Automotive Service). CVRWQCB staff required that AGE provide additional <br /> information regarding the proposed mixture of hydrogen peroxide and muriatic acid <br /> (modified Fenton's Reagent). Specifically, CVRWQCB required further clarification on: <br /> 1) the amount of muriatic acid that is proposed to be used for the injection mixture, 2) <br /> what vendor/sub-contractor AGE could reference that has used the proposed mixture <br /> and 3) the final concentration of muriatic acid, which will be used in the injection <br /> mixture. Based on our research, AGE provides the following <br /> response: <br /> 1) What is the amount of muriatic acid that is proposed to be used for the injection <br /> mixture? <br /> In the AGE-prepared, In-Situ Chemical Oxidation Feasibility Study Work Plan, Section <br /> 5.1 ., AGE states that ".one liter of 50 mole hydrochloric or muriatic acid will be added <br /> to each mixture of 35 gallons." At the conclusion of each of the proposed injection <br /> events, a total of 9 liters <br /> will be mixed with a total of 315 gallons of water. <br /> 2) What vendor/sub-contractor can AGE reference that has used the proposed <br /> mixture? <br /> AGE staff has had several conversations with Ms. Cindy G. Schrier of Prima <br /> Environmental, regarding bench scale testing of hydrogen peroxide and modified <br /> Fenton's Reagent. Further, AGE has done Geotracker research on sites that have <br /> bench scaled tested the above referenced mixtures. For reference, AGE has provided <br /> an example (see attached Prima Report) of a bench scale pilot test performed for the <br /> Former Texaco Station, #21-1270 located at 712 G Street, Davis, California. In the <br /> attachment several mixtures of hydrogen peroxide, hydrogen peroxide and acid, <br /> hydrogen peroxide and chelated iron and acidified hydrogen peroxide and iron were <br /> laboratory applied to petroleum impacted soil and ground water samples collected <br /> from the referenced site. Based on the laboratory bench scale test it appears that the <br /> most effective mixtures were that of 2% peroxide and acid (63% of total contaminants <br /> destroyed) and 2% hydrogen peroxide with chelated iron and acid (66% of total <br /> contaminants destroyed). Based on the results of the attached pilot test, AGE <br /> concluded that the most cost-effective and sufficiently reactive media for the Boulevard <br /> 5 <br />
