undisturbed samples of the bedrock were obtained during drilling operations. Twelve <br /> shallow borings were also investigated for the presence of petroleum releases in <br /> conjunction with an engineer from AWES, LLC. <br /> Samples from the borings were returned to our laboratory, visually classified and selected <br /> for testing. Graphic logs of the soils found in the borings and some of the laboratory <br /> testing results are presented on Figures 2 through 5, Logs of Borings. The Legend and <br /> Notes to interpret these logs are included as Figure 6. <br /> Included on the gradation and summary figures are descriptions of the soils encountered. <br /> Laboratory testing included moisture content and dry density, ASTM D 2216, washed <br /> gradation analysis, ASTM C 117 and C 136, liquid limit, plastic limit and plasticity <br /> index, ASTM D 4318, and unconfined compressive strength, ASTM D 2166. These test <br /> results are presented on Tables 1 through 3, Summary of Test Results, and Logs of <br /> Borings, Figures 2 through 5. <br /> SUBSURFACE AND GROUNDWATER CONDITIONS <br /> The subsurface conditions encountered in the borings generally consisted of one-half foot <br /> of topsoil overlying overburden which varied from silty sandy clay to silty sand. Beneath <br /> the overburden we encountered SAND, occasional gravel; SAND, with gravel; SAND, <br /> gravelly; Silty clayey SAND; CLAY; Claystone-Siltstone-Sandstone Bedrock; Claystone <br /> Bedrock and Sandstone-Siltstone Bedrock. Please refer to the Log of Borings, Figures 2 <br /> through 5, and the Legend and Notes prepared to interpret these logs, Figure 6, as each <br /> material is described below. <br /> TOPSOIL <br /> One-half foot of topsoil was encountered in all of the borings except borings 10 and 11. <br /> The topsoil is dark brown to black and organic. <br /> Two Rivers Property,WesTest Project No. 440515,February 12,2015 4 <br />
