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

Louisiana consolidates three federal EPA datasets into one statewide environmental profile: 467 Toxics Release Inventory (TRI) facilities reporting under EPCRA Section 313, 835 community water systems regulated under the Safe Drinking Water Act, and 29 sites on the Superfund National Priorities List.
TRI facilities in LA have cumulatively disclosed 690.1M lbs of toxic chemical releases, while SDWIS records show 13,618 total violations across the state's regulated water systems, of which 550 systems carry an active health-based violation (MCL exceedance or treatment-technique failure). Activity clusters in counties such as St. Tammany Parish, Caddo Parish, Calcasieu Parish, 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.

Frequently Asked Questions
How many polluting facilities are in Louisiana? ▼
Louisiana has 467 facilities that report to the EPA Toxic Release Inventory (TRI). These facilities have collectively reported 690.1M 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 Louisiana have Superfund sites? ▼
Yes, Louisiana has 29 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 Louisiana? ▼
Louisiana has 835 EPA-regulated water systems. 550 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 Louisiana? ▼
PlainEnviro provides three categories of EPA environmental data for Louisiana: Toxic Release Inventory (TRI) data covering 467 industrial facilities, Safe Drinking Water Information System (SDWIS) data for 835 water systems, and Superfund National Priorities List (NPL) data for 29 contaminated sites.
How does Louisiana compare to other states environmentally? ▼
Louisiana has 467 TRI facilities with 690.1M lbs in total releases, 29 Superfund sites, and 13,618 water system violations on record.
