Estimating the Extent and Thickness of DNAPL within the A/M Area of the Savannah River Site

摘要

The objective of this study is to refine the current conceptual model for the extent, character, and thickness of DNAPL contamination in the A/M Area. The evaluation is based upon historical records of operations and waste management and on detailed screening of historical groundwater concentrations against solubility limits. The topology of the Green Clay confining zone is used as the primary factor determining DNAPL pool thickness and resulting migration paths.
