-rt <br /> Soil Physical Properties Analysis <br /> A&L Western Laboratories also performed sail textural analyses on eight samples from <br /> Y � les p <br /> the soil boring. The percentage of particle sizes falling within the sand, silt and clay <br /> fractions were determined for each of the samples. FINDINGS <br /> Soil Profile <br /> Although there are two wells located on the property, there are no driller's or geologist's <br /> logs for these borings. <br /> The soil profile intersected in the soil boring consisted of and upper unit of fine to <br /> medium-grained sand, which extended down to approximately 14 feet below ground <br /> surface. A ten foot thick silt bed was encountered from 14 to 24 feet. From there to the <br /> bottom of the boring at a depth of 41 feet,the lithology was medium to coarse-grained <br /> loose sand. Inspection of soil emerging from the borehole on the auger flights indicated <br /> that there was a layer of clay at a depth of about 32-34 feet. However, this layer would <br /> have been between the intervals sampled by the split spoon and no sample was collected of <br /> this unit. <br /> tf <br /> A tabulation of soil textures and hydraulic conductivities determined for the samples <br /> collected from the boring at the Joe Da Silva site are reported in Table L, below. <br /> Table 1.
