The site sampling plan will specify which of the following procedures will be used. <br /> Soil samples for chemical analysis should be collected in the following order: (1) volatile <br /> organics, (2) semivolatile organics and other organics (e.g., pesticides, polychlorinated <br /> biphenyls (PCB)), and (3) metals. Once the chemical samples have been containerized, <br /> samples for physical analyses can be containerized. Typical physical analyses conducted <br /> include (1) grain size distribution, (2) moisture content, (3) saturated permeability, <br /> (4) unsaturated permeability, and (5) Atterberg limits. Additionally, visual descriptions of <br />
