Field Documentation <br />Surveying <br />October 2012 <br />Rock sample descriptions will include information such as: <br />• Rock type; <br />• Relative hardness; <br />• Density; <br />• Texture; <br />• Color; <br />• Weathering; <br />• Bedding; <br />• Fractures, joints, bedding planes; and <br />• Mineralogy (e.g., observable pyrite, if present). <br />1 \10 \81640\ 0400\ characterizationpin_ fnl- 23octl2 \charactenzationpin_fnl- 23oct12 docx <br />Attorney Work Product, <br />Confidential and Privileged <br />9 <br />103- 81640A <br />and allow access for water level measurement. A concrete pad, approximately 3 -foot square, sloping <br />away from the well, will be constructed around the protective casing. The vicinity of the well sites will be <br />reclaimed and re- seeded to pre - drilling conditions following well construction. Holcim will provide the <br />seed mix specifications for re- seeding. <br />A field hydrogeologist/engineer will be on site during drilling to prepare a lithologic log of each borehole as <br />drilling progresses. Soil descriptions will include some or all of the following: <br />• Descriptive USCS classification in accordance with ASTM D2488; <br />• Consistency of cohesive materials or apparent density of non - cohesive materials; <br />• Moisture content assessment, e.g., moist, wet, saturated, etc.; <br />• Color; <br />• Depositional type (alluvium, till, loess, etc.), if practical; and <br />• Other descriptive features (bedding characteristics, mineralization /oxidation, organic <br />materials, macrostructure of fine - grained soils; e.g., root holes, fractures, etc.). <br />As described previously, packer testing data will include all flow and pressure readings recorded on a field <br />form or in a field book. Also, well construction details will be documented on a well construction log. <br />Surveying will be performed following well construction so that groundwater elevations can be established <br />for monitoring flow directions and determining hydraulic gradients. Surveying activities will be performed <br />by a licensed surveyor and will be tied into the same coordinate system used for other surveying at the <br />Site. At each well location, the elevations of the ground surface and top of PVC well will be surveyed to <br />an accuracy of 1/100 foot. <br />Golder <br />Associates <br />
