pounds of toxic residue left over from the Jet Propulsion  
Laboratory's early rocket-building days.

The $8.5 million Monk Hill water treatment facility has removed 674  
pounds of perchlorate from 7,773 acre-feet of water since it opened  
in 2011, said Steve Slaten, a NASA remediation project manager.  
Twenty-three pounds of trichloroethylene, an industrial solvent, have  
also been removed from the water supply.

was conduced in 1936 in the Arroyo Seco, in the area where the lab  
now sits. Most of the waste dumping occurred in the 1940s and '50s.
