Explanatory notes (also see the technical notes):

  • Toxic Hazard: Pounds released directly to surface water plus pounds estimated released post-treatment multiplied by chemical-specific toxicity weights.  Sources: (1) pounds released and transferred: US EPA's Toxics Release Inventory, 2009; (2) toxicity weights and post-treatment release estimator: US EPA’s Risk Screening Environmental Indicators, version 2.3.0. For details, see Technical Notes.

  • Toxics released directly to surface water and pounds transfered to sewage treatment: Millions of pounds of toxic chemicals released directly to water on-site at each TRI facility or transferred off-site to POTW’s for sewage treatment, without weighting for toxicity.

  • Total toxics released to surface water: Millions of pounds ot toxic chemical released directly to water on-site plus estimated post-treatment release to surface water of toxic chemical transfered to POTW’s for sewage treatment.

  • Coverage: This table presents the RSEI Hazard for companies and agencies reporting to the US EPA’s Toxics Release Inventory. Individual facilities are assigned to corporate parents on the basis of 2011 information on the ownership structure.
