i <br /> 18 June 2001 <br /> AGE-NC Project No 99-0559 <br /> IPage 2 of 5 <br /> I Temperature,pH and conductivity were measured for stabilization at regular purge-volume Intervals <br /> using an Oakton water analyzer Field data and logs are Included with Appendix A Purged ground <br /> water was containerized in 55-gallon drums and was stored on-site in an area lacking general public <br /> Iaccess <br /> I2 2 GROUND WATER PURGING AND SAMPLING <br /> Ground water samples were collected from the purged wells utilizing new, disposable polyethylene <br /> bailers and four 40-m1 EPA-approved volatile organic analysis (VOA) vials containing 0 5 ml 18% <br /> hydrochloric acid as a preservative Care was taken to ensure that visible air bubbles were not present <br /> in the vials after filling and capping Ground water sample containers were labeled with the well <br /> designation, date, time, and sampler's initials <br /> 2 3 ANALYSIS OF GROUND WATER SAMPLES <br />( � Each ground water sample was logged on a chain-of-custody form,placed in a chilled container and <br /> transported to McCampbell Analytical Inc (MAI), for analysis The ground water samples were <br /> analyzed for the following <br /> I0 Total petroleum hydrocarbons quantified as gasoline (TPH-g) in accordance with EPA <br /> Method 8015 Modified, <br /> • Volatile aromatics-benzene,toluene, ethylbenzene and xylene(BTEX) *ith methyl tertiary- <br /> butyl ether (MTBE) in accordance with EPA Method 8020, and <br /> I0 Fuel additives, including tertiary butanol (TBA), di-isopropyl ether (DIPE), ethyl tert-butyl <br /> ether (ETBE) and tert-amyl methyl ether (TAME), MTBE, methanol, ethanol, ethyl- <br />( dibromide (EDB) and 1,2-dichloroethane (1,2-DCA) in accordance with EPA Method 8260 <br /> Modified <br /> I24 FREE PRODUCT REMOVAL <br /> During the quarter, free-product product was recovered using a passive skimmer deployed on well <br /> MW-2 After removal, the water and free product were stored on-site in 55-gallon DOT H-17 <br /> storage drums The removal was performed in a accordance with California Underground Storage <br /> ITank Regulations, Article 5, Section 2655 <br /> i <br /> Advanced GeoEnvironmentul,Inc <br /> I <br />
