2.0 SUMMARY OF FINDINGSSarasota Bay Tributaries, FL WQ Survey 3/05

2 

## C The chlorophyll a and AGPT levels were low (0.45 μg/L; 1.2 mg/L) in the samples collected in Sarasota Bay at station SB1, waterbody identification number (WBID)1931 and did not indicate an imbalance of flora/fauna at the time of sampling. This WBID was originally listed for nutrient impairment on the FDEP 1998 303 (d) list. The WBID represents a small sliver of bay water near shore and the receiving waterbody, WBID 1968B, in Sarasota Bay is not impaired for nutrients or dissolved oxygen (DO) based upon the available water quality information.



## C The chlorophyll a and AGPT levels were low (0.82 & 4.3 μg/L; 2.3 & 2.0 mg/L) in the samples collected in Sarasota Bay at stations SB3 and SB2 in Sarasota Bay (WBID 1951). The AGPT level at station SB3B, also in WBID 1951, was somewhat elevated (8.7 mg/L), however, chlorophyll a levels were low (3.7μg/L). Future sampling of this drainage feature is recommended. The chlorophyll a levels in the WBID did not indicate an imbalance of flora/fauna at the time of sampling. This WBID was originally listed for nutrient impairment on the FDEP 1998 303 (d) list, however, FDEP acknowledges that there was a flaw in the basis for original 303(d) listing in 1998 because data from the wrong WBID were used in the assessment. The receiving WBID 1968B in Sarasota Bay is not impaired for nutrients or (DO) based upon the available water quality information.



## C Chlorophyll a and AGPT levels were somewhat elevated in the sample collected at station EB1 in Elligraw Bayou (WBID 1975). The chlorophyll a level was 21.0 : g/L (22.0 : g/L in the duplicate sample) and the AGPT level was 6.1 mg/L (7.1mg/L in duplicate sample). The total phosphorous (TP) level at station EB1 was 0.46 mg/L (0.47 mg/L duplicate sample). This level exceeded the 80 th percentile value of TP in Florida streams (0.46 mg/L) (FDEP 1996). A minimum DO of 4.6 mg/L was measured at this site by SESD. This WBID was originally listed for nutrients, DO, fecal coliform and total coliform impairment on the FDEP 1998 303(d) list.



## C The AGPT level was somewhat elevated in the sample collected at station SC1 in South Creek (WBID 1982A), however the chlorophyll a level was relatively low. The AGPT level was 5.0 mg/L. The TP level at station SC1 was 0.22 mg/L. This level exceeded the 90 th percentile value of TP in Florida estuaries (0.20 mg/L) (FDEP 1996). A minimum DO of 3.5 mg/L and an average of 4.3 mg/L was measured at this site by SESD. Future monitoring at this site is recommended for nutrients and DO. This WBID was originally listed for nutrients on the FDEP 1998 303 (d) list.



## C The AGPT level was somewhat elevated in the sample collected at station CC1 in Curry Creek (WBID 2009A), however the chlorophyll a level was relatively low (5.4 μg/L). The AGPT level was 5.5 mg/L. The TP level at station CC1 was 0.28 mg/L. This level exceeded the 90 th percentile value of TP in Florida estuaries (0.20 mg/L) (FDEP 1996). A minimum DO of 4.5 mg/L was measured at this site by SESD. Future monitoring at this site is recommended for nutrients and DO. This WBID was originally listed for nutrients on the FDEP 1998 303 (d) list.Sarasota Bay Tributaries, FL WQ Survey 3/05

## C The AGPT level was elevated in the sample collected at station AC1 in Alligator Creek/Direct Runoff to Bay (WBID 2042), however the chlorophyll a level was relatively low (2.5 μg/L). The AGPT level was 11.0 mg/L which is indicative of nutrient enrichment at the site. The TP level at station AC1 was 0.74 mg/L. This level exceeded the 90 th percentile value of TP found in Florida estuaries (0.20 mg/L) (FDEP 1996). Additionally, algal mats and abundant aquatic macrophytes were observed at station WC1 located in the freshwater creek draining this WBID. This WBID was originally listed for nutrients on the FDEP 1998 303 (d) list. The receiving WBID 1983A in Lemon Bay has been verified as impaired for nutrients by FDEP based upon chlorophyll a data.



## C The AGPT level was elevated in the sample collected at station WC1 in Woodmere Creek (WBID 2042), however the chlorophyll a level was relatively low (2.0 μg/L). The AGPT level was 16.8 mg/L which is indicative of nutrient enrichment at the site. The TP level at station WC1 was 0.59 mg/L. This level exceeded the 80 th percentile value of TP found in Florida streams (0.46 mg/L) (FDEP 1996). Algal mats and abundant aquatic macrophytes observed at st ation WC1 were additional indicators of nutrient enrichment and potential imbalance of flora. A minimum DO of 3.9 mg/L was measured at this site by SESD This WBID was originally listed for nutrients on the FDEP 1998 303 (d) list. The receiving WBID 1983A in Lemon Bay has been verified as impaired for nutrients by FDEP based upon chlorophyll a data. Future monitoring at this site is recommended for nutrients and DO.

A minimum DO of 2.8 mg/L was measured at this site by SESD. This WBID was originally listed for nutrients on the FDEP 1998 303 (d) list. Future monitoring at this site is recommended for nutrients and DO. The receiving WBID 1983A in Lemon Bay has been verified as impaired for nutrients by FDEP based upon chlorophyll a data.



## C The AGPT level was somewhat elevated in the sample collected at station GC1 in Gottfried Creek (WBID 2049). The AGPT level was 5.1 mg /L. The chlorophyll a level was relatively low at 4.2 : g/l. The TP level at station GC1 was 0.27 mg/L. This level exceeded the 90 th percentile value of TP in Florida estuaries (0.20 mg/L) (FDEP 1996). A minimum DO of 3.6 mg/L was measured at the site and the average value was 4.1 mg/L during this study. This WBID was originally listed for nutrients on the FDEP 1998 303 (d) list. Future monitoring at this site is recommended for nutrients and DO.Sarasota Bay Tributaries, FL WQ Survey 3/05

4 3.0 INTRODUCTION

The EPA Region 4 Water Management Division (W MD) requested technical assistance from EPA Region 4 Science and Ecosystem Support Division (SESD) in conducting a water quality survey of seven sites within Sarasota Bay located in Manatee and Sarasota Counties, and four sites within Lemon Bay located in Sarasota County, Florida. The tributaries to Sarasota and Lemon Bay addressed in this study are 303(d) listed water bodies with impairments due to nutrient enrichment and low dissolved oxygen. These waterbodies are considered a high priority for Total Maximum Daily Load (TMDL) development by the Florida Department of Environmental Protection (FDEP) and WMD. The SESD conducted water quality sampling and the WMD has initiated water quality modeling efforts for the eleven sites identified in this survey. EPA’s field support staff has also provided WMD chlorophyll a , algal growth potential test (AGPT), nutrient, dissolved oxygen and flow data for model development.

4.0 OBJECTIVES

The primary objectives of this survey were to measure the following:

• diurnal dissolved oxygen (DO), particularly at the Gottfried Creek site that is 303(d) listed for low DO. • nutrients (ammonia-nitrogen, nitrite-nitrogen, total kjeldahl nitrogen (TKN), and total phosphorus) (seven sites are 303(d) listed for nutrients). • chlorophyll a and AGPT, to complement the nutrient analyses. • acoustic doppler velocimeter (ADV) flow measurements in cubic feet per second (cfs) at select wadeable tributary sites with measurable stream flow.

Tasks to acquire these data were completed at four selected locations in Sarasota Bay and three of its tributaries, as well as at four other tributary sites to Lemon Bay, in support of WMD water quality modeling efforts. The study was designed considering the limitations of available personnel and resources. In order to more completely understand oxygen dynamics SESD collected additional data including continuous dissolved oxygen measurement and in situ water quality profiling at the Curry Creek, South Creek, Elligraw Bayou/McGraw Creek, Big Sarasota Bay/Whitaker Bayou and Sarasota Bay (S. side of causeway) stations in Sarasota Bay, and at the Gottfried Creek and Forked Creek sites in Lemon Bay.

5.0 STUDY AREA

The Sarasota Bay and its tributaries included in this study extend from Bradenton, Florida south to Englewood, Florida (Figure 1). These waters are designated as Class III surface waters for recreation and for propagation and maintenance of fish and wildlife. Gottfried Creek near Englewood, Florida is 303(d) listed for both nutrient enrichment and low oxygen. Six other sites are 303(d) listed for nutrients. These sites include Big Sarasota Bay/Whitaker Bayou, Sarasota Bay (S. side of causeway), Curry Creek, South Creek and Elligraw Bay/McGraw Creek in Sarasota Bay and Forked Creek in Lemon Bay.Sarasota Bay Tributaries, FL WQ Survey 3/05

5 6.0 METHODS

Sample locations were selected based on FDEP 303(d) listings and waterbody identification (WBID) designations established by FDEP in the 1998 305(b) re port and as modified in later years. A field reconnaissance of these locations was performed by WMD during the week of March 14, 2005 in order to identify road crossings/access within each stream reach of interest. WMD staff verified stream accessibility and the suitability of sample locations which included factors such as substrate composition and water depth. During the reconnaissance, global positioning system (GPS) coordinates were obtained at each sample location using hand held GPS units (EPA 2002, Section 17). The eleven sampling locations selected for this study are described above and shown in Figure 1.

Field sampling activities were conducted on March 22-23, 2005. The data collection was conducted using two separate crews. The specific tasks of this survey are defined in more detail in the following sections of this report.

6.1 Continuous In situ Monitoring

Continuous in situ water quality monitoring in the Sarasota Bay and its tributaries was used to provide diurnal dissolved oxygen (DO), conductivity, temperature, pH, and turbidity data. Multi parameter water quality and data logging instruments (sondes) were deployed at seven locations in the study area. These locations included SB1, SB2, EB1,SC1, CC1, FC1 and GC1, respectively (Table 1, Figure 1). Sondes were deployed at mid-depth of the main hydraulic conveyance of the water body by either securing them to rebar driven into the stream substrate or by tethering them to bridges. Sondes used for this study were equipped with pH, dissolved oxygen, temperature, conductivity, and turbidity probes.

Data records of pH, DO, temperature, conductivity and turbidity concentration were obtained at 15 minute intervals throughout the monitoring period. Sondes were deployed on Tuesday, March 22 nd

, and retrieved on Wednesday afternoon, March 23 rd . Deployment and retrieval times were recorded in a field log book by each sampling team. Each team also collected AGPT samples to determine the algal limiting nutrient, chlorophyll a , and nutrients at each station. Flow was measured at EB1 & WC1.

Monitoring equipment was calibrated according to Ecological Assessment Standard Operating Procedures and Quality Assurance Manual (EASOPQAM) (EPA 2002) and manufacturer specifications. Prior to deployment, the instruments were calibrated and results entered in each team’s field log book. Pre-deployment calibrati on included adjusting the instrument output, as needed, using reference standards (pH, conductivity, turbidity) and an azide modified Winkler titration (DO) or air calibration for DO according to manufacturer instructions. At the end of the study, the instruments were again checked against these standards and the results entered in each team’s field log book.Sarasota Bay Tributaries, FL WQ Survey 3/05

8 Field log books were maintained by the crew(s) deploying/retrieving the monitors for the duration of the study. Following return to the SESD office, the log books have been maintained in a central location by the project leader. Samp ling protocol followed EASOPQAM (EPA 2002). All data logged during the period between deployment and retrieval was downloaded from the data sondes in an electronic spreadsheet format (Appendix A). Electronic spreadsheets include a summary (e.g., average, maximum, minimum) of the recorded data collected from 3/22/05 through 3/23/05.

6.2 Chlorophyll a and AGPT Sampling

Depths in the Sarasota Bay tributary sites were generally wadeable. Depth in the Sarasota Bay/Whitaker Bayou area, Curry Creek, and Godfried Creek were non-wadeable and sampled by boat. Because of depth limitations, less vertical sampling within the water column of the wadeable tributary sites was necessary. AGPT sa mples were grabbed at a one foot depth below the water surface at all sites.

Sampling protocol followed SESD Standard Oper ating Procedure (SOP) manuals and/or Standard Methods, 20th Edition. Chlorophyll samples were filtered using a hand pump at < 15 psi. Enough sample was filtered (measured by volumetric cylinder) to produce color on the filter (typically 100 ml). After each filtering, the funnel wa s rinsed with DI water. The filter was then folded upon itself, wrapped in aluminum foil, labeled with station name, date, time, depth, and volume filtered on labeling tape and stored in a water-tight container on ice in the dark. All chlorophyll processing was performed in the field under the direction of the Task Leaders. Processed chlorophyll samples were kept in an iced cooler and transported to the SESD laboratory at the end of the survey. AGPT samples were kept on ice and transported to the SESD laboratory on March 23, 2005.

Results of chlorophyll analysis have been stored in R4LIMs. Chlorophyll and AGPT sampling results have been included in this report. Field log books were maintained by the Module Leader throughout the survey. The log books and records will be maintained in the project file.

6.3 Hydrology

Stream depth and width were determined with a wading rod and cloth/steel engineers tape. Flow was measured with a SonTek® Flow Tracker handheld acoustic doppler velocimeter (ADV® ). Velocities and calculated streamflow for EB1 and WC1 were recorded in a field book and include pertinent station information (station number, date, time, etc.). Calibration and use of these instruments was performed in accordance w ith SESD Ecological Assessment Branch (EAB) SOPs (EPA, 2002) and the manufacturer’s instructi ons. The flow measured at station EB1 was approximately 0.5 cubic feet per second (cfs) and the flow measured at WC1 was 2.2 cfs.

6.4 In situ Profiling

In situ profiling, measurement of ambient dissolved oxygen, pH, conductivity, temperature and turbidity at incremental depths throughout the water column, was used to supplement data acquisition at stations with continuous monitors.

Ambient water quality parameters including pH, conductivity, dissolved oxygen, temperature, and turbidity was measured using a Yellow Springs Instruments® (YSI) model 6920 data sonde positioned just below the water surface in an undisturbed (upstream) area of the study station.Sarasota Bay Tributaries, FL WQ Survey 3/05

9 In situ profiles were obtained as necessary using YSI model 6920 data sondes. These instruments were manually deployed to obtain readings from surface to bottom at one foot increments. Profiling protocol followed EASOPQAM (EPA 2002) guidelines. The location, date, time, and in situ measurements of each profile were recorded in the field data book. Field log books were maintained by each profiling crew leader for the duration of the study. Upon return to the SESD office, the log books will be maintained in a central location by the project leader.

Water quality monitoring equipment was calibrated according to EASOPQAM (EPA 2002) and/or manufacturer’s specifications using precise standards for pH, conductivity, turbidity and either air calibration or azide modified Winkler titration for dissolved oxygen. Calibration checks of profiling instruments occurred at the beginni ng and end of each day. Recalibration of the profiling instruments was conducted any time when/if the observed instrument DO reading varied greater than ± 0.2 mg/L of the Winkler titrated DO in the calibration water. This information was recorded in the field book(s). Backup monitors were carried by each profiling crew in case of primary instrument failure.

All in situ data was transcribed from the field l og books to electronic spreadsheet format. Transcribed data was verified prior to report completion. Field log books will be maintained in the project file. Electronic files of this data have been provided in this report (Appendix A).

6.5 Nutrient Sampling

Nutrient grab samples were collected within 1 foot of the surface at each of the study stations listed in Table 1 and depicted in Figure 1. Nutrient samples collected from each site were analyzed by the SESD laboratory for the parameters described in Table 4.

The nutrient samples were processed in the field by SESD according to standard operating procedures. Sample processing included preservation of samples with 10% H 2 SO 4 , and labeling/custody documentation. The samples were transported by vehicle to the SESD laboratory on 3/23/05. Field data books were maintained for the duration of the survey.

7.0 DOCUMENTATION AND RECORDS MANAGEMENT

Data collected during field sampling activities was managed and stored by the sampling team members. Upon completion of sampling activities, all documents/records obtained during the field investigation were delivered to the proj ect leader who organized, labeled, and maintained them during preparation of the data report. U pon completion of the report, project records will be submitted to the SESD Records Room. Access to analytical results for this project shall be available to US EPA project team members through the Region 4 Laboratory Information Management System (R4LIMS).

This report includes a description of the locations sampled, flow measurement and sonde results including tables/graphs, and a discussion of field activities. Field data logs will not be included in this report, but will be maintained in SESD Cent ral Records in case they are needed at a later date.Sarasota Bay Tributaries, FL WQ Survey 3/05

10 8.0 QUALITY ASSURANCE AND QUALITY CONTROL

Quality control (QC) procedures were used in the field and laboratory to ensure that reliable data were obtained. When performing this field sampli ng effort, precautions were taken to prevent the cross-contamination of sampling equipment, sample bottles, and other equipment that could have compromised sample integrity. Field equipment rinse blanks were collected for samples that were filtered in the field to demonstrate that the equipment was free of contamination. Handling and custody of samples followed guidelines described in EASOPQAM (US EPA 2002, Section 2).

9.0 DATA VALIDATION/VERIFICATION

The WMD will make the ultimate decision regarding the acceptable and appropriate use of the data for water quality modeling or other purposes. As such, all study data were reported.

10.0 PROJECT MANAGEMENT

Measurement of in situ water quality profiling including continuous dissolved oxygen, nutrients, chlorophyll a , AGPT and flow was managed through the SESD Ecological Assessment Branch with cooperation and technical support from WMD.
