Minnesota 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 Minnesota's (MN) full public environmental-compliance record - toxic releases, drinking-water systems, and Superfund sites in one place.

Minnesota consolidates three federal EPA datasets into one statewide environmental profile: 592 Toxics Release Inventory (TRI) facilities reporting under EPCRA Section 313, 993 community water systems regulated under the Safe Drinking Water Act, and 49 sites on the Superfund National Priorities List.
TRI facilities in MN have cumulatively disclosed 113.1M lbs of toxic chemical releases, while SDWIS records show 845 total violations across the state's regulated water systems, of which 115 systems carry an active health-based violation (MCL exceedance or treatment-technique failure). Activity clusters in counties such as Hennepin, Anoka, Ramsey, 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.

Frequently Asked Questions
How many polluting facilities are in Minnesota? ▼
Minnesota has 592 facilities that report to the EPA Toxic Release Inventory (TRI). These facilities have collectively reported 113.1M lbs in total toxic chemical releases. TRI data is self-reported annually by facilities that manufacture, process, or use listed toxic chemicals above threshold amounts.
Does Minnesota have Superfund sites? ▼
Yes, Minnesota has 49 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 Minnesota? ▼
Minnesota has 993 EPA-regulated water systems. 115 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 Minnesota? ▼
PlainEnviro provides three categories of EPA environmental data for Minnesota: Toxic Release Inventory (TRI) data covering 592 industrial facilities, Safe Drinking Water Information System (SDWIS) data for 993 water systems, and Superfund National Priorities List (NPL) data for 49 contaminated sites.
How does Minnesota compare to other states environmentally? ▼
Minnesota has 592 TRI facilities with 113.1M lbs in total releases, 49 Superfund sites, and 845 water system violations on record. State-level environmental comparisons depend on many factors including industrial activity, population, and geographic size. Source: EPA TRI, SDWIS, and Superfund NPL databases.
