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...

Digital data from previous USGS hydrogeologic studies of the Cambrian-Ordovician aquifer system in the northern Midwest, United States

This dataset captures in digital form previously published maps showing the inferred extent and subsurface elevation of several Paleozoic consolidated rock units in the northern Midwest of the United States. Data released here were published as figures within a U.S. Geological Survey (USGS) Water Mission Area report documenting results from a study of the regional hydrogeology and ground-water quality of the Cambrian-Ordovician aquifer system in the northern Midwest. This study was part of the USGS national Regional Aquifer-System Analysis (RASA) Program. Sandstone and carbonate rocks of Cambrian and Ordovician age compose much of the sedimentary rocks overlying the Precambrian basement in the northern Midwest and...
