FEMWATER 50 year simulation of flow and transport of contaminants at a DoD Installation in East Texas. This model includes the simulation of the release of a TCE spill from a large chemical storage tank. Contaminants move through the vadose zone and into groundwater which moves through the subsurface from recharge zone to discharge zone in a flowpath direction from the base edge to a river. This simulation was highlighted in a video about the DoD Groundwater Modeling System (GMS). The video was entered into DoD Accomplishments of 1998 and received first place: Army Corps of Engineers-Waterways Experiment Station (ACE-WES), (January 15-April 22, 1998).
