KLEINFELDER <br /> 7. The remaining annular space was filled with cement/bentonite grout, <br /> introduced through a tremie pipe to the ground surface. <br /> 8. The well was secured in a locking standpipe. <br /> The well construction details are shown on Plate 4. <br /> Monitoring Well Development <br /> The well was developed on September 26, 1988, by air-lifting to repair damage to the <br /> formation caused by drilling. The sediment-laden water was purged from the well until the <br /> discharge ran relatively clear of fines. Approximately ten well volumes of water were <br /> removed from the monitoring well. <br /> To reduce the potential for introducing contamination, the developing equipment was <br /> steam cleaned prior to use in the monitoring well. Water produced during development <br /> was containerized in a 55-gallon drum. <br /> Sampling <br /> The aquifer was allowed to equilibrate for approximately 48 hours after development. The <br /> well was purged and sampled on September 2 , 1988. <br /> Purging was performed with a QED airlift pump. During the purging of the well, field <br /> parameters (pH, conductivity, and temperature) was monitored. The purge logs are <br /> included in Appendix A. The well was sampled with a teflon bailer after field parameters <br /> stabilized and five well-volumes of water were removed from the well. The sample was <br /> collected in appropriate sterile and preserved containers supplied by the analytical <br /> laboratory. The sample containers were immediately sealed, labeled, and placed in an iced <br /> cooler. The sample was then delivered under chain-of-custody to Chemwest Analytical <br /> Laboratories for analysis of- <br /> 0 Volatile Organic Compounds by EPA Methods 601 and 602 <br /> o Total Petroleum Hydrocarbons by EPA Method 418.1 <br /> o Metals by ICAP <br /> 137-88-1663 1 <br />
