B-2 <br /> C. Sample preservation <br /> CAll samples should' be cooled to- below 4 degrees C. <br /> d. Sample Collection <br /> Soils will be cored and sampled using a hollow-stem flight. <br /> auger and split-spoon sampler. <br /> i . Representative soil samples will be collected by <br /> utilizing the hollow-stem auger and soil sampler. The <br /> process involves clearing the sample location of <br /> surface debris such as weeds or discarded materials and <br /> . coring the soil zones .with the auger to the prescribed <br /> sampling depth. The auger would be used to deepen the <br /> sample hole to each sampling depth. After the split- <br /> spoon removes the sample the procedure would be <br /> repeated until the maximum sample depth is reached. <br /> This depth is generally above the capillary fringe of <br /> first ground water. <br /> ii . The soils at the Aurora Way property have been mapped-' <br /> as Stockton clay, therefore auger borehole integrity <br /> will probably not be a concern. <br /> e. Equipment cleaning <br /> All soil sampling equipment will be cleaned using a non- <br /> phosphate detergent solution and a de-ionized water rinse <br /> for samples to be analyzed 'for metals {Pb} and total <br /> petroleum hydrocarbons . <br /> f. Safety plan <br /> All soil sample collection and handling will be conducted, in <br /> conformance with the site health and safety plan as <br /> presented in Appendix C. <br /> g. Sample transport <br /> All labeled samples will be cooled and transported to the <br /> laboratory as soon as possible. Chain of custody forms and <br /> C <br />
