OxyVAC™ IN-SITU OXIDATION SYSTEM OXY VAC™ Process Description The process of injecting concentrated oxidants (including hydrogen peroxide) has been used to treat soil and wastewater for many years.  Terra Vac developed and patented the process of combining in-situ oxidant injection with vacuum extraction, Dual Phase Extraction, or air sparging (Oxy VAC™) to enhance the distribution of oxidant in the subsurface as well as capture off gasses that are created as a result of the exothermic reaction.  This process is especially effective for the remediation of MTBE and its degradation products. The process has been used for source area treatment as well as large full-scale area treatment and as a barrier for off-site migration. Some advantages of this technology are that it: •Minimizes the need for groundwater extraction; •Increase the effectiveness of DVE, and Air Sparging; •Enhances down-gradient biodegradation; and is a •Rapid low cost remedial solution.
