03 June 2002 <br /> ` AGE-NC Project No. 97-0360 <br /> Page 3 of 7 <br /> • The fuel additives di-isopropyl ether (DIPE), ethyl tertiary-butyl ether (ETBE), MTBE, <br /> tertiary-amyl methyl ether(TAME),tertiary butanol(TBA), 1,2-dichloroethane(1,2-DCA) <br /> and ethylene dibromide (EDB) in accordance with EPA Method 8260 Modified. <br /> 2.5. MONITORING WELL DEVELOPMENT <br /> On 08 February 2002,wells MW 1 through MW5 and EW 1 were developed utilizing a stainless steel <br /> hand bailer and a two-stage submersible pump.Ground water was purged from each monitoring well <br /> until ground water was visually sediment free;approximately 20 gallons ofwater were removed from <br /> wells MW 1 through MW5 and approximately 55 gallons of water were removed from well EW L <br /> Purged ground water was containerized in properly labeled DOT-approved model 17H 55-gallon <br /> ` drums and was stored on-site. Field sheets and data are included in Appendix B. <br /> 2.6. MONITORING WELL PURGE PROCEDURES <br /> Ground water sampling ofwells MW 1 through MW5 and EW 1 was.conducted on 11 February 2002. <br /> For the sampling event, a Solinst water level meter was used to measure the depth to ground water <br /> in the wells relative to the tops of the well casings. The ground water elevations and gradient were <br /> determined from these data(Table 1). <br /> After recording water level measurements, disposable plastic bailers were used to purge wells <br /> MW 1 through MW5 and EW1 of standing water. Approximately 6 gallons of water(a minimum of <br /> -� <br /> 3 casing water-volumes per well)were removed from MW 1,MW3,MW4 and MW`5 approximately <br /> 14 gallons.of water were removed from MW2;and approximately 60 gallons ofwater were removed <br /> from EW 1. Ground water temperature, pH and conductivity were measured at regular intervals <br /> during purging using an Oakton water analyzer.Purged ground water was containerized in properly <br /> labeled DOT-approved model 17H 55-gallon drums and was stored on-site.Field sheets and data are <br /> included in Appendix C. <br /> .:; 2.7. COLLECTION OF GROUND WATER SAMPLES <br /> Water samples were collected from the purged wells using new disposable plastic bailers.Each water <br /> sample was transferred into three 40-m1 VOA vials containing 0.5 ml 18% hydrochloric acid as a <br /> sample preservative and into one 1-liter amber bottle without sample preservative.After collection, <br /> the samples were properly labeled, placed in a chilled container and transported under chain-of- <br /> custody to CTEL. The sampleswere analyzed for: <br /> --{ Advanced GcoEnvironmental,Inc. <br /> '.J <br />
