drilled with continuous-flight, hollow-stem auger equipment to depths <br /> of 50-1/2 and 40-1/2 feet, respectively. Disturbed and undisturbed <br /> soil samples were collected from these borings and permeability test <br /> wells (permeameters) were installed in each. <br /> Boring P-1, located in the northern portion of the site penetrated <br /> interlayered silts, clays, silty sands, and clayey sands to a depth of <br /> 25 feet. Below 25 feet, the boring encountered poorly to well -graded, <br /> dense clean sands. Such a thick deposit of clean sand is atypical for <br /> the site and was not discovered in any other borings on site. <br /> Boring P-2, located in the southern section of the site, penetrated <br /> interlayered silts and sandy silts, as well as very dense sands and <br /> silty sands to the entire depth. Thicknesses of layers ranged from <br /> 1-1/2 to 5 feet. Boring P-3 was drilled to explore intermediate <br /> depths and encountered primarily fine-grained soil to its total depth <br /> of 89 feet. <br /> Deep Borings G-1 , and G-2, and G-3 were drilled to obtain samples of <br /> ground water beneath the proposed landfill site and to characterize <br /> the intervening materials. Boring G-1 was drilled with air-rotary <br /> drilling equipment and extended to a total depth of 166-1/2 feet, <br /> encountering ground water at a depth of approximately 150 feet. <br /> Intervening deposits consisted of heterogenous interlaying silt, clay, <br /> and sand. Finer-grained deposits predominated (see Drawing 2) . <br /> Boring G-2 was drilled with mud-rotary rather than air-rotary drilling <br /> equipment due to borehole stability problems. The boring extended to <br /> a total depth of 156-1/2 feet, encountering ground water at a depth of <br /> approximately 148 feet. The boring encountered primarily fine-grained. <br /> soil in the upper 40 feet, sandy soils below 80 feet, and predominant- <br /> ly sandy clays and silty sands, with several gravelly layers, below <br /> 101 feet (see Drawing 2 and Appendix A) . <br /> PJ9 9390206.00D 7 <br />
