A report released by the Honolulu Board of Water supply found no contaminants in its Halawa Shaft. Samples were collected on Dec. 1.
“What we found in Halawa shaft, in that particular report, is consistent with what we have been detecting over the last eight years — that there is no evidence of fuel contamination nor JP-5, JP-8 in the water as well as any of the total petroleum hydrocarbons gasoline, diesel, or oil fractions" said Erwin Kawata, the Board of Water Supply’s water quality program administrator.

They also did not detect other fuel components or hydrocarbons, nor did they find naphthalene. The report shows no heavy metals such as lead and mercury were detected.
The Board of Water Supply will also monitor pump stations at Halawa Well, Aiea Well, Aiea Gulch and Moanalua Well on a weekly basis. Samples were collected last week and have been sent to a lab.
Results will be posted on their website.
The Halawa shaft, which supplies about 20% of the water to urban Honolulu, was shut down on Dec. 2 after petroleum was found in a Navy well that pumps from the same aquifer.
