Anderson & Associates, Inc., to a depth of 17 feet <br /> to characterize the soil profile of the proposed septic field. No ground water was encountered in <br /> the boring. Generally, sandy clay mixtures and silty sand with clay mixtures were encountered <br /> within the boring. The soil layer appeared to be heterogeneous in layering. Table 4 presents the <br /> log of the 17-foot soil boring. <br /> Table 4. <br /> 17-foot Soil Prof-tie Log. <br /> Depth(feet) Soil(Unified Soil Classification System) <br /> 0-3 Dark brown clayey sand/sandy clay(SC/CL). <br /> 3 -6 Clayey fine sand/fine sandy clay(SC/CL). <br /> 6- 12.5 Fine silty sand(SM)with thin clayey layers. <br /> 12.5- 17 Sandy clay(CL),very stiff. <br /> i Q,t�4 <br />
