District of Columbia consolidates three federal EPA datasets into one statewide environmental profile: 12 Toxics Release Inventory (TRI) facilityies reporting under EPCRA Section 313, 12 community water systems regulated under the Safe Drinking Water Act, and 1 site on the Superfund National Priorities List.
TRI facilities in DC have cumulatively disclosed 92.2K lbs of toxic chemical releases, while SDWIS records show 51 total violations across the state's regulated water systems — of which 9 systems carry an active health-based violation (MCL exceedance or treatment-technique failure). Activity clusters in counties such as District Of Columbia, 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.
