Hal Davis 2016 Publication Open-File Report 2016-1066 Reston, Va., USA U.S. Geological Survey https://doi.org/10.3133/ofr20161066 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 measured in 2001. This groundwater model was created to preliminarily characterize trichloroethene transport in the surficial and Cambrian-Ordovician aquifer systems at the Naval Industrial Reserve Ordnance Plant in Fridley, Minnesota. The development of input and output files included in this data release are documented in USGS Open File Report 2016-1066 (https://doi.org/10.3133/ofr20161066). The USGS will support archive users by correcting errors in this data release, and by clarifying. King and Davis (2016, https://doi.org/10.3133/ofr20161066) described the purpose, construction, and limitations of the models in this archive. The archive is broken into parts. Instructions for executing these models are in the ASCII file entitled "readme.txt", which is part of this data release. The USGS, in cooperation with the U.S. Department of the Navy, used a steady-state, uniform-density groundwater flow model (MODFLOW-2000) to simulate measured potentiometric heads in aquifer systems on August 20, 2001; and a transient, single-phase, conservative, non-reactive, miscible transport model (MT3DMS) to simulate trichloroethene concentrations in aquifer systems measured in 2001. Trichloroethene transport was modeled for 3,000 days from June 3, 1993, to August 20, 2001. 19960603 20111231 publication date Complete Not planned -93.36111 -92.92500 45.24722 45.02778 USGS Thesaurus usgsgroundwatermodel MODFLOW2000 MT3DMS Groundwater inlandWaters Groundwater Model Transport Model Volatile Organic Compound Trichloroethane geoscientificInformation environment ISO 19115 Topic Category Groundwater inlandWaters geoscientificInformation environment USGS Metadata Identifier USGS:910a775d-f787-46d2-843b-c7f91f44a90f Geographic Names Information System Minnesota Fridley Anoka County Naval Industrial Reserve Ordnance Plant Cambrian-Ordovician aquifer system surficial aquifer system St. Peter Sandstone St. Peter aquifer Lower St. Peter confining unit Prairie du Chien Group Shakopee aquifer Oneota confining unit Jordan Sandstone Jordan aquifer St. Lawrence Formation St. Lawrence confining unit Tunnel City Group Upper Tunnel City aquifer Lower Tunnel City confining unit Wonewoc Sandstone Wonewoc aquifer Ironton and Galesville Sandstone Franconia Formation Hollandale embayment St. Peter-Prairie du Chien-Jordan aquifer St. Lawrence-Franconia confining unit Ironton-Galesville aquifer Eau Claire confining unit Mount Simon-Hinckley aquifer Mount Simon Sandstone Upper Mount Simon aquifer Middle Mount Simon confining unit Lower Mount Simon aquifer Hinckley Sandstone Solor Church Formation Keweenawan Supergroup Twin Cities aquifer system Twin Cities Metropolitan Area None.
