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 passed through publicly owned treatment works from large facilities in the US in 2017.

RSEI Hazard: Pounds released directly to surface water plus estimated pounds released post-treatment multiplied by chemical-specific toxicity weights.  Sources: (1) pounds released and transferred: US EPA's Toxics Release Inventory, 2017; (2) toxicity weights and post-treatment release estimate: US EPA's Risk Screening Environmental Indicators, version 2.3.7. 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.

Toxics released to surface water: Millions of pounds of toxic chemical released directly to water on-site plus estimated post-treatment release to surface water from toxic chemicals transferred to Publicly Owned Treatment Works (POTWs) for sewage treatment (POTWS do not have the equipment necessary to remove all toxics from the waste stream). Source: U.S. EPA.

Coverage: This table presents the RSEI Hazard score companies that appear on the Forbes World's Largest Public Companies list (2018, first 500 companies only), the Forbes America's Largest Private Companies list (2018 ranking), the Fortune 500 list (FY 2017-2018), the Fortune Global 500 (FY 2017-2018), or the S&P 500 as of 2/1/2019.  Individual facilities are assigned to corporate parents on the basis of the most current information on their ownership structure as of late 2018.  
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.
