Report on Fairfax County Streams (2005-2007)
The annual reports on Fairfax County’s streams present summaries of water quality data and assessments of current stream conditions and trends countywide. They document overall stream conditions based on the abundance and diversity of fish and aquatic insects. In addition, the potential human health risk associated with wading or swimming in streams is assessed based on fecal-associated bacteria.
These reports are developed as part of the stream quality assessment program to meet the goals and requirements of the stormwater management program; the Board of Supervisors’ environmental improvement program; and local, state and federal regulations, including the Chesapeake Bay Act, the county's Municipal Separate Storm Sewer System (MS4) Permit and the federal Clean Water Act.
Starting in 2008, this information may be found in the Stormwater Status Reports.
