Appendix A <br /> Geotechnical Field Exploration and Testing <br /> AET Project No. 22-00012 <br /> The ground water level measurements are shown at the bottom of the boring logs. The following information appears under <br /> "Water Level Measurements"on the logs: <br /> • Date and Time of measurement <br /> • Sampled Depth: lowest depth of soil sampling at the time of measurement <br /> • Casing Depth:depth to bottom of casing or hollow-stem auger at time of measurement <br /> • Cave-in Depth:depth at which measuring tape stops in the borehole <br /> • Water Level:depth in the borehole where free water is encountered <br /> • Drilling Fluid Level:same as Water Level,except that the liquid in the borehole is drilling fluid <br /> The true location of the water table at the boring locations may be different than the water levels measured in the boreholes.This is <br /> possible because there are several factors that can affect the water level measurements in the borehole. Some of these factors <br /> include: permeability of each soil layer in profile, presence of perched water, amount of time between water level readings, <br /> presence of drilling fluid,weather conditions,and use of borehole casing. <br /> A.5 LABORATORY TEST METHODS <br /> A.5.1 Water Content Tests <br /> Conducted per AET Procedure 01-LAB-010,which is performed in general accordance with ASTM:D2216 and AASHTO:T265. <br /> A.6 TEST STANDARD LIMITATIONS <br /> Field and laboratory testing is done in general conformance with the described procedures. Compliance with any other standards <br /> referenced within the specified standard is neither inferred nor implied. <br /> A.7 SAMPLE STORAGE <br /> Unless notified to do otherwise,we routinely retain representative samples of the soils recovered from the borings for a period of <br /> 30 days. <br /> Appendix A-Page 2 of 2 AMERICAN ENGINEERING TESTING,INC. <br />
