II 3} <br /> Problem Assessment Report <br /> y January 29, 1992 <br /> Page -3- <br /> samples were collected at five foot intervals 'for geologic _. <br /> logging and three soil samples from each boring were retained for <br /> laboratory analyses. <br /> 3 . 1 Soil. Borings ' <br /> The soil borings were drilled using 6--inch O.D. hollow-stem <br /> L continuous-flight augers. The auger and sampling equipment were <br /> steamed cleaned before each borehole was -frilled. Soil samples <br /> were collected using a California-modified split-spoon sampler <br /> 3; <br /> fitted with (3) clean brass liners . During the sampling, the <br /> split-spoon was driven ahead of the auger,} The first, or upper- <br /> most. liner was discarded. One sample liner was used for <br /> geological logging and one was prepared for shipment to the <br /> laboratory for analysis . Drilling. :logs were prepared and include - <br /> field observations such as -estimated moisture content and <br /> presence of fuel product- or odor . (Appendix -• B).: <br /> The soil cuttings from the borings were placed on and <br /> covered with plastic sheeting for on site;:storage pending <br /> laboratory results . The soil borings werefilled with a cement <br /> slurry. Disposal of drill cuttings is the responsibility of the <br /> t property owner. _ <br /> i; <br /> is <br /> Soil boring 1 (SBI) was drilled to a-litotal depth of 40 feet. <br /> The soil from the ground surface down to approximately 33 feet <br /> .t <br /> was predominately brown to reddish brown fine- sandy, clayey <br /> CONDOR <br /> Ir <br />
