2.7.2.2. Data sources

Result data were downloaded from the FL STORET website (DEP 2010e) and filtered based on the stations (DEP 2010f) 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 2015-2017.

2.7.2.3. Discussion

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).

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