2.6 Using Groundwater Transport Models to Determine the Effects of River Infiltration/Exfiltration on CCR Saturation Levels

Flooding of rivers adjacent to Coal Combustion Residual (CCR) impoundments may result in short-term increases in groundwater levels and present the potential for groundwater to contact and/or saturate CCR which is typically located above the water table. This session presents a case study for use of a groundwater flow and transport model for evaluation of intermittent CCR saturation from river flooding and changes in boron concentrations in groundwater which may result.
