The Toxic 100 Water Polluters

May 2013 -- The Toxic 100 Water Polluters index identifies the top companies and Federal agencies responsible for industrial water pollution. The index relies on the U.S. Environmental Protection Agency's Risk Screening Environmental Indicators (RSEI), which assesses the hazard from industrial toxic releases. The underlying data for RSEI is the EPA’s Toxics Release Inventory (TRI), in which facilities across the U.S. report their releases of toxic chemicals to water and other media. In addition to the amount of toxic chemicals released, RSEI also includes the degree of toxicity. The Toxic 100 Water Polluters ranks corporations based on the toxicity-weighted pounds of toxic releases to water from all of their U.S. polluting facilities.

>> In 2014, Ohio Valley Electric, previously ranked at number one among the Toxic 100 Water Polluters, submitted new data to the U.S. E.P.A. revising its 2009 TRI reporting. Ohio Valley Electric has revised its reported water release of 27,090 pounds arsenic or arsenic compounds to 814 pounds. Based on the revision, Ohio Valley Electric is ranked 28th on the Toxic 100 Water Polluters with a RSEI Hazard of 1,249,698,036. The next edition of the Toxic 100 will reflect the most current information from U.S. E.P.A.
