Water Quality Report - 2023 Publication
Annual Water Quality Report for County of Maui Water Systems
Each year, the Maui Department of Water Supply provides its customers with an Annual Water Quality Report to let them know that our water meets all established federal and state drinking water standards. We encourage you to review this report as it provides details about the source and quality of the drinking water delivered to your community in 2022. The Maui Department of Water Supply has been treating and testing the quality of its water since the Department was organized in 1949. To ensure the safety of your water, hundreds of tests are run annually to determine the presence of potential contaminants such as bacteria, pesticides and herbicides, asbestos, lead, copper, petroleum products, and by-products of industrial and water treatment processes.
