Probe boring B 1 was soil-sampled <br /> continuously to 24 feet below surface grade(bsg)using a four-foot core barrel. Soil probe boring B 1 <br /> was advanced vertically to a depth of 73 feet bsg. A ground water sample was not collected from <br /> boring B1 due to equipment failure. Soil probe boring B2 was advanced utilizing a truck-mounted <br /> SD-1 equipped with 1.125-inch diameter probe rods using "direct push" technology. Probe boring <br /> B2 was advanced to obtain a ground water sample. Soil probe boring B2 was advanced vertically to <br /> a depth of 74 feet bsg. <br /> Advanced GeoEnvironmental,Inc. <br />
