Appendix A (continuation) <br /> Page 2, W-5557 <br /> interval, the blow count is recorded as 50 blows for the number of inches of <br /> penetration. The resistance, or "Nu value, provides a measure of the relative <br /> density of granular soils or the relative consistency of cohesive soils. <br /> The soil samples obtained from the split-barrel sampler were classified in the <br /> field and representative portions placed in watertight containers. The samples <br /> were then transported to our laboratory for further visual classification and <br /> laboratory testing. Samples are generally saved for a period of 30 days unless <br /> special arrangements are made. <br /> The boring logs presented in this appendix are based on the drilling action, <br /> inspection of the samples secured, laboratory results and field logs. The various <br /> 1 types of soils are indicated as well as the depths where the soils or characteristics <br /> of the soils changed. It should be noted that these changes may have been gradual , <br /> and if the changes occured between sample intervals, they were interpreted. <br /> The ground water conditions observed during the exploration program are indicated <br /> on the boring logs. These subsurface water conditions were evaluated by observing <br /> l the moisture condition of the samples, or the free water on the sampling rods. The <br /> ground water level is indicated on the boring logs where appropriate by the water <br /> symbol. <br /> J <br /> J <br /> l <br /> J <br />
