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

Pennsylvania consolidates three federal EPA datasets into one statewide environmental profile: 1,241 Toxics Release Inventory (TRI) facilities reporting under EPCRA Section 313, 1,787 community water systems regulated under the Safe Drinking Water Act, and 127 sites on the Superfund National Priorities List.
TRI facilities in PA have cumulatively disclosed 253.6M lbs of toxic chemical releases, while SDWIS records show 5,198 total violations across the state's regulated water systems, of which 772 systems carry an active health-based violation (MCL exceedance or treatment-technique failure). Activity clusters in counties such as Lancaster, Berks, Luzerne, 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 Pennsylvania? ▼
Pennsylvania has 1,241 facilities that report to the EPA Toxic Release Inventory (TRI). These facilities have collectively reported 253.6M 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 Pennsylvania have Superfund sites? ▼
Yes, Pennsylvania has 127 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 Pennsylvania? ▼
Pennsylvania has 1,787 EPA-regulated water systems. 772 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.
