WashingtonJoint Base Andrews hid a 32,000-gallon fuel spill.
The US base failed a December leak test but told Maryland only in late March, when oil appeared in Piscataway Creek, the Maryland Department of the Environment said.
Volume reaching the Potomac tributary is unknown; Maryland lawmakers are demanding a full disclosure timeline.

THE SOVEREIGN IMMUNITY PROBLEM
Federal facilities are shielded from most state environmental enforcement by sovereign immunity. The 1992 Federal Facility Compliance Act partially waived this for hazardous waste, but reporting timelines and penalties still get filtered through inter-agency negotiation rather than direct state authority.
WHY JET FUEL IS DIFFERENT
JP-8, the military's standard kerosene, contains benzene, toluene, and naphthalene — all carcinogens that dissolve readily in groundwater. Unlike crude, jet fuel has additives (icing inhibitors, corrosion preventives) that resist biodegradation, so contamination plumes persist for decades.
THE PISCATAWAY PATH
Piscataway Creek drains directly into the tidal Potomac roughly 15 miles south of DC, then into Chesapeake Bay — the largest estuary in the United States and a federally protected fishery. A spill at Andrews is not a local creek problem; it enters one of the most regulated watersheds in the country.
THE PRECEDENT
The Pentagon's reporting record is poor. Camp Lejeune contaminated drinking water with benzene and TCE for over thirty years (1953–1987); the Marine Corps knew by the early 1980s but only acknowledged it publicly in 1999. Congress eventually passed a 2012 act granting affected families care — the disclosure gap was measured in decades, not months.
PFAS AND THE BIGGER LIABILITY
Andrews, like every major US airbase, used aqueous film-forming foam (AFFF) for fire training — the source of the PFAS "forever chemicals" contamination found at 700+ DoD sites. The Pentagon's estimated environmental cleanup liability across all bases now exceeds $40 billion. A 32,000-gallon fuel spill is, in this context, a routine entry on a very long ledger.
WHO ENFORCES
The EPA, not the state, is the lead regulator on federal facilities under CERCLA (Superfund). Maryland's Department of the Environment can investigate and publicize, but binding cleanup orders flow through a Federal Facility Agreement negotiated between EPA and DoD — a process that typically takes years, not weeks.
