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

North Dakota consolidates three federal EPA datasets into one statewide environmental profile: 104 Toxics Release Inventory (TRI) facilities reporting under EPCRA Section 313, 318 community water systems regulated under the Safe Drinking Water Act, and 2 sites on the Superfund National Priorities List.
TRI facilities in ND have cumulatively disclosed 263.3M lbs of toxic chemical releases, while SDWIS records show 169 total violations across the state's regulated water systems, of which 55 systems carry an active health-based violation (MCL exceedance or treatment-technique failure). Activity clusters in counties such as Cass, Stark, Richland, 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.

What environmental data is available for North Dakota? ▼
PlainEnviro provides three categories of EPA environmental data for North Dakota: Toxic Release Inventory (TRI) data covering 104 industrial facilities, Safe Drinking Water Information System (SDWIS) data for 318 water systems, and Superfund National Priorities List (NPL) data for 2 contaminated sites.
How does North Dakota compare to other states environmentally? ▼
North Dakota has 104 TRI facilities with 263.3M lbs in total releases, 2 Superfund sites, and 169 water system violations on record. State-level environmental comparisons depend on many factors including industrial activity, population, and geographic size. Source: EPA TRI, SDWIS, and Superfund NPL databases.
