Summary

The U.S. Geological Survey, in cooperation with the Air Force Civil Engineer Center, developed a numerical, steady-state regional model, using MODFLOW-2005, to evaluate current (2010) conditions and the potential effects of future (2030) groundwater withdrawals on water levels, streamflows, hydraulic gradients, and advective transport near the Joint Base Cape Cod (JBCC). Two numerical models were used in this analysis. An existing two-dimensional (one layer) model (termed the “coast model”), developed as part of a previous investigation of the potential effects of sea-level rise on the Cape Cod aquifer system (https://doi.org/10.3133/sir20165058), simulates the position of the freshwater/saltwater interface by using MODFLOW-2005 with [...]

Purpose

The purpose of the model is to improve the understanding of the hydrologic system and the physical transport of contaminants in the aquifer and determine the effects of future pumping and return flow on the aquifer system, including changes in water levels, streamflows, hydraulic gradients, and advective-transport patterns within and near the JBCC. The model also will provide a regional-scale tool to ensure (1) that local-scale models used in the design and evaluation of remedial systems are linked to a regional model that is, in turn, informed by the most recent hydrologic and lithologic data and (2) that, as local communities address their growing need for potable water, an updated regional model is available to evaluate the effects of contaminants emanating from JBCC on the water resources of western Cape Cod. The development of the model input and output files included in this data release is documented in the U.S. Geological Survey Scientific Investigations Report 2018-5139 (https://doi.org/10.3133/sir20185139)
