Layered geospatial PDF 7.5 Minute Quadrangle Map. Layers of geospatial data include orthoimagery, roads, grids, geographic names, elevation contours, hydrography, and other selected map features. This map is derived from GIS (geospatial information system) data. It represents a repackaging of GIS data in traditional map form, not creation of new information. The geospatial data in this map are from selected National Map data holdings and other government sources.

These vector contour lines are derived from the 3D Elevation Program using automated and semi-automated processes. They were created to support 1:24,000-scale CONUS and Hawaii, 1:25,000-scale Alaska, and 1:20,000-scale Puerto Rico / US Virgin Island topographic map products, but are also published in this GIS vector format. Contour intervals are assigned by 7.5-minute quadrangle, so this vector dataset is not visually seamless across quadrangle boundaries. The vector lines have elevation attributes (in feet above mean sea level on NAVD88), but this dataset does not carry line symbols or annotation.

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, 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 in 2019 and 2020. Data in this release include selected characteristics of wells that were used for sampling, as compiled from water-well log reports in a publicly available database from the Ohio Department of Natural Resources and well information stored in the U.S. Geological Survey's Groundwater Site Inventory database. The 23 wells used for sampling were identified and sampled previously by the USGS National Water-Quality...
