The Interstate Commission on the Potomac River Basin (ICPRB) is an advisory, non-regulatory interstate compact agency serving the Potomac basin states of Maryland, Pennsylvania, Virginia, West Virginia, and the District of Columbia, with the federal government as a member. Established by an act of Congress in 1940 and expanded in 1970 to address water resources and related land issues across jurisdictions, the organization focuses on protecting and improving the basin’s waters and related resources through science, regional cooperation, and education. It operates from Rockville, Maryland, and draws on a multidisciplinary staff of environmental professionals to inform its work and collaborate with broader programs such as the Chesapeake Bay Program. The ICPRB’s mission centers on sustaining water quality and regional well-being for more than six million people who rely on the Potomac River, balancing pollution controls with growing regional development. In recent years, the commission has continued to address emerging threats such as population growth, land use change, and nutrient and sediment enrichment that require coordinated actions across jurisdictions.
