FLASH POSTER PRESENTATION
Applying Injection Techniques to Enhance or Eliminate Construction of a Passive Reactive Barrier at Two Sites
Passive Reactive Barriers (PRBs) can be costly to construct and limited in their application depending on site constraints and other factors. Wood was able to effectively achieve remedial objectives at two Sites while eliminating the need to perform open cut excavation PRB construction and the hazards associated with such construction. The first Site involved extending a conventional PRB into an access constrained area utilizing direct injection techniques, to enhance the PRBs effectiveness at treatment of chlorinated VOCs. A second chlorinated VOC site also had a number of site constraints that would have made open trench PRB installation impracticable and less likely to meet the clients objectives. This presentation will review the rationale for utilizing direct injection over a conventional PRB, review design of the direct injection programs, and present the effectiveness of each application at achieving remedial action objectives.
