1 <br /> Mass-Volume Calculation of Dissolved MTBE: 01 April to 17 April 2002 <br /> RAINWATER CAR WASH- 420 West Yosemite Avenue,Manteca CA <br /> ' Assumptions <br /> ' A total volume of 44,820 gallons was extracted from well EW-1 between 01 April and 17 <br /> April 2002 (based on effluent flow meter observations) <br /> ' • Data collected from the pump and treat influent were representative of general extracted <br /> ground water conditions <br /> One cubic foot of water contains 7 48 1 gallons, conversely, one gallon of water is equivalent to II <br /> 0 1337 cubic feet, so the volume of processed water is given by <br /> V= (44,820 gallons)(0 1337 ft3/gal) =5992.4 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 /> Mwatvr= (44,820 gallons)(8 337 lbs/gal) =373,664 lbs. processed water <br /> Multiplying the mass of the processed water by the average MTBE concentration(54,000µg/l)yieids <br /> the approximate mass of MTBE removed from processed water <br /> ' MMTnE =(373,664 lbs)(0 000054000) =20.18 lbs MTBE <br /> ' A converstion factor of 0 4536 kg/Ib can be used to convert pounds of MTBE to kilograms of <br /> MTBE <br /> ' MmTBE=20 18 lbs MTBE(0 4536 kg/lb) =9,153 g of MTBE <br /> 1 <br /> 1 , <br /> ' Advanced GeoEnvironmental,Inc <br /> I <br /> i <br /> 1 i <br />
