Michigan Environmental Profile
According to the U.S. Environmental Protection Agency's 2023 Toxics Release Inventory, Safe Drinking Water Information System, and Superfund National Priorities List, this is Michigan's (MI) full public environmental-compliance record - toxic releases, drinking-water systems, and Superfund sites in one place.

Michigan consolidates three federal EPA datasets into one statewide environmental profile: 918 Toxics Release Inventory (TRI) facilities reporting under EPCRA Section 313, 1,433 community water systems regulated under the Safe Drinking Water Act, and 89 sites on the Superfund National Priorities List.
TRI facilities in MI have cumulatively disclosed 317.9M lbs of toxic chemical releases, while SDWIS records show 1,000 total violations across the state's regulated water systems, of which 314 systems carry an active health-based violation (MCL exceedance or treatment-technique failure). Activity clusters in counties such as Oakland, Wayne, Kent, which account for the highest combined facility, water-system, and Superfund presence.
Every figure reflects the public regulatory record as filed with the U.S. Environmental Protection Agency and is not weighted for toxicity, geographic footprint, or population exposure. A state can rank high in any individual metric because of industrial history, naturally occurring contaminants in source water, or simply the number of reporting facilities, not because current residents face unsafe conditions. Drill into any county or water system below for the full disclosure record.

TRI data is self-reported annually by facilities that manufacture, process, or use listed toxic chemicals above threshold amounts.
Does Michigan have Superfund sites? ▼
Yes, Michigan has 89 sites on the EPA Superfund National Priorities List (NPL). Superfund sites are contaminated locations identified for long-term cleanup under the EPA Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA).
Is the water safe in Michigan? ▼
Michigan has 1,433 EPA-regulated water systems. 314 water systems have reported health-based violations (MCL exceedances). A past violation does not necessarily mean water is currently unsafe. For current water quality, contact your local water utility. Source: EPA SDWIS.
What environmental data is available for Michigan? ▼
PlainEnviro provides three categories of EPA environmental data for Michigan: Toxic Release Inventory (TRI) data covering 918 industrial facilities, Safe Drinking Water Information System (SDWIS) data for 1,433 water systems, and Superfund National Priorities List (NPL) data for 89 contaminated sites.
How does Michigan compare to other states environmentally? ▼
Michigan has 918 TRI facilities with 317.9M lbs in total releases, 89 Superfund sites, and 1,000 water system violations on record.

About This Data
This page aggregates environmental data from three EPA programs for Michigan: the Toxic Release Inventory (TRI) for industrial chemical releases, the Safe Drinking Water Information System (SDWIS) for water quality, and the Superfund National Priorities List (NPL) for hazardous waste cleanup sites.
PlainEnviro presents this data without advocacy framing. Numbers reflect reported data and may not capture all environmental activity. For specific health or environmental concerns, contact your state environmental agency.
