Under Air Sparging Treatment, GZA proposes that the air sparging sequence be changed. There <br /> is no mention of incorporating newly-installed air sparge well AS-7 into the sequence, nor is AS-7 <br /> included in Figure 2 of the Work Plan. Since I do not have a report of the well installations (VEW-3 <br /> through VEW-6 and AS-7), I was wondering if AS-7 was installed, and if so, why AS-7 was not <br /> included in the proposal. <br /> 2. Under Groundwater Monitoring, GZA is proposing that depth-to-water measurements be <br /> collected from various wells each quarter. Were these wells selected based on the concern of <br /> mounding taking place? <br /> Your assistance is greatly appreciated. <br /> Vicki McCartney, Senior REHS <br /> San Joaquin County <br /> Environmental Health Department <br /> 1868 East Hazelton Avenue <br /> Stockton, California 95205 <br /> Phone: (209)468-9852 <br /> Email: vmccartney(a sicehd.com <br /> u <br /> e, o• <br /> i. <br /> 11/18/2014 <br />
