MI Well Driller study guide
MI Well Driller · Work through your exam, one topic at a time.
The Michigan Well Driller certification is a state credential for people who construct, develop, repair, and abandon water wells in Michigan. It signals that the holder understands the regulatory framework for well construction and the practical field skills that protect groundwater and keep a well safe to drink from. The MI Well Driller study guide has 8 sections and about 2,672 words.
01Well Siting and Geology
Siting questions blend Michigan's glacial and bedrock geology with the isolation distances that decide whether a location is legal. The exam tests whether you can match an aquifer to a well design and defend a location before the rig moves.
347 words, about 2 min02Well Construction and Casing
Construction questions test the physical choices that keep surface water out of the well: casing depth, casing material, hole diameter, screen selection, and the wellhead finish. Michigan requires a minimum of 25 ft of casing, seated into competent confining material where it occurs shallower than that, and grouted for its full length.
352 words, about 2 min03Grouting and Sealing
Grouting is the seal between casing and borehole wall. It blocks surface water and shallow groundwater from running down the annulus, stabilizes the formation, and prevents cross-connection between aquifers.
315 words, about 2 min04Well Development and Pumping Equipment
Development repairs the formation after drilling and sets the well's long-term performance. Equipment questions test whether you can match pump type, setting depth, and controls to the well's actual yield and drawdown.
339 words, about 2 min05Water Quality and Sampling
Water quality items test whether you can collect a sample that the laboratory will accept and interpret the result correctly for a homeowner. Total coliform with E.
320 words, about 2 min06Well Abandonment and Plugging
An abandoned well is a direct conduit from the surface to the aquifer. Plugging restores the geologic barrier, removes a physical hazard, and prevents mixing of good and poor-quality water.
319 words, about 2 min07Michigan Well Construction Regulations
Michigan regulates water wells under Part 127 of the Public Health Code, administered by the Department of Environment, Great Lakes, and Energy with local health departments issuing permits and reviewing records. Exam items check licensing, permitting, notification, and the paper trail.
338 words, about 2 min08Safety and Jobsite Practices
Safety items on this exam are practical: excavation protection, confined spaces, electrical work, rigging, and dust. They reflect MIOSHA rules that adopt federal construction standards, and they are written as scenarios, not slogans.
