Source Water Assessment Program (SWAP)

Under the provisions of the Safe Drinking Water Act (SDWA), states are required to develop comprehensive Source Water Assessment Programs that: 

  • identify the watersheds that supply public tap water
  • provide an inventory of contaminants present in the watershed
  • assess susceptibility to contamination in the watershed

The assessment consists of maps of the watershed area that were evaluated, an inventory of known land use activities, and documentation of any known source water contamination.

Source water assessments for Fairfax Water’s watersheds are conducted by the Virginia Department of Health (VDH). Based on the criteria developed by the state, the Potomac River and the Occoquan Reservoir were determined to be of high susceptibility to contamination. This determination is consistent with the state’s finding of other surface waters, such as rivers, lakes, streams, throughout the Commonwealth of Virginia.

For more information about source water assessments, see our Fact Sheet and Frequently Asked Questions.
