3. SOIL CLASSIFICATION <br /> 3.1 Overview <br /> This SOP was prepared to direct field personnel in the method for describing soil samples. <br /> The SOP conforms to the American Society for Testing and Materials(ASTM) Standard <br /> D 2488, Standard Practice for Description and Identification of Soils, ASTM Standard <br /> D-2487-11, Standard Practice for Classification of Soils for Engineering Purposes, and <br /> other pertinent technical publications. The objective of soil sample description is to <br /> provide consistent geological information useful for the purpose of hydrogeological or <br /> geotechnical evaluation of a site. The Unified Soil Classification System (USCS) is the <br /> suggested classification method. <br /> 3.2 Equipment <br /> • PPE and air monitoring equipment as required by HASP; <br /> • Grain size chart; <br /> • Measuring tape or folding ruler at least five feet in length; <br /> • Polyethylene sheeting; <br /> • Munsell color chart; <br /> • Spoon or small spatula; <br /> • Water. <br /> 0 '/2" reinforcing rod (rebar); and <br /> • 5-pound hammer. <br /> 3.3 Documentation <br /> • DFRs; <br /> • Soil boring logs; <br /> • Camera; and <br /> • Note cards or white board for photo documentation. <br /> 6 <br />
