Explanatory notes (For details, see the technical notes).
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, 2014; (2) toxicity weights and post-treatment release estimate: US EPA’s Risk Screening Environmental Indicators, version 2.3.4. 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. Source: U.S. EPA.
