2.7.3.2. Data sources

Result data were downloaded from the FL STORET website (DEP 2010e) and filtered based on the stations (DEP 2010f) in Big Fishweir Creek WBID 2280 (DEP 2014d) shown above. The filtered dataset was used to generate Table 2.4.

2.7.3.3. Discussion

Water quality data for Big Fishweir Creek are shown in Table 2.4. A TMDL report (Wainwright and Hallas 2009a) was released in 2009 to address Fecal coliform and as a result has been delisted from the Impaired Waters list (DEP 2016h) (Note: the data analyses in the TMDL are based on different criteria than that used in this report). Subsequently, a BMAP to address this issue was legally adopted (DEP 2009b). Annual Progress Reports for this BMAP were issued in 2011 (DEP 2011a), 2012 (DEP 2012) and 2013 (DEP 2014b); they list repairs, inspections, evaluations, and other improvements conducted by JEA, the Duval County Health Department, COJ, and FDOT. Big Fishweir Creek has been listed as Impaired for high levels of iron (DEP 2016j).

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.
