2.7.28.2. 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 the Strawberry Creek WBID 2239 (DEP 2014c) shown above. The filtered dataset reflects water column concentrations and was used to generate Table 2.28. No water quality data for the selected parameters discussed below for Strawberry Creek were available in STORET for 2017.

2.7.28.3. Discussion

Water quality data for Strawberry Creek are presented in Table 2.28. Water quality data for metals is extremely limited, with only one measured sample in 2019 and no other data available in WIN or STORET for metals since 2007. Historical fecal coliform levels, averaged over all the sampling sites in Strawberry Creek, were above the WQC of 400 colony-forming-units per 100 mL. Thus, a TMDL report for fecal coliform in Strawberry Creek was published in 2009 (Rhew 2009e). (Note: the data analyses in the TMDL are based on different criteria than that used in this report). No new fecal coliform measurements were reported in STORET in 2017, but measurements in 2018 and 2019 indicate continued elevated fecal coliform levels, with average fecal coliform levels exceeding the WQC.  In 2018, the City of Jacksonville planned to implement a monitoring program for Strawberry Creek as part of a bacteria pollution control plan in concert with efforts related to stormwater management (COJ 2017).

Historical water quality data for these parameters in Strawberry 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.
