Maui Water Reports

Maui's tap water meets legal standards, but legal and healthy aren't the same thing. These reports show you what's in the water where you live, drawn from the Environmental Working Group's Tap Water Database and the County of Maui's annual water quality reports, and compared to health guidelines, not just legal limits.

Find your region below. Each report is reviewed and updated twice a year.
