18.104.22.168. 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 2014d) shown above. The filtered dataset was used to generate Table 2.3.
Water quality data for the Arlington River are shown in Table 2.3. Average phosphorus levels were higher than the recently updated WQC (DEP 2015d; 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 2013e). The Arlington River is being delisted for chlorophyll-a as it has been addressed by the Nutrients TMDL (DEP 2016h).

FW = freshwater; SW = saltwater (marine). Values denoted with (*) indicate a proposed criterion, which has not yet been adopted.
Values denoted with (‡) are reference values based on EPA criteria (EPA 2010b), but the water body is not regulated by this standard.
