A complete list of all programs within the Department of Environment, Great Lakes, and Energy (EGLE)
Community involvement and public participation are an essential part of EGLE’s mission, vision, and values.
Resources and information on utilizing RRD's data exchange and the Inventory of Facilities.
An interactive map displaying contaminated sites throughout Michigan regulated under Parts 213, 201, and 211.
This system allows water well drilling and pump installation contractors to submit water well records.
EGLE's interactive calendar is designed to provide timely information on decisions before the Director, proposed settlements of contested cases, administrative rules promulgation, public hearings, meetings and comment deadlines, and environmental conferences, workshops and training programs.
The Michigan Freedom of Information Act (FOIA) provides all persons (except persons incarcerated in correctional facilities) with access to public records of public bodies. Requests to inspect or receive public records from EGLE must be in writing and describe the requested records with enough detail to enable the department to identify and locate the requested records. Some records are exempt from disclosure under the FOIA or another statute and thus will not be provided. A fee may be charged to process your request. Please note that many records are available that do not require a formal FOIA request.

Although groundwater is typically a safe source of drinking water and actual events of drinking water contamination are rare, contaminants can enter the drinking water supply if any of the protective barriers are breeched. Heightened public awareness, concern for public health, and advancements of technology are factors behind legislative action to set national standards regarding the levels of contaminants in drinking water.
Water quality monitoring has an important role in identifying breeches in the system that may threaten safe and aesthetically pleasing water, however, it is important to understand that a water sample is a very small part of the total water supply and not a protective barrier.
There are potentially thousands of different contaminants that could find their way into drinking water systems that may be harmful to health. It is impractical to attempt to test for all possible contaminants. Priorities for testing are determined, in general, based on national occurrence data, health effects and technology.
Sampling requirements are tied to population served, source of water, and sampling history results of the sanitary survey.
Systems that serve 1,000 or fewer persons per day must sample quarterly unless on a different frequency as prescribed by the local health department.
Systems that serve 1,001 or more persons per day must sample monthly. The number of samples per month is determined by the population served.
Annual sampling required for all systems unless results indicate a heightened level and increased monitoring in prescribed by the local health department.
Each system is evaluated and put on a monitoring cycle prescribed by the local health department.
The Remediation and Redevelopment Division (RRD) of EGLE certifies laboratories to ensure that proper methods and quality control are used in the testing of drinking water samples.
