�t <br /> Solt Sampling Protocol <br /> (fir <br /> i Sample Collection During Drilling Acti%rities <br /> A Proposal gill be s-ibmitted to the lead Regulatory Authority <br /> with proposed boring/sampling locations. The exact location <br /> and number of borings at each site will be determined in the <br /> � field by the Project Geologist/Engineer <br /> Prior to arriving at the sample site, the drill rig/augers <br /> will be steam cleaned and all sample equipment will be <br /> cleaned Cleararg will be conducted on-site on all sampling <br /> equipment between each sample interval. <br /> Soil samples will be obtained using a California modified <br /> split-spoon sampler containing three, sax inch long, two inch <br /> diameter crass tubes. The sampler will be driven 18 inches <br /> ahead of the nohow stem auger by a lop pound hammer 4ith a <br /> 30 inch drop in accordarce .pith American Society for Testing <br /> and Materials (AST'm) 4ethods D 1586-84 for split barrel <br /> ..ampling of soil and D 1587-83 for thin-walled tube sampling <br /> Of soils. The blows required to drive the sampler each sips <br /> _nch interval wall be recorded on the boring log. The <br /> sampler gill be removed from the boritig and opened to reveal <br /> the brass tubes The bottom tube will be capped wit.,-, <br /> aluminum foil and plastic end caps, taped and labeled with <br /> the follow,ng information date, time, ,project 1D, sample <br /> :D, name of sampler and type of analysis. This sample wall <br /> be :.mmediately placed into a cooler containing dry ace or <br /> frozen "olue ice" A "high-low" temperature recording <br /> thermometer will accompany sample shipments to ensure proper <br /> temperature maintenance. The samples will be delivered to a <br /> state cert+faed laboratory under chain-of-custody protocol <br /> within 48 hours of sampling, 4hen ever possible. <br /> Soil in the uppermost brass tube gill be described according <br /> to ASTM standard, practi-e for description and identification <br /> Of soils (ASTM D-2488-84) Stratigraphic, genetic and other <br /> data/interpretations gall also be recorded. Soil properties <br /> also be noted in the ;riddle brass tube and from the sampler <br /> shoe. Alternatively the second sample tube may be used with <br /> the uppermost tube for preparation of duplicates. These <br /> field observations will be noted on a log prepared tar each <br /> boring/ Jell <br /> During sampling, latex gloves will be worn to preve•,t cross- <br /> contamination with other samples. The disposable gloves will <br /> be discarded after collecting samples from each 18-inch <br /> sample drive. <br />
