Water Treatment in Michigan

In Michigan, public water systems are regulated by the Michigan Department of Environment, Great Lakes, and Energy (EGLE) under the federal Safe Drinking Water Act, and utilities must publish an annual water-quality report. Groundwater in much of Michigan is hard, and iron and a hydrogen-sulfide (rotten-egg) odor are common private-well complaints. Private wells are not covered by those federal rules, so the EPA and CDC recommend testing your own water at least once a year. Match a filter, softener, or reverse-osmosis system to what your test shows.
