About Michigan Well Water
This site exists because finding clear, reliable information about well water quality in Michigan is harder than it should be.
Michigan has 2.4 million people on private wells — more than any other state. That's 30% of the population drawing their drinking water from a source that nobody regulates, nobody tests, and nobody monitors. The information well owners need is scattered across government databases, academic papers, and water treatment company sales pages.
We built Michigan Well Water to put the most important information in one place: what contaminants are common in your area, where to get tested, what your results mean, and what your options are if something comes back high.
What This Site Is
- A starting point for understanding your well water
- Community-specific guides based on local geology, real water quality data, and government sources
- Links to certified testing labs, free testing programs, and treatment information
- Plain-language explanations of contaminants, geology, and treatment options
- A public information resource — not a sales funnel
What This Site Is Not
- A substitute for actual water testing (every well is different)
- Professional advice about your specific well or water system
- Affiliated with any government agency, water treatment company, or testing lab
Our Sources
The data on this site comes from government and academic sources, including:
- United States Geological Survey (USGS) — groundwater studies, water quality data
- Michigan Department of Environment, Great Lakes, and Energy (EGLE) — Wellogic database, well construction data, PFAS investigation
- Michigan PFAS Action Response Team (MPART) — contamination site data
- Environmental Protection Agency (EPA) — contaminant standards, private well guidance
- Michigan Department of Health and Human Services — health-based guidance
- Michigan Geological Survey — geological characterization
- County health departments — local testing data, well permit programs
We cite specific sources on each page. If you find an error or have better data, we want to know.
Every well is different. Two wells on the same street can have completely different water quality. The only way to know what's in your water is to test it.
