Golden State Water Company first detected in 2010 in wells near the  
home of the former owner of the Mojave River Pyrotechnics Company.

Starting in Dec. 2010, the EPA sampled soil from 25.5 acres of the  
former pyrotechnics facility and the owner’s nearby residence. They  
found concentrations at the residence as high as 130,000 milligrams  
of perchlorate per kilogram of soil, much higher than the allowed  
level of 55 milligrams per kilogram. Sampling of groundwater showed  
concentrations of 110,000 micrograms per liter. No contamination was  
found at the pyrotechnics manufacturing facility.
