A detailed description of the uppermost aquifer is included in the Resource Conservation and Recovery Act (RCRA) Part B post-closure care permit application for the F-Area HWMF submitted to SCDHEC in December 1990. Sampling and analysis are conducted as required by section IIIC.H.6 at the intervals specified in permit sections IIIC.H.10 and Appendix IIIC-D for the constituents specified in Appendix IIIC-D. Groundwater quality is compared to the GWPS list in section IIIC.H.1 and Appendix IIIC-A
