The location <br /> of the proposed groundwater monitoring wells appear to be well placed <br /> based on the results of the hydropunch data. Based on the results of the <br /> proposed wells, additional wells may need to be installed in the future. <br /> The installation of the proposed vapor extraction test wells is warranted <br /> at this time. As noted in the workplan, the final and specific location and <br /> construction of these wells must be based on the lithological conditions <br /> observed during the field work. Based on the use of vapor extraction <br /> technology at a nearby site with similar conditions, several limited screen <br /> length intervals, possibly in a nested borehole, may be appropriate for <br /> this site also and should be considered. A vapor extraction test should <br /> be scheduled and completed within two weeks after this phase of field <br /> work. <br /> Therefore, based on the above discussion, please proceed with the <br /> work as proposed in the workplan addendum. This work should be <br /> completed and a Corrective Action Plan submitted to this office by <br /> February 5, 1996. <br /> A Division of San Joaquin County Health Care Services <br />
