5.0 SUBSURFACE INVESTIGATION <br /> Soil Borin s <br /> g <br /> To assist in the Site characterization, nine subsurface borings were drilled to a maximum depth <br /> of 9 feet below ground surface. The borings were located in areas of the Site where active <br /> machinery and chemical usage and storage is occurring. The location of soil borings are shown <br /> on Figure 5. Soil borings and sampling were performed and collected using a hand auger and <br /> sampler containing a 6-inch long, 2-inch diameter brass sampling tube. The depth of borings, <br /> depth of soil samples and chemical analyzes performed -on samples are presented on Table 1. <br /> Analytical Results <br /> ' For all soil samples collected EPA method 8015 for motor oil was performed, in addition EPA <br /> method 8240 was performed for the soil sample (13-7-5) collected in the vicinity of the waste <br /> anti-freeze storage drum; detection limits ranged from 100 to 500 ug/Kg. Soil samples collected <br /> from the waste oil storage room were analyzed by EPA method 8015 (Modified) for transmission <br /> oil; detection limits ranged from 1.0 to 10.0 mg/Kg. Copies of the chain of custody and <br /> analytical report documents are included in Appendix H. The chemical analyses for all soil <br /> ' samples collected from the site indicated that none of the parameters requested were <br /> present within the soil above analytical detection limits. <br /> ' Privileged and Confidential Prepared at the Request of Counsel <br /> ' 18 <br />
