The United States Environmental Protection Agency (EPA) requires drinking water suppliers to provide an annual water quality report / Consumer Confidence Report (CCR) to their customers. This report provides consumers information about their drinking water, including the water sources, contaminants detected in finished water, health effects of contaminants when violations occur, likely sources of detected contaminants, and availability of source water assessments. By understanding their water supplies, customers, especially those with special health needs, can make informed decisions regarding their use of drinking water. Shown below are links for the CCRs for each of the Commander, Navy Region Japan installations.
