Drinking Water

• DEQ Drinking Water Programs

  The DEQ has primary enforcement authority in Michigan for the Federal Safe Drinking Water Act under the legislative authority of the Michigan Safe Drinking Water Act. As such, the DEQ has regulatory oversight for all public water supplies, including approximately 1,400 community water supplies and 10,000 noncommunity water supplies. The program regulates the water well drilling industry. Michigan has nearly (1.12 million) households served by private wells, with approximately 15,000 domestic wells drilled each year. The DEQ also investigates drinking water well contamination, and oversees remedial activities at sites of groundwater contamination affecting drinking water wells.
