Dataset is a model archive containing all relevant files to document and re-run the models that are discussed in the report: Fowler, K.K., 2018, Flood-Inundation Maps for Cedar Creek at 18th Street at Auburn, Indiana: U.S. Geological Survey Scientific Investigations Report 2017-5156.
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,...

Digital flood-inundation maps for selected streams in Stark County were created by the U.S. Geological Survey (USGS) in cooperation with the Muskingum Watershed Conservancy District and the Stark County Commissioners as part of a Federal Emergency Management Agency (FEMA) Flood Insurance Study (FIS). The flood-inundation maps show estimates of the areal extent corresponding to the 1% and 0.2% annual-exceedance probability floods. Flood profiles were computed for the stream reach by means of the one-dimensional step-backwater model.
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...
This dataset contains data tables of laboratory quality-control data associated with environmental samples analyzed for microbiological constituents at the Ohio Water Microbiology Laboratory of the U.S. Geological Survey (USGS). The environmental samples were collected across the United States by USGS National Projects and projects in Water Science Centers. These quality-control data can be used to assess the quality of microbiological data for the associated environmental samples.
These data were released prior to the October 1, 2016 effective date for the USGS’s policy dictating the review, approval, and release of scientific data as referenced in USGS Survey Manual Chapter 502.8 Fundamental Science Practices: Review and Approval of Scientific Data for Release. This data set represents the extent of the Ordovician aquifers in Tennessee and Kentucky.

Digital flood-inundation maps for a 1.9-mile reach of Cedar Creek at 18th Street at Auburn, Indiana, from the First Street Bridge, downstream to the streamgage at 18th Street, then ending approximately 1100 ft downstream of the Baltimore and Ohio railroad bridge, were created by the U.S. Geological Survey (USGS) in cooperation with the Indiana Department of Transportation. The flood-inundation maps, which can be accessed through the USGS Flood Inundation Mapping Science Web site at http://water.usgs.gov/osw/flood_inundation/, depict estimates of the areal extent and depth of flooding corresponding to selected water levels (stages) at the USGS streamgage on Cedar Creek at 18th Street at Auburn, Indiana (station number...
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...
