A boil water advisory for parts of southern Prince George’s County, affecting Accokeek and Clinton areas, was lifted after a 16-inch water main break caused a loss of pressure. The advisory, lifted at 9 p.m. Friday, impacted around 3,600 customers, who were advised to flush their cold water lines.

WSSC Water issued a boil water advisory for Accokeek and Clinton in southern Prince George’s County after a 16-inch water main break caused pressure loss. Around 3,600 customers are affected, and a water station has been established at Accokeek Academy. The advisory remains until water safety is confirmed.

DC Water has initiated emergency repairs on a corroded 1,700-foot section of the Potomac Interceptor sewer line near Lock 22 on the C&O Canal in Maryland. A spill at this location could threaten the drinking water intakes for WSSC Water and Washington Aqueduct, though Fairfax Water’s intake would remain unaffected. Crews are installing a temporary bypass system while the compromised pipe is replaced, with work expected to last through September.

A $25 million regional study called 'Secure the Source' is being launched by WSSC Water, the Washington Aqueduct, and Fairfax Water to identify a large-scale backup water supply for the D.C. area, addressing vulnerabilities in the region’s reliance on the Potomac River. The study aims to ensure emergency water access for weeks if the river becomes unusable due to drought or contamination.

DC Water is initiating emergency repairs on a deteriorating section of the Potomac Interceptor sewer line in Potomac, Maryland, to protect drinking water intakes for WSSC Water and the Washington Aqueduct. Inspections revealed structural issues like corrosion and exposed rebar, prompting immediate action. Repairs, starting June 15, 2026, will include building an above-ground bypass pipeline and monitoring equipment, with construction expected to continue until September 2026.
