The U.S. Geological Survey (USGS), in cooperation with the Miami Conservancy District, Dayton, Ohio, in 2019 and 2020 investigated the concentrations of per- and polyfluoroalkyl substances (PFAS) and related water chemistry in groundwater from the Great Miami buried-valley aquifer (GM-BVA) of southwestern Ohio. Data in this release include groundwater parameters, including groundwater level, temperature, pH, dissolved oxygen, turbidity, and specific conductance, collected during the 2019-2020 water sampling and comparison data from prior, 1999-2000 sampling of the same wells. The 23 wells used for sampling were identified and sampled previously by the USGS National Water-Quality Assessment Program, starting in 1999,...

This data release presents results of chemical analyses of groundwater sampled during summer and autumn of 2019 and spring of 2020 from 23 wells in the Great Miami buried-valley aquifer (GM-BVA) of southwestern Ohio. Groundwater and quality-control samples were analyzed to determine concentrations of selected per- and polyfluoroalkyl substances (PFAS). Groundwater and related quality-control samples were collected from 22 of 23 wells and analyzed for 24 different PFAS by two different laboratories that used slightly different proprietary isotope-dilution based adaptations of U.S. Environmental Protection Agency (USEPA) method 537.1, referred to as method 1 and method 2. Results from PFAS analysis of groundwater...
The U.S. Geological Survey (USGS) in cooperation with the Miami Conservancy District, Dayton, Ohio, in 2019 and 2020 investigated the occurrence of per- and polyfluoroalkyl substances (PFAS) in groundwater from the Great Miami buried-valley aquifer (GM-BVA) of Southwestern Ohio. The 23 wells used for PFAS sampling were identified and sampled previously by the USGS National Water-Quality Assessment Program to assess the occurrence of a variety of inorganic and organic contaminants in the GM-BVA. Data in this release include tritium and tritium-helium based groundwater-age estimates from the same wells sampled for PFAS,as compiled from Hinkle and others (2010) and McMahon and others (2022). The prior (1999) sampled...

The U.S. Geological Survey (USGS) in cooperation with the Miami Conservancy District, Dayton, Ohio, investigated concentrations of per- and polyfluoroalkyl substances (PFAS) in groundwater from the Great Miami buried-valley aquifer (GM-BVA) of southwestern Ohio in 2019 and 2020. Data in this release include redox (reduction/oxidation) related water-chemistry determinations from groundwater sampled previously in 1999 and 2000 and from groundwater sampled by this study in 2019 and 2020 that include concentrations of dissolved oxygen, sulfate, several nitrogen species, manganese, and iron. The 23 wells used for the sampling were identified and sampled previously by the USGS National Water-Quality Assessment Program...

The U.S. Geological Survey (USGS), in cooperation with the Miami Conservancy District, Dayton, Ohio, in 2019 and 2020 investigated concentrations of per- and polyfluoroalkyl substances (PFAS) in groundwater from the Great Miami buried-valley aquifer (GM-BVA) of southwestern Ohio. Data in this release include reporting limits and detection limits from PFAS analyses of groundwater and quality-control samples collected or prepared by this study, including sequential replicate samples of groundwater, equipment blanks and source-solution blanks prepared before or during groundwater sampling. The 23 wells used for sampling were identified and sampled previously by the USGS National Water-Quality Assessment Program to...

The U.S. Geological Survey (USGS) in cooperation with the Miami Conservancy District, Dayton, Ohio, in 2019 and 2020 collected and analyzed groundwater samples and quality-control samples to describe concentrations of per- and polyfluoroalkyl substances (PFAS) in the Great Miami buried-valley aquifer (GM-BVA) of southwestern Ohio. Data in this release include recoveries of isotopically labeled PFAS surrogate compounds added by the analytical laboratories to quality assure the reported concentrations of PFAS in groundwater and quality-control samples. The 23 wells used for PFAS sampling were identified and sampled previously by the USGS National Water-Quality Assessment Program to assess the concentrations of a variety...

The U.S. Geological Survey (USGS) in cooperation with the Miami Conservancy District, Dayton, Ohio, in 2019 and 2020 collected and analyzed groundwater samples to describe concentrations of per- and polyfluoroalkyl substances (PFAS) in the Great Miami buried-valley aquifer (GM-BVA) of southwestern Ohio. Data in this release include results from PFAS analysis of groundwater samples from 23 wells from parts of the GM-BVA in Butler, Champaign, Clark, Greene, Hamilton, Miami, Montgomery, Shelby and Warren Counties within the Great Miami River, Little Miami River and Whitewater River Basins. The 23 wells used for PFAS sampling were identified and sampled previously by the USGS National Water-Quality Assessment Program...
