Geochemical and Hydrogeological Data Assimilation with Geospatial Modeling Technology
Publication: Journal of Hydrologic Engineering
Volume 14, Issue 11
Abstract
A thorough review and geological characterization of the latest geochemical and hydrogeological data of the A_area and M_area at a superfund site was undertaken in order to determine the nature and extent of contamination. An integrated contaminant plume and geologic structure model was developed. The GIS surface topographic map is overlaid on the integrated model. The results of this study provide basic information to identify current or potential problems caused by the contamination and assist in the evaluation and selection of the remedial action. In addition, this study assimilated input data for groundwater flow and contaminant transport modeling and will tremendously reduce the uncertainty of modeling. The geospatial modeling technology was fully used for construction, interactive visualization, and manipulation of three-dimensional models of complex geologic layers where property (chemical concentration) grids populate.
