Summary

The U.S. Geological Survey, in cooperation with the U.S. Department of the Navy, developed several 3-D groundwater flow models for used with MODFLOW-2005, MODFLOW-NWT, and SEAWAT model codes to evaluate variable-density groundwater flow and contaminant transport in Operable Unit 1 on Naval Base Kitsap in Keyport, Washington. Chlorinated volatile organic compounds (CVOCs) have migrated to groundwater beneath a former 9-acre landfill at Operable Unit 1 (OU-1). The three predominant ground-water contaminants are the chloroethene compounds trichloroethene (TCE), cis-1,2-dichloroethene (cis-DCE), and vinyl chloride (VC). A need for remedial action was identified because some of the contaminants present a potential risk to humans primarily [...]

Purpose

The models were created to simulate the pattern and rate of groundwater flow and to estimate values of hydraulic properties of the hydrogeologic units that control the flow of groundwater. The variable-density groundwater flow and contaminant transport models were used to simulate the migration of CVOCs from localized sources at Operable Unit 1 (OU-1) on Naval Base Kitsap. Applications of additional model simulations show the effects of tidal fluctuations and biodegradation on the migration of CVOCs and predict the fate of contaminants at OU-1 after three hypothesized reductions of localized sources through potential remedial activities. The development of the model input and output files included in this data release are documented in the U.S. Geological Survey Scientific Investigations Report 2020-5066 (https://doi.org/10.3133/sir20205066)
