Also, the work plan <br /> mentions that the ten direct-push borings, advanced to approximately twenty-five feet bgs, will be grouted using a <br /> tremie pipe; however, there is no mention of using a tremie pipe when grouting the other proposed deep borings, <br /> monitoring wells, and one shallow aquifer test well. I would appreciate if you could have these matters clarified <br /> prior to your approval of this work plan. Thank you, Amy. <br /> Vicki McCartney, Senior REHS <br /> San Joaquin County <br /> Environmental Health Department <br /> 600 East Main Street <br /> Stockton, California 95202 <br /> Phone: (209)468-9852 <br /> Fax: (209)468-3433 <br /> Email: vniccartne�7ta'sjcehd.com <br /> 7/27/2009 <br />
