A Discrete Fracture Network (DFN) model was created using FracManRTM to evaluate hydraulic capture of an existing pump and treat system at a former PCB transfer facility in Smithville Ontario. A sensitivity analysis of the DFN model to varying model input parameters was carried out to demonstrate to site investigators what aspects of the fracture network are most influential in determining the aerial and vertical extent of capture.; Two separate three level factorial designs were used to carry out the sensitivity analysis. The first evaluated the effect of changing bedding plane fracture (BPF) parameters P32, mean aperture and mean fracture size on the area and depth of capture. The second evaluated the effect of changing VF parameters P32, mean aperture and termination % on area and depth of capture.; Analysis of Variance tables and regression analysis were utilized to interpret each of the factorial design analyses.
