GP-2 Soil Sample <br /> ' The soil samples taken from GP-2 on February S, 2004 had gasoline loadings of 6000 mg/kg at <br /> 20 R depth, 74 mg/kg at 24 f1, and 33 mg/kg at 28 ft A simple integration of the organic loading <br /> based on these soil samples over the eight foot radius of the wells and 20 ft depth is about 225 <br /> ' pounds of organic in the soil The average organic in the water phase was 140 ppm when the test <br /> began The organic dissolved in water phase would be about 1 1 pounds The nature of clay is <br /> similar to carbon in that it adsorbs organic compounds, thereby containing the majority of the <br /> mass in the subsurface This also causes dissolved hydrocarbon concentrations to be lower and <br /> not indicative of the hydrocarbon mass actually in the subsurface Clay can also trap pockets of <br /> separate-phase product Hydrogen peroxide can act like a surfactant and mobilize organics that <br /> Applied Process Technology,Inc Confidential Infonnation <br /> 09/20/04 mage 6 of I 1 !" <br /> APT SO 019 www��twater ow <br /> 1 <br />
