1 <br /> . Mass-Volume Calculations: 04 August to 27 September 2004 <br /> ' LOCAL FOOD STORE <br /> 2650 Monte Diablo Avenue, Stockton, California <br /> ! Assumptions <br /> ! • A total volume of 1,660 gallons was extracted between 04 August and 06 August 2004, and <br /> a total volume of 65,100 gallons were extracted between 06 August and 27 September 2004 <br /> (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 /> ' 04 August to 06 August <br /> One gallon of water is equivalent to 3 79 liters (L), so the volume of processed water is given by <br /> V= (1,660 gallons)(3 79 L/gal) = 6,291 L processed water <br /> ' Dissolved MTBE <br /> ' Multiplying the volume of the processed water by the 06 August MTBE concentration (48 µg11) <br /> yields the approximate mass of MTBE removed from processed water <br /> ' MMTBE— (6,291 L)(0 000000048 kg/L)= 0.0003 kg MTBE <br /> A conversion factor of 2 205 lbs/kg can be used to convert kilograms of MTBE to pounds of MTBE <br /> ' Mm-FBF= (0 0003 kg MTBE)(2 205 lbs/kg) = 0.0007 lbs MTBE <br /> ' Dissolved TPH-g <br /> ' Multiplying the volume of the processed water by the 06 August TPH-g concentrations (450 µg11) <br /> yields the approximate mass of TPH-g removed from processed water <br /> ! MTPH g= (6,291 L)(0 000000045 kg/L) = 0.0028 kg TPH-g <br /> ' A conversion factor of 2 205 lbs/kg can be used to convert kilograms of TPH-g to pounds of TPH-g <br /> MTPH g= (0 0028 kg TPH-g)(2 205 lbs/kg) = 0 0062 lbs TPH-g <br /> Advanced GeoEnvironmental,Inc <br />
