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.

Radon in the ground can dissolve into groundwater. When this groundwater is brought into a building, the dissolved gas is released from the water. As a rule of thumb for homes with private wells, if the well water contained 10,000 picocuries per liter (pCi/L) of radon, the amount of radon entering the home from normal water use would be 1 pCi/L of radon. Besides, there aren't any standards or recommended action levels for the amount of radon allowed in public drinking water supplies.
U.S. Environmental Protection Agency (USEPA) publications recommend testing for radon in water for all homes with private wells that have found elevated radon concentrations in air (levels greater than 4 pCi/L). However, elevated indoor radon concentrations are most often caused by radon in soil gas, not radon in household water. In fact, only in a few areas of the United States would radon from well water be expected to make a significant contribution to radon in air concentrations, and Michigan is not among those areas. Notably too, much of the health risk from radon is associated with inhalation, not ingestion, and drinking or cooking with water that contains some radon is not known to pose a significant health risk.
The Michigan Department of Environment, Great Lakes, and Energy recommends that elevated indoor radon levels be treated first as a soil gas problem, using conventional radon reduction techniques to lower those levels. Radon in water testing need not be routinely conducted and would be recommended only if the conventional techniques are not successful. Then, the homeowner may wish to test the water to determine whether it is contributing to the radon in air levels. However, it should be noted that, as of this time, there are no lists of laboratories certified to measure radon in water.
For more information on radon in water and public water standards, contact the USEPA Drinking Water Hotline (800-426-4791) or see the National Academy of Sciences, Risk Assessment of Radon in Drinking Water. Additional resource information can be found at Kansas State University's National Radon Program Services website.
