HONOLULU (AP) - It's still not certain whether 27,000 gallons of jet fuel leaked from an underground Navy tank in Honolulu.
Navy officials say other factors may have caused the discrepancy discovered earlier this year in the tank's levels.
It may take up to a year to complete the investigation into why there was a discrepancy.
The Navy has previously assured state lawmakers that drinking water around the tank is safe.
The Honolulu Star-Advertiser reports Navy officials told Honolulu leaders during a briefing Thursday that one possible reason for the level change could have been water that collected in between the steel fuel tank and a concrete casing that surrounds it.
The Red Hill Underground Fuel Storage Facility held fuel for American planes in World War II.
