r <br /> V <br /> The well was screened with 2-inch OD screw type slotted schedule 40 PVC casing from <br />' 70 feet to 45 feet below surface grade and cased from 45 feet to the surface with 2-inch blank <br /> casing The gravel pack interval extended from total depth to 42 feet, which was followed with <br />' bentonite from 42 feet to 39 feet and then was grouted to the surface The well was completed <br /> with a surface vault, properly cemented in place and completed with a heavy duty bolt down <br />' traffic cover Details of the lithology and the monitor well completion are on the boring logs <br /> in Appendix A. <br /> V&W Drilling, Inc., then moved and setup for the augenng and construction of monitor <br /> well MW-10. The boring was drilled to a total depth of 70 feet and groundwater was initially <br />' noted at a depth of 60 feet. Soil samples were obtained for laboratory analysis from 45 to 46 5, <br /> 50 to 51 5, 55 to 56 5, 60 to 61, 65 to 66 5, and 70 to 71 feet Field hydrocarbon <br /> measurements were detected with the PID, which had a maximum value of 8 ppm from the 65 <br /> to 66.5 foot interval A sweet odor was again noted in the soil from approximately 10 to 25 feet <br />' below the surface. The monitor well completion and lithology were similar to description of <br /> monitor well MW-11. <br />' On July 12, 1996, monitor well MW-3A was installed at the Canteen facility located at <br /> 1500 Shaw Road, which is adjacent to the U S Chemical facility The boring for monitor well <br /> MW-3A was drilled to a total depth of 67 feet Samples were obtained for laboratory analysis <br />' from 30 to 315, 35 to 36 5, 40 to 41 5, 45 to 46 5, 50 to 51 5, and 60 to 61 feet There were <br /> no field hydrocarbon readings above zero and groundwater was initially detected at a depth of <br /> 60 feet. Since the purpose of this monitor well was to determine if representative groundwater <br /> samples have been obtained in the past from monitor well MW-3, the screened interval for the <br /> well was approved in the field by Mr. Infurna A 20-foot screened interval 67 to 47 feet below <br /> the surface was chosen The remainder of monitor well completion was similar to the previous <br /> monitor wells For detailed descriptions of the lithology and monitor well completions refer to <br /> Appendix A <br /> 3 <br />
