Appendix A <br />Geotechnical Field Exploration and Testing <br />Report No. P-0016964 <br />The boring logs include descriptions of apparent geology. The geologic depositional origin of each soil layer is interpreted <br />primarily by observation of the soil samples, which can be limited. Observations of the surrounding topography, <br />vegetation, and development can sometimes aid this judgment. <br />A.4 WATER LEVEL MEASUREMENTS <br />The groundwater level measurements are shown at the bottom of the boring logs. The following information appears <br />under "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 <br />boreholes. This is possible because there are several factors that can affect the water level measurements in the <br />borehole. Some of these factors include permeability of each soil layer in profile, presence of perched water, amount of <br />time between water level readings, 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 perAET Procedure 01-LAB-010, which is performed in general accordance with ASTM: D2216 and AASHTO: <br />T265. <br />A.5.2 Sieve Analysis of Soils (thru #200 Sieve) <br />Conducted in general accordance with ASTM:D6913, Method A. <br />A.6 TEST STANDARD LIMITATIONS <br />Field and laboratory testing is done in general conformance with the described procedures. Compliance with any other <br />standards 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 soil recovered from the borings for a <br />period of 30 days. <br />Appendix A - Page 2 of 2 AMERICAN ENGINEERING TESTING, INC. <br />127 <br />
