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 />10
