The deep well will be drilled using a mud rotary drill rig. After the top 50 <br /> feet of alluvial deposits has been drilled using mud rotary rig, a steel <br /> conductor casing will then be set two feet into the aquitard. During the deep <br /> well drilling, samples will be collected at five foot intervals in the first <br /> aquifer. Samples will be collected continuously in both the first aquitard and <br /> deep aquifer into the second clay interval, terminating two feet into this <br /> aquitard. This clay layer is present at depths of 50 to 60 feet in the nearby <br /> Compressor Station water supply well. <br /> HSA drive samples and mud rotary pen samples of the unconsolidated <br /> material will be collected and archived at the intervals described above and at <br /> significant lithological changes. During the geologic logging of the well, the <br /> samples and cuttings will be examined and described using the USCS. <br /> Laboratory permeabilities, porosity, sieve analysis and moisture content <br /> analysis will be run for soil samples taken in the shallow and deep aquifer <br /> material, from each well. The deep well will be screened in the <br /> unconsolidated material of the deep aquifer (approximately 55 ft. to 65 ft.) <br /> and terminate in the second clay interval located at a projected depth of 65 to <br /> 70 feet below the surface. <br /> Z9PROP-PRA 19W 1574-p\dchvbleVpo-1574-I.dm <br /> 9 <br />
