- Prior operations at a former plating and hard anodizing facility in Santa Clara, California resulted in tetrachloroethene (PCE), trichloroethene (TCE), and cis-1,2-dichloroethene (DCE) impacts to soil and groundwater.
- In 1987, a groundwater monitoring program was implemented to monitor the plume.
- In 1998, CDM performed a natural attenuation evaluation for the site and determined that the rate of natural attenuation was adequate to prevent the plume from migrating further.
- In 1999, CDM evaluated several remedial alternatives for the site, including monitored natural attenuation, enhanced anaerobic biodegradation (EAB), groundwater pump and treat (P&T), and chemical oxidation.
