2.7.23.2. Data sources

Result data were downloaded from the FL STORET website (DEP 2010e) and filtered based on the stations (DEP 2010f) in Peters Creek WBID 2444 (DEP 2014c) shown above. The filtered dataset was used to generate Table 2.21.

2.7.23.3. Discussion

Water quality data for Peters Creek are shown in Table 2.21, 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 2009a). However, the last fecal coliform measurements in STORET date back to 2007, and no newer data are available to assess the status of fecal coliform in Peters Creek.

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.  However, no recent lead data were available in STORET.

No recent measurements were available in STORET between 2015 and 2017 for the following parameters:

  • Arsenic
  • Lead
  • Zinc
  • Cadmium
  • Nickel
  • Copper
  • Silver
  • Fecal Coliform

Historical water quality data for these parameters in 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.
º = Number of samples below WQC for Dissolved Oxygen, Number of samples above WQC 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.
§ = No water quality criterion has been established for Nitrate-Nitrite nitrogen. No Total Nitrogen data were available in STORET for 2015-2017.
