Abstract

The focus of the presentstudy was centered on the modeling analysis to support the Permeable Reactive Barrier (PRB) design. The flow model formulated to simulate the Permeable Reactive Barrier System integrated the available geologic, hydro geologic and geo-chemical data from numerous recent installations to simulate a subsurface ground water scenario.

Different generic cases that a PRB system would fall into were identified based on its utility and aquifer conditions and then employed to produce different model adaptations. The different simulation codes and interfaces were evaluated, and the most expedient of them was used to simulate the Model.

The simulations were then used to study the sensitivity of different parameters and identify those that were critical to the design of the system. Design curves, devised to aid the design of a barrier, were verified with the residence time curves mapped for the same parameters. The results of the sensitivity analysis and the developed design curves were used to arrive at a uniform procedure for the design of a Continuous Configuration Barrier System.

The procedure was appraised by working through the design of a Permeable Reactive Barrier at a GW contaminated site located in the Piedmont Province of the Appalachian Highlands in New Jersey.
