Most drinking water in Oahu is provided to consumers by public water providers. As directed by the Safe Drinking Water Act, drinking water is tested at least annually by water providers for a wide variety of contaminants.

More information on drinking water safety and testing can be found on the Hawaii Department of Health’s Safe Drinking Water Branch Exit website.
