It’s been a year since a major leak at the Red Hill fuel facility, and the fuel is still sitting in tanks 100 feet above a major drinking water source.

Seventeen people were hospitalized, children experienced seizures and pets died, federal health officials found.

Levels of diesel and oil are getting lower in the aquifer below the Navy’s fuel storage facility, the health department said.

The Navy said there are no indications of “system-wide impacts.”

Experts don’t know where the contamination may be moving. New detection wells could help.

The contamination crisis exposed how little regulators know about how groundwater – and fuel pollution – flow under the Red Hill facility.

The expansion of missile defense on Guam is part of several military projects planned or in progress for the Marianas archipelago.

The budget proposal “signals the administration’s support of our efforts to safely defuel and shut down Red Hill,” U.S. Sen. Brian Schatz said.

The Navy has finished flushing contaminated fluid from all 9,715 homes affected by the fuel leaks.

The decision comes after the state said it will lift Covid-19 restrictions including the Safe Travels program requiring proof of vaccination or a negative test to avoid quarantine.
