North Carolina Environmental Profile

North Carolina consolidates three federal EPA datasets into one statewide environmental profile: 924 Toxics Release Inventory (TRI) facilities reporting under EPCRA Section 313, 1,965 community water systems regulated under the Safe Drinking Water Act, and 42 sites on the Superfund National Priorities List.

TRI facilities in NC have cumulatively disclosed 284.5M lbs of toxic chemical releases, while SDWIS records show 2,788 total violations across the state's regulated water systems, of which 656 systems carry an active health-based violation (MCL exceedance or treatment-technique failure). Activity clusters in counties such as Wake, Mecklenburg, Guilford, 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.
