APPENDIX A <br />E-6140 <br />� � �;t I�i <br />Our field Axploration was pertormed on March 2fi, 1993. Subsurface conditiona at the site <br />were explored by excavatinp fivo test pits to a maximum depth of fourteen feet below the <br />existing ground surface. The test pits were excavated by Sooa Creek Excavation, using e <br />rubber tired backhoe. <br />The a�proximate test pit locations were determined by taping from property corners and <br />existing site features. The locations of the test pits should be cnnsidered accurate only to the <br />depree implled by the method uaed. Tliese approximate tocations are shown on the Test Pit <br />Location Plan, Plate 2. The iield explo��ation was continuously rr►onitored by a geoloplat from <br />our firm, who claasifted the soils encountered and matntatned a Ing of each teat pit, obtained <br />representative samples, measured proundwater levela, and observed pertinent aite featur,9s. <br />Repreaentative soil samples were placed in closed conta(nera and returned to our laboratory <br />for further examination and teating. <br />All samplea were visually classified in accordance with the Unified Sotl Class,ification System <br />which ts presented on Plate A1, Leflend. Logs of the test pits are presented in the Appendix <br />on Platea A2 throuph A6. The ftnal lo8s reprasent our Interpretationa of the field lo�s and the <br />reaults of the laboratory tests on field samples. The atratification lines on the logs represent <br />the approximate boundaries between soil ty�ss. In actuality, the transittons may be, rrw�e <br />gradual. <br />x <br />Earth Coneultanta, Inc. <br />
