The Red Hill Bulk Fuel Storage Facility in Honolulu may have leaked as much as 2 million gallons of fuel into the ground since it was built during World War II, according to a new report from state and local officials, Stars and Stripes reported. That is far more than what had previously been estimated.

DOD permanently closed the facility as it cleans up from the 2021 spill that contaminated water for many families on and near Joint Base Pearl Harbor-Hickam.

“The Navy remains committed to the safe and permanent closure of the Red Hill Bulk Fuel Storage Facility and long-term environmental remediation of the site,” the Navy said Tuesday in a statement. “Partnership and collaboration are key to the success of these endeavors, and we share the same goals as the people of Hawaii: protect the environment, the water and the community.”
