Trump Approves Federal Emergency After Massive Potomac River Sewage Spill

A catastrophic sewage spill has triggered a federal emergency in Washington, D.C., after the rupture of a major pipeline in Maryland in January 2026. The disaster released over 950 million liters (more than 250 million gallons) of raw sewage into the Potomac River, contaminating the region’s main drinking water source and prompting urgent local and federal action. President Donald Trump approved a disaster declaration on February 21, enabling federal agencies to provide disaster aid, equipment, and resources for pollution control. The incident has exposed severe vulnerabilities in the area’s aging infrastructure, sparked criticism of local authorities, and intensified political and environmental tensions. Water remains safe for drinking, but authorities warn the public to avoid contact with the river due to ongoing environmental concerns. Huanqiu+2
