�1 <br /> Water'Work <br /> Soil Samolan ProtoI-01 <br /> A propos:ii will be submitted to the Public Health Division of the <br /> County N:alt:h (Department with proposed boring/sampling locations. <br /> The exact location and number of borings at each site will be <br /> determined in the field by the Project Geologist. <br /> �s <br /> Prior to arriving at the sample site, -the dril- rig/augers will <br /> be steam cleaned and sample equipment will be washed with <br /> laboratory grade detergent and rinsed twice with tap water and <br /> once with deionized water. This procedure will be conducted on <br /> site on all sampling equipment between each sample interval. <br /> Soil samples will be obtained using a California modified split- <br /> spoon sampler containing three, six inch long, =wo 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 D 1586-84 for split barrel sampling of soil and D 1e h <br /> for thin-walled tube sampling of soils. The blows to drive the <br /> sampler each six inch interval will be recorded on the boring <br /> oved from the <br /> log. The sampler will be remboring and opened to <br /> reveal the brass tubes, The' bottom tube wi�l be capped with <br /> aluminum foil and plastic end caps, taped and labeled with the <br /> following information: date, time, project ID, sample ID, name of <br /> sampler and type of analysis. This sample will be immediately <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 ;4ith 48 hours of sampling, when <br /> possible. <br /> _ Soil in the uppermost brass tube will be described for texture, <br /> color, consistency, moisture content, presence of contamination <br /> and any other distinguishing characteristics. 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 3 log prepared <br /> for each boring/well . <br /> During sampling, latex gloves .gill 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 />
