2.7.25.2. Data sources

Result data were downloaded from the FL STORET website (DEP 2010e) and filtered based on the stations (DEP 2010f) in the Ribault River WBID 2224 (DEP 2014c) shown above. No water quality data for the selected parameters discussed below for the Ribault River were available in STORET for 2015-2017.

2.7.25.3. Discussion

No water quality data are available for the Ribault River after 2012, and the most recent measurements of metals and phosphorus were from 2007.  The Ribault River is located in a highly residential area and has historically been a contributor to elevated levels of phosphorus found in the tributary. High levels of chlorophyll-a have also been measured, but Ribault River has not been designated impaired (DEP 2016h). Iron has been added to the verified impaired list (DEP 2016j).

Historical fecal coliform levels, averaged over all the sampling sites in the Ribault River, were elevated. A TMDL report for fecal coliform in the Ribault River was published in 2006 (Wainwright 2006a), and a BMAP is under development. (Note: the data analyses in the TMDL are based on different criteria than that used in this report).  In 2014, the City of Jacksonville implemented a monitoring program for the Ribault River as part of a bacteria pollution control plan in concert with efforts related to stormwater management (COJ 2017).  However, the latest fecal coliform data available in STORET date back to 2012

No recent measurements were available in STORET between 2015 and 2017 for the following parameters:

  • Dissolved oxygen
  • Nitrate-nitrite nitrogen
  • Total phosphorus
  • Chlorophyll-a
  • Arsenic-Cadmium
  • Copper
  • Lead
  • Nickel-Silver
  • Zinc
  • Fecal Coliform
  • Turbidity

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