MODFLOW6 and MODPATH7 were used to identify streams and other areas potentially affected by PFAS contamination based on particle-tracking flow paths from known PFAS source areas. Reverse particle tracking away from PFAS reconnaissance areas was used to identify potential additional sources of PFAS. The coupled calibrated groundwater flow and particle-tracking transport model provides valuable tools for predicting the relative magnitude and extent of PFAS contamination from onsite legacy source areas. The calibrated model also provides measures of water-level and baseflow observation influence and leverage that can help guide future data collection efforts related to groundwater and surface water sampling for PFAS. The development of the model input and output files included in this data release are documented in the U.S. Geological Survey Open File Report 2022-1112 (https://doi.org/10.3133/ofr20221112)
