What this shows The chart shows reported TRI release totals only. Compare two states to place those totals alongside water-system and Superfund records.

According to the U.S. Environmental Protection Agency, every figure on this page is computed from PlainEnviro's database of more than 25,000 TRI-reporting facilities, 49,190 public water systems and 1,839 Superfund National Priorities List sites; toxic-release totals cover the 2023 TRI reporting year, while drinking-water violation records run through 2025. No state is scored, rated or recommended here, the two columns simply place each state's reported figures side by side; see our methodology for full source citations and refresh cadence.
