JOINT BASE ANDREWS, Md. — A massive jet fuel leak totaling approximately 32,000 gallons is under investigation at Joint Base Andrews after it was announced April 13, 2026, that contamination had reached a nearby creek that flows into the Potomac River.
The leak was identified on March 23, when personnel observed a visible fuel sheen and strong petroleum odors in Piscataway Creek within base boundaries. Officials later determined the release occurred over several months between January and March.
Environmental crews quickly began containment efforts, and the affected portion of the base’s fueling system has since been shut down. Officials confirmed the active leak has been stopped, but cleanup and environmental assessments remain ongoing.
State regulators said some of the fuel entered Piscataway Creek, though drinking water systems are not at risk because intake locations are upstream.
The Maryland Department of the Environment said the base failed to promptly report the full extent of the leak as required and cited multiple failures in detection systems over several months. Officials also noted a containment issue in early April during heavy rainfall.
“Contaminating Maryland’s land and water is unacceptable,” said Environment Secretary Serena McIlwain, adding that the state expects answers and accountability.
Cleanup crews have recovered an estimated 10,000 gallons of fuel, while additional mitigation efforts continue, including soil testing and water monitoring.
Joint Base Andrews officials said they are working with federal and state agencies to contain the spill, protect nearby ecosystems, and ensure public safety. The cause of the leak remains under investigation.
Residents are advised to avoid areas of Piscataway Creek where fuel sheen or odors are present and to keep pets away from affected areas.

Must be nice to have no accountability concerns for fuel reserve levels for three months. It’s almost like there’s some magic tax that will keep flowing in regardless of waste.
