KLEINFELDER <br />areas of the site due to degradation of vegetation in the lime. Soil was not excavated at depths <br />greater than 20. <br />Groundwater was encountered at depths of about 6 to 8 feet bgs. <br />One soil and two groundwater samples were collected from Site B per the request of Robert <br />McCollum from the PHS/EHD. The groundwater samples, CSW (6/16/99 and 6/20/99) were <br />taken from a disposable pre -cleaned bailer. The second groundwater sample collected on <br />6/20/99 was for metal analyses only. This groundwater sample was filtered and preserved in the <br />field prior to the metal analyses. The soil sample was collected just below the slaked lime and <br />above groundwater at an approximate depth of 10 feet bgs. The soil sample CS7 was sampled by <br />hand using a clean stainless steel tube pushed into the soil. Mr. McCollum requested that the <br />single soil sample CS7 and the groundwater samples CSW (6/16/99 and 6/20/99) should be <br />submitted for the analytes listed in Chapter 5 of this report. <br />4.1.2 Excavation of Disposal Site C <br />Site C was an irregular oval-shaped excavation approximately 250 feet long and up to 150 feet <br />wide by an average of 10 feet deep. Approximately 10,000 cubic yards of soil/debris was <br />removed. Debris included sheet metal. concrete, culvert piping, bricks, wire and wood. Mr. Rod <br />Getty from DSS estimated that debris at this location was approximately 25 percent by volume. <br />Concrete was estimated to he about 70 percent of the debris material. <br />Soils encountered included clayey silt and silty sand. No discolored soil or unusual odors were <br />noted during excavation activities. <br />Groundwater was encountered at depths of about 6 to 9 feet bgs. <br />A total of six soil samples labeled CS 1 through CS6 were collected from Site C. Groundwater <br />samples were not requested by Robert McCollum at this location. Groundwater seeped into this <br />excavation slowly and generally was not present as free water while excavating. Additionally, <br />for production and safety reasons backfilling and compaction was conducted during excavation <br />Lactivities. Six excavation bottom samples were collected at depth ranging from six to twelve feet <br />bgs. (see Plate 3). The soil samples were collected near the teeth of the excavator bucket. The <br />soil samples were collected by hand using a clean stainless steel tube pushed into the soil. Mr. <br />McCollum requested soil samples CSI and CS4 be analyzed for selected analytes listed in <br />Chapter 5 of this report. <br />ILI <br />20-3978-03.W36/2019766 Page 10 of 20 <br />© 1999.
