- Prior operations at a former Microwave electronics facility inSunnyvale, California, resulted in tetrachloroethene (PCE), trichloroethene ( TCE), cis-1,2-dichloroethene (DCE) and vinyl chloride (VC) impacts to soil and groundwater.
- In 1985, a groundwater pump and treat (P&T) system was implemented to address groundwater impacts.
- In 1996, CDM began evaluations of the effectiveness of the P&T system in terms of mass removal of contaminants from the aquifer. CDM concluded that the P&T system was no longer cost effectively removing contaminant mass and began to evaluate alternative remediation technologies.
