An interactive map displaying contaminated sites throughout Michigan regulated under Parts 213, 201, and 211.
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.

In October 2019, the Michigan Department of Environment, Great Lakes, and Energy (EGLE) submitted draft PFAS drinking water rules to Governor Whitmer. The final rules took effect of August 3, 2020. These rules amend current drinking water rules by establishing maximum contaminant levels (MCLs) and sampling requirements for seven PFAS compounds. The purpose of the rules is to increase public health protection through testing and reducing exposure to PFAS in drinking water. All community water supplies and nontransient noncommunity water supplies are subject to the PFAS rules.
In this video, public water supplies will learn how to properly take a sample for PFAS analysis by the State of Michigan Drinking Water Laboratory. Sampling for PFAS is very important and it is critical that the sampling is done properly to ensure accurate results.
PFAS sampling is different from other types of sampling because PFAS are present in many things we use in our everyday life, such as water-resistant and stain-resistant products. PFAS can also be present in:
Since PFAS are analyzed in such small quantities - parts per trillion - even the smallest cross-contamination could contribute to a false positive sample.
To learn more about which products contain PFAS and which do not, review the General PFAS Sampling Guidance document. Then use the media-specific guidance document for the specific type of sampling you are interested in.
This document is intended for water supplies to use when collecting PFAS samples. Most laboratories will provide their own sample collection instructions. This guidance document may be used in conjunction with any sample collection instructions provided by the laboratory. This document does not supersede the laboratory’s sampling instructions.
