Drinking Water
Drinking Water
EGLE 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, EGLE 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. EGLE also investigates drinking water well contamination, and oversees remedial activities at sites of groundwater contamination affecting drinking water wells.
MiEHDWIS
The first release of MiEHDWIS, nicknamed Eddy, launched in September 2020 - kicking off a multi-year project to modernize many of Drinking Water and Environmental Health Division's existing permitting, licensing, and compliance information systems into one web-based application. The goal of MiEHDWIS is to streamline communication between Michigan's public drinking water supplies and the Department of Environment, Great Lakes, and Energy (EGLE), increase data transparency and, in future releases, facilitate collaboration between EGLE and local health department staff supporting environmental health programs. Many MiEHDWIS features will eventually be available to regulated entities (campgrounds, public swimming pools, public water supplies, etc.), such as applying for permits or licenses and uploading reports and documentation.
