Mass-Volume Calculation of Dissolved Hydrocarbons <br /> PACIFIC MINI MART - First Quarter 2003 <br /> 4511 Pacific Avenue, Stockton, California <br /> Assumptions <br /> A total volume of 92,546g allons was extracted from between 31 December 2002 and <br /> 27 March 2003 based on effluent flow meter observations Data collected from the influent pump <br /> and treat grab water samples were representative of general extracted ground water conditions <br /> i <br /> One gallon of contains 3 785 liter so the volume of processed water expressed as liters is <br /> V= (92,546 gallons)(3 785 l/gal) = 350,286 liter processed water <br />' Multiplying the volume of the processed water by the cumulative average MTBE concentration <br /> (240µg11, 210µg/1, 290 µg/1, 250 µg/1) yields the approximate mass of MTBE removed from <br /> processed water <br /> MMTBE = (350,286 liters)(247 5 µg/1) = 86,698,785 µg MTBE <br /> MMTBE as grams 86 g MTBE <br /> MMTBE as kilograms 0.086 kg MTBE <br /> A conversion factor of 2 205 lb/kg can be used to convert MTBE to pounds <br /> MMTBE = 0 086 kg MTBE (2 205 lb/kg) = 0.191 lbs of MTBE <br /> lie Multiplying the volume of the processed water by the cumulative average benzene concentration <br /> (230µg/1, <5 0 g/l, 270 µg/1, 320 µg/1) yields the approximate mass of benzene removed from <br />' processed water <br /> M Benzene = (350,286 liters)(206 µg/1 average) =7,215,891 µg benzene <br />' M Benzene as grams 7.2g benzene <br /> M ae�ene as kilograms 0 0072 kg benzene <br /> A conversion factor of 2 205 lb/kg can be used to convert benzene to pounds <br />' M benzene = 0 0072 kg benzene(2 205 lb/kg) = 0.0159 lbs of benzene <br /> Multiplying the volume of the processed water by the cumulative average TPH-g concentration <br />' (1,100µg/1, 170 µg/1, 2,600 µg/l, 2,500 gg/1) yields the approximate mass of TPH-g removed from <br /> processed water <br /> MTPH_g= (350,286 liters)(1,592 5 µg/1) = 5.59x108 µg TPH-g <br /> MTPH_g as grams 557 g TPH-g <br /> MTPH-g as kilograms 0.5578 kg TPH-g <br /> A conversion factor of 2 205 lb/kg can be used to convert TPH-g to pounds <br /> MTPH_g= 0 5578 kg TPH-g (2 205 lb/kg) = 1 229 lbs of TPH-g <br />' Advanced GeoEnvironmental,Inc <br /> 1 <br />
