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

This edition of the Toxic 100 Water 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 2018.

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, 2018; (2) toxicity weights and hazard calculation: US EPA's Risk Screening Environmental Indicators, version 2.3.8. 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 World's Largest Public Companies 2020 list, the Forbes America's Largest Private Companies 2019 ranking, the Fortune 500 list for 2020, the Fortune Global 500 for 2020, or the S&P 500 as of 8/22/2020.  Individual facilities are assigned to corporate parents on the basis of the most current information on their ownership structure as of late 2020.  
Source: CTIP.

The links from each parent name lead to an application that gives detailed facility and sector information about the company. You can also search for companies not on the Toxic 100 Water. For more information on the data, see the technical notes.
