MONITORING WELL DEVELOPMENT ACTIVITIES <br />`1 On 03 July 2000,monitoring well MW1 was developed utilizing a stainless steel hand bailer and a <br /> Grundfos pump. <br /> AMO Ground water was purged from the monitoring well until ground water was visually sediment free; <br /> approximately 35 gallons of water were removed from the.well. Purged ground water was <br /> containerized in properly labeled D.O.T.-approved model 17H 55-gallon drums and was stored on- <br /> site in an area lacking public access. The field sheet and data are included in Appendix B <br /> v 3.6. MONITORING WELL PURGE PROCEDURES <br /> Ground water sampling of MW 1- was conducted on 03 July 2000.For the sampling event,a Solinst <br /> "y water level meter was used to measure the depth to ground water in the well relative to the top of the <br /> well casing. The ground water elevation was determined from this data(Table-1). <br /> Lao After recording water level measurements,a disposable bailer was used to purge the monitoring well <br /> of standing water. Approximately 35 gallons of water (minimum of 3 casing-water volumes) was <br /> removed from the well. Ground water temperature,pH and conductivity were measured at regular <br /> `r intervals during purging using a Hydac water analyzer. The field sheet and data are included in <br /> Appendix B. Purged water was stored on-site in labeled, 55m-gallon DOT-approved drums. <br /> LW - <br /> Advanced GeoEnvironmental,Inc. <br /> r <br />
