2.7.23.2. Data sources

Result data were downloaded from the FL STORET and WIN websites (DEP 2010f; DEP 2018h) and filtered based on the stations (DEP 2010g) in Peters Creek WBID 2444 (DEP 2014c) shown above. The filtered dataset was used to generate Table 2.24.

2.7.23.3. Discussion

Water quality data for Peters Creek are shown in Table 2.24, but the small number of samples limits any conclusions that can be drawn. Average total phosphorus, dissolved oxygen and chlorophyll-a concentrations were within acceptable limits. Historical fecal coliform levels, averaged over all the sampling sites in the Peters Creek, were above the WQC of 400 colony-forming-units (CFU) per 100 mL. As a consequence, a TMDL report was published in 2009 to address this impairment (Rhew 2009b). However, the last fecal coliform measurements available in STORET prior to 2018 date back to 2007. The average fecal coliform concentration in 2018 was lower than the WQC.

Lead has been identified as impaired (high percentage of exceedances) in Peters Creek and a TMDL report was published in 2009 (Lewis and Mandrup-Poulsen 2009) to address this issue.  While no lead data were available in 2016 and 2017, measurements from 2018 are below the WQC with no exceedances reported.

Historical water quality data for Peters Creek are available in previous versions of the River Report.

Note: Hardness-dependent freshwater criteria for cadmium, copper, lead, nickel, and zinc were generated based on a hardness concentration of 100 mg/L.
° = Number of samples below Water Quality Criteria for Dissolved Oxygen; Number of samples above Water Quality Criteria for all other parameters.
FW = freshwater; SW = saltwater (marine). Values denoted with (*) indicate a proposed criterion, which has not yet been adopted.
Values denoted with (‡) are reference values based on EPA criteria (EPA 2010b), but the water body is not regulated by this standard.
