feet bgs (SB1117SOOOIDS). Please revise Section 2.2.3.4, Table 2-2, Table 2-3, and Figure 2-2 to accurately present the data. 5. Specific Comment 4: The response is adequate. However, it raises new issues. Since the response states that the duplicate groundwater sample was re-analyzed out of holding time, please flag all data points in Appendix B affected by this problem as "J", or estimated, and provide a footnote to explain that the "J" flag was due to holding time exceedances. The response and Figure 2-3 correctly present the concentrations of DDX and dieldrin in the duplicate sample from SB1084 at 23 feet bgs. However, the text in Section 2.3.2 and Table 2-5 should be clarified to present the results of the primary and duplicate samples separately and correctly. For clarity,please consider changing the sampling location in Table 2-5 to SB 1084 FD and add a footnote to explain that FD =field duplicate. In addition, Figure 2-3 omits the data from the primary sample. Please post the data from SB I 084GWOO INS (all non-detected) on Figure 2-3. 6. Specific Comment 7: The response is not adequate. The response states that "The figure shows only detected analytes, as noted in the bottom lefthand corner of the figure." However, when Figure 2-2 was revised the note was removed. Please revise Figure 2-2 to include the note informing the readers that only detected analytes are presented. 7. Specific Comment 10: The response is not adequate. The response states that a summary table will present, among other items, relevant exposure point concentrations. While the new Table 3-1 presents the other items detailed in the response, it does not present relevant exposure point concentrations. Please revise Table 3-1 to indicate which concentrations from the table were used for exposure point concentrations or present a separate table of exposure point concentrations. 8. Specific Comment 19: The response is not adequate. The response states that the storm drain line will be added to Figure 2-2. The storm drain line was added but it is not called out on the figure or explained in the legend. Please provide a callout on the figure or explain the storm drain line in the legend of Figure 2-2. This comment also applies to Figure 2-4. Minor Comments 1. Some of the EPA's comments were not transcribed accurately to the table. This may become confusing when readers attempt to verify that the comments were adequately addressed. Please make the following changes to the Response to Comments table in the next version of this document: a) Specific Comment 1, line 4: change 2,588 to 2.588 2
