2) If necessary, prior to performance of the field scale test, onsite tap water would be <br /> sampled and evaluated for chlorine. Results could be used to evaluate the potential of <br /> any adverse chlorine gas production. <br /> 3) To further protect the safety of the onsite AGE representative during mixing and <br /> injecting of the solution, level C personal protective equipment will be used, which will <br /> include the use of an air purifying respirator, rubber gloves, eye goggles and a full face <br /> shield. <br /> 4) AGE has previously performed similar pilot test injections at the Davis Texaco site <br /> located at 2002 Lyndell Terrace, Davis, California. During mixing and injection <br /> activities, AGE did not experience any adverse effects that would prevent proposing <br /> such work at the Boulevard Auto site. Findings from the AGE-prepared, In-Situ <br /> Chemical Oxidation Pilot Study Report, dated <br /> 06 October, 2010, can be referenced on the California state Geotracker website. <br /> Should you have any further question or concerns, please do not hesitate to contact <br /> me. <br /> Best Regards, <br /> Daniel Villanueva <br /> Staff Geologist <br /> Advanced GeoEnvironmental, Inc. <br /> Stockton .

The bench scale test used sulfuric acid (H2SO4). The HCI MSDS says: <br /> 2 <br />
