of the IRL since 1943, though the increases are substantially lower than the central part of the IRL (Steward et al., 2003). Water quality improvement projects and activities that will result in decreased loadings are summarized in the Water Quality Improvement Plans and Projects section.

Permitted Discharges and Land Uses



# Point Sources: There are 29 permitted wastewater discharges,
2 hazardous waste sites, and 6 landfi lls in this planning unit.Of the 29 permitted wastewater discharges, 12 are industrial wastewater, 15 are domestic wastewater, 1 is from a concrete batch plant, and1 is a petroleum cleanup site. The largest industrial discharges are cooling water from the Reliant Energy (820 mgd) and Florida Power and Light (800 mgd) plants. The largest domestic wastewater discharges are from the Cocoa Water Reclamation Facility and Titusville North Water Reclamation Facility. The Weekley Lumber hazardous waste site is located in Rockledge. It is an active site that is being remediated under the State Waste Cleanup Program (Department, 2005b). Contaminants at this site are associated with wood preservation. Soils are contaminated with copper, chromium, and arsenic with some onsite leaching into the surfi cial aquifer. The Skipper’s III, Inc., hazardous waste site is located in Cocoa. It is also an active site that is being remediated under the State Waste Cleanup Program (Department, 2005c). Contaminants at this site are associated with electroplating. Elevated levels of arsenic and chromium were detected in onsite soils, and levels exceeding primary drinking water standards
for cadmium, chromium, lead, nickel, and thallium have been found in ground water. Soils have been removed from the site and a ground water monitoring plan has been implemented.

Of the six listed landfi lls, three are closed or inactive dump sites, one is for debris, one is for waste tire processing, and one is for special waste. Figure 3.6 shows the location of these discharges in the planning unit. Appendix G lists the basin’s domestic and industrial surface discharge facilities, along with their permitted fl ows, within the planning unit. It also lists Superfund sites and landfi lls or solid waste facilities. Nonpoint Sources: Based on land use data delineated from 2000 aerial photography, more than 68 percent of the planning unit is water and wetlands. Urban and built-up land covers 11.3 percent of the planning unit’s area. Residential land use is a fairly equitable mix of low, medium,and high density residential. Commercial, institutional, and other industrial land uses occupy more than 1.7 percent of the planning unit. The Kennedy Space Center is located on north Merritt Island. Table H.3 in Appendix H provides summary and detailed information on land uses in the planning unit. 

# 98 Water Quality Assessment Report: Indian River Lagoon

# Different land uses are associated with nonpoint source pollutant discharges and eroded sediments. In urban areas, stormwater discharges are managed through MS4 permits. Cocoa, Rockledge, and Titusville all have MS4 Phase 2 permits.

Ecological Summary 

# Based on SJRWMD’s seagrass assessment index, seagrass coverage north of NASA Causeway is rated good to excellent (segments IR1–5). Overall ratings for these fi ve segments are good with no defi ciencies for any of the indicators based on 1991–1996 data. The current seagrass coverage is slightly larger in area when compared with seagrass coverage in 1943. The segment of the IRL immediately south of Titusville (IR5) is consistently ranked as one of the best with regard to total acreage and depth of seagrasscoverage. Though this part of the IRL is poorly fl ushed, it is comparatively less intensively developed than the more southern parts of the lagoon, which may be a positive benefi t for seagrasses. The areas with the poorest ratings for seagrasses are segments IR6–8, based on data from 1991 to1996. These segments are located in the more developed parts of the planning unit and are potentially subjected to greater variability in hydrology. More recent analysis of seagrass data collected from 1998 to 2003 indicated that segments IR6–8 have improved enough to be classifi ed as good, but segment IR3 has declined to a fair ranking (Steward, 2006). Although seagrass coverage in some segments was improved in the last decade, seagrass depth-limit in none of these segments has reached the full restoration target. Therefore, all of the mainstem waterbody segments in the North IRL Planning Unit were assessed as being impaired for nutrients based on seagrass information. The current condition of seagrass beds in this planning unit is further

assessed and summarized in the Seagrass Assessment section of this chapter based on information provided by the SJRWMD (Steward and
Green, 2006).

Water Quality Improvement Plans and Projects 

# Numerous water quality and habitat improvement projects have been undertaken or are currently planned in this planning unit (Appendix C)

.Financial support for projects has come from the SJRWMD, local governments, Brevard County Stormwater Utility, federal 319(h) grants, and the IRLNEP. Project information summarized in this section was obtainedfrom the IRL SWIM Plan (Steward et al., 2003), Brevard County Stormwater Utility Department (Powers, 2006), and by personal communication with Bob Day with the IRLNEP (2005). Stormwater retrofi t projects discussed cover the time period from 1995 to 2005. Brevard County has initiated or completed a number of stormwater improvement projects in the Titusville, Merritt Island, Port St. John, and

Scottsmoor areas.

• Titusville: Brevard County has constructed a stormwater weir at

the Kennedy Point Marina south of Titusville. The weir will collect sediments from a 320-acre drainage basin. 

# 99 Water Quality Assessment Report: Indian River Lagoon

# • Titusville area: Brevard County’s recently completed Chain of Lakes Regional Stormwater Treatment Facility provides stormwater

treatment for the fi rst fl ush of runoff from an 850-acre watershed. This project consists of a 40-acre lake constructed for stormwater

treatment and the reestablishment of 14 acres of wetlands that will treat stormwater from Titusville and unincorporated areas of Brevard County and relieve fl ooding from the Coleman Ditch. The project contains recreational and public education elements. Project partners are the SJRWMD, Brevard Community College, Parrish Medical Center, Brevard County Parks and Recreation, and Brevard County Stormwater Utility Department (Brevard County Stormwater Utility Department, 2006).

• Merritt Island and other unincorporated locations: On north

Merritt Island, the county is converting 2 large borrow pits located on Pine Island to function as stormwater treatment ponds. These ponds will serve a drainage basin of approximately 750 acres.

• Port St. John: Brevard County installed baffl e boxes at Sunrise Village and constructed detention ponds off Broadway Boulevard and at Port St. John Basin C/Albin Street and Port St. John Basin B/ Parrish Medical Center. The Broadway Boulevard Pond will treat

127 acres of residential area.

• Scottsmoor: Brevard County prepared a Master Stormwater Plan

for Scottsmoor in the early 1990s. The plan recommended the construction of stormwater ponds in the Scottsmoor area including the Huntington Road Pond, Flounder Creek Pond, and John’s Road Pond. These ponds were constructed to treat stormwater runoff from agricultural and residential land uses and relieve fl ooding.

The larger cities located in this planning unit have initiated additionalindependent or cooperative projects directed at the management of stormwater runoff. Rockledge has completed installation of baffl e boxes in the Rockledge Drive, Barton Avenue, and Orange Avenue areas and plans to

install another baffl e box at the corner of Rockledge Avenue and Rockledge Drive to trap sediments from more than an eight-acre drainage basin. The city has plans to install baffl e boxes at each stormwater outfall entering the IRL by 2010 (Day, 2005). The SJRWMD and Rockledge are partnering for the construction of a stormwater detention pond that will address flooding in the Fiske Boulevard area. The city of Titusville’s Garden Street Basin Stormwater Management project will treat a 114-acre watershed when completed. The project isbased on the treatment train concept of utilizing a number of best management practices (BMPs) together or in sequence to provide better storm water treatment. The project treatment train is composed of 3 swales, check dams, 8 inlet skimmers, and alum injection in a constructed treatment pond. Titusville has also completed a retention pond at Sand Point Park serving a portion of the Garden Street basin.

Cocoa has installed baffle boxes and an underground stormwater collection reservoir in Riverfront Park. Stormwater treated with this system is 

# 100 Water Quality Assessment Report: Indian River Lagoon

# generated in an older section of downtown. Instead of being discharged to the IRL lagoon system, stormwater collected in the reservoir is sent to the city’s wastewater treatment plant to supplement the supply of reuse water.Habitat restoration is an important component in the overall restoration of the IRL lagoon system. Large tracts of coastal mangrove wetlands were previously impounded for mosquito control. About 14,393 acres of these impounded coastal wetlands have been reconnected to the lagoon, largely through the SWIM Program, but about another 5,000 acres remainimpounded (Brockmeyer, 2005). Most of the remaining impounded wetlands are on federally owned property within the Merritt Island National Wildlife Refuge. Waters will not be placed on the Verifi ed List if the Department receives reasonable assurance that existing or proposed projects and/or programs are expected to result in the attainment of water quality standards or consistently improve water quality over time. Appendix D contains more detailed documentation of the requirements for reasonable assurance. For this planning unit, no management plans or projects complying with the Department’s guidance for reasonable assurance have been provided for the list of impaired waters.

• North Central Indian River Lagoon Planning Unit

General Description 

# The North Central IRL Planning Unit covers about 196.4 square miles in Brevard County and extends from just north of Melbourne, south to the St. Sebastian River near Micco. It contains 24 waterbody segments (WBIDs). Major waterbodies in the planning unit are the Indian River Lagoon and the coastal Atlantic beaches and nearshore coastal waters. Tributaries to the planning unit include the Eau Gallie River, Crane Creek, and Turkey Creek. Urbanized areas in the planning unit include Melbourne, Palm Bay, and the beachside communities of Melbourne
Beach, Indialantic, and Indian Harbour Beach.

Water Quality Summary 

# Of the 24 waterbody segments in the North Central IRL Planning Unit, 16 segments have suffi cient data for assessment. Of these, 12 are

verified impaired for at least 1 parameter assessed, 4 remain on the Planning List, and none meet standards.Data from 143 water quality monitoring stations were used for assessment of impairment. Figure 3.7 , a composite map of the planning unit, shows waters on the 1998 303(d) list, the Planning List and Verifi ed List, and potential pollution sources. Table 3.7 summarizes the water quality assessment status of all waterbody segments in the planning unit.

# Creek and the Eau Gallie River are believed to be a natural condition for which TMDLs will not be developed. All coastal waterbody segments in the planning unit are impaired for mercury in fi sh.
The mainstem waters of the Indian River (WBIDs 2963A and 2963B) are listed for nutrients based on seagrass information (other information). The Eau Gallie River, Crane Creek, Turkey Creek, and the Indian River above Melbourne Causeway are impaired for DO. Average annual loadings of nutrients and TSS have shown substantial increases since 1943. The estimated 1995 annual loadings of TSS and nutrients are 3 to 6 times higher than the North IRL and 6 to 15 timeshigher than either Banana River or Mosquito Lagoon. Tributary watersheds contribute a substantial portion of the nutrient and TSS loads. The Crane Creek watershed has the highest areal loading rate (as pounds/ acre/year) of all the subbasins or watersheds in the IRL Basin. Loadings continue to increase as the watershed urbanizes. The pollutant loadings
from tributaries have had detrimental effects on the IRL (Steward et al., 2003). Water quality improvement projects and activities that will result in decreased loadings are summarized in the Water Quality Improvement Plans and Projects section.

Permitted Discharges and Land Uses



# Point Sources: There are 44 permitted point source discharges, 1Superfund site, 1 delineated ground water contamination area, and 4 landfi lls in this planning unit. Of the 44 permitted discharges in the planning unit, 19 are domestic wastewater, 14 are industrial wastewater, 5 are from concrete batch plants,and 6 are industrial stormwater. The largest domestic wastewater discharges in the planning unit are 8 mgd from the Brevard County Utilities South Beaches facility, 5.5 mgd from the Melbourne Grant Street facility, and 5.0 mgd from the D. B. Lee facility.An active Superfund site is located in Palm Bay. The Harris Corporation Superfund site is listed because volatile organic compounds used in 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

# steel, metal, and electrical processing were found in ground water supply wells in the General Development Utilities Port Malabar wellfi eld. The sitewas placed on the National Priorities List (NPL) in July 1987 and is undergoing remediation to remove organics from ground water (Department,
2005d). The four landfi lls are located in Melbourne. Two are active solid

waste transfer stations and the others are closed landfi lls. Figure 3.7 shows the locations of these discharges in the planning

unit. Appendix G lists the basin’s domestic and industrial surface discharge facilities, along with their permitted fl ows, by planning unit. It also lists Superfund sites and landfi lls or solid waste facilities by planning unit. Nonpoint Sources: Based on land use data collected and delineated from 2000 aerial photography, water and wetlands cover more than 55 percent of the planning unit. Urban and built-up land uses occupy 24.6 percent of the basin’s area. High and medium density residentialhousing account for more than half of the urban land uses in the planning unit. Other land uses include upland forest (8.8 percent), represented largely as pine fl atwoods (8.5 percent) and rangeland (0.3 percent).

Table H.4 in Appendix H provides detailed summary information on land uses in the planning unit. Different land uses are associated with nonpoint source pollutant discharges and eroded sediments. In urban areas, stormwater discharges are managed through MS4 permits. Melbourne, West Melbourne, Satellite Beach, Indian Harbour Beach, Indialantic, and Palm Bay are covered under Phase 2 of MS4 permitting.

Ecological Summary 

# The condition of seagrasses in this planning unit is generally poorer than in the more northern planning units. Some of the poorest conditions and coverage of seagrasses in the IRL system are found in the Melbourne area (segments IR9–12), based on 1991–1996 data. Much of this area of the IRL is poorly fl ushed and receives comparatively large infl ows of freshwater and pollutant loadings, factors that contribute to the poorer condition of seagrasses. The extent of seagrass coverage in this part of the IRL

fl uctuates more widely than in other sections of the lagoon.More recent analysis of seagrass data collected from 1998 to 2003 indicates that the condition of seagrasses in segments IR9–12 have improved enough to be ranked as fair (Steward, 2006). Segments to the south of Melbourne have improved enough to be ranked as good (Steward, 2006). Although seagrass coverage in some segments was improved in the last decade, the seagrass depth-limit in none of these segments has reached the full restoration target. Therefore, all of the mainstem waterbody segments in the North Central IRL Planning Unit were assessed as being impaired for nutrients based on seagrass information. The current condition of seagrass beds in this planning unit is further

assessed and summarized in the Seagrass Assessment section of this chapter based on information provided by the SJRWMD (Steward and
Green, 2006). Much of the muck deposited in the IRL, about 65 percent, is located in the central part of the lagoon (Steward et al., 2003). Studies by Trefry 

# 106 Water Quality Assessment Report: Indian River Lagoon

# et al. (1990) indicated that a substantial portion of the muck has been deposited over the past 40 years. Tributaries like the Eau Gallie River, Crane Creek, and Turkey Creek act as sediment traps and have over the years accumulated large deposits of muck. Additional muck has been deposited in the Intracoastal Waterway, other channels and turning basins, and dredged holes and causeway borrow pits. The muck at the bottom of the lagoon and its tributaries is easily resuspended, resulting in increased turbidity, reduced light penetration, increased oxygen demand, and release

of nutrients to the water column.

Water Quality Improvement Plans and Projects 

# Numerous water quality and habitat improvement projects have been undertaken or are currently planned in this planning unit (Appendix C)

. Financial support for projects was provided by the SJRWMD, Brevard County Stormwater Utility, local governments, and the IRLNEP. Project

information summarized in this section was obtained from the IRL SWIM Plan (Steward et al., 2003), Brevard County Stormwater Utility Program (Powers, 2006), and by personal communication with Bob Day with the IRLNEP (2005). Information about specific projects is organized by contributing tributary watershed. Stormwater retrofi t projects discussed cover the time period from 1995 to 2005. The Turkey Creek watershed is a substantial source of loading to the IRL lagoon system. The largest and most signifi cant load reduction project under way in the Turkey Creek watershed is the C-1 rediversion project. This project is expected to help Turkey Creek meet PLRGs for nutrient and suspended solids reductions (Steward et al., 2003). The purpose of the C-1 rediversion project is to divert the discharge

from Melbourne–Tillman Water Control District’s C-1 Canal westward toward the Upper St. Johns River Basin. The canal was built to extend the Turkey Creek watershed into the Upper St. Johns River Basin to drainmarshes with the result of creating suitable land for agriculture. Afterstorm discharges through the canal into Turkey Creek could reach 500mgd (Steward et al., 2003). The increased volumes of fresh water discharged through Turkey Creek to the IRL lagoon system caused a lowering of salinity in the lagoon, added large loads of nutrients, contributed

to the decline of the hard clam fi shery, and have had a negative impact on

seagrasses. The C-1 rediversion project is being constructed by the SJRWMD within the canal right-of-way of the Melbourne–Tillman Water Control District. Water returned to the St. Johns River will be stored in the C-1 Retention and Detention areas before being pumped into a created wetland treatment system, called the Sawgrass Lake Water Management Area, for treatment prior to release into the St. Johns River.The management of stormwater runoff is an important tool for reducing nutrient and sediment loads to Turkey Creek and ultimately the IRL lagoon system. The city of Palm Bay has undertaken numerous past and current stormwater management efforts to address the problems of nutrient and sediment loading. Improvements are proposed for the Perimeter Canal to reduce sediment discharges to the lower reach of Turkey Creek. TSS and 

# 107 Water Quality Assessment Report: Indian River Lagoon

# nutrient loads to Turkey Creek will be reduced with the completion of a series of 3 stormwater ponds and treatment of stormwater outfalls from the Turkey Creek subdivision. Treatment of runoff from subdivisions in Palm Bay (Palm Bay units 38 and 40) with ponds will add further reductions. The reduction of runoff from the Turkey Creek subdivision located along

the Mandarin Ditch will reduce fl ooding and erosion of the ditch banks. Additional stormwater improvement projects for the Turkey Creekwatershed were completed in the Palm Bay area before 2001. Wet detention ponds constructed in Basins 1 and 7 treat runoff from a 100-acre residential and commercial development. This project also treats runoff that discharges directly into the IRL lagoon system. Baffl e boxes wereinstalled on Norwood Street in Palm Bay and on Corey Road in neighboring Malabar. The Crane Creek watershed covers about 21 square miles and drains a developing urban area. Crane Creek receives stormwater runoff fromMelbourne, Melbourne Village, West Melbourne, and parts of unincorporated Brevard County. Brevard County’s Stormwater Utility Departmentcontracted the development of a stormwater master plan for this watershed and the Hickory Ditch watershed in 2002 (Post, Buckley, Shuh, and Jernigan, Inc. [PBS&J], 2002) with fi nancial support from Melbourne and SJRWMD (Brevard County Stormwater Utility Department, 2006). The plan helps to identify potential water quality BMPs, areas of the watershed

with fl ooding problems, and actions that could be used to increase ground water recharge. Design and permitting is currently under way for the St. Johns Outfall Project identifi ed in the report. This project consists of upgrading culverts and ditches to divert fl ow from the IRL lagoon system to the St. Johns River. An existing borrow pit will be modifi ed to provide treatment prior to discharge to the St. Johns River.

Stormwater retrofi ts are an important part of the overall strategy to reduce stormwater runoff and associated pollutant loads within the

Crane Creek watershed. Reduction of sediment loads to the M-1 Canal and ultimately Crane Creek will be achieved with the Melbourne VillageStormwater and Sediment and Erosion Control Project. A previous sediment control project in Melbourne’s Goode Park Terrace area resulted in the paving of dirt roads and the construction of swales to treat runoff from residential development. Brevard County had also previously treated andimproved drainage from Dove Street. The city of West Melbourne completed installation of a pipe in the Shannon Avenue ditch to reduce erosion in the ditch and prevent transport of sediment to the M-1 Canal. A baffl e box was constructed to treat the discharge of the pipe to collect sediment

before it could enter the M-1 Canal. A Stormwater Master Plan was completed for the Upper Eau Gallie River watershed in 2000 (PBS&J, 2000). The plan identifi ed areas ofthe watershed needing additional stormwater quantity and quality controls. As part of the execution of that plan, drainage improvements to

alleviate fl ooding have been made where Wickham Road crosses the Eau

Gallie River. The Wickham Park Detention Pond was constructed to treat

stormwater runoff. 

# 108 Water Quality Assessment Report: Indian River Lagoon

# Numerous other stormwater improvement projects initiated by Brevard County and local city governments are targeted at removing nutrient and sediment loads directly from the IRL lagoon system.

• Brevard County is utilizing a dry retention pond to treat residential

development on Barracuda Avenue in Melbourne Beach.

• The city of Melbourne Beach has plans for stormwater treatment

train methodologies at eight city street intersections as part of the Melbourne Beach Pedway Project. The city has also installed baffl eboxes on Ocean Drive to treat runoff from residential and commercial development.

• In the Melbourne Beach area, the Brevard County Storm water

Utility Department assisted Gemini Elementary School with construction of dry retention ponds and swales.

• Brevard County has completed construction of a stormwater pond

and wetlands to treat runoff from Melbourne Shores prior to discharge to the lagoon.

• Indialantic has constructed a swale system between Fourth Avenue

and Indian River Drive to treat runoff from 30 acres of medium-tohigh density residential land use and purchased a street sweeper.

Muck accumulated in parts of the IRL lagoon system contributes nutrients and resuspended sediment to the water column. Eliminating muck deposits from the waters of this planning unit will help restore water quality and improve the biological condition of seagrasses in the IRLlagoon system. The strategy to handle muck is twofold: remove existing large accumulations and prevent further upland erosion of sediments. Many of the aforementioned stormwater improvement projects address the second part of this strategy by reducing soil erosion. Muck deposits were removed from Crane Creek in 1998 and from Turkey Creek in 2001. A conceptual dredge removal and disposal plan was completed for the Eau Gallie River. Other parts of the planning unit that are under consideration for muck removal projects include the Intracoastal Waterway and a 10-mile stretch of the lagoon from about the Eau Gallie Causeway (State Road 518) south to Turkey Creek. Efforts to enhance the amount of coastal wetland acreage include the reconnection of mosquito impoundments and planting of red mangroveseedlings. There are an estimated 3,300 acres of impounded coastal wetlands located in the central IRL lagoon system (Steward et al., 2003). Out of that total, 2,710 acres have been reconnected to the IRL (Brockmeyer, 2005). Some of the reconnected mosquito impoundments are located atthe southern end of this planning unit, though the greater acreage of reconnected impoundments is located in the South Central IRL Planning Unit. Planting of red mangrove seedlings has been accomplished at numerous locations within the planning unit. Waters will not be placed on the Verifi ed List if the Department receives reasonable assurance that existing or proposed projects and/or 

# 109 Water Quality Assessment Report: Indian River Lagoon

# programs are expected to result in the attainment of water quality standards or consistently improve water quality over time. Appendix D contains more detailed documentation of the requirements for reasonableassurance. For this planning unit, no management plans or projects complying with the Department’s guidance for reasonable assurance have been provided for the list of impaired waters.

• South Central Indian River Lagoon Planning Unit

General Description 

# The South Central IRL Planning Unit covers about 338 square miles in South Brevard County and Indian River County. It extends from
the Sebastian Inlet and Sebastian River near Micco, south to the Indian River County/St. Lucie County line. It contains 32 waterbody segments (WBIDs). Major waterbodies in the planning unit are the IRL and the

coastal Atlantic beaches and nearshore coastal waters. Tributaries to the planning unit are the Sebastian River, C-54 Canal, Main Canal, North Canal, South Canal, and Fellsmere Canal. Drainage from the Indian River Farms Water Control District North, South, and Main Canals discharges to the IRL in this planning unit. Cities in the planning unit include

Sebastian and Vero Beach.

Water Quality Summary 

# Of the 32 waterbody segments in the South Central IRL Planning Unit, 25 segments have suffi cient data for assessment. Of these, 23 are

verifi ed impaired for at least 1 parameter assessed, 2 remain on the Planning List, and none meet standards.Data from 162 water quality monitoring stations were used for assessment of impairment. Figure 3.8 , a composite map of the planning unit, shows waters on the 1998 303(d) list, the Planning List and Verifi ed List, and potential pollution sources. Table 3.8 summarizes the water quality assessment status of all waterbody segments in the planning unit. By far the most prevalent impairment in this planning unit is mercury

in fi sh, affecting 18 of the 23 listed segments. This includes 6 segments of the IRL and 12 coastal segments. Consumption advisories have been issued for the affected segments. The second most prevalent impairment in the planning unit is DO, with 7 segments affected. Two coastal beaches, Humiston Beach and Sexton Plaza, are impaired for fecal coliforms based on beach closure advisories issued by DOH. Three other segments (North Canal, Main Canal, and South Canal) are impaired for fecal coliforms based on assessment water quality data. All waters in the South Central IRL are impaired for nutrients based on seagrass information provided by the SJRWMD (Steward and Green, 2006). Average annual loads of nutrients and TSS have shown substantial increases since 1943. Spatial differences in nutrient and TSS loads have

also been observed. The estimated 1995 annual nutrient and TSS loads in the South Central IRL were 3 to 6 times higher than in the North IRL and 6 to 15 times higher than in either Banana River or Mosquito Lagoon.

Tributaries contribute substantial loads to the IRL and have had
detrimental effects on it (Steward at al., 2003). The Sebastian River

Of the 38 permitted discharges, 12 are domestic wastewater, 3 are from concrete batch plants, and 23 are industrial wastewater. The largest industrial wastewater discharge in the planning unit is 181 mgd of cooling water from the Vero Beach Municipal Power Plant. The largest domestic wastewater discharges are from the Vero Beach Wastewater TreatmentPlant (4.5 mgd) and the Indian River County Utilities Wastewater Treatment Facilities (cumulative 6 mgd). There are two active household solid waste disposal landfi ll sites in the planning unit and the others are closed; ground water is being monitored

onsite. The Piper Aircraft active Superfund hazardous waste site is located in Vero Beach. The delineated ground water contamination site associated with Piper Aircraft is contaminated by trichloroethylene (TCE). Onsite monitoring determined that the TCE was migrating off the Piper propertyin the direction of a down gradient public supply well and posed a potential threat to private wells in the area. The site was placed on the NPL on February 16, 1990, and is being remediated to remove the TCE as part of a Consent Decree between EPA and Piper Aircraft (Department, 2005e). Figure 3.8 shows the location of these discharges in the planning unit. Appendix G lists the basin’s domestic and industrial surface discharge facilities, along with their permitted fl ows, in the planning unit. It also lists Superfund hazardous waste sites, landfi lls or solid waste facilities, and

hazardous waste sites. 4a —Impaired for one or more designated uses and the TMDL is complete;

# Nonpoint Sources: Based on land use data collected and interpreted from year 2000 aerial photography, predominant land uses in the planning unit are water and wetlands (33.4 percent) and agriculture (24 percent). Atlantic nearshore coastal waters occupy 17.8 percent of the planning unit area. Citrus accounts for 16.9 percent of the agricultural area (almost 34,000 acres) followed by improved pasture (3.5 percent) and fallowed cropland (1.2 percent). Urban and built-up areas occupy another 19 percent of the planning unit’s area, with most urban land classifi edas low and medium density residential development. Important recreational and conservation lands in the planning unit include Pelican Island National Wildlife Refuge, Sebastian Inlet State Recreational Area, and

Sebastian Buffer Preserve. Table H.5 in Appendix H contains summary and detailed information on land uses in the planning unit.Different land uses are associated with nonpoint source pollutant discharges and eroded sediments. In urban areas, stormwater discharges are managed through MS4 permits. Vero Beach is covered under Phase 2 of MS4 permitting.

Ecological Summary 

# All seven species of seagrasses that grow in the IRL are found in the South Central IRL Planning Unit south of Sebastian Inlet. Seagrasses at and near Sebastian Inlet generally are in good condition. Based on the 1991–1996 assessment data, the area of the lagoon in the vicinity of Vero Beach has some of the poorest seagrass conditions (segments IR16–20). More recent analysis of seagrass data (1998 to 2003) indicates that the condition of seagrasses near Vero Beach have improved enough to receive a good ranking (Steward, 2006). Although seagrass coverage in some segments was improved in the last decade, the seagrass depth-limit in none of these segments has reached the full restoration target. Therefore, all of the mainstem waterbody segments in the South Central IRL were assessed as being impaired for nutrients based on seagrass information. The current condition of seagrass beds in this planning unit is further

assessed and summarized in the Seagrass Assessment section of this chapter based on information provided by the SJRWMD (Steward and
Green, 2006). The lower reach of the Sebastian River has over the years acted as a sediment trap collecting muck composed of upland soils and organic matter. There are muck deposits in the Intracoastal Waterway near Vero Beach, in dredge holes, borrow pits by causeways, and other channels and turning basins. Much of the muck deposited in the IRL, about 65 percent, is located in the central part of the lagoon (Steward et al., 2003). Studies by Trefry et al. (1990) indicated that a substantial portion of the muck has been deposited over the past 40 years. Tributaries act as sediment traps and have over the years accumulated large deposits of muck. The muck at the bottom of the lagoon and its tributaries is easily resuspended, resulting in increased turbidity, reduced light penetration, increased oxygen demand,

and release of nutrients to the water column.

# Water Quality Improvement Plans and Projects 

# Numerous water quality and habitat improvement projects have been undertaken or are currently planned in this planning unit (Appendix C)

. Financial support for projects has come from the SJRWMD, Brevard County Stormwater Utility, Indian River County, local governments, and the IRLNEP. Examples of projects summarized in this section were obtained from the IRL SWIM Plan (Steward et al., 2003), Brevard CountyStormwater Utility Program (Powers, 2006), and by personal communication with Bob Day with the IRLNEP (2005). Stormwater retrofi t projects discussed cover the time period from 1995 to 2005. Agriculture, primarily citrus, is a more prevalent land use in the South Central IRL Planning Unit compared with the other planning units. BMPs were adopted in June 2002 for Indian River Citrus (Chapter 5M-2, F.A.C.) in an effort to better manage water use in groves and protect water quality. There is currently an active successful effort between the DACS, the University of Florida Institute of Food and Agricultural Sciences (IFAS), and citrus growers to implement these BMPs. IFAS has instituted a Canal Watch Program to monitor the water quality of canals receiving drainage from citrus groves in Indian River, Martin, and St. Lucie Counties and to use those data to identify and investigate locations with higher than expected loadings (http://citrusbmp.ifas.ufl .edu/indianriver/canalWatch
.html). Discharges from the Indian River Farms Water Control District, delivered through North, Main, and South Canals, impact about 12 milesof the southern part of the IRL. Water quality and the condition of seagrasses in the area have historically been poor compared to other segments of the lagoon. Starting in 2001, responsible agencies including Indian River County, SJRWMD, Indian River Farms Water Control District, Vero Beach, and the Indian River County IFAS Extension Offi ce organized to develop a water management plan. Other agencies may be asked to partner

in the effort in the future. The fi nal plan will need to balance restoration needs of the IRL lagoon system and drainage needs. The Indian Farms Drainage District Signage Project is an Indian River County project directed at increasing public awareness of the connection of the Indian River Farms Canals to the IRL lagoon system. Educational signage will be placed throughout the Indian Farms Drainage District in an effort to discourage the dumping of debris into Drainage District canals. The Sebastian River watershed covers approximately 172 square miles and contributes greater loadings of nutrients and suspended solids to the IRL lagoon system than either Crane Creek or Turkey Creek. Several water resource planning efforts and water quality improvement projects are under way or proposed for this watershed. The implementation of plans and projects is anticipated to lead to improved fl ood control, improved salinity maintenance, and reductions in nutrient and suspended solids loads. Individual plans and projects are specifi c to geographic area and sponsoring entity. The fi nal goal of all planning efforts is to meet salinity and PLRG targets for the Sebastian River and the IRL lagoon system. Summaries 

# 117 Water Quality Assessment Report: Indian River Lagoon

# of major water quality improvement projects and planning efforts in the planning unit are as follows:

• The lower reach of the Sebastian River is a sediment trap accumulating a thick deposit of muck. The dredging proect is currently underway and will continue through November of 2008, the start of manatee migration. The fi nal season of dredging will begin again in April of 2009.

• Hydrologic restoration of the Herndon Swamp is proposed.

Herndon Swamp is located in the Sebastian Buffer Preserve and is the historical headwater of the North Prong of the Sebastian River (SJRWMD, 2006a).

• The city of Sebastian has prepared a surface water master plan that

addresses pollutant reduction and fl ood control. Completed parts of the plan included the improvement of a water control structure on the Elkam Canal and a stormwater treatment pond that treats the Stonecrop area drainage.

• SJRWMD is assisting the city of Sebastian with the design and

construction of the Sebastian Stormwater Park in the southern part of the city, which will treat runoff from a 1,300 acre residential area
(Steward et al., 2003). Recreational facilities will be included in the park. Sebastian will assume operation and maintenance of the park facility.

• Within the North Prong Sebastian River drainage, 496 acres of land

located near the Sottile Canal were purchased by the SJRWMD. A large portion of that acreage has been set aside for a stormwaterdetention area to treat runoff from projected build-out of the Barefoot Bay Community and for dredge spoil disposal from future dredging of the Sebastian River.

• Water resource planning is in progress between SJRWMD, U.S.

Army Corps of Engineers, Sebastian River Water Control District, and Fellsmere Water Control District. These planning efforts are expected to result in improved stormwater management, salinity control, water level management, and erosion control.

• Indian River County has completed a stormwater improvement

project at Vero Lake Estates. The Vero Lake Estates project involved a redesign of upland treatment ponds into a wet detention system including improvements to swales. The project treats 3,871 acres of residential development and reduces loadings to the South Prong of Sebastian River and ultimately the IRL lagoon system.

Additional stormwater improvement projects initiated by local governments will contribute to direct reductions in nutrient and sediment loads to the IRL lagoon system. In an effort to reduce sediments, Indian River County is paving dirt roads and constructing swales to control sediments in road runoff that currently discharges directly into the IRL lagoon system. 

# 118 Water Quality Assessment Report: Indian River Lagoon

# The cities of Vero Beach and Sebastian have installed baffl e boxes to reduce

sediment loads. The baffl e box installed in Sebastian treats runoff from Main Street in the older downtown part of the city. Sebastian has plans to

add another baffl e box on Indian River Drive. This newer baffl e box will be designed to remove nutrients in addition to sediment from a 96-acre drainage area. The city of Fellsmere has developed a Master Drainage Plan, paved State Street, and constructed a retention pond to serve the project area. Indian River County has initiated the Gifford and Roseland community drainage improvement projects to address storm water runoff from mixed residential and commercial development. Gifford is located north of Vero Beach and Roseland is just south of the Sebastian River. The Gifford improvement project requires construction of a 4.5-acre detention lake and swale. The Roseland element of the project will construct a wet detention pond to treat stormwater runoff before discharge into CollierCreek. Brevard County’s Stormwater Utility Program constructed stormwater detention ponds on Church Street and Fleming Road near Micco for

treatment of stormwater runoff and for control of fl ooding and installed

exfi ltration piping and sediment traps along Main Street in Micco.

Habitat restoration and invasive plant management activities are proposed for Nelson’s Island, Wabasso Causeway Park, and Pelican Island.

Shoreline stabilization reduces the amount of sediment that can enter theIRL lagoon system. The Coastal Resources Group has primary responsibility for removing exotic vegetation and planting cord grass along the shoreline of Nelson’s Island. The U.S. Fish and Wildlife Service is taking

the lead in the restoration and stabilization of Pelican Island. Indian River County has planted native vegetation and constructed coquina revetments to reduce erosion and stabilize the shoreline at the Wabasso Causeway Park. Efforts to enhance the amount of coastal wetland acreage include the reconnection of mosquito impoundments, public acquisition of wetlands, and planting of red mangrove seedlings. There are an estimated 3,300 acres of impounded coastal wetlands located in the central IRL lagoon system (Steward et al., 2003). Out of that total, 2,710 acres have beenreconnected to the IRL (Brockmeyer, 2005). Most of the acreage of reconnected impoundments is located in the South Central IRL Planning Unit.More than 4,000 acres of wetlands and their adjacent uplands in the southern part of the North Central IRL Planning Unit and the South Central IRL Planning Unit are identifi ed for purchase by the Blueway Program(Steward et al., 2003). Planting of red mangrove seedlings has been accomplished at numerous locations within the planning unit. Waters will not be placed on the Verifi ed List if the Department receives reasonable assurance that existing or proposed projects and/or programs are expected to result in the attainment of water quality standards or consistently improve water quality over time. Appendix D contains more detailed documentation of the requirements for reasonable assurance. For this planning unit, no management plans or projects complying with the Department’s guidance for reasonable assurance have been provided for the list of impaired waters.

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

This chapter evaluates the potential infl uences of ground water and natural geologic, soil, and/or ground water chemistry on surface water quality in the Indian River Lagoon (IRL) 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 (IWR) listing thresholds due to natural conditions. The listing parameters receiving scrutiny include nutrients (chlorophyll a ), dissolved oxygen (DO), and iron. The available ground water data used for this assessment are limited by both the number of observations and the period of record (generally 1989–2003).



# Geology, Soil, and Ground Water

Setting The hydrogeology of the basin is very heterogeneous. Three main

aq uifers—the Floridan, intermediate, and surfi cial aquifers—underlie

the IRL Basin. The surfi cial aquifer is composed of interbedded lenses of
marine, fi ne to medium sand, shell, and silty clay of Pliocene and Upper Miocene ages that lie on top of a confi ning layer, consisting of clay and other less-permeable material of the Hawthorn Group. The thickness

of the surfi cial aquifer generally increases toward the coast and is about 100 feet but can be as much as 400 feet in portions of the basin.

The confi ning unit separates the surfi cial and underlying Floridanaquifer systems and in parts of the basin can also include the intermediate aquifer system. The intermediate aquifer consists of more-permeable lenses of sand, shell, and limestone that occur within the Hawthorn Group

confi ning layer, which is thinner or absent in the northern portions of the basin. In these northern areas, this allows a greater exchange of ground

water between the Floridan and surfi cial aquifers and the IRL (Toth, 1987). In the central portion of the basin, the Floridan aquifer is completely

confi ned by the Hawthorn Group material, which is approximately 100 feet thick. The upper Floridan aquifer is composed of the Ocala Limestone and in some parts, the Avon Formation. The Ocala Limestone has high permeabilities that are increased along bedding planes and by fractures

and conduits.

Ground water fl ow in the Floridan aquifer is generally west to east toward the Atlantic Ocean. The potentiometric surface of the Floridan aquifer ranges from 0 to 35 feet above mean sea level along the coastline. 

# 121 Water Quality Assessment Report: Indian River Lagoon

# The water table of the surfi cial aquifer system is shallow, and its gradient roughly approximates the land surface topography (Healy, 1982). The water table usually is deeper in Martin County (8 to 10 feet below the land surface) (Healy, 1982). There is also a vertical exchange of ground water between aquifers, and most of the basin is a ground water discharge area for the Floridan aquifer. Significant variations in ground water levels occur seasonally, and a longterm decrease in the potentiometric surface is largely attributed to increased ground water withdrawals. The potentiometric surface elevations are above sea level for the entire length of the IRL. This, combined with the general

lack of a confi ning unit in some areas, also makes much of the IRL a potential zone of submarine ground water discharge. The soils in the basin—predominantly Entisols, marsh Spodosols, and poorly drained coastal Alfi sols and Spodosols—are among the most preferred soils for citrus. They are composed of sandy materials with low organic content (Obreza and Collins, 2002). Some of these soils have a chemical mechanism to bind phosphorus due to a differing amount of silt and clay. Other soils dominated by quartz sand lack appreciable amounts of these silts and clays, but in many cases the sand is coated with iron and/or aluminum, which also have some capacity to sorb phosphorus.

Ground Water–Surface Water Interactions The interaction between ground water and surface water is signifi

-

c ant in the IRL Basin. Natural streams are supported by ground water discharge. Baseflow separation analyses performed by the Florida Department of Environmental Protection (Department) for 9 streams across the basin showed ground water contributions of between 54 and 71 percent of

the total fl ow (Tinsley, Li, and Gao, 2007). Canals intersect the surfi cial aquifer and drain large areas to artifi cially suppress the water table and make more land available for agricultural and urban development. Water in major canals is manipulated to provide aquifer recharge and prevent

saltwater intrusion near the coast. In other near-coastal areas and in the vicinity of canals that do not have salinity control structures, saltwater

intrusion into the surfi cial aquifer occurs. The basin includes areas of artesian ground water flow from the Floridan aquifer. The amounts of upward fl ux through seepage, springs, sinks, or unplugged wells to the surfi cial and intermediate aquifers and to surface waters (including points offshore beneath the Atlantic Ocean) depend on the thickness and the extent of breaching of the overlying confi ning layer.Thus surface water in the basin could consist of a mixture of direct precipitation, surface runoff, seepage from the surfi cial aquifer, and discharge from the Floridan aquifer. Ground water seepage into streams in the basin is appreciable. The direct submarine discharge of ground water to the IRL itself may be signifi cant. Studies have shown that the submarine discharge of water can transport nutrients from agricultural lands (Simmons, 1992; Gallagher, Dietrich, Reay, Hayes, and Simmons, 1996) and residential septic tanks (Weiskel and Howes, 1992) to coastal marine waters. Hydrogeological studies by the U.S. Geological Survey (USGS) have indicated that in the 

# 122 Water Quality Assessment Report: Indian River Lagoon

# Upper IRL, only 1 to 5 percent of interstitial water is composed of meteoric ground water. The remaining 95 to 99 percent is probably recycled lagoon seawater. Nutrient concentrations were 3 to 5 times higher in the seepagewater than the lagoon water, suggesting that submarine ground water discharge could be a critical component of the coastal nutrient budget.

Overview of Ground Water Quality Ground water quality statistics are presented in T able 4.1 for the

surfi cial aquifer and Table 4.2 for the Floridan aquifer in each planning unit. The data were obtained from the Department’s Oracle-based Ground Water Information System (OGWIS) database. Data retrieved from

OGWIS were for the surfi cial and Floridan aquifer systems. Evaluatingground water data in each planning unit with listed surface waters, comparing this information with data on surface waters on the draft Verifi ed List, and analyzing other planning-unit-specifi c characteristics may help to identify more instances where naturally occurring conditions infl uence surface water quality.

# Nutrients In a recent pollutant load reduction goal analysis for the IRL, the

S t. Johns River Water Management District (SJRWMD) recognized that the actual load currently contributed by direct wastewater discharge from permitted facilities is, in most cases, a small fraction of the total annual external load of nutrients to the lagoon (on the order of 2 percent). Thebulk of the nutrient load into the system must therefore come from nonpoint sources. The pollutants responsible for excessive chlorophyll agrowth, measured as high chlorophyll a levels in streams and estuaries and high Trophic State Index values in lakes, are nitrogen and phosphorus. Both of these nutrients exist naturally in the environment, but both can be released by anthropogenic activities. Both nitrogen and phosphorus exhibit spatial and temporal variability in the IRL Basin. Generally, the basin is mainly a phosphorus-limited system, with some colimitation based on total nitrogen (TN)/total phosphorus (TP) ratios in the North IRL Planning Unit. Nitrogen in water is derived from a variety of sources, some natural and others due to human activities. Typical anthropogenic sources of nitrogen include atmospheric deposition, agricultural and residential
fertilizers, and domestic wastewater. Based on available data, nitrate and Table 4.2: Ground Water Statistics for Planning Units in the Indian River Lagoon Basin, Floridan Aquifer

# 124 Water Quality Assessment Report: Indian River Lagoon

# nitrate+nitrite (both reported as “nitrate”) levels in the surfi cial aquifer are not particularly elevated in the northern portions of the basin, but are elevated in wells located in the central and southern portions of the basin. In contrast, the highest levels of ammonia, ammonia+organic nitrogen, and phosphorus in the surfi cial aquifer are found in the northern portion of the basin. Signifi cant concentrations of ammonia and organic nitrogen were observed in shallow ground water and surface waters in the basin. Figure 4.1 shows the distribution of ammonia in the surfi cial aquifer in ambient monitoring wells. Total Kjehldahl nitrogen (TKN) is the combination of organically bound nitrogen and ammonia, which are most commonly found at highlevels in untreated wastewater and are frequently monitored as an indicator of industrial pollution and sewage. Low to moderate levels of ammonia and organic nitrogen occur naturally in the environment, and lake and stream medians for TKN in Florida are typically higher than 1 milligram per liter (mg/L) (Department, 2004). The highest levels of ammonia and ammonia+organic nitrogen in shallow ground water in the basin were in the Banana River Planning Unit, but ground water concentrations in all planning units except Mosquito Lagoon were elevated compared with those for the SJRWMD as a whole. The by-planning-unit discussions evaluate

these conditions in more detail. In an interagency study using data from 1979 to 2004, the seasonality of surface water constituents was researched for the IRL (Qian, Migliaccio, Wan, Li, and Chin, 2007). Major water quality indicators (conductivity, turbidity, color, and chloride) exhibited signifi cant seasonal patterns.

Almost all nutrient species that included nitrate, ammonia, and phosphorus had identical seasonal patterns of concentrations that were signifi cantly greater in the wet than in the dry season (nitrate, ammonia, TKN, phosphate, and total phosphorus). The study fi ndings indicate that nutrient delivery to surface waters via wet deposition, runoff, or ground water seepage corresponds with rainfall and the associated fl ushing of nutrients. The seasonality of nutrient delivery could be related to the application of fertilizers for citrus groves and to some extent atmospheric deposition and

reactions with rainwater. Citrus farming is a signifi cant land use in this basin and is a potentially signifi cant source of nutrients to ground and surface waters. The Florida Agricultural Statistics Service reported in 1996 that about 35 percent of Florida’s irrigated citrus acreage was in Indian River, Martin, and St. Lucie Counties. A USGS study by Crandall (2000) estimated that approximately 175 to 225 pounds per acre of nitrogen (generally as ammonium nitrate or potassium nitrate) are applied annually to groves. Each year about one-third of the total annual nitrogen fertilizer is applied in the fall, with the remaining two-thirds applied before June (Tucker, Alva, Jackson, and Wheaton, 1995) using either dry or a combination of both liquid and dry fertilizer. The by-planning-unit discussions evaluate these conditions. Phosphorus found in ground water and surface water in the basin
can be from natural sources, natural historical accumulation, more recentanthropogenic sources, or a combination of sources. Land use in the vicinity may dictate the extent to which these accumulations are characterized

# as naturally occurring. In agricultural areas, fertilizer applications and livestock waste can discharge phosphorus to surface waters via runoff. The use of phosphorus-containing fertilizers has been documented for citrus farming, which is the predominant agricultural land use in the basin. The capacity of the soils in citrus farming areas to adsorb phosphorus varies depending on clay and organic content and the coating on soil grains. Insome areas, phosphorus runoff is more of an issue due to soil characteristics. Also, activities that drain or disturb phosphorus-containing peat and

muck—such as canal construction or the fl ooding of agricultural fi elds— may release phosphorus into surface water.Orthophosphate, which is the soluble, inorganic form of phosphorus most typical of ground water, can be derived from natural geologic material, mineralized and released from peat and muck, or leached from inorganic fertilizers. Orthophosphate is slightly elevated in the Floridan aquifer, while orthophosphate and phosphorus concentrations are much higher in the surfi cial aquifer compared with the Floridan aquifer. Figure 4.2 shows the distribution of orthophosphate in ground water samples from the surfi cial aquifer in ambient monitoring network wells. Nitrate and phosphate levels in the counties to the west, representing upgradient ground water, are similar to those in the IRL Basin. Phosphorus and iron have an affi nity for one another, which may explain the coincidence of elevated orthophosphate and iron in the surfi cial aquifer sampling locations ( Figures 4.2 and 4.3 ). In estuarine systems, research indicates that phosphorus adsorbs to sediments enriched with iron

under aerobic conditions and can be released on burial under anaerobic conditions (Pant and Reddy, 2001). Peat and organic muck are also associated with phosphorus retention and are found in the interior marshy areas of the basin that have accreted during fl ooded conditions and in stream and lake beds. The organic material can be oxidized during dry periods or when wet areas are drained. This can result in decreased net phosphorus retention and the conversion of organic phosphorus into the more mobile inorganic form, which can be subsequently released into the water column (Olila and Reddy, 1997; Pant and Reddy, 2001). The fl ooding of soils in previously farmed areas hasbeen known to release phosphorus to the water column from residual fertilizer phosphorus adsorbed to the soil (D’Angelo and Reddy, 1994; White, Reddy, and Moustafa, 2004). The results of a study in the Lower St. Johns Estuary (Malecki, White, and Reddy, 2004) indicate that the internal fl ux of dissolved reactive phosphorus (as well as ammonium) from sediments may be a signifi cant portion of the total load of these constituents being

released to surface waters.

Iron Iron is the metal most typically identifi ed with a natural source, and

elevated iron concentrations are common in the surficial aquifer throughout the state. Generally, iron is found in abundance in organic soils, but it can also form as a coating on quartz grains in low organic soils such as those in the IRL Basin. Human activities such as mining, soil erosion from construction and agricultural sites, the application of iron-containing

# fertilizer, and the landfilling of wastes may also cause elevated iron concentrations in ambient waters on a local scale. However, elevated iron on a broad, regional scale is due to natural conditions. In an evaluation of enrichment of iron in surface waters of the basin, Tinsley et al. (2007)

found that excessive levels of iron in four waterbodies in the basin were naturally occurring. Elevated concentrations of iron in solution in natural water frequently occur along with low pH, low oxidation-reduction potential, and high dissolved organic carbon content. The low DO concentrations in ground water provide the anoxic setting where iron is in its most mobile form. Iron

concentrations in the surfi cial aquifer are much higher than in the Floridan aquifer by orders of magnitude due to these conditions. The elevated iron

in the surfi cial aquifer could come from the iron-coated grains in soils and also from clays in the underlying material of the Hawthorn Group. Upwelling ground water could also possibly transport the soluble iron from

the Hawthorn to the surfi cial aquifer. The ground water coming fromanoxic conditions in the aquifers can then interact with surface waterbodies, where the iron can concentrate in organic sediments.

Median concentrations of iron in the surfi cial aquifer wells are elevated in all of the basin’s planning units that have data (Table 4.1)

, suggesting that where ground water to surface water pathways exist, elevated iron in ground water is also a source of elevated iron in surface waterbodies. Figure 4.3 shows the common occurrence of elevated iron concentrations in the basin’s ambient monitoring wells in the surfi cial aquifer.

Dissolved OxygenDO levels can be depressed in surface water systems because of nutrien t enrichment and/or biochemical oxygen demand (BOD). The nutrient enrichment in shallow ground water in the form of ammonia and organic nitrogen and phosphorus was discussed earlier. Low DO can also be attributed to poor water circulation caused by stream channelization or disruption in fl ows. In addition, ground water infl ows, where signifi cant, can lower DO levels in surface water systems. DO levels in ground water are always naturally low, and thus low DO is a natural condition in ground water in all of the basin’s planning units ( Tables 4.1 and 4.2 ). Also, ammonia and organic nitrogen and phosphorus in ground water discharges could contribute to nutrient loads in some surface waters. Orthophosphate and phosphorus medians in the surfi cial aquifer are elevated in all planningunits, and phosphorus, ammonia, and organic nitrogen are particularly elevated in the surfi cial aquifer of the Banana River Planning Unit ( Tables 4.1

and 4.2 ; Figures 4.1 and 4.2 ).

Coliform Bacteria

Coliform levels can be diffi cult to evaluate in ground water samples
from wells, since biofi lms can form and grow inside the well casing so that populations found in wells do not necessarily refl ect those in the aquifer. Coliform in wells was evaluated because waterbodies in three planning units are impaired for coliform and/or were the cause of beach closures. Based on the available data, wells with ground water coming from either 

# 130 Water Quality Assessment Report: Indian River Lagoon

# the surficial or Floridan aquifers were not found to have coliform contamination during the period from 2000–06. These data do not suggest a signifi cant relationship between bacteria in wells and surface waters.



# Evaluations by Planning Unit

This section summarizes, for each planning unit, ground water chemical characteristics that may be related to waterbodies on the draft Verifi edList, evaluates ground water fl ow, reviews pertinent geologic and soil information, and evaluates land use and anthropogenic sources.

Banana River Planning Unit Three estuarine waterbodies are listed as impaired because of low DO
( waterbody identifi cation numbers [WBIDs] 3044A, 3057B, and 3057C).WBID 3044A is a harbor in the Banana River, and WBID 3057C is a segment of the Banana River. TN was identifi ed as the causative pollutant for low DO in all three estuarine waterbodies, with median nitrogen values of 1.5, 1.5, and 1.6 mg/L, respectively, exceeding the IWR threshold. In the

surficial aquifer, median ammonia and ammonia+organic nitrogen concentrations were 1.7 and 0.65 mg/L, respectively, which were the highest values for all planning units in the basin. In addition, orthophosphate and phosphorus were highest in the planning unit’s surficial aquifer, with medians of 0.82 and 0.72 mg/L, respectively. It is possible that the nutrients in ground water and these surface waters have sources in common and that ground water discharge provides a nutrient load to these waters. Ground water discharge to the estuary could be signifi cant. The USGS found that the rates of ground water seepage to the IRL were spatially and temporally heterogeneous, ranging from 3 to 100 milliliters per meter square per minute (mL m -2 

# min -1 

# ) during May (the dry season)

to 22 to 144 mL m -2 

# min -1 

# during August (the rainy season). These data implied that the rainfall increased the seepage rates. The study noted that the wide range in rates is also likely caused by variation in sediment permeability and other geologic characteristics (Swarzenski, Martin, and
Cable, 2007).

Mosquito Lagoon Planning Unit The planning unit does not currently contain any waterbodies that

a re listed as impaired. Data from the surfi cial aquifer indicate that ground water quality in the planning unit is similar to the North IRL Planning
Unit, which is discussed below.

North Indian River Lagoon Planning Unit Three waterbody segments in the planning unit are listed for DO
( WBIDs 2963D, 2963F, and 3028); all are classifi ed as estuaries. In addition, two segments, Indian River above NASA Causeway (WBID
2963E) and Indian River above Brewer (WBID 2963F), are listed for nutrients (chlorophyll a ). All these segments are classifi ed as estuaries of the Indian River, except for Addison Creek (WBID 3028), which is a

freshwater stream. 

# 131 Water Quality Assessment Report: Indian River Lagoon

# TN was identifi ed as the causative pollutant for low DO in the three segments (WBIDs 2963D, 2963F, and 3028), with median nitrogen values of 1.4, 1.3, and 1.6 mg/L, respectively. The surfi cial aquifer in the planning unit could contribute to low DO in some waterbodies. Stream

basefl ow data obtained in the area suggest that ground water contributes approximately half of the total stream fl ow (Tinsley et al., 2007). Ground water exists as a potential source of nutrients to surface waters.Ammonia and ammonia+organic nitrogen levels are lower than the statewide medians for streams, but phosphorus is several times higher in shallow ground water than it is in surface waters of the planning unit.

North Central Indian River Lagoon Planning Unit Four estuarine segments in the planning unit (WBIDs 2963B, 3082, 3085A, and 3098) are impaired by low DO. The Eau Gallie River (WBID 3082) receives drainage from the northern part of the city of

Melbourne and then fl ows into the northern segment of the Indian River (WBID 2963B). Turkey Creek (WBID 3098) is the subject of numerous plans for restoration that include muck dredging and the rediversion of waters with canals. Crane Creek (WBID 3085A) causative pollutant for

low DO was identifi ed as BOD, with a median value of 2.6 mg/L.

TN was identified as the causative pollutant for low DO in three estuarine waterways (WBIDs 2963B, 3082, and 3098), with median nitrogen values of greater than 1 mg/L for each of them. The surfi cial aquifer in the planning unit has a DO median of 1.0 mg/L, and so ground water discharge alone could suppress DO if discharge is signifi cant and mixing is minimal, such as in a deep stream channel or canal. Ground water is a potential contributing source of nutrients to surface waters. Ammonia and ammonia+organic nitrogen levels in the planning unit are lower than the typical statewide medians for streams, but phosphorus is several times higher in shallow ground water than it is in surface waters of the planning unit. Basefl ow for the Eau Gallie River was 63 percent ( Tinsley et al., 2007); thus, if other listed streams are comparable, the ground water contribution of nutrients could be a factor in the DO listing.The Department and SJRWMD designed a ground water Very Intensive Study Area (VISA) near the town of Palm Bay to evaluate the effects of suburban development, particularly septic tanks and canals, on water quality in the surfi cial aquifer. The SJRWMD installed 30 monitoring wells in the late 1980s and sampled them on several occasions during the 1990s. Many of the wells were installed between homes and canals or near Turkey Creek to intercept ground water fl ow from the neighborhoods to the surface waterbodies. Since then, many homes in the VISA have been hooked up to the municipal sewer system. It appears from reviewing theresults of this VISA that sewering of the new communities may be preventing environmental degradation of the surfi cial aquifer system and therefore helping to maintain the environmental health of the watershed. 

# 132 Water Quality Assessment Report: Indian River Lagoon

# South Central Indian River Lagoon Planning Unit The planning unit includes the southern part of the IRL. Submarine

g round water discharge is believed to occur in this area and can control the salinity of the lagoon water. Several waterbodies in the planning unit are listed as impaired because of low DO (WBIDs 3128, 3129A, 3129B, 3135, 3147, 3153, and 3158). In addition, the North Prong Sebastian River (WBID 3128) is listed as impaired by iron.

The surfi cial aquifer in the planning unit has a DO median of 0.6 mg/L, which is less than typical for the surfi cial aquifer in the basin and the SJRWMD. There is a high variation in surface water DO levels, suggesting potential ground water discharge under certain conditions and in specifi c locations. The North Canal (WBID 3147) also had phosphorus listed as an additional causative pollutant for low DO. The median phosphorus level was 0.25 mg/L in the surfi cial aquifer in the planning unit. This level is much higher than the phosphorus in surface waters, and so phosphoruscontributions by ground water should be a consideration. Estimated basefl ow to the North Prong of the Sebastian River is 66 percent (Tinsley et al., 2007); thus, ground water discharge should be considered as an input to

these waters. While the North Prong Sebastian River (WBID 3128) was listed for iron, naturally elevated iron is characteristic of the area. Highly organic

muck soils occur in the fl oodplains and margins of waterbodies, water pH is slightly acidic, and color is high—conditions that frequently point toward naturally elevated iron in surface water. Shallow ground water in the vicinity is also high in iron. The median iron concentration for the

surfi cial aquifer in the South Central IRL Planning Unit is greater than 1,000 mg/L. Elevated iron concentrations in surface water and ground water are both related to the organic material that adsorbs, concentrates,

and releases iron. The release of iron to surface waters could also result from the erosion of iron-containing soil from ditch banks and other

disturbed areas. A statistical analysis was conducted to identify the infl uences from humic materials and pH on the iron concentrations found in the North Prong Sebastian River (Tinsley et al., 2007). Human-induced erosion of sediments and other activities in the intensively managed citrus area drained by the North Prong Sebastian River could also cause iron to be

elevated in the river.



# Recommendations

As is the case elsewhere in the state, ground water seepage provides
water to the streams, canals, and coastal waterbodies of the basin and can

infl uence surface water quality. Phosphorus, nitrogen, and iron are elevated

in the surfi cial aquifer and could affect surface water quality to varyingextents in the basin via ground water infl ows. The following recommendations apply to ground water as a contributing factor to surface waters listed as impaired in the IRL Basin: 

# 133 Water Quality Assessment Report: Indian River Lagoon

# • Natural sources of phosphorus are present and ground water-related phosphorus inputs should be considered in total maximum daily loads (TMDLs) developed for DO-listed surface waters in the basin. In some instances, ground water may also be a source of nitrogen.

• Both surface and ground waters of the IRL Basin are enriched in

iron. Natural sources of iron are the major cause of impairment in the waterbodies listed for iron, and ground water-delivered iron is signifi cant. TMDLs should not be developed for surface waters in

the basin that are listed for iron unless direct evidence of an anthropogenic source is provided.

• Ground water contributions of low DO may be further evaluated for

waterbodies that have been listed as potentially impaired because of

low DO but have no identifi ed causative pollutant. 

# 134 Water Quality Assessment Report: Indian River Lagoon

# Chapter 5: The Verified List of Impaired Waters

Public Participation

The Florida Department of Environmental Protection (Department) worked with a variety of stakeholders to develop and adopt Verifi ed Lists of impairments for waters in the six Group 5 basins across the state. The waters included on the lists met the listing requirements of the Impaired
Surface Waters Rule (IWR).

Drafts of the Verifi ed Lists were made available for public review and comment on the Department’s Total Maximum Daily Load (TMDL) Program Web site, at http://www.dep.state.fl .us/water/tmdl, and they were sent on request to interested parties by postal mail and e-mail. Numerous public meetings were held in each basin to encourage public participation in the listing process (Table 5.1). Citizens were given opportunities to comment on the draft lists in person, at the public meetings, and in writing. Lists that were revised based on received public comments were also made available for further public review and comment throughout the full comment period. Final basin-specifi c Verified Lists, developed 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 E 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 D provides additional information. In the IRL Basin, no management plans or projects complying with the Department’s guidance for reasonable assurance have been provided for the Verifi ed List of impaired waters.



# The Verified List of Impaired Waters

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 originally low. In the case of mercury in fish, the priority remains low. Where a parameter was only identified as impaired under the IWR, priorities of high, medium, or low were used.

# Pollutants Causing Impairments

Table 5.4 su mmarizes the major parameters for which verified impairments were identifi ed.

Table 5.4 shows that the greatest number of verifi ed impairments in the IRL Basin are for mercury in fi sh. Fish consumption advisories for mercury have been issued for all of Florida’s coastal marine waters in all basins, including the IRL Basin. To address this problem, one TMDL for mercury in fi sh will be developed for the entire state by 2011. Dissolved oxygen (DO) and nutrients are the next most prevalent impairments in the basin (19 and 14 listings, respectively). DO levels are

often influenced by nutrient levels in surface waters; therefore, DO impairments might be addressed by addressing nutrient impairments in the basin. Interim pollutant load reduction goals have been developed for nitrogen,phosphorus, and total suspended solids for the IRL lagoon system. Legislation in 1990 removed all domestic wastewater discharges from the lagoon and with the inception of the Indian River Lagoon National Estuary Program, numerous stormwater projects have been undertaken in the basin to remove nutrient and sediment loads from the lagoon system.DO levels, however, are not always associated with a causative pollutant, and low DO levels might be a naturally occurring condition in some waters. Where DO does not meet state standards, and the DO impairment

has been identifi ed as a naturally occurring condition, TMDLs will not be developed. Metals impairments in the basin (other than mercury in fi sh) (four listings) are believed to be associated with surface water/ground water

# interaction in the basin (iron), antifouling paints (copper), and fuels
(nickel). Beach closures (two listings) and fecal coliforms (seven listings) are related to bacterial contamination. While not a large problem in the IRL Basin, these impairments must be addressed through TMDLs. Of the 93 waterbody segments in the IRL Basin, 68 waters are impaired for at least 1 parameter. There are a total of 109 parameter listings for impairment following the methodology in Appendix E . The South Central IRL Planning Unit has the largest number of impaired parameter listings with 23, followed by the Banana River Planning Unit with 14 listings.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 DO exceedances. 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 (BOD), 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 were a suffi cient number of DO exceedances to place the water on

the Verifi ed List. Where a water has a suffi cient number of exceedances for placement on the Verifi ed List but the median values are less than the screening levels, the DO impairment for that segment is considered a potential impairment and it is retained 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.

Table 5.7 displays the nitrogen and phosphorus ratios for stream and lake segments potentially impaired by nutrients.

Listing Based on Other Information Indicating Nutrient Im balance The following waterbodies were listed as impaired based on “other

i nformation” indicating an imbalance in fl ora or fauna, pursuant to Rule 62-303.450(2), F.A.C. Based on information provided by the St. Johns River Water Management District, the distribution of seagrass in the waterbody identifi cation number (WBID) has decreased due to elevated

nutrients.

# 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 causingthe 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 Verifi ed 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 to identify 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. 

# 158 Water Quality Assessment Report: Indian River Lagoon

# 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 fi sh consumption advisories for mercury (due to the current insuffi cient understanding of how mercury cycles in the environment); 

# 159 Water Quality Assessment Report: Indian River Lagoon

# • Canals, urban drainage ditches, and other artifi cial waterbody segments that are listed only due to exceedances of dissolved oxygen

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 priority waters for TMDL development in the Indian River Lagoon (IRL) Basin. There are 21 waters listed in the table that are high priorities on the 1998 303(d) list.



# Total Maximum Daily Load Development

TMDLs for point and nonpoint source pollutants will be developed for impaired waterbodies during Phase 3 of the Watershed Management Cycle, and the TMDLs will be adopted by rule at the end of the phase. TMDL development involves determining the maximum amount of a given pollutant a waterbody can assimilate and still meet the applicable numeric or narrative state water quality criterion for the pollutant.

# cases, this “assimilative” capacity will be determined using computer modeling (both hydrodynamic and water quality models) that predicts the fateand transport of pollutants in the receiving waters. Modeling for the typical TMDL will include model setup, calibration, and verifi cation, 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 (worst-case temperature and ambient fl ow conditions, and an assumption that all permitted point sources discharge at the maximum permitted quantity). 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 commonly listed 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 water flow. 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. 

# 177 Water Quality Assessment Report: Indian River Lagoon

# 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 regulatory programs will require cooperation from dischargers to implement best management practices (BMPs) voluntarily. While a detailed allocation will ultimately be necessary to implementa 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 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 IRL 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; 

# 178 Water Quality Assessment Report: Indian River Lagoon

# • 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, applicable
local 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 Sur face 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 water 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)

# 190 Water Quality Assessment Report: Indian River Lagoon



# 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 Florida Legislature by February 2001 addressing the allocation

process.

# Water Quality Assessment Report: Indian River Lagoon 

# 191

• 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 (FDACS), the Soil and Water Conservation Dist ricts, 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 FDACS to develop interim measures and BMPs to address nonpoint sources. While BMPs would be adopt ed 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 Florida 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

.

# 192 Water Quality Assessment Report: Indian River Lagoon



# 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 reduce the amount of pollutants that cause impairments must also be produced and implemented.

# Water Quality Assessment Report: Indian River Lagoon 

# 193

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.

# 194 Water Quality Assessment Report: Indian River Lagoon



# 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.

# 195

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

# 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.”

# 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.

# 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 (SJRWMD) recently adopted basin-specific criteria for the Lake Apopka watershed that require the phosphorus loading from new development not to exceed pr edevelopment phosphorus loading.

# 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 Program in lo cal landscaping codes. (See Noteworthy for a definition of riparian).

# Typically, BMPs refer to a practice or co mbination of practices that, based on sound science and best professional judgment, are determined to be the most effective and practicable means of reduci ng nonpoint source pollutant di scharges and improving water quality. Both economic and technological cons iderations are included in the evaluation of what is practicable. BMPs may include stru ctural controls (such as retention areas or detention ponds) or nonstr uctural controls (such as street sweeping or public education). Many BMPs have been developed for urban st ormwater to reduce pollutant loadings and peak flows. These BMPs accommodate site-specific conditions, including soil type, slope, depth to ground water, and th e designation of receiving waters.

NOTEWORTHY: DEFINITION OF RIPARIAN



# Riparian: Of, on, or relating to the banks of a natural course of water.

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 Florida Legislature authorized the use of Interim Measures (IMs) 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. Once FDACS 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.

# S TRATEGIES


# 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 trading. The Department will assemble a Technical Advisory Committee to help devel op a pollutant-trading ru le, which must be reviewed by the Florida Legislature prior to its adoption. The Department will also

continue to work with local stakeholders on TMDL allocation issues and implementation plans.

# Appendix D: 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:

1. 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

2. 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 U.S. Environmental Protection Agency (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 Florida Department of Envir onmental Protection's (Department) decision, rather than attempting to establish spec ific 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.

# Water Quality Assessment Report: Indian River Lagoon 

# 221

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 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).

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

as follows:

Section 62-303.600, Evaluation of Pollution Control Mechanisms



# 1. 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.

2. 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 the EP A, 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

# 222 Water Quality Assessment Report: Indian River Lagoon



# 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.



# 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 that the pollution control programs under consideration be “under local, stat e, or federal authority.” A pollution control program will be considered "under loca l, state, or federal authority" if the program is subject to or re quired by a local ordinance, state statute or rule, or federal statute 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 action s to assure the 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.

# 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.

# Water Quality Assessment Report: Indian River Lagoon 

# 223

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.



# 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:

1. 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 NED identifier (w hen 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.

2. A Description of the Water Qua lity or Aquatic Ecological Goals —a description of the water qua lity–based targets or aqua tic ecological goals (both interim and final) that have been established for the pollutant(s) of concern, the averaging period for any numeric water qu ality goals, a discussion of how these goals will result in the rest oration of the waterbody’s impaired designated uses, a schedule indicating when interim and final targets are expected to be met, and a description of procedures (with thresholds) to determine whether additional (backup) corrective actio ns are needed.

# 224 Water Quality Assessment Report: Indian River Lagoon



# 3. A Description of the Proposed Man agement Actions To Be Undertaken

— names of the responsible participating en tities (government, private, others), a summary and list of existing or propos ed management activities designed to restore water quality, the geographic scope of any proposed management activities, documentation of the estimat ed pollutant load reduction and other benefits anticipated from implementa tion of individual management actions, copies of written agreements committing pa rticipants 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 the date by which designated uses will be restored), and any enforcement programs or local ordinances, if the management strategy is not voluntary.

4. A Description of Procedures for Monitoring and Reporting Results —a description of the water qua lity monitoring program to be implemented (including station locations, parameters sampled, a nd sampling frequencies) to demonstrate reasonable progress; quality assurance/quality control elements that demonstrate the monitoring will comply with Rule 62-160, F.A.C.; procedures for entering all appropriate data into STORET; the res ponsible monitoring a nd reporting entity; the frequency and format for reporting results; the freque ncy and format for reporting on the implementation of all proposed management activities; and methods for evaluating progress towards goals.

5. A Description of Proposed Corrective Actions —a description of proposed corrective actions [and any supporting docum ent(s)] that will be undertaken if water quality does not improve after impl ementation of the management actions or if management actions are not co mpleted on schedule, and a process for notifying the Department that these corre ctive actions are being implemented.



# 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

2 

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

# Water Quality Assessment Report: Indian River Lagoon 

# 225

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.



# 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 designa ted 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 Reducti ons 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

# 226 Water Quality Assessment Report: Indian River Lagoon



# 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 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 year s, 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 E: 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 (Depar tment) 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:

# Water Quality Assessment Report: Indian River Lagoon 

# 229

# 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 H ealth and Human Services (FDOH), the water management districts, local governme nts, 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 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 E.2 shows the periods of record for the Verifi ed 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).

# 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 bacteria, 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 E.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 water should be placed on the Planning List for each parameter, the chemical data were analyzed using a comput er program written to assess the data, based on criteria established in the IWR, with tw o exceptions. First, unionized ammonia data were not analyzed by the program, but rath er with an Excel spreadsheet. Second, because the full complexity of the pH criter ion 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 identific ation numbers (WBIDs ), waterbody types, and parameters obtained from the STORET Da tabase were conducted using Access, SAS statistical software, and Ar cView 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 greater than or equal to 10 percent. To be placed on the Verified List, at least a 90 percent confidence rate was required.

# 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.

# 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,

bioassessment methods involve the identific ation of a biological reference condition, based on data from unimpaired or least impacted waters in a given region.

# Water Quality Assessment Report: Indian River Lagoon 

# 233

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 smothe ring, and riparian buffer zone wi dths) was not available at the time of reporting, it was not included. Howeve r, this information is instrumental in pinpointing the causes for failed bioassessment metrics and will be included in future reporting. (see Noteworthy for a definition of riparian). 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.

For percent Diptera, the following formula was used:

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.

metric was not used.

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.

# Appendix F: Master List fo r the Indian River Lagoon Basin

Table F.1 contains the listing status of all assessed waters in the basin. It should be noted that subsequent to the update of th e 303(d) list, some waterbody segments were further subdivided to produce separate segments for lakes versus their surrounding watersheds. Therefore, Table F.1 shows the waterbody identif ication numbers (WBIDs) under which these segments were designated in the 1998 303(d) list, as well as the new or currently recognized WBIDs for them. Information in this appendix was obtaine d from an inventory of the Legacy and Modernized STORET Databases, as well as data contributed dire ctly to the Florida Department of Environmental Protection (D epartment) by individual data providers.
