I <br /> I r <br /> . APPENDIX K <br /> I GROUND WATER PUMP-AND-TREAT VOLUME-MASS CALCULATIONS <br /> TOP FILLING STATION <br /> 101 South Wilson Way, Stockton CA <br />' 1) 29 December 2004 - 20 January 2005 <br /> Assumptions <br /> • A total volume of 26,620 gallons was extracted from wells EW-1 and EW-2 between 29 <br /> IDecember 2004 and 20 January 2005 (based on effluent flow meter observations) <br /> • Data collected from the pump and treat influent were representative of general extracted <br /> Iground water conditions <br /> One gallon of water is equivalent to 3 79 liters, so the volume of processed water is given by <br /> V= (26,620 gallons)(3 79 1/gal) = 100,890 l processed water <br />' Multiplying the volume of the processed water by the average of the December 2004 and the January <br /> 2005 TPH-g concentrations (25,500 µg11) yields the approximate mass of TPH-g removed from <br /> processed water <br /> MTpH_g= (100,8901)(0 000025500 kg/1) = 2.57 kg TPH-g <br /> IA converstion factor of 2 205 lb/kg can be used to convert kilograms of TPH-g to pounds of TPH-g <br /> MTpH_g= (2 57 kg TPH-g)(2 205 lb/kg) = 5.67 lb TPH-g <br /> I <br /> I <br /> • <br /> Advanced GcoEnvironmental,Inc <br /> I <br />
