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

Sites with at least one open violation 26.1%
Texas consolidates three federal EPA datasets into one statewide environmental profile: 2,342 Toxics Release Inventory (TRI) facilities reporting under EPCRA Section 313, 4,587 community water systems regulated under the Safe Drinking Water Act, and 70 sites on the Superfund National Priorities List.
TRI facilities in TX have cumulatively disclosed 1088.6M lbs of toxic chemical releases, while SDWIS records show 33,822 total violations across the state's regulated water systems, of which 1,807 systems carry an active health-based violation (MCL exceedance or treatment-technique failure). Activity clusters in counties such as Harris, Travis, Montgomery, 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 Texas? ▼
Texas has 2,342 facilities that report to the EPA Toxic Release Inventory (TRI). These facilities have collectively reported 1088.6M 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 Texas have Superfund sites? ▼
Yes, Texas has 70 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 Texas? ▼
Texas has 4,587 EPA-regulated water systems. 1,807 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.
What environmental data is available for Texas? ▼
PlainEnviro provides three categories of EPA environmental data for Texas: Toxic Release Inventory (TRI) data covering 2,342 industrial facilities, Safe Drinking Water Information System (SDWIS) data for 4,587 water systems, and Superfund National Priorities List (NPL) data for 70 contaminated sites.
How does Texas compare to other states environmentally? ▼
Texas has 2,342 TRI facilities with 1088.6M lbs in total releases, 70 Superfund sites, and 33,822 water system violations on record.
