ICES <br /> 4 . 0 SAMPLING ACTIVITIES <br /> ICES collected soil samples on March 1, 2022 . A total of five soil <br /> samples were collected from five test pit locations . The <br /> approximate test pit locations are shown in Figure 2 . <br /> Soil samples were collected from surficial sediments within the <br /> Site at a depth of approximately 6 to 9 inches below the <br /> existing ground surface (bgs) . The soil samples were collected by <br /> scraping the sidewalls of each test pit location at the selected <br /> depth directly into 4-ounce glass jars . <br /> After being sealed and labeled, the soil samples were immediately <br /> placed in a chilled cooler containing crushed ice for <br /> transportation to the laboratory. Proper documentation and field <br /> chain-of-custody procedures were followed. <br /> All equipment used during the sampling activities which might have <br /> come into contact with contaminated materials was thoroughly <br /> decontaminated before and after each use. This was accomplished by <br /> washing with Alconox (a laboratory-grade detergent) and rinsing <br /> with distilled water. <br /> 5 . 0 LABORATORY ANALYSIS <br /> The soil samples collected were sent to McCampbell Analytical, Inc. <br /> of Pacheco, California, a state-certified laboratory and analyzed <br /> as follows . <br /> Organochlorine pesticides using EPA Method 8081B; and <br /> Arsenic, lead, and mercury using EPA Method 6020 . <br /> The samples were analyzed on a normal turnaround basis . <br /> 6. 0 INVESTIGATION RESULTS <br /> The laboratory analytical results are presented below and <br /> summarized in Tables 1 and 2 . Laboratory certificates are included <br /> in Appendix A. <br /> 2 - <br />
