Mammoth Lakes Drinking Water Quality

Consumer Confidence Water Quality Reports

Under the authority of the Safe Drinking Water Act, the EPA requires Mammoth Community Water District to assess local water quality each year and distribute a Consumer Confidence Water Quality Report. At WaterZen, we review these reports and make the information available, in a concise, straightforward, and easy-to-understand way. You can find CCR report on the Mammoth Community Water District website.
