Subject: [CPEO-MEF] PERCHLORATE: Rialto, California cleanup plan
EPA: Pump Rialto groundwater and cleanse it of perchlorate

Riverside Press-Enterprise (CA)
February 3, 2010

Federal environmental regulators on Wednesday unveiled a $29.3 million plan to clean up a Rialto Superfund site by pumping tainted groundwater and treating it to remove perchlorate and other toxic contaminants.

The water then could be delivered to homes and businesses.

The 160-acre industrial site north of Interstate 210, between Alder and Locust avenues, was used by private companies and the government to store, test and manufacture munitions, rocket motors and fireworks.

Perchlorate, an ingredient in rocket fuel, and the industrial solvent trichloroethylene, TCE, were spilled or dumped on the ground and seeped deep into the aquifer. Spreading for miles southeast of the site, the contamination is the Inland region's largest uncontrolled plume of perchlorate in a drinking water supply.
