In addition, water level readings taken <br /> <br />during and immediately after completion of each boring are shown at the <br /> <br />lower left corner of the boring logs. A discussion of ground water <br /> <br />conditions at this site is included in the Ground Water Condition section <br /> <br />of this report. <br /> <br />LABORATORY TESTING PROGRAM <br /> <br />In the laboratory, each of the soil samples was carefully examined by an <br /> <br />experienced soil engineer to determine the major and minor soil ,components, <br /> <br />while also noting any inclusions, seams, or lenses foqnd in the samples. <br /> <br /> <br />The samples were then classified on the basis of texture and plasticity in <br /> <br /> <br />accordance with the Unified Soil Classification System (ASTM D-2487 and <br /> <br /> <br />D-2488). The estimated group symbol according to this system of <br /> <br />classification is shown in parentheses following the written description of <br /> <br />the soil on the boring logs. A chart describing the properties of the <br /> <br />various groups of the Unified Soil Classification System is included in the <br /> <br />Appendix. <br /> <br />After classification, the engineer stratified these soils by type as shown <br /> <br />on the boring logs. Please note that the stratification lines shown on the <br /> <br />boring logs represent the approximate boundaries between soil strata. The <br /> <br />actual transition between soil types, in situ, may be gradual in both the <br /> <br />horizontal and vertical directions. <br /> <br />STS Consultants, Ltd. <br />
