These WBIDs included the following: <br />■ Blue Cypress Lake (2893V) <br />■ Padgett Branch (Class I) (3152C) <br />■ Blue Cypress Lake Drain (2893V1) <br />Blue Cypress Marsh (28938) <br />Blue Cypress Creek (3133) <br />Padgett Branch (3152B) <br />Each of these waterbodies are designated as Class I — Potable Water Supplies, except <br />Padgett Creek (31528) which is a Class III — Fish Consumption, Recreation, Propagation, <br />and Maintenance of a Healthy, Well -Balanced Population of Fish and Wildlife. <br />The IWR Run 55 dataset included data collected from the late 1960s until mid -2017. To <br />extend that record to the most recent samples, the web -based St. Johns River Water <br />Management District's (SJRWMD) Environmental Data Retrieval Tool <br />(http://webapub.sirwmd.com/agwslO/edgt/) was used to query all of the surface water <br />collected in the SJRWMD Blue Cypress Creek planning unit, which were further reduced to <br />the selected WBIDs based on station location. These. queries resulted in additional locations <br />and data not in the IWR Run 55 dataset. <br />Figure 1 shows the location of the WBIDs in relation to BCL and the density of the stations <br />extracted from the two data sources. <br />4 TASK 1 - DATA COLLECTION <br />4.1 DATA COMPILATION AND VALIDATION <br />Several actions were required to produce a single dataset for analysis: <br />1. Format the SJRWMD dataset to be compatible with the IWR dataset. This included <br />altering the field name and converting analytes listed to those used by FDEP. <br />2. Combine the two datasets. This action required checking for duplicate records since the <br />extraction from the SJRWMD database included data already.in the IWR dataset and <br />data not reported to FDEP. <br />Remove the data qualified with the any of the following data quality codes: V, F, N, O, Y, <br />H, J, K, Q, ?. Also, data qualified with a U or T signifying their values are less than the <br />method detection limit had their values changed to one-half of the reported detection <br />limit in accordance with FDEP convention. <br />3. Outliers may also be omitted from further analysis at the Users' discretion. <br />4.2 DATA SUMMARY <br />Appendix A summarizes the available water quality data. The data are organized by WBID, <br />collecting agency, and station. Additional information regarding the period of record and the <br />number of sampling days are also provided. Although there are numerous stations, many <br />lack long-term records and are likely associated with special studies. <br />08620-002-01 2 <br />September 2018 Task 1 — Data Collection and Task 3 — Trend Analysis <br />
