Soil Sample Collection <br /> Soil samples were collected in a two-inch diameter California modified split-spoon <br /> sampler at intervals of five feet unless sample too] refusal was encountered. The sampler <br /> was driven in advance of the augers to collect relatively undisturbed samples for logging <br /> and possible laboratory analysis. Blow counts were recorded for each six inch interval. <br /> Refusal was reached if a total of fifty blow counts were required to drive the sampling tool <br /> F! six inches. Sampling for that interval was then suspended and drilling was resumed. f <br /> Soil samples from the split spoon were collected in clean brass or stainless steel <br /> sampling tubes. Once retrieved from the split spoon, liner ends were covered with plastic <br /> end caps to inhibit the escape of water vapor. <br /> All soil samples collected for laboratory analysis were labeled with the location, date <br /> and time, and immediately placed into a cooler chilled to 4° Celsius and containing "blue <br /> F', ice" coolant. All sampling information was recorded on the boring log forms. <br /> The site geologist described all soil samples in the field. Field observations noting <br /> ' sediment type, color, grain size, sorting, hardness, texture, clay content, moisture content, <br /> visible evidence of contamination, odor, and any other information important to the <br /> investigation were recorded in the field on appropriate log forms by the site geologist. <br /> 1..: <br /> �{ I <br /> ! t F <br /> F1 <br /> 4f <br /> I <br /> F <br /> F., <br /> F' <br /> a <br /> F, <br /> 0 Western Design!David Avila 2000 29 <br /> Fi <br /> I <br /> i <br />
