FIELD METHODS <br /> On August 10, 1993, nine discreet soil samples were collected in <br /> clean brass tubes, sealed with plastic caps and taped, labeled, <br /> held in a cooler at 4 degrees C and transported under Chain-of- <br /> Custody (COC) documentation to a state certified laboratory for <br /> compositing, with a subsequent analysis and fish bio assay. <br /> Soil samples S1, S4 and S7 made up one composite sample (Cl) , S2 , <br /> S5 and S8 made up the second composite sample (C2) while S3 , S6 and <br /> S9 made up the third composite sample (C3) . <br /> On February 22, 1994, eight discreet samples from the stockpile <br /> were acquired, the samples identified as S10, S11, S12 , and S13 <br /> were composited on site into composite sample (C3) while the <br /> samples identified as S14, S15, S16, and S17 were composited on <br /> site into composite sample (C4) . C3 and C4 were put into clean <br /> brass tubes, sealed with plastic caps and taped, labeled, held in <br /> a cooler at 4 degrees C and transported under Chain-of-Custody <br /> (COC) documentation to a state certified laboratory for analysis. <br /> LABORATORY RESULTS <br /> The analysis for CAM Metals utilized EPA Method 6010/7471. The <br /> results of the analysis in parts per million (ppm) are shown in <br /> Table 1 below. The metal concentrations are those expected for <br /> background levels. The results indicate that the soil is <br /> classified as not hazardous in accordance with the California Code <br /> of Regulations.
