Mass-Volume Calculation of Dissolved Hydrocarbon-Impact <br /> PACIFIC MINI MART <br />' 4511 Pacific Avenue, Stockton, California <br /> IAssumptions <br /> • A total volume of 126,250 gallons was extracted from between 12 October and 13 November <br /> I2001 based on effluent flow meter observations until 13 November 2001 <br /> • Data collected from the influent pump and treat grab water samples were representative of <br />' general extracted ground water conditions <br />' One gallon of contains 3 785 liter so the volume of processed water expressed as liters is <br /> V= (126,250 gallons)(3 785 1/gal) = 477,856.25 Mer processed water <br />' Multiplying the volume of the processed water by the average MTBE concentration(2,100 ,ug/1 and <br /> 2450µg11) yields the approximate mass of MTBE removed from processed water <br /> I MMTBE = (477,856 25 liter)(2,775 yg/1) = 1,326,051,094,ug MTBE <br /> MMTBE as grams 1,326 g MTBE <br /> MMTIaE as kilograms 1 326 kg MTBE <br /> A conversion factor of 2 205 lb/kg can be used to convert MTBE to pounds <br /> MMTBE = 1 326 kg MTBE (2 205 lb/kg) =2.86 lbs of MTBE <br /> Multiplying the volume of the processed water by the cumulative average BTEX concentration yields <br /> the approximate mass of BTEX removed from processed water <br /> MBTEX =(477,856 25 liter)(403 ug/1) = 192,653,619.6 pug BTEX <br /> MBTEX as grams 192 g BTEX <br /> MBTEX as kilograms 0.192 kg BTEX <br /> A conversion factor of 2 205 lb/kg can be used to convert BTEX to pounds <br /> MBTEX = 0 192 kg BTEX (2 205 lb/kg)= 0 42 lbs of BTEX <br /> Advanced Geo Environmental,inc <br />
