' Elks Lodge Property 1JeYty 0 Page 2 317 South Center Street Stockton, California August 9, 2001 Three (3) soil samples from each boring were collected at 1.5', 2.5', and 3.5'. The three (3) samples from each boring were composited into a single sample for laboratory analysis. 3.1 Drilling The soil borings were accomplished using a hand auger. All p u eqi ment was thoroughly cleaned before digging began, to prevent the introduction of contamination from off site, and between borings to prevent cross contamination. ' 3.2 Soil Sampling All soil sampling equipment was thoroughly cleaned before and between sampling to prevent cross contamination. Relatively undisturbed soil samples were taken between at 1.5', 2.5', and 3.5' in order to evaluate the subsurface ' materials. The soil samples were taken using a Drive Shoe Spoon sampler with a brass liner. ' The sampler was driven continuously by a hand driver. The laboratory samples did not have head space and were immediately sealed in their liners using Teflon lined plastic caps. The samples were labeled and placed in an ice chest cooled ' with Blue Ice®. They were then delivered to the State-certified laboratory, Geo- Analytical Laboratories, Inc., in Modesto, California. ' Soil samples collected were analyzed using EPA method 6010B for Lead and samples from HB-3 and HB-9 were further analyzed for soluable total lead ' content using EPA method STLC6010B. The soils at the locations of sampling were all sandy silts, dense, and dry from 0 to 2.0 feet. From 2.0 to 3.5' the soil was clay and moist. Chain of Custody records were maintained at all times (Appendix A). 3.3 Analytical Results The soil samples collected at HB-1 and HB-2 indicate, after laboratory analysis, ' that significant lead contamination exists in the soil. Table 1 below summarizes the levels present in each soil sample. Laboratory Certificates of Analysis and ' Chain of Custody are found in Appendix A of this report. t
