<br /> Weaver Consultants Group <br /> <br />4 <br /> <br />was stiff to very stiff based on hand penetrometer readings ranging from 1.4 to 3 tons per <br />square feet (tsf), and moisture contents ranging from 10 to 13 percent. <br />3.2 Groundwater Conditions <br />Groundwater level observations noted during and after completion of the drilling operations are <br />recorded on the boring logs. Based on these observations, groundwater was encountered at <br />depths about 5 to 5½ feet bgs. Given the presence of near surface granular soil underlain by less <br />permeable silt, it is our opinion that the groundwater is perched on the silt stratum. Sand deposits <br />are relatively pervious, and water can drain into the borehole somewhat quickly and come to an <br />equilibrium position. However, fluctuations in the water table should be anticipated througho ut <br />the year with variations in precipitation and other environmental or physical factors. Seasonal <br />fluctuations in the groundwater level should be expected due to variations in precipitation, <br />evaporation and surface water runoff.
