I. parking areas, ground surface depression near the eastern edge of the site where stormwater runoff concentrates, in areas of former above ground storage tanks (ASTs), tank wash out area, and the residence leach field. A total of eight (8) shallow soil sampling locations were included for this investigation. Please see Plate 3 for sample locations. 4.2.1 Vehicle Parking Area (B-2) Within the former vehicle parking area the soil samples were collected from one location for possible laboratory analysis. The sample location (B-2) was located north of the existing orchard (approximately 50 feet) and west of the eastern site boundary (approximately 100 feet). A total of three soil samples were collected at the surface, 1 foot bgs, and 3 feet bgs in this area for possible laboratory analysis. The 1 foot soil sample from the vehicle parking area was submitted for laboratory analysis. The remaining soil samples were put on hold at the laboratory pending further analysis, if applicable. The sample was analyzed for the list of constituents detailed in Section 5. The results of the laboratory analyses are tabulated in the tables portion of this report and the laboratory data sheets and chain of custody records are included in Appendix E. 4.2.2 Depression Near the Eastern Edge of the Site (B-3 and B-4) A depression of the land surface exists near the eastern edge of the site, and was described to Kleinfelder as an area where surface water pools due to run off at the site. Kleinfelder collected shallow soil samples (B-3 and B-4) from within the depression area for possible laboratory analysis. The soil samples were collected at the surface, 1 foot and 3 feet bgs. The 1-foot soil sample from each location was submitted for laboratory analysis. The remaining soil samples would be put on hold at the laboratory pending further analysis requirements if applicable. The samples were analyzed for the list of analytes detailed in Section 5. The results of the laboratory analyses are tabulated in the tables portion of this report and the laboratory data sheets and chain of custody records are included in Appendix E. 4.2.3 Former AST Areas (B-5 and B-7) I. The anhydrous ammonia above ground storage tank (AST) was formerly located near the northern central portion of the site and former fuel ASTs were located near the center of the site. Kleinfelder advanced a hand auger soil boring in the center of the anhydrous ammonia AST impoundment (B-5) and near the center of the former fuel AST impoundment (B-7) to a total depth of 3 feet bgs. A total of 3 soil samples were collected for possible laboratory analysis at each location. Soil samples were collected from the surface, 1 foot, and 3 foot depths. The 1- foot sample interval was submitted for analysis from the former anhydrous ammonia AST area. Although Kleinfelder's workplan called for analyzing the 1 foot soil sample from each AST impoundment the 3-foot sample collected from the former fuel AST area was submitted for analysis due to a strong odor noted during the advancement of the boring. The remaining soil samples were put on hold at the laboratory pending further analysis requirements if applicable. The sample was analyzed for the list of analytes detailed in Section 5. The results of the laboratory analyses are tabulated in the tables portion of this report and the laboratory data sheets and chain of custody records are included in Appendix E. 27125.E01 / STO4R181 Page 9 of 23 © 2004 Kleinfelder, Inc.
