MI Water Operator study guide
MI Water Operator · Work through your exam, one topic at a time.
Michigan Drinking Water Operator Certification is the state credential that allows an individual to serve as the responsible operator of a public water supply in Michigan. The program sits within the Michigan Department of Environment, Great Lakes, and Energy (EGLE), under the Drinking Water and Environmental Health division, and EGLE maintains separate pages for drinking water operator certification and for training and exams. The credential is intended for people who operate or supervise treatment plants, distribution systems, and source-water/well facilities - both new entrants building a career and experienced staff who need certification at a higher classification. Exams are multiple choice and are organized around five practice areas: water treatment, water distribution, source water and well operations, regulations and compliance reporting, and safety, security, and emergency response.
