This procedure will be conducted on <br /> site on all sampling equipment between each sample intarval. <br /> Sail. samples will be obtained using a California modified split- <br /> -spoon sampler containing three, six inch long, two inch diameter <br /> brass tubes. The sampler will be driven 18 inches ahead of the <br /> hollow stem auger by a 140 pound hammer with a 30 inch drop in <br /> - accordance with American Society for Testing and Materials (ASTM) <br /> Methods r, 1586-84 for split barrel sampling of soil and D 1587-83 <br /> for thin-we'!led tube sampling of soils. The blows to drive the <br /> sampler each six inch interval will, be recorded on the boring <br /> log. The sampler will be .removed from the boring and opened to <br /> reveal the brass tubes. The bottom tube will be capped with <br /> aluminum *:oil and plastic end caps, taped and labeled with the <br /> following information: date, time, project ID, sample IA, name of <br /> sampler and type of analysis. This sample will be immediately <br /> k: <br /> placed into a cooler containing dry ice or "blue ice". The <br /> samples will be delivered to a state certified laboratory under <br /> chain-of-custody protocol with 48 hours of sampling, when <br /> possible. <br /> Soil in the un ermost brass tube u3? <br /> 'F P l be described for texture, <br /> color, consistency, moisture conifnt, presence of contamination <br /> and any other distinguishing churac•teristics. Soil properties <br /> will also be noted in the middle brass tube and from the sampler <br /> shoe. These field observations will be noted on a log prepared <br /> for each boring/well. <br /> During sampling, latex gloves will be worn to prevent cross- <br /> contamination with other samples. The disposable gloves will be <br /> discarded after collecting samples from each 18-inch sample <br /> drive. <br /> h' <br /> END, 31111111al IN 1.111110111 111 <br />
