Frequently Asked Questions

What should I test my well water for in Illinois?

The Illinois Department of Public Health (IDPH) and Illinois EPA (IEPA) recommend testing annually for coliform bacteria and nitrates at minimum. Given Illinois-specific contamination history, also test for: radium (naturally occurring in deep Cambrian-Ordovician sandstone aquifers across northern Illinois), nitrates and atrazine from agricultural runoff, lead, arsenic, volatile organic compounds (VOCs), iron, manganese, and pH. Check with your state environmental agency for contaminants of concern in your region.

How often should well water be tested in Illinois?

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 Illinois?

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 Illinois?

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.
