Evaluation of Modeling for Groundwater Flow and Tetrachloroethylene Transport in the Milford-Souhegan Glacial-Drift Aquifer at the Savage Municipal Well Superfund Site, Milford, New Hampshire, 2011

By Philip T. Harte

Thumbnail of and link to report PDF (750 KB)Introduction

The U.S. Geological Survey and the New Hampshire Department of Environmental Services entered into a cooperative agreement to assist in the evaluation of remedy simulations of the MSGD aquifer that are being performed by various parties to track the remedial progress of the PCE plume. This report summarizes findings from this evaluation. Topics covered include description of groundwater flow and transport models used in the study of the Savage Superfund site (section 2), evaluation of models and their results (section 3), testing of several new simulations (section 4), an assessment of the representation of models to simulate field conditions (section 5), and an assessment of models as a tool in remedial operational decision making (section 6).
