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 2014d) 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. Average total nitrogen, total phosphorus, dissolved oxygen and chlorophyll-a concentrations were within acceptable limits. The fecal coliform level, averaged over all the sampling sites in the Peters Creek, is above the critical level of 2.6, which is the logarithm of the state maximum of 400 colony-forming-units per 100 mL. As a consequence a TMDL report was published in 2009 to address this impairment (Rhew 2009a). In addition, even though the mean concentration of lead is significantly lower than the freshwater water quality criteria, 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.

Note: Hardness-dependent freshwater criteria for cadmium, copper, lead, nickel, and zinc were generated based on a hardness concentration of 100 mg/L.
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.
