Update: March 2, 2026
The District Department of Health (DC Health) has lifted the recreational advisory for the Potomac River in Washington, DC, effective immediately.
Ongoing water quality monitoring indicates that bacterial levels have returned to safe ranges for recreational use. The advisory was originally issued following the collapse of a section of the Potomac Interceptor sewer line. Consistent testing results now confirm that conditions have improved and the river is safe for recreation.
Residents may resume permitted recreational activities in the District’s portion of the river, including boating, kayaking, fishing, and other water-based recreation. Swimming remains legally prohibited.
Please note that this advisory applies only to waters within the District of Columbia. For areas outside the District’s boundaries, residents should follow guidance issued by neighboring jurisdictions.

As of February 18, 2026
Drinking water remains safe and has not been impacted by the sewage release. However, the District advises avoiding contact with Potomac River water, and residents should keep children and pets away from the river. The District is closely monitoring the situation and will share updates as new information becomes available.
Vulnerable Populations: Include people who may come into contact with sewage-contaminated water, such as those doing outdoor activities like boating, fishing, or swimming, people with pets that go outside, young children under 5, and workers handling sewage water (utility workers, researchers, emergency personnel, etc.).
Some groups are also at higher risk of serious illness if exposed. This includes young children, pregnant people, adults over 50, people with weakened immune systems or on certain medications, and anyone with open cuts or wounds.
