Mass -Volume Calculation of Dissolved MTBE - 22 May 2002 to 13 April 2002 <br />0 FLAG CITY CHEVRON - 6421 Capitol Avenue, Lodi, CA <br />Assumptions <br />• A total volume of 417,956 gallons was extracted from wells EW -4, EW -5, EW -9 and EW -10 <br />between 22 May and 13 April 2002 (based on effluent flow meter observations) <br />• Data collected from the pump and treat influent and extraction well -head grab ground water <br />samples were representative of general extracted ground water conditions <br />One cubic foot of water contains 7 48 gallons, conversely, one gallon of water is equivalent to <br />0 1337 cubic feet, so the volume of processed water is given by <br />V= (417,956 gallons)(0 1337 ifi /gal) = 55,880 ft' processed water <br />One gallon of water weighs 8 337 lbs /gal at 60°F, so the mass of processed water is given by <br />MW.,?, = (417,956 gallons)(8 337 lbs /gal) = 3,484,499 lbs. processed water <br />Multiplying the mass of the processed water by the average MTBE concentration (05-22-02= 28µg/1, <br />06-13-02 = 19 ug/l, avg = 23 5 µg/l) yields the approximate mass of MTBE removed from <br />processed water <br />MmnE _ (3,484,499 Ibs)(0 0000000235) = 0.08 lbs MTBE <br />A converstion factor of 0 4536 kg/lb can be used to convert pounds of MTBE to grams of MTBE <br />MmTBE = 0 08 lbs MTBE (0 4536 kg/lb) = 36 g of MTBE <br />Advanced GeoEnvironmental, Inc. <br />
