Using Fate and Transport Models for Predicting Barrier Performance of a Liquid Activated Carbon
The use and consideration of injecting a liquid activated carbon into an aquifer to create a long-term barrier is growing. The proper design and implementation of a LAC or other carbon barrier could only be properly accomplished by understanding the underlying competitive-sorption and transport processes of each organic contaminant involved. Successful understanding of competitive sorption/desorption phenomena allows appropriate dosing and life-cycle design as wells as when performance at monitoring wells should be expected. This talk will present examples of the use of modeling to predict, calibrate, and manage retardation based and passive plume management strategies using LAC. A complete understanding requires consideration of competing sorption of organics, including predicting impact from inter-barrier transformation of parent to daughter products. This approach can allow for a high degree of predictability which is helpful not only for site owners and regulators to predict results, but also to tune monitoring programs for cost saving.
