Instead <br /> of over-drilling the wells, as approved by letter dated 27 February 2014 from San Joaquin County Environmental <br /> Health Department(EHD), Stantec°requests"pressure grouting the wells to the surface and remove the well <br /> boxes with hand tools.' <br /> The EHD approves the destruction of MW-2, MW-3 and MW-4 by pressure grouting with the following conditions: <br /> . Apply twenty-five pounds per square inch (psi) of liquid-grout pressure for a minimum of ten minutes at <br /> each well; <br /> . After applying the pressure, remove the well box and hand dig down to three feet below surface grade <br /> (bsg); cut off the casing at two-and-a-half feet bsg and grout the hole to near surface with neat-cement <br /> grout. The hole need not be a foot larger in diameter than the originally drilled hole; the hole just needs to <br /> be large enough to be able to reach down and cut off the casing a half-foot above the bottom of the hole <br /> 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: vmccartnevCcDsicehd.com <br /> I <br /> 5/9/2014 <br />
