  • 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.

2.7.28. Strawberry Creek

2.7.28.1. About the Strawberry Creek

Figure 2.62
Figure 2.63 The Strawberry Creek Tributary (WBID 2239).
  • Flows into the Arlington River
  • Primary Land Use: Residential
  • Current TMDL reports: Fecal Coliform, Mercury
  • Verified Impaired 2016 (final): None
  • 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.
