A set of trenches at the southwest boundary <br />of the property (south cell T46, T48, T50, T58 and T59 and north cell T64, T65, T70) <br />demonstrated a differing thickness (topology) of the potentially buried waste. The waste <br />strata over native soil ranged from 18 inches at trench T46 to 10 feet deep at trench T58 <br />and to 13 feet deep at trench T65. <br />Remediation at this location involved the use of the excavator or backhoe, which <br />trenched down to native soil beneath any waste discovered (the current soil cap was <br />segregated). <br />Excavations removed the waste and adequately defined the horizontal and vertical <br />extent of the potentially buried waste, on the property to the west. Excavation was <br />required to depth of 13 feet at some locations, through the use of an excavator through <br />the encountered the waste glass and near native soil. <br />Approximately two waste cells of 2,000 square feet of area each (30 to 35 feet north to <br />soil and 65-70 feet east to west) had demonstrated some waste glass and debris, with a <br />variable thickness. Removal of the waste from the site (PENDING) to a Class II landfill <br />is proposed. <br />Advanced GeoEnvironmental, Inc. <br />
