The Potomac River, a primary drinking water source for more than 5 million people in the Washington, D.C. metropolitan area, is facing severe contamination from both sewage and jet fuel, according to recent documentation. A major collapse of the Potomac Interceptor sewer line triggered a catastrophic sewage leak, while roughly 32,000 gallons of jet fuel were released nearby, with about 22,000 gallons still unaccounted for in soil and groundwater. Maryland environmental testing found PFAS levels in Piscataway Creek fish up to 1.4 million times above EPA drinking-water health standards. Maryland’s congressional delegation has formally pressed the Air Force and DC Water for answers.
