Instead of <br /> destroying MW-4R by pressure grouting, please destroy MW-4R as follows: <br /> Insert an additional Schedule 40 casing at least eight-inches larger in diameter than the outside diameter of the present <br /> casing of MW-4R to total depth of fifteen feet below surface grade(bsg); if the pea gravel extends beyond fifteen feet bsg, <br /> then extend the casing to the total depth of the pea gravel. This should contain the pea gravel and prevent the pea gravel <br /> from entering the area around MW-41R. Drill out MW-4 as originally proposed and grout the borehole with near cement <br /> grout to the surface while removing the outer casing.. <br /> I have fieldwork today and will be leaving the office around 10:50 a.m. You can reach me on my cell phone at(209)481- <br /> 9257 if you have any questions. <br /> Thanks, 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(asicehd.com <br /> 1 I <br />
