i <br /> l <br /> _• TABLE 1 <br /> CAM METALS IN SOIL <br /> DETECTIONS GREATER THAN STLCs <br /> mg/L (ppm) <br /> SAMPLF— B3-0.5 B4-0.5 B5-05 B6-0.5 STLC <br /> COPPER 638 247 568 571 25 <br /> LEAD — — 11.1 — <br /> 5.0 <br /> — Result detected below STLC <br /> Elevated levels of copper were detected in the near surface soils along the conveyor system <br /> easement and in the area of the former copper concentrate stockpile. Although testing of deeper soil <br /> along the conveyors was limited, copper was not detected above the STLC in any of the samples collected <br /> from the capillary fringe. <br /> i <br /> Elevated levels of lead were detected in the near surface soils in the area of the adjoining <br /> conveyor near the dockside boom tower. Lead was not detected above the STLC in near surface soils <br /> at any other location or in any samples collected from the capillary fringe. <br /> 4.1.2 Chlorinated Pesticides and PCBs <br /> Chlorinated Pesticides and PCBs were not detected in any of the samples analyzed. <br /> Comprehensive laboratory analytical data reports are included in Appendix B. <br /> 4.1.3 Organophosphate Pesticides <br /> Organophosphate Pesticides were not detected in any of the samples analyzed. Comprehensive <br /> laboratory analytical data reports are included in Appendix B. <br /> ` 4.1.4 Total Recoverable Petroleum Hydrocarbons <br /> Total Recoverable Petroleum Hydrocarbons (TRPH) were detected in 11 of 14 soil samples <br /> analyzed, and are presented in Table 2.
