We are fortunate that the American River is a good, clean source for our local water supplies. Your drinking water is tested thousands of tests over the course of the year to ensure a safe supply at all times.
Testing is conducted on a daily, weekly, quarterly and annual basis.
Water agency laboratories or state-certified water quality laboratories conduct a variety of tests on your drinking water. The charts near the bottom of this web page summarize the annual water quality report. A printed copy is mailed to you from our water supplier, the San Juan Water District. The first chart summarizes testing for Primary Drinking Water Standards compliance. Your water supply meets or surpasses all safety standards.
