Combined Remedy Treats TCE Plume at Aerospace Site

Case study highlights:

• Combined remedy was three times the cost savings vs. alternative remedial technologies being considered
• Completed the application event ahead of schedule
• Successful reductions in cVOCs observed

This case study reviews an aerospace manufacturing facility in Southern California that required remediation for a deep and heavily impacted Trichloroethene (TCE) plume. The extensive depth and size of the plume contributed to the difficulty facing remediation efforts, with much of the contaminant plume extending offsite. Alta Environmental and REGENESIS began developing an approach to remediate this site in 2012. After conducting pilot tests, they concluded that Enhanced In-Situ Bioremediation (EISB) technology was both cost-effective and feasible for successful remediation of this site. The observation wells continue to be sampled quarterly and are displaying successful reductions in cVOCs.
