Predominant material types shown on the log may contain different materials and the change from <br />one predominant material type to another could be different than indicated. Descriptions on this log apply only at the specific <br />location at the time of drilling and may not be representative of subsurface conditions at other locations or times. <br />Project No. 40007-130-01 Date MAY 97 <br />Log of Boring <br />Figure <br />A-7 (sheet 1 of 1) <br />
