Clean water is essential for human and animal life, for commerce and industry, and for recreation. Drinking water in the District of Columbia comes from the Potomac River, upstream of the District.
The District is a part of the Chesapeake Bay Watershed. Our main waterways are the Potomac and Anacostia Rivers, Oxon Run, and Rock Creek. DOEE administers several programs dedicated to monitoring and improving water quality within the District.
