Frequently Asked Questions
What should I test my well water for in Michigan?
EGLE (Michigan Department of Environment, Great Lakes, and Energy) recommends testing annually for coliform bacteria and nitrates at minimum. Given Michigan's well-documented contamination history, also test for: PFAS compounds (a documented concern near former industrial sites statewide, including Wolverine Worldwide's Rogue River contamination and Wurtsmith AFB), lead (especially important given aging housing stock and the Flint water crisis legacy), arsenic, volatile organic compounds (VOCs), iron, manganese, and pH. Check with EGLE or your county health department for contaminants of concern in your specific area.
How often should well water be tested in Michigan?
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 Michigan?
Use a state-certified laboratory. Your county health department, Michigan State University Extension (MSU Extension), or EGLE's environmental monitoring 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 Michigan?
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.
