' 22 April 2002 <br /> AGE-NC Project No 98-0448 <br />' Page 3 of 8 <br />' air compressor to infect air beneath the water table Operation and design of the SVE and IAS <br /> systems for the site were described in Remedial Action Work Plan dated 07 July 2000,prepared by <br /> AGE, and approved by the FHS-EHD by letter dated 14 July 2000 <br /> 1 <br /> 3 1 SOIL VAPOR EXTRACTION/IN-SITU AIR SPARGE SYSTEM PROCEDURES <br />' The SVE system utilizes a model Fuji,3-horsepower regenerative vacuum blower and two 80-gallon <br /> carbon canisters to extract and adsorb hydrocarbon vapor from the subsurface Two-inch diameter, <br />' schedule 80 PVC piping was installed underground from wells VW-1 through VW-5 to the inlet of <br /> the regenerative vacuum blower, the outlet from the vacuum blower was routed through two <br /> sequential 55-gallon carbon canisters A Magnehelic vacuum gauge was attached to the inlet of the <br />' blower, air flow was monitored at the inlet using a Dwyer DS-200 flow sensor A flow rate was <br /> determined from the measured differential pressure and the piping diameter using a nomograph <br /> (Appendix B) <br /> In order to monitor the efficiency of hydrocarbon destruction, 1)the SVE air flow of the influent and <br /> • effluent streams was monitored routinely for the presence of organic vapor using an organic vapor <br /> analyzer(OVA)equipped with a photo-ionization detector(PID Thermo Environmental 580A, 10 0 <br /> eV, calibrated to isobutylene) and 2) influent and effluent air flow vapor stream samples were <br />' collected from sampling ports installed upstream(influent)and downstream(effluent)of the vacuum <br /> blower and analyzed Field measurements were recorded at regular intervals and are summarized in <br /> Table 6 <br /> 3 2 COLLECTION AND ANALYSIS OF VAPOR EXTRACTION AIR FLOW SAMPLES <br />' A total of six extracted air flow vapor samples were collected on 15 October, 07 November and 13 <br /> December 2001 from the influent and effluent streams of the regenerative vacuum blower unit to <br />' measure concentrations of hydrocarbon vapor The samples were collected in-Tedlar bags using a <br /> hand air-vacuum pump <br />' Following sample collection,the samples were placed in a covered container and transported under <br /> chain-of-custody to either McCampbell Analytical Laboratory(MAL)in Pacheco, California Each <br /> sample was analyzed within 72 hours of collection for TPH-g and BTEX in accordance with EPA <br />' Methods 5030/8015 Modified and 8020 <br /> 1 <br />' Advanced GeoEnvzronmental,Inc <br /> 1 <br />
