A groundwater model was developed to address corrective actions under the WDEQ to provide an understanding of remedial alternatives to prevent off-site migration of contaminated groundwater and LNAPL. A three-dimensional finite-difference groundwater model was used to assist with the design and placement of a groundwater interceptor trench. The model aided in characterizing the subsurface, simulating aquifer layers of various permeability and representing various soil horizons. The model was also used to simulate the effect of existing pumping systems, planned and existing interceptor trenches, wastewater ponds, and creeks. Visual MODFLOW was used to generate the model, which was used in conjunction with mapping programs to create groundwater maps that were incorporated into technical documents.
