Instead of over-drilling the wells, as approved by letter dated 27 February 2014 from San <br /> Joaquin County Environmental Health Department(EHD), Stantec requests"pressure grouting the wells to <br /> the surface and remove the well boxes with hand tools.' <br /> The EHD approves the destruction of MW-2, MW-3 and MW-4 by pressure grouting with the following <br /> conditions: <br /> . Apply twenty-five pounds per square inch (psi) of liquid-grout pressure for a minimum of ten <br /> minutes at each well; <br /> • After applying the pressure, remove the wellboxand hand dig down to three feet below surface <br /> grade (bsg); cut off the casing at two-and-a-half feet bsg and grout the hole to near surface with <br /> neat-cement grout. The hole need not be a foot larger in diameter than the originally drilled hole; the <br /> hole just needs to be-large enough to be able to reach down and cut off the casing a half-foot above <br /> the bottom of the hole and allow grout to surround the casing at total depth. <br /> Please contact me if you have any questions. <br /> Thank you, Amanda. <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: vmccartneV(o_sicehd.com <br /> 5/19/2014 <br />
