Michigan well water service areas

What it costs, and what happens after you send it

What does well water treatment cost in Michigan?

There is no single price, because the contaminant decides the system. Across published national ranges, an under-sink reverse osmosis unit runs $300 to $950 installed, the common whole-house treatment classes run roughly $1,000 to $5,000, and whole-house reverse osmosis is the expensive end at $4,800 to $8,000 (HomeGuide, 2026). Those are national figures, not Michigan averages: no source publishes a Michigan average, so this site does not claim one. Your lab report is what moves a quote inside or past a range, and The water test itself has no single price here: county health departments, EGLE-certified laboratories and state-funded free rounds all price differently. The Michigan cost guide prints the full table by system with every source.

How fast will someone get back to me?

Your request goes to an independent licensed local water treatment contractor, usually within about an hour during the day. That contractor then reviews your lab report and quotes the work in writing on their own schedule.

What work is covered?

Arsenic removal, iron and manganese removal, nitrate removal, PFAS treatment, sulfur odor treatment, water softening, and whole-house well water treatment. See every service.

Only a contractor standing at your well can price your actual water.
