The former green house was demolished and buried <br />on-site. STS recommended that a series of test pits also be excavated in these areas. <br /> <br />Zappa & Son Excavating Company of Fridley, Minnesota was contracted to excavate a series of <br />test pits within the Dale-Western site to identify potential fill materials within the three areas <br />identified as disposal locations. The locations of the test pits were randomly selected by STS field <br />personnel to provide a representative profile of the fill materials. Test pits were perlormed within <br />the general area of the disposal sites, however no survey of test pit locations or elevations were <br />performed. The pits were excavated to below the debris into fill or native soils. Soil samples were <br />collected for laboratory analysis from the base of the test pits based on the findings within the test <br />pits. The test pits were excavated on March 3, 1994. Snow cover was present at the time of the <br />excavation. The locations of the three areas are identified as Areas 8 (Area A), 14 (Area B) and 19 <br />(Area C) on Figure 3 in the Appendix. <br /> <br />A total of 24 test pits were dug within the three areas. Seven test pits were performed in the <br />greenhouse area (Area 8), one within the street sweepings area (Area 14) and sixteen within the <br />central dump site (Area 19). <br /> <br />Debris encountered in test pits A-3 and A-5 within Area 8 (Area A) consisted of concrete, bricks, <br />glass, wood and slag. Fill materials encountered in test pit B-1 within Area 14 (Area B) consisted <br />of street sweepings. No debris was encountered in test pit B-1. Debris was encountered in test <br />pits C-2, C-4, C-5, C-7, C-8, C-9, C-13 and C-16 in Area 19 (Area C). The debris was primarily <br />concrete, glass, metal, metal containers, tires, rubber hosing, plastics, wood and brick. One <br />crushed 55-gallon drum was observed in pit C-3. <br /> <br />- 2 - <br />
