In Tuscola County, roughly 72% of households, about 15,512 homes, draw their water from a private well. Nobody tests it, treats it or inspects it unless the owner does.
In Tuscola County the local health department issues the well permit, inspects construction and requires a water sample before a new well goes into service, as Michigan’s well code requires. Ask the same office whether the county runs a time-of-sale evaluation program, since several Michigan counties do.
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.
The nearest certified lab is Saginaw County Health Department Laboratory in Saginaw, about 28 miles from the county center, and it accepts samples from homeowners. There are 2 more within 40 miles, listed below with what each tests for.
