About 3,003 households in Houghton County, 21% of the county, rely on a private well. Nobody tests that water unless the owner does.
Houghton County has an estimated 3,003 households on private wells, 21% of the county. If you are one of them, testing, treatment and repairs are yours to arrange.
Michigan’s well construction code applies in Houghton County, which means a permit from the local health department, an inspection, and a bacteria sample before use. Selling a home with a well may trigger a county point-of-sale program; the health department can confirm.
Michigan requires new wells to be tested at installation under the well construction code (Part 127 of the Public Health Code). Local health departments issue the permit and require the sample.
No statewide requirement, but several counties run time-of-sale or point-of-sale well and septic evaluation programs. Check the county page.
EGLE recommends testing for coliform bacteria, nitrate and nitrite, fluoride, chloride, sulfate, sodium, hardness, and metals including arsenic, lead, iron, manganese, copper, uranium and others. Bacteria and nitrate yearly; a full chemistry panel every few years or when water changes.
Eight county health departments run their own onsite labs (Washtenaw, Oakland, Kalamazoo, Saginaw, Luce, Mackinac, Alger, Schoolcraft). Residents elsewhere can order a mail-in test through the EGLE Drinking Water Laboratory.
