IV. Conclusions <br /> The following conclusions and observations are provided: <br /> • Four groundwater monitoring wells were located, properly repaired, and <br /> redeveloped at MSC site at the Port of Stockton. <br /> • The wells were found to still be serviceable and were repaired to secure <br /> the surface casing access and redeveloped in anticipation of future <br /> sampling and analysis of representative ground water samples. <br /> • Monitoring Well MW-3 was the only well that appeared to have a sand- <br /> pumping problem. The cause of that problem is unclear, but it is <br /> suspected to be related to possible flowing conditions upon well <br /> installation that resulted in insufficient sand pack around the lowermost <br /> portion of slotted interval. In our opinion, this is a minor problem and the <br /> well should be adequate for sampling. <br /> • . MSC would like to close these wells in place in the near future, by filing a <br /> well destruction permit with the San Joaquin County EHD, upon <br /> conducting a one time ground water sampling as a cooperating party as <br /> was requested by the San Joaquin County EHD and the CVRWQCB. <br /> • <br /> 10 <br />
