How many labs test for coliform bacteria in Michigan
172 labs on Michigan's official drinking-water lab list are certified to test for coliform bacteria. All 172 are named for coliform bacteria on the list. 6 of them are marked as taking samples from the public. They are listed first. 7 are located outside Michigan.
The list is published by the Michigan Department of Environment, Great Lakes, and Energy (EGLE) - Laboratory Certification Program. These labs come from list files with 11 different dates; each lab page shows its own. Fetched 2026-11-15 (UTC).
Old list. EGLE's out-of-state, radiological, in-state PFAS, out-of-state PFAS and Cryptosporidium lists are dated 9/8/2025, more than 12 months before we fetched them on Nov 2, 2026, though EGLE's program page still links them. Labs and analytes on them may have changed since. EGLE's chemistry, microbiological and lead and copper lists (3/11/2026) are not affected.

How the Michigan list marks public samples (whole list). Not stated per lab on the lists. Marked yes only for EGLE's own laboratory (its Drinking Water Laboratory page says "Drinking water from public water supplies and private residential wells can be tested") and for the health departments and laboratory that EGLE's Private Residential Water Well Testing page names under "Testing options: These health departments have onsite testing capabilities." EGLE's drinking water testing page tells well owners: "To locate a private laboratory in your area, visit our Laboratory Certification Program page and select the laboratory list you're most interested in."
Before you send a sample, call the lab to confirm it is currently certified for the exact test and method, that it accepts samples from homeowners, and how to collect and ship them. Status can change between list updates.
Why test for coliform bacteria in Michigan
About a third of the 397 domestic wells tested for bacteria in a national USGS study had total coliform. Read our coliform bacteria explainer.
EPA advises private-well owners to test every year for total coliform bacteria, nitrates, total dissolved solids and pH. [1]
Michigan guidance that mentions coliform bacteria:
- EGLE says to contact your local health department for a recommendation on what to test for, since recommendations may differ by area, household and your own concerns. EGLE lists coliforms, nitrites and some metals (like arsenic and lead) as standard concerns for private wells, and notes that U.S. EPA recommends testing all private wells at a minimum for coliform bacteria and nitrate/nitrite. [2]
- Michigan EGLE's Drinking Water Laboratory in Lansing tests drinking water for residents as well as public water supplies and businesses. Tests include total coliform and E. coli bacteria, nitrate and nitrite, metals such as lead, copper and arsenic, and organic chemicals such as PFAS and VOCs. [2]
Prices at Michigan EGLE Drinking Water Laboratory, Preview: Water Testing Fee Schedule, pricing effective Oct 1, 2026 (the lab's first fee increase since 2007), as published when checked on 3 Nov 2026. Private certified labs set their own prices.
| Test | Price |
|---|---|
| Total coliform and E. coli | $23 [3] |
About 2,597,314 people in Michigan used private wells in 2015, by the USGS estimate of people on domestic self-supplied water. [4] Federal limits are written for public water systems, not private wells, so testing is up to the owner.
For tests that depend on your home (farms nearby, old plumbing, a new baby), use the which-tests checklist. When results arrive, check your numbers against EPA's limits. State guidance, county data and every lab: Michigan.
