MOHR-FRY Ranches <br /> 950 Industrial Drive, Stockton, California Tune 2, 1993 <br /> Phase II Remedial Report Page: 2 <br /> 3.0 Scope of Work <br /> WHF Environmental conducted six soil borings in the vicuuty of the former <br /> underground tanks (Figure 2). Two of the borings located adjacent to each of the <br />' former underground storage tanks were developed into monitoring wells. A third <br /> boring, developed into a monitoring well was located towards the south of the two <br /> former tank excavations. The additional borings were located around the former tank <br /> excavations to help in the lateral definition of the soil contamination. <br /> Laboratory soil samples were taken from all borings at five foot intervals including the <br />' capillary fringe. Samples from each boring were selected for analysts by the registered <br /> professional based on odor, discoloration, PID readings, and previous findings to order <br /> to demonstrate a clean lateral interface The other samples were held by WHF in a <br />' freezer pending the results of the first samples. The only additional samples submitted <br /> for analysis were from boring MW-2 at 35 and 45 feet. These samples were included <br /> in order to better define the limits of contamination between the 25 and 50 foot <br /> samples. <br /> Laboratory results for soil sample are presented in Table 1 and Appendix.
