"SACRAMENTO -- The U.S. Environmental Protection Agency today ordered a $60 million cleanup of groundwater polluted with rocket fuel at the Aerojet Superfund Site in Sacramento County, the latest phase of a long-term decontamination project at the site."

"The extent of pollution at the site makes it one of the largest and most comprehensive Superfund groundwater cleanups in California.

A 27-square mile area of groundwater underneath and around the former aerospace facility is polluted with several compounds, including very high levels of perchlorate, a main component of rocket fuel, and a known developmental toxin.

Aerojet, under the direction of the EPA, will contain the underground plume to prevent it from spreading into nearby rivers and streams. Future plans will also treat groundwater within the site's boundaries."
