We will perform a total of eightborings on the proposed site. The borings will be extended to depths on the order of feet below existing grades. The borings will be evenly spaced throughout the site. The borings will be drilled utilizing 3. 25-inch hollow stem, continuous flight augers. The borings will be performed utilizing an atv-mounted drill rig and will generate an approximately 6-inch annulus. Sampling will be conducted using a 2-inch o. D., split-barrel sampler driven into the soil a distance of 18 or 24 inches by a 140-pound hammer falling inches. The samples will be placed in glass jars for geotechnical classification. Additional eight infitration test will be performed at a max depth of 10ft. The purpose of the phase ii environmental site assessment is to evaluate the subsurface environment, where accessible, to determine if the past use of the property has impacted the subsurface soils and groundwater.
