Frequently Asked Questions
What should I test my well water for in California?
**CDPH** and **CalEPA** recommend testing annually for coliform bacteria and nitrates at minimum. Given regional contamination history in parts of California, also test for **TCE/PCE**, **hexavalent chromium**, **perchlorate**, and **1,2,3-TCP**, plus lead, arsenic, volatile organic compounds (VOCs), iron, manganese, and pH. Check with **CDPH**, **CalEPA**, and your **county Environmental Health** office for contaminants of concern in your area.
How often should well water be tested in California?
Test annually for bacteria and nitrates. Comprehensive testing every 2-3 years is recommended. Test immediately after any flooding event, if you notice changes in taste, odor, or color, or if you receive a notice about contamination in your area from local authorities.
Where can I get my well water tested in California?
Use a state-certified laboratory. Your local board of health, state university cooperative extension office, or environmental watch program can provide sampling kits and recommend certified labs. Some well service companies also partner with certified labs.
How much does well water testing cost in California?
Basic bacterial and nitrate testing costs $75-$150. A standard potable water panel (bacteria, nitrates, pH, iron, manganese, hardness) costs $150-$300. Extended testing for specific contaminants adds $150-$300 per sample. A comprehensive panel including multiple contaminant types costs $400-$700.
