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

Oregon consolidates three federal EPA datasets into one statewide environmental profile: 335 Toxics Release Inventory (TRI) facilities reporting under EPCRA Section 313, 938 community water systems regulated under the Safe Drinking Water Act, and 21 sites on the Superfund National Priorities List.
TRI facilities in OR have cumulatively disclosed 97.8M lbs of toxic chemical releases, while SDWIS records show 2,578 total violations across the state's regulated water systems, of which 390 systems carry an active health-based violation (MCL exceedance or treatment-technique failure). Activity clusters in counties such as Clackamas, Multnomah, Lane, 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.

About This Data
This page aggregates environmental data from three EPA programs for Oregon: the Toxic Release Inventory (TRI) for industrial chemical releases, the Safe Drinking Water Information System (SDWIS) for water quality, and the Superfund National Priorities List (NPL) for hazardous waste cleanup sites.
PlainEnviro presents this data without advocacy framing. Numbers reflect reported data and may not capture all environmental activity. For specific health or environmental concerns, contact your state environmental agency.
