LOS ANGELES — Mining company TDY Industries Inc. has agreed to pay $1.44 million to help cover costs for groundwater cleanup at the South El Monte portion of the San Gabriel Valley Area 1 Superfund site in Los Angeles.
The San Gabriel Valley Area 1 site is an area of contaminated groundwater over four miles long and 1½ miles wide located in the San Gabriel Valley. In 1984, the EPA identified four large areas of groundwater contamination in the San Gabriel Valley; each area is a separate Superfund site.
Groundwater and soil are contaminated with various volatile organic compounds (VOCs), predominantly trichloroethylene (TCE) and tetrachloroethylene (PCE).

Since the U.S. Environmental Protection Agency (EPA) began cleaning up this site in 2008, more than 12.5 billion gallons of drinking water have been treated and approximately 5,500 pounds of contaminants have been removed from the groundwater.
The current water treatment systems at the site operate continuously at an annual cost of more than $2 million.

TDY owned and operated a facility in South El Monte that was used to manufacture metal casings and electronics and re-condition drums.
This is part of an overall $1.8 million settlement brought by the U.S. Department of Justice on behalf of EPA against TDY Industries, LLC (formerly known as TDY Industries, Inc., or Teledyne Industries, Inc.) and its affiliated entities Allegheny Technologies Incorporated, and TDY Holdings for the contributions its facility made to the contamination in South El Monte. Of the entire settlement, $1.44 million will be paid to EPA and $360,000 will be paid to the San Gabriel Basin Water Quality Authority for the groundwater treatment.
“This settlement brings the total amount recovered to almost $27 million to pay for the cleanup of polluted groundwater,” said Jared Blumenfeld, EPA’s Regional Administrator for the Pacific Southwest. “Our goal is to protect and restore the safe drinking water supplies for the San Gabriel Valley communities.”
