Figure 2.29
Figure 2.30 The Broward River Tributary (WBID 2191A/B).
  • Between downtown and Jacksonville International Airport (JIA)
  • Primary Land Use: Residential/Forested
  • Current TMDL reports: Mercury
  • Verified Impaired 2016 (final): Fecal Coliform (2191B low)
  • WBID Area: 14.4 sq. mi.
  • Beneficial Use: Class III M/ F (Marine – 2191B, Freshwater – 2191A)

2.7.5.2. Data sources

Result data were downloaded from the FL STORET website (DEP 2010e) and filtered based on the stations (DEP 2010f) in Broward River WBID 2191A/B (DEP 2014c) shown above. No water quality data for the selected parameters discussed below for the Broward River were available in STORET for 2015-2017.

2.7.5.3. Discussion

Historically, average phosphorus levels were higher than the 2010 updated WQC (DEP 2015c; DEP 2016e; DEP 2016k). Historical maximum fecal coliform level at times exceeded the WQC of 400 colony-forming-units per 100 mL, and as a result, WBID 2191B is considered impaired for fecal coliform.  However, the last fecal coliform measurements reported for the Broward River date back to 2008, and no more recent data were available. The Broward River was identified as being impaired for mercury, based on elevated levels of mercury in fish tissue; however, it is being delisted (DEP 2016h) as it has been addressed by the statewide mercury TMDL (DEP 2013c).

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 Broward River are available in previous versions of the River Report.
