Explanatory notes (For details, see the technical notes).

This edition of the Toxic 100 Water Polluters ranks companies by comparative chronic human health hazard from water pollutants directly released or transferred to publicly owned treatment works from large facilities in the US in 2022.

RSEI Hazard: Pounds released directly to surface water plus pounds transferred to POTWs multiplied by chemical-specific toxicity weights.  Sources: (1) pounds released and transferred: US EPA's Toxics Release Inventory, 2022; (2) toxicity weights and hazard calculation: US EPA's Risk Screening Environmental Indicators, version 2.3.12. For details, see Technical Notes.

Toxics released directly to surface water or transferred to sewage treatment: Millions of pounds of toxic chemicals released directly to water on-site at each TRI facility or transferred off-site to Publicly Owned Treatment Works (POTWs) for sewage treatment, without weighting for toxicity. Source: U.S. EPA.

Coverage: This table presents the RSEI companies that appear on the Forbes Global 2000 list, the Forbes America's Largest Private Companies list, the Fortune 500 list, the Fortune Global 500 list, the Russell 1000 list, or the S&P 500.  Individual facilities are assigned to corporate parents on the basis of the most current information on their ownership structure as of mid 2024. Source: CTIP.

Environmental Justice (EJ): Near Poor Share and Minority Share: Shares of the total population health hazard borne by people living below twice the poverty line or by people in minority racial/ethnic groups. In the U.S. population, 26 percent lived below twice the poverty line in 2020 and 40 percent are members of minority racial/ethnic groups.  
Sources: US EPA, US Census, and CTIP.
