In April 2004 the Virginia Department of Environmental Quality (DEQ) updated the designations of waters in Loudoun County that are impaired or threatened as required under the Federal Clean Water Act, Section 303(d). Impaired waters are unsuited for their intended use for aquatic life and recreation, and threatened waters are those that require additional monitoring to document an impairment. DEQ publishes these lists to help local communities establish priorities for stream water quality protection and restoration programs and projects. County agencies and citizen environmental stewardship groups have been monitoring Loudoun streams for several years. Loudoun Watershed Watch (LWW) has compiled these monitoring data from agencies a nd groups in Loudoun County. LWW is working to have more locally generated data included in DEQ reports.
