Wailuku Drinking Water Quality

Consumer Confidence Water Quality Reports

WaterZen Rating

Lead levels in the drinking water of some cities across the United States are too high, potentially creating public-health issues for the people living in those areas.

What about Maui County Water? How much lead is in your drinking water? And how do those levels compare to other cities in the state? We examined data from hundreds of cities across the nation to understand and grade your water quality.

As you can see, Maui County Water received the best-possible grade because the amounts of contaminants found in the water supply were better than the Public Health Goal and most other water providers we've analyzed.
