George F. Schuler, Inc. <br /> 1705 N. Broa&vay, Stockton, California August 17, 1993 <br /> Phase I Remedial Report Page: 1 <br /> borings were drilled to 65.5 and 71.5 feet in depth, respectively, and were developed into <br /> soil gas vapor extraction wells. All soil samples were screened with a portable PID which <br /> helped determine the final depth of the borings. Laboratory soil samples were taken from <br /> all borings at five foot intervals including the capillary fringe. Samples were selected for <br /> analysis by the registered professional based on odor, discoloration, and PID readings in <br /> order to demonstrate a clean lateral interface (Appendix C & Table 1). <br /> TABLE 1 <br /> Sam le LD.

The soil borings were accomplished using a mobile mounted drilling rig <br /> employing the use of a hollow stem flight auger no less than 3 1/4-inch i.d. and 8 <br /> 7/8 inch o.d. All drilling equipment was thoroughly steam-cleaned before drilling <br /> began, to prevent the introduction of contamination from off site, and between <br /> borings to prevent cross contamination. <br />
