grouted to the surface with Quikcrete Cementsee Appendix .A <br /> ( pp } <br /> 3.4 Monitoring Well Sampling <br /> On November 19, the water level in the well was measured relative to the top of the casing <br /> using a Solonist water level meter. The depth to groundwater was 8.19 feet. A notch was <br /> cut on the north side of the top of the casing to use as a reference for future measurements <br /> and surveying, if necessary. <br /> After the water level was measured, a stainless steel bailer was used to remove sediments <br /> from the bottom of the well. After removal of excess sediments, a 3-stage purge pump was <br /> used to surge and purge the well. Approximately 25 gallons of water were removed from <br /> the well. Temperature, pH and conductivity were measured at one-gallon intervals for the <br /> first 9 gallons (see Table 1). The purge water was stored on-site in a 55-gallon drum. <br /> A water sample was collected using a new disposable plastic bailer and stored in 40-m1 EPA <br /> vials. The vials were placed in a chilled container and transported under chain-of-custody <br /> to McCampbell Analytical in Pacheco, California. <br /> LTABLE 1 <br /> GROUNDWATER STABILIZATION DATA <br /> November 19, 1.993 <br /> Volume <br /> Temperature Conductivity <br /> (gallons) pH (°F) (µS/cm x 100) <br /> ::1 <br /> MW-1 <br /> 0 7.3 63.3 14.62 <br /> 1 <br /> 7.3 64.8 15.59 <br /> 2 7.4 64.4 14.43 <br /> 3 7.2 63.7 12.60 <br /> 4 3.7 63.6 12.74 <br /> 5 3.0 62.7 14.07 <br /> 6 2.9 62.1 14.26 <br /> 7 3.7 60.9 12.27 <br /> 8 2.9 62.3 12.73 <br /> 9 2.8 64.8 13.62 <br /> Oolo�ial Audis 5-i-,[nc <br /> Road Props tym-1691181 B-S <br />
