Drinking water standards are established by the U.S. Environmental Protection Agency and California State Department of Health Services. In order to be called safe, water supplies must stay within EPA and State maximums when measured for certain contaminants.

The water Supply Analysis establishes whether or not there is a detectable presence of a contaminant in our water supply.

The following terms and abbreviations define words used in our Source Analysis Table.

You can review the groundwater, surface water and distribution system data by comparing the columns on the right, which show our water’s average amount and range of detected contaminants.

These test results reflect all of our groundwater wells and mountain stream sources.
