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

South Carolina consolidates three federal EPA datasets into one statewide environmental profile: 660 Toxics Release Inventory (TRI) facilities reporting under EPCRA Section 313, 557 community water systems regulated under the Safe Drinking Water Act, and 34 sites on the Superfund National Priorities List.
TRI facilities in SC have cumulatively disclosed 203.0M lbs of toxic chemical releases, while SDWIS records show 647 total violations across the state's regulated water systems, of which 161 systems carry an active health-based violation (MCL exceedance or treatment-technique failure). Activity clusters in counties such as Kershaw, Greenville, Spartanburg, 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.
