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 Massachusetts's (MA) full public environmental-compliance record - toxic releases, drinking-water systems, and Superfund sites in one place.
Violation/site counts mapped to the EPA statutes this portal tracks
Clean Water Act, NPDES (water-system health violations)
236 records
RCRA Subtitle C (Superfund-site proxy)
41 records
What this shows Counts are mapped to statute as a structural proxy and reflect reported activity, not toxicity-weighted or population-adjusted risk. Clean Air Act (Title V) permit data is not currently ingested by this portal, so air-permit compliance is not shown here.

TRI cumulative disclosure
Massachusetts consolidates three federal EPA datasets into one statewide environmental profile: 450 Toxics Release Inventory (TRI) facilities reporting under EPCRA Section 313, 564 community water systems regulated under the Safe Drinking Water Act, and 41 sites on the Superfund National Priorities List.
TRI facilities in MA have cumulatively disclosed 18.3M lbs of toxic chemical releases, while SDWIS records show 1,106 total violations across the state's regulated water systems, of which 236 systems carry an active health-based violation (MCL exceedance or treatment-technique failure). Activity clusters in counties such as Worcester, Middlesex, Essex, 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.

This page aggregates environmental data from three EPA programs for Massachusetts: 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.
What to do with Massachusetts's data
Use this state profile as a starting point, then drill into the specific dataset that matters to you.
Reported data reflects what facilities and agencies disclose to the EPA; it is not a complete measure of environmental risk or a substitute for local guidance.
Read our methodology - how this data is sourced, computed, and verified.
According to the U.S. Environmental Protection Agency, this state profile is drawn from PlainEnviro's database of more than 25,000 EPA-tracked facilities, the Safe Drinking Water Information System, and the Superfund National Priorities List, compiled since federal reporting began under the Emergency Planning and Community Right-to-Know Act in October 1986; see our methodology for full source citations and refresh cadence.
Every figure on PlainEnviro is rendered directly from EPA environmental compliance data, no number is typed in by an editor. State environmental figures are computed directly from EPA data.
