i <br /> I <br /> . Mass-Volume Calculation of Dissolved MTBE: 15 July 2004 to 23 Aug. 2004 <br /> RAINWATER CAR WASH - 420 West Yosemite Avenue, Manteca CA <br /> Assumptions <br /> o A total volume of 15,633 gallons was extracted from well EW-1 between 15 July& <br /> 23 Aug 2004 (based on influent flow meter observations) <br /> ' • Data collected from the pump and treat influent were representative of general <br /> extracted ground water conditions <br /> I �i <br /> One gallon of water Is equivalent to 3 79 liters, so the volume of processed water Is given by <br /> V= (15,633 gallons)(3 791/gal) = 59,2491 processed water <br /> Multiplying the volume of the processed water by the average July 2004 and the Aug 2004 <br /> MTBE concentrations (4,750 pg/1) yields the approximate mass of MTBE removed from <br /> processed water <br /> i , <br /> MMTBE _ (59,249 0(0 000004750 kg/O = 0.28 kg MTBE <br /> ® A converstion factor of 2 205 lb/kg can be used to convert kilograms of MTBE to pounds <br /> of MTBE <br /> MMrB2 _ (0 28 kg MTBE)(2 205 lb/kg) = 0.62 lb MTBE <br /> i <br /> 1 <br /> Advanced GeoEnvironmental,Inc <br />
