I <br />' 21 November 2005 <br /> AGE-NC Project No 96-0263 <br />' Page 2 of 4 <br />' Each month, the oxygen reduction potential (redox or ORP) and dissolved oxygen (DO) <br /> concentration were measured from observation wells MW-1 through MW-11 ORP was measured <br /> with a Hanna Instruments' (HI)-9025 pH meter, DO was measured with a YSI-55 dissolved oxygen <br />' meter ORP and DO data collected during the Ozone infection pilot test is summarized in Table 1 <br /> 2 2 QUARTERLY GROUND WATER SAMPLING AND LABORATORY ANALYSIS <br /> During the pilot test,ground water samples were collected quarterly from observation wells MW-1, <br />' through MW-11 Groundwater samples were collected in June 2004,August 2004,November 2004 <br /> and March 2005 <br /> The collected ground water samples were properly labeled and transported in a chilled container <br /> under chain-of-custody to CalTech Environmental Laboratories (CTEL), a California Department <br /> of Health Services (DHS)-certified laboratory Each sample was analyzed for <br /> • <br /> Total petroleum hydrocarbons quantified as gasoline (TPH-g) in accordance with EPA <br /> Method 8015M, <br /> • BTEX compounds (benzene, toluene, ethylbenzene, and total xylenes) and fuel additives, <br /> including methyl tertiary-butyl ether(MTBE),di-isopropyl ether(DIPE),ethyl tertiary-butyl <br />' ether (ETBE), tertiary-amyl methyl ether (TAME), tertiary butanol (TBA), ethylene <br /> dibromide (EDB) and 1,2-dichloroethane (1,2-DCA) in accordance with EPA Method <br /> 826013, <br /> Ground water samples collected during June 2004 were reported in the AGE-prepared, Quarterly <br /> Report-Second Quarter 2004, dated 28 January 2005 Water samples collected during the August <br /> 2004 event were reported in the AGE-prepared, Quarterly Report - Third Quarter 2004, dated <br /> 10 February 2005 Water samples collected during the November 2004 event were reported in the <br /> AGE-prepared, Quarterly Report - Third Quarter 2004, dated 13 March 2005 and water samples <br /> collected during the March 2005 event were reported in the AGE-prepared,Quarterly Report-First <br /> Quarter 2005, dated 17 May 2005 <br /> 3.0 FINNDINGS <br /> Analytical results of ground water samples and field measurements conducted between 12 June 2004 <br /> and 09 March 2005 were used to evaluate the effectiveness of ozone infection as a remedial <br /> technology at the site <br /> Advanced GeoEnwonmental,Inc <br /> I <br />
