i Mass-Volume Calculation of Dissolved Hydrocarbons PACIFIC MINI MART ' 4511 Pacific Avenue, Stockton, California Assumptions ' A total volume of 168,211 gallons was extracted from between June and August 2002 based on effluent flow meter observations Data collected from the influent pump and treat grab water samples were representative of general extracted ground water conditions One gallon of contains 3 785 liter so the volume of processed water expressed as liters is I V= (168,211 gallons)(3 7851/gal) = 636,679 liter processed water Multiplying the volume of the processed water by the average MTBE concentration (360 gg/l, 200 gg/l, and 270 gg/l) yields the approximate mass of MTBE removed from processed water MMTBE — ( 636,679 liter)( 277 4g/1) = 176,359,982 µg MTBE MMTBE as grams 176 g MTBE MMTSE as kilograms 0.18 kg MTBE A convex sion factor of 2 205 lb/kg can be used to convert MTBE to pounds KrrBE = 0 18 kg MTBE (2 205 lb/kg) = 0 39 lbs of MTBE Multiplying the volume of the processed water by the cumulative average benzene concentration yields the approximate mass of benzene removed from processed water IM Benzene = ( 636,679 litei)(243�Lg/l average) = 154,925,223 µg benzene M Benzene as grams 155 g benzene M Benzene as kilograms 0 155 kg benzene IA conversion factor of 2 205 lb/kg can be used to convert benzene to pounds M benzene = 0 155 kg benzene(2 205 lb/kg) = 0.34 lbs of benzene ' Multiplying the volume of the processed water by the cumulative avec age TPH-g concentration yields the approximate mass of TPH-g removed from processed water ' MTEH_g= ( 636,678 liter)(3,500 gg/1) = 2.2x109 pg TPH-g MTPH_g as grams 2,228 g TPH-g MTpH_g as kilograms 2.2 kg TPH-g A conversion factor of 2 205 lb/kg can be used to convert TPH-g to pounds MTPH g= 2 2 kg TPH-g (2 205 lb/kg) =4.9 lbs of TPH-g Advanced GeaEnvwonmental,Inc I I
