POST-REMEDIATION EVALUATION OF EVO TREATMENT: HOW CAN WE IMPROVE PERFORMANCE?
Borden, R.
Project ER-201581, Excel Spreadsheet Design Tool, 2018

Conclusions and lessons learned in this demonstration project were integrated with prior lab and field studies to generate a general conceptual model of enhanced reductive dechlorination (ERD) with emulsified vegetable oil (EVO) and pH buffer. The conceptual model on which this design tool is based provides a relatively concise summary of the current understanding of ERD with EVO, including (1) ERD microbiology and organohalide respiration; (2) environmental requirements for efficient dechlorination; (3) EVO properties, transport and retention in the subsurface; (4) EVO consumption during ERD; (5) aquifer pH and buffering; and (6) injection system design.
