Potomac River Basin Drinking Water Source Protection Partnership The Potomac River Basin Drinking Water Source Protection Partnership is a multi-jurisdictional collaboration focused on safeguarding public water supply intakes, source waters, and raw water quality across the Potomac River watershed. It brings together federal, state, interstate, municipal, and nonprofit actors to coordinate science, planning, and response among stakeholders in the Chesapeake Bay watershed, Washington metropolitan region, and mid-Atlantic corridor.
The Partnership coordinates among agencies such as the U.S. Environmental Protection Agency, U.S. Geological Survey, National Oceanic and Atmospheric Administration, Food and Drug Administration, U.S. Army Corps of Engineers, and state water utilities including Virginia Department of Environmental Quality, Maryland Department of the Environment, and District of Columbia Water and Sewer Authority to reduce risks to drinking water intakes. It links municipal systems like Washington Aqueduct, regional commissions such as the Interstate Commission on the Potomac River Basin, conservation organizations including Potomac Conservancy, Chesapeake Bay Foundation, and academic centers like the University of Maryland, George Mason University, and Georgetown University for coordinated source protection. The Partnership addresses issues that involve statutes and programs such as the Safe Drinking Water Act, Clean Water Act, Chesapeake Bay Program, and regional planning efforts by entities like the Metropolitan Washington Council of Governments.
The Partnership emerged from efforts in the early 2000s to respond to drinking water contamination events and to implement source protection recommendations following incidents that engaged agencies such as the Centers for Disease Control and Prevention, U.S. Department of Homeland Security, and local utilities like Alexandria Renew Enterprises. It was shaped by prior initiatives involving the Potomac River Basin Compact, the Interstate Commission on the Potomac River Basin agreements, and federal funding streams from programs administered by the U.S. Environmental Protection Agency Office of Ground Water and Drinking Water. Stakeholders drawn from municipalities including Fairfax County, Virginia, Montgomery County, Maryland, Prince George's County, Maryland, and the City of Rockville, Maryland formalized collaborative protocols to coordinate monitoring, modeling, and emergency response.
Governance is typically executed through a steering committee and technical workgroups composed of representatives from federal agencies such as the U.S. Geological Survey and Environmental Protection Agency, state agencies including the Virginia Department of Health, Maryland Department of the Environment, and local utilities like the Washington Suburban Sanitary Commission. Membership spans interstate bodies such as the Interstate Commission on the Potomac River Basin, nonprofit organizations including Nature Conservancy chapters active in the region, academic entities like the Smithsonian Institution research staff and university hydrology programs at Johns Hopkins University, and municipal drinking water suppliers such as City of Frederick, Maryland and Fairfax Water. Decision-making uses memoranda of understanding modeled on cooperative arrangements used by the Potomac Conservancy and regional planning organizations like the National Capital Planning Commission.
The Partnership implements source protection initiatives modeled on state source water protection programs under the Safe Drinking Water Act and integrates pilot projects funded through federal mechanisms such as the U.S. Department of Agriculture conservation grants and EPA Water Security Initiative grants. Programs include watershed management planning coordinated with the Chesapeake Bay Program and nutrient reduction efforts aligned with Total Maximum Daily Load implementation. Initiatives also encompass emergency contaminant response planning in collaboration with the Federal Emergency Management Agency, cross-jurisdictional spill response exercises with the U.S. Coast Guard, and public outreach campaigns involving environmental NGOs like Sierra Club and community partners such as Anacostia Watershed Society.
Scientific activities emphasize hydrology, water quality, and contaminant fate studies conducted by the U.S. Geological Survey, university laboratories at Virginia Tech and Pennsylvania State University, and regional monitoring networks run by the Interstate Commission on the Potomac River Basin. Monitoring targets include nutrients, pathogens, algal bloom precursors, and emerging contaminants assessed with methods developed by agencies like the Centers for Disease Control and Prevention and research consortia associated with the National Institutes of Health. Modeling and data integration draw on tools used by the Chesapeake Bay Program and hydrodynamic models applied by the Army Corps of Engineers to inform intake vulnerability mapping and source water protection zones.
The Partnership forges alliances with municipal water suppliers such as Alexandria, Virginia utilities, regional planning entities like the Metropolitan Washington Council of Governments, conservation organizations including Potomac Conservancy and Chesapeake Bay Foundation, and federal partners including EPA Region 3. Engagement extends to tribal stakeholders, county governments including Loudoun County, Virginia and Frederick County, Maryland, business groups, and research institutions such as George Washington University to align land use, stormwater, and agricultural practices with source protection objectives. Public communication leverages outreach channels of nonprofits like Friends of the Potomac and local health departments.
Policy efforts integrate source protection elements into planning frameworks governed by statutes and programs such as the Safe Drinking Water Act, Clean Water Act restoration funding, and regional implementation plans coordinated by the Interstate Commission on the Potomac River Basin and the Chesapeake Bay Program. Funding streams include federal grants from the U.S. Environmental Protection Agency, state revolving funds administered by Maryland Department of the Environment and Virginia Department of Environmental Quality, and philanthropic support from foundations active in the region such as the Rockefeller Foundation and Kresge Foundation. Planning aligns with municipal capital improvement programs of utilities like Washington Suburban Sanitary Commission and emergency preparedness protocols of the Federal Emergency Management Agency.
