' Mass-Volume - <br /> • olume Calculation of Dissolved MTBE Third Quarter 2001 <br />' FLAG CITY CHEVRON- 6421. Capitol Avenue,Lodi, CA <br /> Assumptions. <br />' • A total volume of 1,923,307 gallons was extracted from wells EW-2, EW-4, EW-5, EW-6, <br /> EW-7, EW-8, EW-9 and EW-10 between 02 July 2001 and 06 September 2001 (based on <br />' effluent flow meter observations between 02 July and 06 September 2001) <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= (1,923,307 gallons)(0 1337 ft/gal)=257,146 fe 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 /> =(1,923,307 gallons)(8 337 lbs/gal) = 16,034,610 lbs. processed water <br />�. Multiplying the mass of the processed water by the average MTBE concentration (07-02-01= <br /> 28pg/L, 08-01-01= 19 kiglL, 09-06-01= 7,ug/L, avg = 15 Ag/L) yields the approximate mass of <br /> MTBE removed from processed water <br /> MhrrsE = (16,034,610 lbs)(0 000000015) =0.24 lbs MTBE <br /> A converstion factor of 0 4536 kg/lb can be used to convert pounds of MTBE to kilograms of <br /> MTBE <br /> MrrsE = 0 24 lbs MTBE (0 4536 kg/lb) = 110 g of MTBE <br /> IAdvanced GecEnvirnnmentai,Inc. <br />
