AGE-NC Project No 95-0130 <br /> Page 3 of 3 <br />' 3) 07 November 2005 - 07 December 2005 <br /> The average analytical TPH-g concentration for this time interval was determined to be 1,310 µg/l <br />' (11-07-05= 720 gg/l and 12-07-05 = 1,900 gg/1, avg = 1,310 gg/1) The average flow rate was <br /> calculated at 2 90 inches of water or approximately 90 cubic feet per minute (nomograph), the <br /> operational period was equal to 425 hours of running time (Table 6) <br />' TPH- (total petroleum hydrocarbons quantified asgasoline) <br />' C = 1,310 lig/1 =0 001310 kg/m' <br /> Q = 2 90 inches water = 90 ft/mm <br />' t=425 hours (18 days) <br /> Converting Q to m3/hour yields <br />' Q = (90 ft'/mm) • (60 min/hour) • (0 0283168m'/ffi)= 152 91 m'/hour <br />' • M= C • Q • t= (0 001310 kg/m') • (152 91 m3/hour) • (425 hours)=85.13 kg of TPH-g <br /> Converting kg of TPH-g to pounds of TPH-g yields <br /> 85 13 kg of TPH-g • 2 2046 lbs of TPH-g/kg of TPH-g= 187.7 lbs of TPH-g <br />' Converting pounds of gasoline to gallons of gasoline yields <br /> 187 7 lbs of gas • 0 16 gal of gas/lbs of gas = 30 gallons of gasoline <br /> I <br /> I <br /> I <br /> i <br /> Advanced GeoEnvironmentsl,Inc <br /> I <br />
