Appendix I - Ground Water P&T Volume-Mass Calculations <br /> AGE-NC Project Nol 95-0130 <br /> Page 3 of 3 <br /> I3) 07 February 2006- 14 March 2006 <br /> Assumptions <br /> • A total volume of 146,180 gallons was extracted from wells EW-1,EW-2,VW-1C,VW-2A <br /> and VW-3A between 07 February 2006 and 14 March 2006 (based on effluent flow meter <br />' 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= (146,180 allons)(3 79 l/ al) =554,022 l processed water <br /> Multiplying the volume of the processed water by the average of the February 2006 and the March <br /> 2006 TPH-g concentrations (20,500 µg/1) yields the approximate mass of TPH-g removed from <br /> processed water <br /> MTPH_g=(554,022 I)(0 000020500 kg/I)= 11.36 kg TPH-g <br /> A canvershon factor of 2 205 lb/kg can be used to convert kilograms ofTPH-g to pounds of TPH-g <br /> MwIj_8= (11 36 kg TPH-g)(2 205 lb/kg)= 25.05 lb TPH-g <br /> I <br /> I <br /> I <br />' Advanced GeoEnvironmental,Inc <br />
