Project Overview
The fate and transport of contaminants in the subsurface requires knowledge of the hydrogeologic system. Site characterization typically involves the collection of various data sets needed to create a conceptual model that represents what´s known about contaminant migration in the subsurface at a particular site. Hydrogeologic Data Fusion is a mathematical tool that can be used to combine various types of geophysical, geologic, and hydrologic data from different types of sensors to estimate geologic and hydrogeologic properties. It can be especially useful at hazardous waste sites where the hydrology, geology, or contaminant distribution is significantly complex such that groundwater modeling is required to enable a reasonable and accurate prediction of subsurface conditions.

Technology Description
Hydrogeologic Data Fusion is used in conjunction with standard ground- water flow models, such as MODFLOW, to provide a better method for estimating the model parameters. Hydrogeologic Data Fusion is superior to manual calibration because it uses a physical basis for parameter estimation. It also results in the quantification of parameter uncertainty, parameter correlation, and uncertainty in contaminant transport. The Hydrogeologic Data Fusion product developed under DOE funding is called DFW/VAM3DF and is available for use by government contractors and governmental organizations. HydroFACT is a commercial offering with more limited capabilities, which was developed by Fusion and Control Technology, Inc.
