About 268 households in Wayne County, 0% of the county, rely on a private well. Nobody tests that water unless the owner does.
Most of Wayne County is on public water, but an estimated 268 households still rely on a private well. This page covers the rules, labs and licensed contractors that serve them.
Michigan’s well construction code applies in Wayne 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.
