QUARTERLY GROUND WATER MONITORING- SECOND QUARTER 2003 <br /> On 25 April 2003,ground water monitoring was performed at the site The ground water monitoring <br /> event was performed in accordance with guidelines established by the EHD and RWQCB and were <br /> performed in accordance with the approved Preliminary Site Assessment Work Plan, dated <br /> 15 April 1999 <br /> • 3 1 GROUND WATER MONITORING PROCEDURES <br /> The ground water monitoring activities included measurement of ground water levels and collection <br /> of ground water samples from each of the monitoring wells MW-1 through MW-5 (Table 2) <br /> 31 1 Ground Water Depth Measurement and Purging <br /> During the April sampling event a Solinst water level meter was used to measure the depth to ground <br /> water in the monitoring wells relative to the tops of the well casings After the depth-to-ground water <br /> measurements were collected, casing water in the monitoring wells was evacuated using new, <br /> 1 dedicated,disposable polyethylene bailers Approximately nine gallons ofwater were removed from <br /> each of the monitoring wells, equivalent to three casing-water volumes per well Temperature, pH <br /> and conductivity of the purged water were measured at regular purge-volume intervals with an <br /> Oakton water analyzer Momtonng well field logs are included in Appendix C Purge water <br /> generated from the site monitoring wells was contained on-site in appropriately labeled 55-gallon <br /> drums <br /> 1 <br /> F <br /> 1 <br /> 1 Advanced GeoEnvironmentai,Inc <br />
