6.2.2 Semivolatile Organic Compounds and Inorganic Contaminants of Concern

Choosing the specific laboratory processes to handle incremental samples is influenced by the specific COPCs and the objectives of the characterization process. In particular, the volatility and thermal stability of the contaminants affects the options for sample conditioning and the objectives for risk assessment influence the choices related to particle size reduction. USEPA SW-846 Method 8330B for explosives is a good detailed example of the complete laboratory process for the analysis of an ISM soil sample (USEPA 2006c). The remainder of this section provides guidance on adapting the principles displayed in USEPA SW-846 Method 8330B to other COPCs.
