Southwest Michigan's PFAS chapter
Well water treatment in Kalamazoo County, Michigan
In July 2018, a round of sampling in Kalamazoo County rewrote how Michigan responds to PFAS in drinking water. The small city of Parchment, just north of Kalamazoo, became the state's emergency template, and the investigation that followed did not stop at the municipal meter: private wells around the system were drawn into the sampling. Well owners across the rest of the county live with the quieter statewide constants, iron, manganese, and hardness. Treatment gets sized from certified lab results, and the quote is free.
The Parchment emergency, dated
The numbers are on the record with MPART, the Michigan PFAS Action Response Team. Sampling in July 2018 found PFAS totaling about 1,587 ppt in the Parchment municipal water system. The response set the pattern the state still follows: an emergency declaration, a do-not-drink advisory, and a switch of the system to Kalamazoo city water.
The part that matters on this page is what happened next. Investigators sampled beyond the city system, into the private wells around Parchment and Cooper Township, because a plume does not respect a service boundary. If your address sits near the mapped investigation area, start with the MPART pages and your health department before buying anything: state-run testing and remedies may already cover you. The full three-site plume narrative, Belmont, Parchment, and Oscoda, lives in the PFAS in Michigan well water guide, and the technology walk is on the PFAS treatment page.
What the rest of the county's reports fail on
Most Kalamazoo County well reports never mention PFAS. They fail on the lines that fail almost everywhere in Michigan groundwater: iron and manganese above the EPA secondary standards, staining fixtures and laundry, and hardness that scales water heaters. The fixes are routine, covered on the iron and manganese and water softening pages, with sourced price ranges in the Michigan cost guide.
One honest note on arsenic: Kalamazoo County was not among the nine counties in the USGS arsenic study that mapped the Marshall Sandstone corridor, so this site quotes no arsenic median for it. Arsenic still turns up well by well across Michigan, which is a reason to test, not to worry. A report carrying more than one finding, PFAS plus the everyday lines included, belongs in the whole-house treatment conversation, and every result band is explained in Your Michigan Well Test, Explained.
Testing a well in Kalamazoo County
The county keeps this local. Environmental Health at Kalamazoo County Health and Community Services, 311 E. Alcott St. in Kalamazoo, (269) 373-5210, runs a groundwater protection program and offers fee-based testing for nitrate, coliform bacteria, and E. coli, the same two lines EGLE recommends every well owner check annually.
PFAS analysis needs a laboratory certified for it, so route PFAS questions through MPART and an EGLE-certified drinking water laboratory. Metals and hardness join the panel when equipment is being sized, and the free well water testing guide tracks state-funded rounds when they open.

Check the credentials yourself
Verify your water treatment contractor
You never have to take anyone's word for their credentials, including the contractor who quotes your job. Michigan keeps public records for the people and independent listings for the equipment. Four places to look before you sign:
EGLE contractor registration
Michigan registers water well drilling contractors and pump installation contractors through EGLE under Part 127 of the Public Health Code, renewed every year. If a project touches your well or its pump, ask for the registration number and check it with EGLE.
EGLE water well contractor registrationNSF-certified equipment
Certification to an NSF/ANSI standard means an independent lab verified the claim on the label: NSF/ANSI 44 for cation-exchange softeners, 53 for named health contaminants, 58 for reverse osmosis systems. Ask which standard a proposed unit carries, then look the model up in NSF listings.
NSF standards for water treatment systemsYour county health department
County health departments issue well permits, keep well records, and run private well sampling programs. They are the local authority on your well, and MDHHS publishes statewide guidance for well owners. Neither works for any contractor, which is exactly why their answers are useful.
MDHHS well water guidanceEGLE-certified drinking water labs
EGLE certifies the drinking water laboratories whose results Michigan health departments accept. Any treatment quote should be sized from a certified lab report, and EGLE recommends testing for coliform bacteria and nitrate every year.
How to get your water tested, EGLEThree questions worth asking any water treatment contractor
- 1. Are you registered with EGLE for any well or pump work this project involves, and what is the registration number?
- 2. Which NSF/ANSI standard is this equipment certified to, and for which specific contaminant claims?
- 3. Will you size the system from a certified lab result, and will the written quote list the water numbers it was designed around?
A referral through this site is not an endorsement, and these checks work on anyone. A good contractor answers all three without hesitation.
What it costs, and what happens after you send it
- What does well water treatment cost in Kalamazoo County?
- 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.
Kalamazoo County well water questions
Was my Kalamazoo County well affected by the Parchment PFAS emergency?
Only if your well sits near the documented investigation area around Parchment and Cooper Township, north of the city of Kalamazoo. The July 2018 emergency began in the Parchment municipal system, and the sampling that followed reached private wells outside that system, per MPART. Check the MPART Parchment site pages first: if your address falls inside the mapped area, state-run testing and remedies may already cover it. A well elsewhere in the county is a lower-probability case, and a certified lab test is how you replace probability with a number.
Where do I get well water tested in Kalamazoo County?
Through Environmental Health at Kalamazoo County Health and Community Services, 311 E. Alcott St. in Kalamazoo, (269) 373-5210, which runs a groundwater protection program and offers fee-based testing for nitrate, coliform bacteria, and E. coli. For PFAS, use a laboratory certified for PFAS drinking water analysis via the EGLE testing resources, since those methods run at parts-per-trillion sensitivity. EGLE guidance is coliform and nitrate annually, plus metals and hardness when treatment is being sized.
Does Kalamazoo County have the arsenic problem the Thumb counties have?
It was not part of the USGS nine-county arsenic study that mapped the Marshall Sandstone corridor, so this site quotes no county arsenic median for it. That does not promise a clean report: arsenic shows up well by well across Michigan, and a certified test is the only way to know yours. The everyday failures here are the statewide ones, iron, manganese, and hardness, and the defining local story is PFAS rather than bedrock arsenic.
Who installs well water treatment in Kalamazoo County?
An independent licensed local contractor who works the Kalamazoo area. That contractor sizes equipment from your certified lab result and quotes it in writing, and your agreement is directly with them.
