In Hawaii, the primary drinking water supply comes from underground aquifers fed by rain-fall filtered down through the ground and rock. As required by federal and state law, water samples for various contaminants are taken throughout each year at the water source and at various points within U.S. Army Garrison Hawaii's water distribution systems.
If you live on one of the installations, chlorine and fluoride are added to the water, as required by Army standards, before it is piped into the distribution systems and enters your home. Please note if you reside off post, fluoride is not added to your drinking water as it not a requirement of the State of Hawaii Department of Health.
Sampling results are summarized annually in Consumer Confidence Reports (see below) and must be distributed by July 1 each year.
Aside from reporting the quality of the drinking water, the Consumer Confidence Reports also contain details about your water system including information about the origin of the water and the source of potential water quality problems.
Consumer Confidence Reports
The Safe Drinking Water Act requires all community water systems to provide an annual Consumer Confidence Report to their customers. Consumer Confidence Reports are designed to educate the public on the origin of the water, the source of potential problems, and the steps used to ensure that the water is safe to drink.
U.S. Army Garrison Hawaii provides these reports as a service to the community in conjunction with this requirement.
