31 October 2063 <br /> AGE-NC Project No 95-0137 <br /> Page 3 of 6 <br />' After recording water level measurements, disposable plastic bailers were used to purge the wells <br /> of standing water Approximately 3 to 5 5 gallons of water(a minimum of 3 casing water-volumes <br /> per well)were removed from MW-1 through MW-5,well MW-2 was purged dry after three gallons <br />' of water were removed �5arnrl6� tv�.r� 12-a <br /> Ground water temperature,pH and conductivity were measured at regular intervals during purging <br /> using an Oakton water analyzer Purged ground water was containerized in properly labeled <br /> DOT-approved model 17H 55-gallon drums and'was stored on-site Field sheets and data are <br /> included in Appendix A <br /> 2 2 2 Collection and Analysis of Ground Water Samples <br /> Water to samples were collected from the purged wells using new disposable plastic bailers after <br />' allowing the wells to achieve a minimum 80%recovery of the pre-purge water volume Each sample <br /> was transferred into three 40-m1 EPA-approved volatile organic analysis (VOA) vials and into one <br /> 1-liter amber bottle Samples were properly labeled, stored in a chilled container and transported <br />' . under chain-of-custody to Cal Tech Environmental Laboratories (CTEL) a California Department <br /> of Health Services (DHS)-certified laboratory in Paramount Each sample was analyzed. for <br /> • Total petroleum hydrocarbons quantified as gasoline, diesel and motor oil (TPH-g,TPH-d <br />' and TPH-mo) in accordance with EPA Method 8015 Modified, and <br /> • BTEX compounds and the oxygenating fuel additives methyl tertiary butyl ether(MTBE), <br />' tertiarybutyl alcohol(TBA),di-isopropyl ether(DIPE),ethyl tertiary butyl ether(ETBE)and <br /> tertiary amyl methyl ether(TAME), ethylene dibromide(EDB)and 1,2 dichloroethane(1,2- <br /> DCA) in accordance with EPA Methods 8260 <br /> 1 <br />' 3.0. FINDINGS <br /> From field and laboratory data collected at the SVE remediation system between May to <br />' September 2003, AGE determined the average TPH-g concentration, the average flow rate and <br /> calculated the approximate mass of hydrocarbons removed Ground water elevation, flow direction <br /> and gradient were determined from field data collected on 14 and 16 May 2003, the contaminant <br />' impact to ground water was quantified from the ground water laboratory data <br /> R <br /> 3 1 SOIL VAPOR EXTRACTION <br /> • The SVE unit was operated continuously during the period between 07 May to 10-September 2003 <br /> The unit operated at an average extraction flow rate of 135 cubic feet per minute (cfm) An induced <br /> Advanced GeoEnvironmental,Inc <br />
