National Mall Fuel Cleanup Efforts Enter Urgent Phase After Underground Storage Tank Leak Discovered
WASHINGTON, D.C. (December 4, 2024, 10:00 AM EST) — A major environmental and logistical operation is underway at the National Mall, where federal authorities have confirmed the discovery of a significant fuel leak from an underground storage tank. What began as a routine inspection by the National Park Service has escalated into an urgent containment and remediation project, drawing multiple government agencies to the heart of the capital.
According to the National Park Service, the leak was detected on Tuesday at approximately 2:00 PM local time near the Reflecting Pool. Officials state a corroded 10,000-gallon diesel storage tank, used to power maintenance vehicles, is the source. An estimated 300 gallons of diesel fuel have seeped into the surrounding soil, with no reports of contamination reaching the nearby Tidal Basin or the Washington Monument grounds.
The Environmental Protection Agency (EPA) has now taken a lead role, deploying specialized Hazmat crews to excavate contaminated soil and install groundwater monitoring wells. A containment boom has been placed along a nearby storm drain as a precautionary measure. Officials emphasize that the public, including the 20,000 daily visitors to the Mall, is not currently at risk due to immediate perimeter fencing and air quality monitoring.
The cause of the corrosion is under investigation, with preliminary reports suggesting a combination of age and soil moisture. The cleanup is expected to take up to two weeks, with portions of the Mall’s western lawn cordoned off. The Department of the Interior has stated that all fuel infrastructure in national parks will undergo mandatory inspections nationwide following this incident. No timeline for the complete restoration of the affected area has been provided.
