IK Kennedy Jenks <br /> • USCS (ASTM D 2488-06) table and classification chart. <br /> • Soil color chart (i.e., Munsell). If used, the edition of the Munsell chart should be specified on <br /> each borehole log as the color descriptions and hue, color values and chromas have <br /> changed between editions. Also, whenever possible, the newest version of Munsell's color <br /> charts should be used due to fading of color chips over time. <br /> • American Geological Institute (AGI) Data Sheets. <br /> • Engineer's scale. <br /> • Previous project reports and boring logs (if available). <br /> • Pocket knife or putty knife. <br /> • Hand lens. <br /> • Supply of clean water. <br /> • Aluminum foil, Teflon®sheets, and paper towels. <br /> • Sample containers (brass, stainless steel or aluminum liners, plastic, or glass jars). <br /> • Clean rags or paper towels. <br /> • Sample shipping and packaging supplies. <br /> • Personnel and equipment decontamination supplies. <br /> • Personal protective equipment as described in the HASP. <br /> C.3 Typical Procedures <br /> Soil classification and borehole logging should be conducted by a qualified geologist, engineer, or <br /> other personnel trained and experienced in the classification of soils. <br /> Soils are typically logged in conjunction with advancing boreholes and sampling subsurface soils. <br /> Although the guideline focuses on classifying soil samples obtained from boreholes, this particular <br /> procedure also applies to soils and sediments collected using other techniques (e.g., post hole <br /> digger, scoop, Ekman, Ponar, or Van Veen grab samplers, and backhoe). <br /> The USCS as described in ASTM D2488-06 categorizes soils into 15 basic group names, each with <br /> distinct geologic and engineering properties. The following steps are required to classify a soil <br /> sample: <br /> 1. Observe basic properties and characteristics of the soil. These include grain-size grading and <br /> distribution and influence of moisture on fine-grained soil. <br /> 2. Assign the soil a USCS classification and denote it by the standard group name and symbol. <br /> 3. Provide a written description to differentiate between soils in the same group, if necessary. <br /> Monitoring Well Installation Work Plan, 8-2 <br /> The Wine Group, Franzia Winery, Ripon, CA <br /> P.\1S-Proj\2003-post archive\030120.XY_GW Mon Well Support\09-Reports\piecesWPP_C SOG Borehole Log.doc <br />
