High levels of diesel found at Oahu well


HONOLULU — The state Department of Health says high levels of diesel have been detected at a Tripler Army Medical Center monitoring well.

State Deputy Health Director Gary Gill told a Honolulu City Council committee the Navy told him about the contaminant last week.

The Honolulu Star-Advertiser reports preliminary findings showed 790 and 660 micrograms per liter. That’s above the Health Department’s “environmental action level” of 100 micrograms.

The Navy in January discovered an underground storage tank at nearby Red Hill leaked up to 27,000 gallons of jet fuel. It’s not clear whether the incidents are related.

Board of Water Supply manager Ernest Lau says the agency’s five wells nearby show no sign of contamination. Wells in the area supply water to about one-quarter of the Board of Water Supply system.
