' 27 June 2002 <br /> AGE-NC Project No 98-0448 <br />' Page 5 of 8 <br />' Tables 3 and 4 The laboratory reports(McCampbell Analytical Inc I D 90804 through 90808) and <br /> chain-of-custody forms are presented in Appendix C <br />' 43 RESULTS OF VAPOR EXTRACTION <br />' Between 01 January 2002 and 31 March 2002, the SVE and IAS remediation systems were <br /> continuously operational for 2,160 hours, the SVE and IAS systems have totaled 8,152 hours of <br /> operation since initiation on 16 April 2001 (Table 6) During the first quarter 2002 operational <br /> I period, SVE Inlet flow rates ranged from 28 to 39 cubic feet per minute (cfin), differential pressures <br /> ranged between 0 25 and 0 50 Inches of water, and Induced vacuum between 60 and 70 Inches of <br /> water Utilizing a photo Ionization meter (PID), SVE inlet hydrocarbon concentrations were <br /> measured between 3 3 and 7 8 parts per million (ppm), however a general concentration trend was <br /> not established from the PID field measurements Field measurements are summarized In Table 6 <br /> 4 4 ANALYTICAL RESULTS OF SOIL-GAS VAPOR SAMPLES <br /> 10 SVE air flow samples were collected on 10 January, 21 February and l I March 2002 TPH-g was <br /> detected from all influent SVE air flow samples at concentrations as high as 480,ug/l TPH-g was <br />' detected in the 11 March 2002 effluent SVE air flow sample at a concentration of 300,ug/l,but not <br /> detected In effluent samples collected in January and February 2002 <br /> IBTEX compounds were detected in all Influent SVE air flow samples at concentrations as high as <br /> ' 76 xu,Wl(xylene, 11 March 2002) Benzene was only detected In the March 2002 Influent and effluent <br /> SVE air flow samples at concentrations of 2 8,ug/l and 2 4,ug/1, respectively Analytical results of <br /> SVE air flow samples are summarized In Table 5 The laboratory reports (McCampbell Analytical ' <br /> Laboratory I D Nos 88125-26,91108-09 and 0203203-001 and 002 and chain-of-custody forms are <br /> presented in Appendix D A plot of influent TPH-g SVE air flow concentrations versus time Is In <br /> IAppendix E <br /> 4 5 MASS CALCULATION OF RECOVERED PRODUCT <br /> The hydrocarbon mass removed during the SVE operating period was calculated using the following <br /> equation M =C•Q•t <br /> where M= cumulative mass recovered (kg) <br /> IC =vapor concentration (kg/m ) , <br /> IAdvanced GeoEnvironmental,Inc <br />
