• Mass-Volume Calculation of Dissolved MTBE: 27 March 2003 to 15 April 2003 <br /> RAINWATER CAR WASH -420 West Yosemite Avenue,Manteca CA r <br /> ' Assumptions <br /> ' • A total volume of 7,645 gallons was extracted from well EW-1 between 27 March 2003 and <br /> 15 April 2003 (based on influent flow meter observations) <br /> ' • Data collected from the pump and treat influent were representative of general extracted <br /> 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=(7,645 gallons)(3 791/gal) =28,975 l processed water <br /> Multiplying the volume of the processed water by the average of the March 2003 and April 2003 <br /> MTBE concentrations(9,150 µg/1)yields the approximate mass of MTBE removed from processed <br /> water <br /> MMTBE = (28,975 0(0 00000915 kg/0 =0.265 kg MTBE <br /> A converstion factor oft 205 lb/kg can be used to convert kilograms of MTBE to pounds of MTBE <br /> 4' <br /> MMTBE= (0 265 kg MTBE)(2 205 lb/kg) = 0.58 lb MTBE <br /> ' I <br /> I ' <br /> I <br /> Advanced GeoEnvironmental,Inc <br /> I I I <br /> e <br /> I I I I I <br /> I� 'I <br />
