Protecting Oahu's Groundwater Aquifer

The Board of Water Supply remains steadfast in our commitment to providing safe, dependable and affordable water for Oahu's needs today and in the future, including taking a strong stance when protecting our groundwater aquifers.

In January 2014, the U.S. Navy reported a 27,000 gallon leak of jet fuel from Tank 5 at its Red Hill Bulk Fuel Storage Facility. This underground storage tank (UST) – along with 19 others like it in the Red Hill area – is able to contain up to 12.5 million gallons of fuel for the U.S. Navy. These tanks are located 100 feet above the Moanalua-Waimalu groundwater aquifer, which the BWS uses to provide water to residents from Moanalua to Hawaii Kai.

To protect the aquifer's long-term ability to provide safe drinking water, the BWS urges the Navy, EPA, and Hawaii DOH to:

  • double line the tanks. If not, then relocate away from the potable water aquifer; meet the same regulatory requirements as all other USTs; and
  • clean up the fuel that is already underneath the tanks to reduce the long-term threat to other wells in the area.

BWS Updates

BWS posts news and updates on its website, including updates from public meetings to materials such as the Administrative Order on Consent (AOC) and Scope of Work (SOW).

Updates on the facility, progress on work related the AOC and/or underground storage tanks may be found on through following online resources:
