•Merila and Associates <br />STS project 93492 <br />December 19, 1984 <br />-3- <br />ANALYSIS AND RESULTS <br />Subsurface Exploration <br />The seven (7) soil borings drilled for this exploration were performed <br />using a track -mounted all terrain vehicle auger type drill rig which <br />used continuous flight augers to advance the borings to full depth. <br />The borings were numbered B-17 through B-23, with the initial sixteen <br />borings drilled during previous studies of this site. <br />While drilling, representative soil samples were obtained using the <br />split -barrel and Shelby tube sampling procedures in general conformance <br />with ASTM specification D 1586 and D 1587, respectively. Continuous <br />field logs of the drilling procedures and soil samples obtained were <br />maintained by the drill crew. The drilling and sampling procedures are <br />described in more detail in the Appendix of this report. <br />The soil samples recovered during the drilling operations were returned <br />to our laboratory for further visual examination, classification and <br />laboratory testing. <br />r, <br />
