�J N - - 13 May 2010 AGE-NC Project No . 07-1529 Page 2 of 11 2.0. ISCO AND AEROBIC BIOREMEDIATION RegenOxTM is designed by Regenesis of San Clemente, California (www.regenesis. com) as an advanced chemical oxidation technology that destroys contaminants through powerful, yet controlled chemical reactions for periods up to 4 weeks . RegenOxTM is a patented material distributed by Regenesis to provide an advanced chemical oxidation media to destroy contaminants through controlled chemical reactions which oxidizes contaminants using a solid alkaline oxidant that employs a sodium percarbonate complex within a multi-part catalytic formula. Background information about RegenOxTM is included in Appendix B. ORC Advanced® is also produced by Regenesis, designed to stimulate aerobic bioremediation by providing a controlled oxygen release for periods up to 12 months in a single application. ORC Advanced® is a proprietary formulation of food-grade, calcium oxy-hydroxide that can accelerate the rate of naturally occurring aerobic contaminant biodegradation in ground water and saturated soils. Background information about ORC Advanced® is included in Appendix C . 2 . 1 . RegenOxTM PRACTICE AND PRINCIPALS RegenOxTM is a patented material distributed by Regenesis to provide an advanced chemical oxidation media to destroy contaminants through controlled chemical reactions to oxidize contaminants using a solid alkaline oxidant that employs a sodium percarbonate complex with a multi-part catalytic formula. RegenOxTM directly oxidizes contaminants while its unique catalytic component generates a range of highly oxidizing free radicals that rapidly and effectively destroy a range oftarget contaminants including total petroleum hydrocarbons quantified as gasoline (TPH-g), benzene and 1 ,2-dichloroethane ( 1 ,2-DCA). RegenOxTM also releases a quantity of oxygen that can provide a smooth transition to bioremediation. 2. 1 . 1 . RegenOxTM Application and Reaction RegenOxTM is usually delivered to the subsurface by pressure injection using direct push methods. Injection of RegenOxTM through wells may be achieved, however the well may experience residual product and required cleaning. RegenOxTM application process consists of two components, Part A (oxidizer) and Part B (catalyst). RegenOxTM is supplied to the environment (soil and ground water) as liquid slurry of Part A, Part B and water, which interacts with ground water and then produces a cascade of efficient oxidation reactions via several mechanisms that include surface mediated oxidation, direct oxidation and free radical oxidation. These reactions destroy a range of contaminants and can be propagated in the presence of RegenOxTM for periods of up to 30 days on a single injection. RegenOxTM produces minimal heat and is highly compatible with follow-on Advanced GeoEnvironmental, Inc.
