Logging of Borings <br /> Soil samples are logged using the Unified Soil Classification System. Samples not selected <br /> for chemical analysis and the soil sampler shoe are extruded in the field for examination. <br /> The texture, color, moisture, plasticity, and consistency of soil; the blow counts; the <br /> subjective evidence of hydrocarbons, such as soil staining and obvious product odor, and <br /> photoionization detector (or similar instrument) readings are noted in the field on the Logs <br /> of Borings. <br /> Sampling of Drill Cuttings <br /> Soil samples are collected from the stockpiled drill cuttings by driving a hand-operated <br /> percussion sampler fitted with a clean brass sleeve into the stockpiled soil. The sleeve is <br /> removed from the sampler and promptly sealed with Teflon tape and plastic caps. The <br /> sample is then labeled and placed in iced storage. Chain-of-Custody Records are initiated <br /> by the geologist and accompany the samples to the analytical laboratory. Pending the <br /> analytical results of the soil samples, Manley and Sons of Sacramento, California, will <br /> arrange for disposal of the drill cuttings at an appropriate disposal facility. <br /> SA(_\ti:\PIZ\2605\26051010.1 AB-96\1 1b:l <br /> i <br />
