Best Well Water Testing in Belleville, IL

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.

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.
