National data study
Data from the EPA Toxics Release Inventory, Safe Drinking Water Information System, and Superfund National Priorities List, current in PlainEnviro through 2026-08-01, produce this searchable national study. It covers 25,902 TRI facilities, 49,190 public water systems, and 1,839 Superfund sites. Each ranking is an original database aggregation with the limits of its measure stated beside it.
Both files contain the seven findings on this page, their source programs, limitations, and the 2026-08-01 data vintage. They are a citable summary, not a bulk export of the entity corpus.
These are corpus counts, not estimates of environmental quality. They describe how much federal source material is represented in this edition of the database.
Each sentence below is computed from the current database and can be cited independently. The figures are descriptive counts and totals, not safety or health-risk judgments.
TRI release volume
PlainEnviro's 2023 TRI aggregation records 3.9 billion lb for Alaska. Total pounds combine release pathways and chemicals with very different toxicities, so this is a volume measure, not a health-risk score.
View all states by release volumeReporting footprint
The database records 2,342 TRI-reporting facilities for Texas. Facility counts reflect industrial structure and federal reporting thresholds; they do not measure the amount or toxicity of releases.

The current SDWIS aggregation contains 35,614 reported violation records for Texas. This raw total is not normalized by population, system count, monitoring activity, duration, or health basis and cannot rank water safety.

PlainEnviro records 153 NPL sites for New Jersey in this source edition. A site count describes the federal listing footprint, not contamination severity, cleanup stage, exposure, or current community risk.

The leader figures above come from database ranking rows, while the scope figures come from national aggregate counts. The page updates when the underlying portal database is refreshed; the current recorded vintage is .
Counts from different programs should not be combined into a single score. Reporting thresholds, program coverage, enforcement processes, and update timing differ by dataset. A high count can reflect more regulated entities or more monitoring, not necessarily worse conditions. For local decisions, inspect the underlying facility or water-system record and confirm it with the issuing agency.
