Who We Are

Potomac River Basin Drinking Water Source Protection Partnership

The founding members of the Partnership include water utilities serving nearly 5 million residents of the Potomac basin as well as agencies representing Virginia, West Virginia, Maryland, Pennsylvania, the District of Columbia, and the U.S. EPA. The effort to form the Partnership began after the completion of source water assessments for the Washington, D.C., metropolitan area, when the water suppliers who share the Potomac River as their source met with state and federal representatives to share their results and discuss next steps. After a series of meetings, the concept of the Potomac Drinking Water Source Protection Partnership evolved from the shared vision of all the stakeholders to protect drinking water in the basin.
