Treatment Options and Costs
What you'll actually pay for common treatment systems in Michigan:
| System | Equipment Cost | Installation | Notes |
|---|---|---|---|
| Water softener | $1,000-$2,500 | Ion exchange. Addresses hardness only. Standard equipment for most Michigan wells. | |
| Iron filter (oxidation) | $800-$2,500 | Birm, greensand, or air injection. Often combined with softener. | |
| Point-of-use RO (kitchen sink) | $239-$600 | $150-$700 | Treats one tap. Effective for arsenic, PFAS, nitrates, and most contaminants. |
| Whole-house RO | $4,500-$20,000+ | Treats all water. High maintenance. For severe contamination. | |
| UV disinfection | $350-$1,500 | $200-$600 | Whole-house bacteria treatment. Annual bulb replacement. |
| GAC filter (PFAS) | $1,000-$3,000 | Granular activated carbon. Good for PFAS, some VOCs. Ongoing filter replacement. | |
| Aeration system (H2S) | $1,500-$3,500 | Removes hydrogen sulfide (rotten egg smell). Common in NE Michigan. | |
Always test before you buy. Know what's in your water, at what concentrations, and then match the treatment to the problem. A salesperson who recommends a system without your test results is not working in your interest.
Government Resources
- Michigan EGLE Department of Environment, Great Lakes, and Energy. Oversees well construction, water quality, and maintains the Wellogic well database. Start here for state-level resources.
- Michigan PFAS Action Response Team Coordinates statewide PFAS investigation and response. Free testing near known sites. Call 800-662-9278.
- Your County Health Department Environmental health divisions handle well permits, testing guidance, and local water quality concerns. Find yours at michigan.gov/mdhhs.
- Michigan DHHS Department of Health and Human Services. Provides health-based guidance on well water contaminants, including PFAS exposure.
- USDA Rural Development - Michigan Grants and loans for rural water systems. Individual well owners may qualify through community programs.
- EPA Private Well Resources Federal guidance for private well owners, testing recommendations, and contaminant fact sheets.
Well Construction and Maintenance
- Michigan Well Driller Program All well drillers in Michigan must be licensed. Well construction records are filed with EGLE and available through the Wellogic database. If you need a new well or repairs, use only licensed drillers.
- Well Maintenance Basics Inspect your wellhead annually. Ensure the cap is secure, no standing water around the casing, and a minimum 50-foot separation from septic systems. If your well is over 20 years old, consider a well inspection by a licensed driller.
