2. Section 2.2.3.1, Page 2-3: This section states that the results of the <br /> stockpiled soil sampling event in 1998 showed that pesticides and <br /> selenium were present in the soil at DSERTS 72. However, the Report <br /> does not indicate that other metals' and TPH were also present in the <br /> soil, but presumably below their respective cleanup goal. For <br /> consistency, please revise this section to indicate that pesticides and <br /> selenium were present above their respective cleanup goals. <br /> 3. Section 2.2.3.2 and Figure 2-2: The text states that the maximum <br /> concentration of total DDX detected during the October 1999 and March <br /> 2000 sampling event was 0.299 mg/kg, and the maximum detected dieldrin <br /> concentration was 0.06 mg/kg. However, according to Appendix C and <br /> Figure 2-2, the maximum detected DDX concentration was 0.541 mg/kg and <br /> the maximum detected dieldrin concentration was 0.073 mg/kg. Please, <br /> revise the text to reflect the correct maximum concentrations for DDX <br /> and dieldrin. This comment may affect the exposure point calculations <br /> performed as part of the human health risk assessment. Please, clarify <br /> how the concentrations in Section 3.1.1 were derived. <br /> 4 . Table 2-2 and Appendix B: Table 2-2 lists that the maximum DDX <br /> concentration detected in groundwater collected at SB1084 was 0.2 ug/l. <br /> However, according to Appendix B, DDE was detected at 0.4 ug/l and DDT <br /> at 0.7 ug/1 (DDD was not detected) , which adds up to 1.1 ug/1; and <br /> dieldrin was detected at 0.1 ug/1, not at 0.11 ug/l as indicated in the <br /> table (sample ID: SB1084GWOOIDS, Page 95 in Appendix B) . For <br /> consistency, please revise Table 2-2 to be consistent with the data <br /> presented in the appendices. This comment will also affect Section <br /> 2 .3.1. <br /> 5. Figure 2-1 and Appendix A: The soil sample identification numbers shown <br /> in Figure 2-1 do not match the numbers listed in Appendix A. For <br /> clarity and consistency please include a table listing corresponding <br /> sample numbers or revise Figure 2-1 to refer to the laboratory <br /> identification numbers as follows: <br /> Figure 2-1 ID Appendix A ID Numbers <br /> Numbers <br /> ICFSPS6 SO-007 <br /> ICFSPS7 SO-008 <br /> ICFSPS4 SO-003 <br /> 3 <br />
