The boring will be drilled near wells MW-5A, B, and C. <br /> Wells MW-5B and C are the wells were are constructing next week. The attached map shows the location of the <br /> shallow wells we just installed and well MW-5A. <br /> The boring will be drilled using the sonic drilling equipment—dual rod drilling system with a 6-inch outer rod and a <br /> 4.5-inch inner rod or core barrel. The boring will be drilled to depth of approximately 30 ft and soil samples will be <br /> collected continuously during drilling. The boring will not be extended into groundwater, which is at a depth of <br /> approximately 35 ft. <br /> The boring will be backfilled using neat cement grout. <br /> Let me know if you have any questions or need further information. Thanks for your help. <br /> 8/27/2010 <br />
