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

Washington consolidates three federal EPA datasets into one statewide environmental profile: 367 Toxics Release Inventory (TRI) facilities reporting under EPCRA Section 313, 2,397 community water systems regulated under the Safe Drinking Water Act, and 69 sites on the Superfund National Priorities List.
TRI facilities in WA have cumulatively disclosed 92.7M lbs of toxic chemical releases, while SDWIS records show 2,705 total violations across the state's regulated water systems, of which 295 systems carry an active health-based violation (MCL exceedance or treatment-technique failure). Activity clusters in counties such as Kitsap, Pierce, King, 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 Washington? ▼
Washington has 367 facilities that report to the EPA Toxic Release Inventory (TRI). These facilities have collectively reported 92.7M 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 Washington have Superfund sites? ▼
Yes, Washington has 69 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 Washington? ▼
Washington has 2,397 EPA-regulated water systems. 295 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.
