Smith Environmental Technologies Corporation <br />Quality Assurance/Quality Control Plan <br />Revised February 1995 <br />This sample will be immediately placed into a cooler containing dry ice or frozen chemical ice. <br />A "high -low" temperature recording thermometer will accompany sample shipments to ensure <br />proper temperature maintenance. The samples will be delivered to a state certified laboratory <br />following under chain -of -custody protocol within 48 hours of sampling, whenever possible. <br />Soil in the uppermost brass tube will be described according to ASTM standard practice for <br />description and identification of soils (ASTM D-2488-84). Stratigraphic, genetic and other <br />data/interpretations will also be recorded. Soil properties may also be determined from the <br />middle brass tube and from the sampler shoe. Alternatively the second sample tube may be <br />used with the uppermost tube for preparation of duplicates. These field observations will be <br />noted on a log prepared for each boring/well. <br />During sampling, latex gloves will be worn to prevent cross- contamination with other samples. <br />The disposable gloves will be discarded after collecting samples from each 18 -inch sample <br />drive. <br />Soil samples will be collected at 5 -foot intervals, at significant changes in lithology and intervals <br />of obvious contamination in order to develop a complete profile of soil contamination. <br />11.2 Sample Collection During Tank Removal <br />Sod samples will be collected as soon as possible after removal of the tank Where feasible, all <br />preparations for sod sampling will be made prior to tank removal. Soil samples collected from <br />a backhoe bucket or directly from the excavation floor will be collected in a thin-walled <br />stainless steel or brass cylinder at least 3 -inches long by 1 -inch in diameter.
