2.7.6.2. Data sources

Data were downloaded from the FL STORET and WIN websites (DEP 2010f; DEP 2018c) and filtered based on the stations (DEP 2010g) in Butcher Pen Creek WBID 2322 (DEP 2014c) shown above. The filtered dataset reflects water column concentrations and 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. Historical phosphorus levels were higher than the recently updated WQC (DEP 2015c; DEP 2016e; DEP 2016k), but recent phosphorus data have trended downwards.  Chlorophyll-a levels have increased the past two years.  Butcher Pen Creek was previously considered impaired for chlorophyll-a, but it was delisted for chlorophyll-a in 2016 (DEP 2016h).

The average fecal coliform level exceeded the WQC of 400 colony-forming-units per 100 mL in each of the last three years (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). The last Annual Progress Report for this BMAP was published in 2016 and listed 16 active, ongoing projects underway by FDOT and JEA to address the BMAP in the Butcher Pen Creek watershed (DEP 2017c).  While fecal coliform levels have remained high over the past three years, the average measurements have decreased. In 2018, FDEP piloted microbial source tracking strategies in selected impaired waterbodies.  They found that the strategies used could be used to narrow down areas suspected of containing sources that actively contribute fecal indicating bacteria to water in order to identify and remediate them, but this work is resource-intensive.  Butcher Pen Creek was found to have known sources of untreated human waste present (DEP 2019a). Additional information about fecal coliform in the tributaries can be found in Section 2.6 and Table 2.2.

Historical water quality data for Butcher Pen 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.
° = Number of samples below Water Quality Criteria for Dissolved Oxygen; Number of samples above Water Quality Criteria 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.
