MODFLOW 2000 and MT3DMS models of potentiometric head and trichloroethene concentration at the Naval Industrial Reserve Ordnance Plant, Fridley, Minnesota

This model is a preliminary characterization of trichloroethene transport in the surficial and Cambrian-Ordovician aquifer systems at the Naval Industrial Reserve Ordnance Plant in Fridley, Minnesota. The characterization first considered 2001 conditions using a MODFLOW and MT3DMS, followed by an application of this 2001 model to 2011 conditions. The U.S. Geological Survey (USGS), in cooperation with the U.S. Department of the Navy, used the steady-state, uniform-density groundwater flow model MODFLOW to calculate potentiometric heads in aquifer systems on August 20, 2001; and the single-phase, conservative, non-reactive, miscible transport model MT3DMS to calculate trichloroethene concentrations in aquifer systems...

Geodatabase of the datasets used to represent the four aquifer subunits of the Cambrian-Ordovician aquifer system, Illinois, Iowa, Michigan, Minnesota, and Wisconsin

These data were released prior to the October 1, 2016 effective date for the USGS’s policy dictating the review, approval, and release of scientific data as referenced in USGS Survey Manual Chapter 502.8 Fundamental Science Practices: Review and Approval of Scientific Data for Release. This geodatabase includes spatial datasets that represent the Cambrian-Ordovician aquifer system in the States of Wisconsin, Michigan, Minnesota, Iowa, and Illinois. Included are: (1) a polygon dataset that represents the aquifer system extent, (2) raster datasets for the altitude of each aquifer subunit, (3) altitude, or if applicable, thickness contours used to generate the surface rasters, (4) georeferenced images of the figures...
