' Mass-Volume Calculation of Dissolved MTBE: 19 June 2003 to 11 July 2003 <br /> iRAINWATER CAR WASH - 420 West Yosemite Avenue, Manteca CA <br /> ' Assumptions <br /> ' • A total volume of 41,071 gallons was extracted from well EW-1 between 19 June 2003 and <br /> 1 l July 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= (41,071 gallons)(3 791/gal) = 155,6591 processed water <br /> ' <br /> Multiplyingthe volume of the processed water b the average of the June 2003 and Jul 2003 MTBE <br /> p Y g July <br /> 2003 <br /> (3,850 µg11) yields the approximate mass of MTBE removed from processed water <br /> M14TBF = (155,6591)(0 00000385 kg/0 = 0.599 kg MTBE <br /> ' A converstlon factor of 2 205 lb/kg can be used to convert kilograms of MTBE to pounds of MTBE <br /> i <br /> 10 MMTBE= (0 599 kg MTBE)(2 205 lb/kg)= 1.32 lb MTBE <br /> 1 <br /> 1 <br /> Advanced Gea,Euvironmenta1,Inc <br />
