We will perform a total of four soil borings on the proposed site. The borings will be advanced to a depth of feet below existing site grades. The borings will be located within the bounds of the private property. The borings will be drilled utilizing 3. 25-inch hollow stem, continuous flight augers. The borings will be performed utilizing a truck-mounted drill rig and will generate an approximate 6-inch annulus. After geotechnical exploration is completed, the borings will be backfilled, in accordance with doee requirements, with bentonite slurry, which has a consistency of two pounds bentonite powder to one gallon water.

We will perform four soil borings on the proposed site. The soil borings will each be advanced to a depth of feet. Additionally, one soil boring and three infiltration auger probes will be performed on the proposed site and will be advanced to depths of feet and 8 feet respectively. The borings/auger probes will be located within the bounds of the property. The borings/auger probes will be drilled utilizing 3. 25-inch hollow stem, continuous flight augers. The borings/auger probes will be performed utilizing an atv and/or truck-mounted drill rig and will generate an approximate 6-inch annulus. After geotechnical exploration is completed, the borings/auger probes will be backfilled with bentonite slurry, which has a consistency of two pounds bentonite powder to one gallon water. Borehole/auger probe abandonment will be performed by tremie-grouting via a positive-displacement pump from the bottom of the borehole/auger probe.
