This data release presents chemical and biological results from an investigation of the uptake of per- and polyfluoroalkyl substances (PFAS) from groundwater contaminated by fire training activities on Cape Cod, Massachusetts conducted from July to August 2019. An exposure experiment was conducted at an a PFAS contaminated site (FTA-1) near the fire training area (FTA). To assess the tissue-specific uptake characteristics of the mixture of PFAS present in the groundwater from the FTA-1 site, a 21-day mobile laboratory exposure experiment was conducted. Details for the groundwater sampling sites and well construction are presented (Table 1). The PFAS mixture concentrations and composition in groundwater and in fish...

The U.S. Geological Survey Toxic Substances Hydrology Program Cape Cod Research site has been the subject of intensive hydrological and geochemical investigations. The site has multiple sources of poly- and perfluoroalkyl substances (PFASs), including perfluorooctane sulfonate (PFOS) and perfluorooctanoate (PFOA), for which the U.S. Environmental Protection Agency has issued health advisories because of potential adverse human health effects. During 2014 and 2015, groundwater contamination by PFASs from a fire-training area and a wastewater treatment facility effluent infiltration beds, located on Joint Base Cape Cod, was assessed by collecting groundwater samples and sediment cores (Figures 1 and 2). The water...

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...
This data release presents chemical and biological results from an investigation of the uptake of per- and polyfluoroalkyl substances (PFAS) from groundwater contaminated by fire training activities on Cape Cod, Massachusetts. Exposure experiments were conducted from August 29 to September 21, 2018 using groundwater from a relatively uncontaminated reference site and a fire training area contaminated site. To assess the uptake characteristics of the PFAS mixtures present in the 2 groundwater sources, 21-day mobile laboratory exposure experiments were conducted using fathead minnows (Pimephales promelas), polar organic chemical integrative samplers, and polyethylene tube samplers. Freshwater mussel (Ligumia subrostrata)...
