<br /> Notes
<br /> System consists of one regenerative blower with 5 hp motor and two 2000 Ib GAC units in series (Unit 1 and Unit 2)
<br /> System start-up was conducted by Aegis Environmental (now Fugro West, Inc ) on 6/23/93 System was previously operated by Resna Industries
<br /> avg. = average of three sets of measurements collected at 15 minute intervals
<br /> GAC = granular activated carbon
<br /> Airflow measured between Carbon Unit 1 and Unit 2 except on 7111/94 and 8/23/94 Airflow measured at the vent well manifold an 7111/94 and 8/23/94
<br /> Influent = prior to Unit 1/sod vent blower discharge
<br /> Effluent = Unit 2 (atmospheric discharge)
<br /> TPH = total petroleum hydrocarbons as gasoline
<br /> ppmv = parts per million by volume
<br /> FID-field measurement from flame ionization detector calibrated to hexane(Model- Century OVA 128 by Foxboro Company)
<br /> LAB = laboratory analysts
<br /> ND = not detected at indicated reporting limit
<br /> " ACFM = actual cubic feet per minute "
<br /> SCFM = standard cubic feet per minute (14 7 PSI and 70 deg F)
<br /> PSI = pouncWsquare inch
<br /> See attached extraction rate calculation
<br /> Cumulative extraction is calculated by averaging extraction rates for consecutive sampling events and summing up previous total
<br /> *Cumulative TPH extraction calculations do not include TPH extraction between 1/7-1/27 & 718-7/11/94 f
<br /> For cumulative TPH extraction calculation after 12/30/94, system operation hours are esttmated based on field observations
