2.7.12.2. Data sources

Result data were downloaded from the FL STORET website (DEP 2010e) and filtered based on the stations (DEP 2010f) in Ginhouse Creek WBID 2248 (DEP 2014d) shown above. The filtered dataset was used to generate Table 2.13.

2.7.12.3. Discussion

Water quality data for Ginhouse Creek are shown in Table 2.13; note, however, that no metals data were available. Average fecal coliform levels are elevated and above the WQC, but Ginhouse Creek has been identified as impaired for fecal coliform.

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.
