Delivery of a Permeable Injection Network for Enhanced Reductive Dechlorination Treatment:Adapting to Site Challenges

Session:
C3: innovative & Optimized Delivery Methods

Site Remediation

 

At this site, pilot testing proved that distribution objectives did not meet goals. Cascade subsidiary, GeoSierra, with Tetra Tech developed a technical approach involving the use of multiple techniques and approaches for amendment installation. Combined pneumatic and hydraulic fracturing was used to develop inclusions for amendment distribution. 

Following permeability enhancements, in situ bioremediation amendments were injected using conventional approaches. 

Groundwater results showed continued contaminant degradation and increases in daughter products.
