i <br /> Mass-Volume Calculation of Dissolved MTBE - 13 May to 15 .Tune 2004 <br /> FLAG CITY CHEVRON- 6421 Capitol Avenue, Lodi, CA <br /> Assumptions <br /> • A total volume of 403,439 gallons was extracted from wells EW-4,EW-5,EW-7,EW-8 and <br /> EW-10 between 13 May and 15 June 2004 (based on effluent flow meter observations) <br /> • Data collected from the pump and treat influent water samples were representative of general = t- <br /> extracted ground water conditions <br /> One gallon of water is equivalent to 3 79 liters, so the volume of processed water is given by <br /> V= (403,439 gallons)(3 791/gal) = 1,529,0331 processed water <br /> Multiplying the volume of the processed water by the average of the May 2004 and the June 2004 <br /> MTBE concentrations (17 µg/1) yields the approximate mass of MTBE removed from processed <br /> water <br /> MMTBE= (1,529,033 1)(0 000000017 kg/1) = 0.026 kg MTBE (approx. 26 grams) <br /> A converstion factor of 2 205 lb/kg can be used to convert kilograms of MTBE to pounds of MTBE <br /> MMTBE = (0 026 kg MTBE)(2 205 lb/kg) =0.06 lb MTBE <br /> Advanced GeoEnv:ronmental,Inc <br />
