FEMA Announces Federal Disaster Assistance for D.C. Following Potomac River Sewage Spill
WASHINGTON – Federal Emergency Management Agency (FEMA) announced on Saturday, February 21, 2026, that federal disaster assistance is now available to the District of Columbia to aid in response and recovery efforts following a major sewer line collapse that resulted in a significant sewage spill into the Potomac River. The assistance was approved following a request from D.C. Mayor Muriel Bowser and subsequent approval by President Donald Trump.
Timeline of the Incident
The incident began on January 19, 2026, when a section of the Potomac Interceptor, a 60-year-old, 54-mile sewer line, ruptured near the I-495 and Clara Barton Parkway interchange in Montgomery County, Maryland. This collapse led to the release of at least 250 million gallons of untreated sewage into the Potomac River and surrounding areas, including the C&O Canal.
Federal Assistance Details
President Trump’s action authorizes FEMA to coordinate all disaster relief efforts to alleviate hardship and suffering caused by the emergency. FEMA is authorized to identify, mobilize, and provide equipment and resources necessary to mitigate the impacts of the spill. The assistance will focus on Emergency Protective Measures (Category B), providing direct federal assistance under the Public Assistance program at 75 percent federal funding.
Mark K. O’Hanlon has been appointed as the Federal Coordinating Officer for federal response operations in the affected area. Further designations may be made pending requests from the state and results of additional damage assessments.
Ongoing Response and Concerns
Although the leak is largely under control, full repair of the 72-inch Potomac Interceptor pipeline is expected to take months. DC Water, in collaboration with the Environmental Protection Agency (EPA), is actively working on repairs and monitoring the river’s water quality. Officials have stated that the area’s drinking water remains safe, but recreational users of the Potomac River are advised to avoid direct contact with the water.
Political Context
Mayor Bowser declared a public emergency on February 18, 2026, formally requesting federal assistance. President Trump initially criticized the handling of the spill, blaming local Democratic leaders, including Maryland Governor Wes Moore, but ultimately approved the aid after asserting that local officials had not initially requested support. The federal government was already involved in the repair and assessment process through the EPA prior to the President’s approval.
Impacted Areas
Federal assistance extends to the District of Columbia, as well as areas within the State of Maryland and the Commonwealth of Virginia where the District of Columbia has jurisdictional responsibilities.
