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

New Hampshire consolidates three federal EPA datasets into one statewide environmental profile: 145 Toxics Release Inventory (TRI) facilities reporting under EPCRA Section 313, 678 community water systems regulated under the Safe Drinking Water Act, and 22 sites on the Superfund National Priorities List.
TRI facilities in NH have cumulatively disclosed 2.1M lbs of toxic chemical releases, while SDWIS records show 1,402 total violations across the state's regulated water systems, of which 284 systems carry an active health-based violation (MCL exceedance or treatment-technique failure). Activity clusters in counties such as Hillsborough, Rockingham, Carroll, 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.
