Washington Aqueduct deploys water supply protection measures following fuel spill in Fairfax County

Published April 3, 2025

Washington Aqueduct crews have deployed absorbent boom at Potomac River water intakes to protect equipment and regional water supply after a tanker truck crashed into a bridge in McLean, Virginia, early this morning, causing a fuel spill along Difficult Run River.

Absorbent booms are cylindrical barriers designed to contain and absorb oil on the water’s surface. They prevent the spread of oil and facilitate its collection.

A division of the Baltimore District, U.S. Army Corps of Engineers, the Washington Aqueduct operates two intake facilities on the Potomac River at Great Falls and Little Falls, Maryland. Preliminary modeling provided by the Interstate Commission on the Potomac River Basin predicts fuel will reach Little Falls Pump Station on April 3 at 6 p.m. and clear the area by 11 p.m. All operations will come through the Great Falls facility.

No impact to Washington Aqueduct operations, or the region’s water supply, is expected.

A division of the Baltimore District, U.S. Army Corps of Engineers, the Washington Aqueduct is a federally owned and operated public water supply agency that produces an average of 150 million gallons of water per day at two treatment plants located in the District of Columbia.

The Aqueduct collects, purifies and pumps drinking water from a sole source – the Potomac River – for its three wholesale customers: DC Water, Arlington County and Fairfax Water.
