2.7.6.2. Data sources

Result data were downloaded from the FL STORET website (DEP 2010e) and filtered based on the stations (DEP 2010f) in Butcher Pen Creek WBID 2322 (DEP 2014d) shown above. The filtered dataset was used to generate Table 2.7.

2.7.6.3. Discussion

Water quality data for Butcher Pen Creek are shown in Table 2.7. Average phosphorus levels were higher than the recently updated WQC (DEP 2015d; DEP 2016e; DEP 2016k). The average fecal coliform level exceeds the WQC of 2.6, which is the logarithm of the state maximum of 400 colony-forming-units per 100 mL (Table 2.7). As a result, a TMDL report was published in 2005 (Wainwright 2005a) to address this issue. 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. Butcher Pen Creek was previously impaired for chlorophyll-a, but annual levels have fallen below the nutrient threshold, and it has been delisted for chlorophyll-a (DEP 2016h).

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.
