By USAG Hawaii, Environmental Division, Directorate of Public Works (DPW)June 2, 2025

WHEELER ARMY AIRFIELD – The Annual Drinking Water Quality Reports for United States Army Garrison Hawaii (USAG Hawaii) water systems are now available for review. These reports now include additional information related to Aliamanu Military Reservation and contaminants in the distribution system during the Hawaii Department of Health (HDOH) Health Advisory. The reports are on the USAG Hawaii Safe Drinking Water Act Program website. (See links below to reports.)

The USAG Hawaii Directorate of Public Works (DPW) operates four (4) water systems – Aliamanu Military Reservation (AMR), Fort Shafter (FS), Schofield Barracks (SB), and Tripler Army Medical Center (TAMC).The Aliamanu report includes both the Aliamanu and Red Hill Housing areas. The Schofield report includes Schofield Barracks, Wheeler Army Airfield, and Helemano Military Reservation.

Since 1999, the US Environmental Protection Agency (EPA) has required public water suppliers to provide annual water quality reports to their water users. These reports are designed to educate the public on the origin of drinking water and provide water quality information for the previous year.

In Hawaii, the primary drinking water supply comes from underground aquifers fed by rainfall. Naturally occurring minerals, radioactive material, and other substances resulting from animal or human activity may be dissolved by the rainfall and percolate into the aquifers. The EPA sets limits on the amount of such contaminants present in drinking water and DPW monitors the drinking water to help ensure that no contaminant level is exceeded.

DPW works hard to provide Army soldiers, families, and employees with the highest water quality possible. DPW encourages residents and workers to look at the report for the installation where they live and/or work.

If you have any questions about the reports or would like to request a hard copy, please contact the DPW Environmental Division at 520-687-2162 or 520-687-2207.
