PFAS Contamination and Sewage Incidents in the Potomac Basin

The Potomac watershed faces significant challenges to drinking water quality due to PFAS contamination and sewage inflows. Among the affected areas is the Occoquan Reservoir, which serves as a drinking water source for approximately one million people in Northern Virginia. Additionally, a historical pipe burst of the Potomac Interceptor was highlighted, which led to significant sewage releases.
