Characterizing Burn Dumps in California, DTSC recommends that soil/ash samples be <br />collected and analyzed to meet the site specific DQOs, and the analytical results <br />compared to the specified hazardous waste classification criteria for the selected <br />extraction procedures as listed below and presented in Table 1, Criteria for Evaluating <br />Analytical Results for Metals in Soil: <br />1. All samples should be analyzed using the Total Metals Analysis procedure for <br />metals (Sb, As, Ba, Be, Cd , Cr (III), Cr (VI) Co, Cu, Pb, Hg, Mo, Ni, Se, Ag, Tl, <br />V, Zn) (former CAM-17 metals); and the analytical results compared to TTLC <br />criteria. Concurrently, all samples should be analyzed for soil acidity. <br />2. The three samples which exhibit the highest total lead concentrations, should <br />undergo additional analysis using the WET procedure for Cd, Cr (III), Cr (VI), <br />Ni, Pb, and Zn (former CAM-5 metals); and the analytical results compared to <br />STLC criteria. <br />3. Based on the Total Metals Analysis, samples that demonstrate a metal that <br />exceeds ten times the STLC criteria should also be analyzed for that metal using <br />the WET method; and the analytical results compared to STLC criteria. <br />4. Additionally, the three samples that exhibit the highest lead concentration should <br />be analyzed using the TCLP procedure for RCRA metals [Ag, As, Ba, Cd, Cr <br />(total), Hg, Pb, and Se]; and the analytical results compared to Characteristics of <br />Toxicity criteria. <br />5. In addition to the analysis described above, samples that demonstrate the highest <br />concentrations for lead should be analyzed using the DI WET method for lead; <br />and the analytical results compared to DI-WET criteria or evaluated for the <br />potential to migrate to groundwater. <br />Appropriate analytical methods must meet site-specific DQOs and may include the <br />following methods: <br />Metals, by EPA Methods 6010 or 6020 or 7000 series <br />Soil (pH), EPA Method 9045 <br />Source: Department of Toxic Substances Control, June 2003, Protocol For Burn Dump Site <br />Investigation and Characterization DRAFT
