Since these wells appear to be so close (two to three feet)to underground <br /> utilities, the mushroom cap may be omitted. <br /> 1' <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)46879852 <br /> Email: vmccartneyCaD_sjcehd.com <br /> i <br /> From: Magee, Amanda [mailto:Amanda.Magee@stantec.com] <br /> Sent: Monday, March 24;2014 1:23 PM <br /> To: Vicki McCartney [EH] <br /> Cc: Manning, Danielle; Lichtenberger, Deborah <br /> Subject: 7-11 #20632, 4627 DaVind Drive,;Stockton <br /> Hi Vicki, <br /> Thank you for taking the time to chat with me regarding the well destruction at the above <br /> referenced site. As I mentioned,,monitoring well MW-2 and remediation well SPV-2 are both <br /> located close to underground utilities, as shown in the attached pictures. These wells are not in <br /> the source area, and recent groundwater samples from MW-2 have only contained low <br /> concentrations of WK. 1.have.attached our soil and groundwater tables as well..Stantec <br /> proposes to pressure grout these wells to the surface, remove the well box, and finish the surface <br /> with asphalt to match the existing driveway. Please let me-know if this is an acceptable proposal: <br /> Thank you, <br /> Amanda Magee, P.G. <br /> Associate Geologist <br /> Stantec <br /> 3017 Kilgore Road,Suite 100 Rancho Cordova CA 95670-6150 <br /> Phone: (916) 384-0743 <br /> Cell: (916) 747-3181.. <br /> amanda.magee@stantec.com <br /> 3/24/2014 <br />
