In 1968, the Missouri Geological Survey (MGS) established the Operation Basement program to address three objectives: a) to obtain drill hole and underground mining data relative to the structure and composition of the buried Precambrian basement; b) to expand mapping in the Precambrian outcrop area and conduct research related to Precambrian geology and mineral resources; and c) to publish the results of the first two objectives in the Contribution to Precambrian Geology series (Kisvarsanyi, 1976). The database presented here represents the first of those objectives. It was originally compiled in close cooperation with exploration and mining companies operating in Missouri, who provided drillhole data, core and...

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...

An investigation was completed by the U.S. Geological Survey in cooperation with the Indiana Office of Community and Rural Affairs that found 1,132 transportation and utility assets in Indiana are vulnerable to fluvial erosion hazards due to close proximity to actively migrating streams. Locations of transportation assets (bridges, roadways, and railroad lines) and selected utility assets (high-capacity overhead power-transmission lines, underground pipelines, water treatment facilities, and in-channel dams) were determined using aerial imagery hosted by the Google Earth platform. Identified assets were aggregated by stream reach, county, and class. The contents of this data release include (1) a comma-delimited...

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...

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...
