Drummed water will be <br /> labeled with the source; of the water to help ensures <br /> appropriate disposal used on contamination levels. <br /> 11.0 Soil Sampling Protocol <br /> 11.1 SaLopla Collection During Drilling Activities <br /> A proposal will be submitted to the lead Regulatory <br /> Authority with proposed boring/sampling <br /> locations. The <br /> exact location and number of boring& at each site will b* <br /> determined in the field by the Project Geologist/Engineer. <br /> Prior to arriving at the sample site, the drill rig/augers <br /> will b!o Steam cleaned and all sample equipment will be <br /> cleaned. Cleaning will be conducted on-site an all sampling <br /> --equipment-between-each sample--interval.- <br /> Soil samples will be obtained using a California modified <br /> split-spoon sampler ccntaining three, six Inch long, two <br /> inch diameter brass '.ubes. The sampler will be driven 18 <br /> inches ahead Of the hollow stem auger by a 140 pound her <br /> with a 30 inch drop in awcordance with American Society for <br />
