The White House took decisive action on Friday, officially designating the U.S. Environmental Protection Agency as the lead federal authority in the ongoing Potomac Interceptor collapse. The move comes after more than 240 million gallons of raw sewage spilled into the Potomac River following a major pipe failure in Maryland late last month.
EPA Administrator Lee Zeldin has appointed Assistant Administrator for Water Jessica Kramer to serve as the Senior Response Officer. In this role, Kramer will manage the coordination between various federal, state, and local agencies to contain the spill and protect the region’s water supply.
While the crisis began in mid-January, federal officials noted that the District of Columbia only requested formal assistance this week. Prior to that request, neither Maryland nor D.C. had asked for federal intervention.
The 72-inch wide sewer pipe, which is managed by DC Water, typically carries roughly 60 million gallons of wastewater daily from Virginia and Maryland to the Blue Plains treatment plant. The collapse occurred on January 19, leading to weeks of untreated discharge. To mitigate the environmental damage, a bypass system was activated on January 25. This system uses a portion of the C&O Canal to catch and redirect the sewage back into an undamaged section of the interceptor for proper treatment.
Current projections suggest the permanent repairs will be finished by mid-March. The EPA has also been tasked with ensuring the area is fully cleaned up before the upcoming America250 celebrations, which are expected to draw large crowds to the Potomac waterfront.
Furthermore, the agency will oversee an evaluation of the entire interceptor line to catch any other potential weak points before they fail.
Despite the scale of the spill, the Washington Aqueduct reports that drinking water for the D.C. metro area remains safe. Officials explained that the sewage entered the river downstream from the main water intake facilities. A secondary, older intake located downstream from the spill has been offline since the fall of 2025, preventing any contamination from reaching the local taps.
Administrator Zeldin described the situation as a crisis of historic proportions and emphasized that the EPA is committed to a transparent and fast-tracked recovery. The agency plans to work closely with DC Water to ensure that both the immediate repairs and the long-term remediation of the river are handled efficiently to prevent a repeat of the disaster.
