The PHS/EHD indicated that it did not consider the estimated carbon <br /> 11 i <br /> content of 1 percent used for the modeling to be conservative. They requested that the <br /> .potential threat to groundwater be reassessed based on carbon contents ranging between <br /> 0.06 and 2.3 percent- <br /> Comment <br /> ercentComment No. 2. PHS/EHD also provided a copy of field notes that were apparently <br /> recorded during the collection of soil samples S 1,S2, and S3 on June 25, 1986.

All analytical results from <br /> groundwater sampling were presented in Appendix B and i summarized in Table 2 of <br /> Revised Remedial Action Plan. <br /> , <br /> ,I <br /> 1:\PJ2WAS00918.D0C-9gIc:3 ' <br /> i <br /> f <br />
