Potomac River advisory lifted as sewer-line repair work continues in Washington, DC
Washington, DC – March 3, 2026 – Potomac River advisory lifted after testing improves; DC Water repairs continue as MedStar reports a rescue.
Washington, DC is easing back into Potomac River recreation after DC Health lifted its recreational advisory on March 2, citing consistent water-quality results within safe ranges for recreation.
Potomac River: advisory lifted, but monitoring continues
DC Health said recent testing shows E. coli levels in the District’s portion of the Potomac River meet the U.S. Environmental Protection Agency’s standard used for recreational contact and have stayed within a typical range for at least 21 days since the last overflow event tied to the Potomac Interceptor collapse.
Officials emphasized the update applies only to waters within the District. Separate guidance may remain in place in neighboring jurisdictions. DC Health also reiterated that swimming in the District’s rivers without a permit is not allowed.
District agencies said the city’s drinking water has not been affected because drinking-water intakes are upstream of the break.
DC Water: repair and restoration work moves forward
In a March 1 update, DC Water reported three weeks with no overflows reaching the river since Feb. 8 and described ongoing cleanup and stabilization work at the collapse area in the C&O Canal corridor. The utility said the National Park Service issued a special use permit on Feb. 28 for repair, rehabilitation and environmental restoration work in the impacted park area.
DC Water said crews are cleaning pipe sections upstream and downstream of the damaged area and preparing to apply a geopolymer lining, a concrete-like material intended to reinforce the pipe. The utility said this phase keeps its emergency repair timeline on track for mid-March, when it expects to restore full wastewater flow and end the need for bypass pumping.
Environmental restoration work described by DC Water includes clearing contaminated debris and starting to haul contaminated brush and soil for proper disposal, with work dependent on weather conditions.
Community scrutiny: calls for transparency
Potomac Conservancy issued a March 2 statement urging additional public accountability and communication from DC Water, including a call for an independent third-party investigation and sustained water-quality testing through the summer as repairs and remediation continue.
Hospital update: confined-space rescue at MedStar Washington Hospital Center
DC Fire and EMS responded early March 1 to a confined-space rescue at MedStar Washington Hospital Center, where officials said a patient jumped about 20 feet down an interior utility shaft and was rescued after a roughly 70-minute operation. The patient was reported to have serious injuries, and officials did not release further details.
