Ms. Margaret Lagorio <br /> August 25, 1993 <br /> Page 2 . <br /> LABORATORY RESULTS <br /> The analysis for CAM Metals utilized EPA Method 6010/7471. The <br /> results of the analysis are shown in Table 1 below. The results <br /> indicate that the soil is classified not hazardous in accordance <br /> with the California Code of Regulations. A copy of the Laboratory <br /> Data Sheets, which were sent directly to your office by the <br /> Laboratory, are contained in Appendix A. <br /> TABLE 1 <br /> mg/Kg <br /> Metal Sample I D with Amount Reporting <br /> Name C1 C2 C3 Limit <br /> Antimony ND ND ND 2 . 5 <br /> Arsenic 5. 6 5. 1 4 . 2 0. 50 <br /> Barium 200 180 180 1. 0 <br /> Beryllium ND ND ND 0. 25 <br /> Cadmium ND ND ND 0.25 <br /> Chromium 37 33 28 0.25 <br /> Cobalt 18 14 14 1. 0 <br /> Copper 30 27 27 0. 25 <br /> Lead 5. 1 13 ,&i-2-40, �— 2 . 5 <br /> Mercury ND ND ND 0. 025 <br /> Molybdenum ND ND ND 1. 0 <br /> Nickel 31 27 23 1. 0 <br /> Selenium ND ND ND 0. 25 <br /> Silver ND ND ND 0. 25 <br /> Thallium ND ND ND 2 .5 <br /> Vanadium 68 61 56 1. 0 <br /> Zinc 61 60 51 0. 025 <br /> ND = Not Detected <br /> ACUTE TOXICITY TEST RESULTS <br /> The acute toxicity test were performed on the composite soil <br /> samples. The 96 hour static acute bio-assay on "fathead minnows' <br /> was the test selected. The results indicated that the soil should <br /> be classified as non-hazardous because the LC50 value for the 96 <br /> hour acute test was greater than 750 mg/1. The Laboratory Data <br /> Sheets with COC documentation were sent directly to your office by <br /> the Laboratory. A copy of the Laboratory Data Sheets with COC <br /> documentation and the test method is contained in Appendix B. <br />
