  • East of downtown Jacksonville
  • Primary Land Use: Residential
  • Current TMDL reports:
    Nutrients, Mercury
  • Verified Impaired 2016 (final):
    None
  • WBID Area: 1.6 sq. mi.
  • Beneficial Use: Class III M (Recreational – Marine)

2.7.2.2. Data sources

Result data were downloaded from the FL STORET and WIN websites (DEP 2010f; DEP 2018h) and filtered based on the stations (DEP 2010g) in the Arlington River WBID 2265A (DEP 2014c) shown above. No water quality data for the selected parameters discussed below for the Arlington River were available in STORET for 2016-2017.  The filtered dataset was used to generate Table 2.3.

2.7.2.3. Discussion

Water quality data for the Arlington River are presented in Table 2.3. Average phosphorus levels were higher than the recently updated WQC (DEP 2015c; DEP 2016e; DEP 2016k) and the tributary has thus been identified as impaired for nutrients. Elevated levels of phosphorus may be a result of effluent from the Monterey WWTF that is discharged into the river, fertilizer runoff from the surrounding residential area, or other unidentified sources. A TMDL report for nutrients was finalized in 2009 (Magley 2009c).

The Arlington River was identified as being impaired for mercury, based on elevated levels of mercury in fish tissue; however, this is being delisted (DEP 2016h) as it has been addressed by the statewide mercury TMDL (DEP 2013c). The Arlington River is being delisted for chlorophyll-a as it has been addressed by the Nutrients TMDL (DEP 2016h).

Historical water quality data for the Arlington River are available in previous versions of the River Report.

  • Current TMDL reports: Fecal Coliform with BMAP (2010), Mercury
  • Verified Impaired 2016 (final): None
  • WBID Area: 2.9 sq. mi.
  • Beneficial Use: Class III F (Recreational – Freshwater)

2.7.14.2. Data sources

Result data were downloaded from the FL STORET and WIN websites (DEP 2010f; DEP 2018h) and filtered based on the stations (DEP 2010g) in Greenfield Creek WBID 2240A (marine) and 2240B (freshwater) (DEP 2014c) shown above. The filtered dataset was used to generate Table 2.15.

2.7.14.3. Discussion

Water quality data for Greenfield Creek are shown in Table 2.15. Average phosphorus levels were historically higher than the recently updated WQC (DEP 2015c; DEP 2016e; DEP 2016k), but data from 2017 and 2018 indicate that average concentrations of phosphorus and dissolved oxygen were within acceptable limits.  Limited recent sampling suggest that chlorophyll-a concentrations are decreasing.  However, only limited data are available in WIN and in STORET for these parameters, and these measurements are all taken from the marine portion of Greenfield Creek (2240A).  Dissolved oxygen had been removed from the verified impaired list (DEP 2016j) in Greenfield Creek. Greenfield Creek was verified impaired for mercury (DEP 2016j), but this has been addressed in the statewide mercury TMDL already in place (DEP 2013c).

A TMDL report (Wainwright and Hallas 2009a) was released to address fecal coliform, and a BMAP for Greenfield Creek (DEP 2010a) was legally adopted in August 2010. It describes sources of fecal coliform in the watershed, and completed and ongoing activities conducted by state and local agencies that are anticipated to reduce fecal coliform loading in the tributary. The Greenfield Creek watershed does not contain any permitted point sources for industrial wastewater. It contains the Girvin Road Landfill, which has been inactive since 1992; this landfill received not only solid waste, but sludge from the Neptune Beach Sewage Treatment Plant. The watershed also contains numerous outfalls for stormwater discharge. The last Annual Progress Report for this BMAP was published in 2016 and listed 20 active, ongoing projects underway by FDOT and JEA to address the BMAP in the Greenfield Creek watershed (DEP 2017c). FDEP reported improvement in the frequency of fecal coliform exceedances in the freshwater segment of Greenfield Creek, but the last fecal coliform measurements in Greenfield Creek before 2018 date back to 2008.  Recent measurements indicate ongoing issues with fecal coliform concentrations. Additional information about fecal coliform in the tributaries can be found in Section 2.6 and Table 2.2.

No recent measurements were available in WIN or STORET between 2016 and 2018 for the following parameters:

  • Arsenic
  • Lead
  • Zinc
  • Cadmium
  • Nickel
  • Copper
  • Silver

  • Verified Impaired 2016 (final): Iron (med)
  • WBID Area: 9.1 sq. mi.
  • Beneficial Use: Class III F (Recreational – Freshwater)

2.7.24.2. Data sources

Result data were downloaded from the FL STORET and WIN websites (DEP 2010f; DEP 2018h) and filtered based on the stations (DEP 2010g) in the Pottsburg Creek WBID 2265B, 2265C (freshwater), and 2265D (marine) (DEP 2014c) shown above. The filtered dataset was used to generate Table 2.25.

2.7.24.3. Discussion

Water quality data for Pottsburg Creek are shown in Table 2.25, but only a handful of measurements are available in STORET for these parameters between 2015 and 2017. Average phosphorus levels were higher than the WQC in 2017 (DEP 2015c; DEP 2016e; DEP 2016k) and near the WQC in 2018.  The percentage of measurements exceeding the WQC dropped sharply in 2018. Historically, average dissolved oxygen and chlorophyll-a were within limits, although chlorophyll-a concentrations in the marine/estuarine regions of Pottsburg Creek exceeded the WQC in 2017 and 2018.

Average fecal coliform concentrations from 1999-2012 were well above the WQC, and fecal coliform levels in this residential tributary were identified as impaired in 2004. Consequently, a TMDL for fecal coliform was published (Rhew 2009d).  A BMAP for Pottsburg Creek (DEP 2010a) was legally adopted in August 2010. It describes sources of fecal coliform in the watershed, and completed and ongoing activities conducted by state and local agencies that are anticipated to reduce fecal coliform loading in the tributary. Additional information about fecal coliform in the tributaries can be found in Section 2.6 and Table 2.2.

Annual Progress Reports for this BMAP were published annually between 2011 and 2016, listing repairs, inspections, evaluations, and other improvements conducted by JEA, the Duval County Health Department, COJ, and FDOT. In the 2016 Annual Progress Report, 34% of Pottsburg Creek fecal coliform measurements over a 7.5 year period ending June 30, 2016 exceeded the water quality criterion (400 CFU/100 mL) (DEP 2017c). Pottsburg Creek remains impaired for fecal coliform, and the size of the exceedances has increased since implementation of the BMAP; the median exceedance increased from 800 CFU/100 mL in the TMDL report to 1,532 CFU/100 mL in the first phase of the BMAP (2010-2014) (DEP 2016b). No fecal coliform data were available in STORET between 2007 and 2017, but measurements from 2018 show decreases in fecal coliform levels compared to what was reported in the BMAP documents. As of 2016, there were 24 projects either planned or currently underway by COJ, JEA, and FDOT to address the BMAP in the Pottsburg Creek watershed (DEP 2017c).

Historical water quality data for Pottsburg Creek are available in previous versions of the River Report.

  • WBID Area: 4.6 sq. mi.
  • Beneficial Use: Class III F (Recreational – Freshwater)

2.7.28.2. Data sources

Result data were downloaded from the FL STORET and WIN websites (DEP 2010f; DEP 2018h) and filtered based on the stations (DEP 2010g) in the Strawberry Creek WBID 2239 (DEP 2014c) shown above. No water quality data for the selected parameters discussed below for Strawberry Creek were available in STORET for 2015-2017.

2.7.28.3. Discussion

Water quality data for Strawberry Creek are presented in Table 2.28. No water quality data were 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 between 2012 and 2017, but measurements in 2018 indicate continued elevated fecal coliform levels.  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).

No recent measurements were available in WIN or STORET between 2016 and 2018 for the following parameters:

  • Arsenic
  • Cadmium
  • Copper
  • Lead
  • Nickel
  • Silver
  • Zinc

Historical water quality data for these parameters in Strawberry Creek are available in previous versions of the River Report.
