Description

Reactive Transport Modeling of Closure-in-Place with Intersecting Groundwater and Remedial Actions: Part II, Results and Meaning Authors Mr. Bruce Hensel - United States - Electric Power Research Institute Dr. Jason James - United States - Exponent Dr. Olivia Paradis - United States - Exponent Dr. Rachel Kelly - United States - Exponent Dr. Walter McNab - United States - Exponent Abstract This EPRI research project was initiated to better understand two objectives: • How is mobility of inorganic constituents affected by the intersection of groundwater with coal combustion product ponds and landfills under varying geologic and redox conditions? • How do corrective actions after closure-in-place affect constituent mobility? The modeling was described in Part I. In this part of the presentation, we will examine the results and how they advance our understanding of the environmental implications from closure in place (CIP) when there is intersecting groundwater and when remediation is implemented to control release of contaminants. These results, when considered with previous EPRI closure research, explain why a site-specific approach to closure decisions is important for minimizing risk to the public.
