Stockton Plating Inc. <br /> soil s Groundwater Investigation <br /> April 19, 1994 <br /> Page <br /> soil cuttings from the borings were placed in steel storage <br /> containers supplied by SPI. Disposal of drill cuttings and <br /> hazardous materials is the responsibility of the property owner. <br /> The soil samples were logged according to the Unified Soil <br /> Classification System and the geologic logs are included an <br /> Appendix A. The soils encountered during the drilling of the 3 <br /> monitor wells was similar to that encountered during previous <br /> drilling at SPT . The soils generally consisted of salty, clay <br />' interbedded with lenses of sand and salt. Geologic cross <br />' sections are illustrated in Figures 3 , 4, 5 and 6 . Olive-brown <br /> to grey-green soil was present in each boring at a depth of <br /> approximately 25 feet below ground surface to the bottom of each <br /> borehole. Soils with septic odors were present in MW1 and MW2 at <br /> a depth of approximately 40 feet below ground surface. In MW3, a <br /> gasoline odor was encountered at a depth of 20 feet and septic- <br /> petroleum odors were present at a depth of 25 feet. A soil <br /> sample collected at a depth of 60 feet from MW1 for geologic <br /> logging was grey-green and had a septic odor. <br />' During the drilling, each soil sample was screened in the <br /> field with an Organic Vapor Analyzer (OVA-PID) . The PID <br /> measurements for soil samples collected from MW1 and MW2 revealed <br /> no organic vapors in the soil from the ground surface to a depth <br /> of approximately 35 feet. At the 40 and 45 foot depths in MW1 <br /> �� CONDOR <br />
