• AquiFix is the first ever micron-scale, solid electron donor to promote the effective treatment of chlorinated solvents
• Total CVOC concentrations in groundwater were reduced by 97% in one month and further reduced by >99% after two years of monitoring
• AquiFix technology is chemically compatible, and designed for direct mixing and co application with colloidal amendments like PlumeStop and S-MicroZVI

AquiFix, a new co-injectable remediation substrate formulated to rapidly establish and sustain anaerobic biodegradation of chlorinated volatile organic compounds (CVOCs) over extended timeframes, was field tested at a CVOC plume site in Southern Michigan. The two-year-long field trial involved installing two short permeable reactive barriers (PRBs) for testing AquiFix. PlumeStop, a patented colloidal activated carbon amendment, was mixed with AquiFix and injected at one of the PRBs, while only AquiFix was injected at the other PRB.

With the demonstration period now complete, the pilot test has shown that CVOCs can be rapidly removed from groundwater and effectively treated in an extreme mass flux environment using a mixture of PlumeStop and AquiFix. In this system, PlumeStop significantly retards the CVOCs, allowing AquiFix to facilitate their complete reductive dechlorination, regenerating PlumeStop’s sorption surface.
