Mercury concentrations and isotopic compositions in biota and sediments from the Hannibal Pool of the Ohio River

The Hannibal Pool of the Ohio River is heavily industrialized and receives direct effluent discharges from coal power plants, chlor-alkali plants, and sewage treatment facilities. Mercury (Hg) is a contaminant of concern due to the risk of bioaccumulation at wildlife refuges also located within this region. Mercury concentrations and isotopes compositions were measured to assess the levels and source of Hg contamination, respectively within the system. Sediments and waters were measured to define isotopic end members within Hannibal Pool. Heelsplitter mussels, zebra mussels, and prey fish were also analyzed to determine if Hg source signatures were conserved within the food web. These data are a part of a larger study and an associated journal article documented in Integrated Environmental Assessment and Management (https://doi/10.1002/ieam.4308).

Topobathymetric Digital Elevation Model (TBDEM) of the Milwaukee River Estuary, Milwaukee, Wisconsin and adjacent terrestrial and Lake Michigan nearshore coastal areas

This topobathymetric digital elevation model (TBDEM) mosaic represents the topography and bathymetry for the Milwaukee River Estuary in Milwaukee, Wisconsin and adjacent terrestrial and Lake Michigan nearshore coastal areas. The TBDEM was produced in support of modeling and for developing a physical habitat framework to help with understanding the effects from multidirectional currents and seiche effects associated with the mixing of river flows with Lake Michigan backwater.  The TBDEM mosaic is built off existing terrestrial, nearshore, and estuary frameworks developed for other areas around the Great Lakes and the Milwaukee River Harbor. Ranging from 2008-2015, land elevations derived from lidar and historic topographic surveys and bathymetric multibeam sonar were used to generate the seamless Milwaukee River Estuary TBDEM from four different data frameworks: (1) 2015 Milwaukee River Estuary Bathymetry (Dow, 2018), (2) 2015 SEWRPC Topographic LIDAR for Southeast, Wisconsin (Office for Coastal Management (OCM) Partners, 2018), (3) 2012  NOAA Digital Coast Topographic and Bathymetric LIDAR (OCM, 2017), and (4) 2008  NOAA Digital Coast Topographic and Bathymetric LIDAR (OCM, 2008). The TBDEM is provided as a 0.6-meter resolution raster dataset in GeoTIFF format.

Discharge records and sand extents along the Colorado River between Glen Canyon Dam and Phantom Ranch, Arizona

The data contained in these tables detail the areal extent of exposed sand, in square meters, along the Colorado River between Glen Canyon Dam, Arizona, and Bright Angel Creek, Arizona, within Glen Canyon National Recreation Area and Grand Canyon National Park. Sand exposure areas are provided as a function of Colorado River discharge, as measured at Lees Ferry, Arizona, in increments of 1000 cubic feet per second. Exposed sand extents are subdivided into mapped and unmapped sand areas; at Colorado River discharge; at flows below 8,000 cubic feet per second, the total extent of exposed sand can be estimated as the sum of field-mapped sand and that sand which was unmapped, but estimated to be present across the study area. At discharges at or above 8,000 cubic feet per second, all unmapped sand is inundated. Cells highlighted in green correspond to inundation extents derived from hydraulic modeling along the Colorado River in Grand Canyon, and linear interpolation was performed to estimate exposed sand extent between these discrete modeling discharges.

Water Quality and Bed-sediment Quality from Mountain Creek Lake and two stream sites near Grand Prairie, Texas, 2019

Mountain Creek Lake is a reservoir in north Texas 8 miles southwest of Dallas, Texas where historical contamination by polychlorinated biphenyl compounds (PCBs) and other organic contaminants has been reported. There was a need to reassess concentrations of contaminates of organic and inorganic compounds in the reservoir. In cooperation with the City of Dallas, the U.S. Geological Survey (USGS) sampled Mountain Creek Lake and two downstream stream sites over two sampling events. The study area consisted of seven sites on Mountain Creek Lake, one site on the Trinity River, and one site on Mountain Creek. Water-column and bed-sediment samples were collected at each site in June and August of 2019.
Water-quality field properties (water temperature, dissolved-oxygen concentration, pH, specific conductance, and turbidity) were measured in the field at each sampling site by using a Xylem YSI EXO2 sonde. Water-column samples were collected by using a peristaltic pump to collect composite water samples that were analyzed for 32 major and trace elements, 6 nutrients, 68 volatile organic compounds (VOCs), alkalinity, dissolved solids (DS), and turbidity. Bed-sediment samples were collected by using a gravity corer for lake sites and grab samples for stream sites. Bed-sediment samples were analyzed for 50 major and trace elements, 17 polycyclic aromatic hydrocarbons (PAHs), 9 PCBs, and 66 VOCs.
The USGS National Water Quality Laboratory in Denver, Colorado analyzed water samples for major and trace elements, nutrients, alkalinity, dissolved solids, and turbidity. RTI Laboratories in Detroit, Michigan analyzed water samples for VOCs. Bed-sediment samples were analyzed by RTI Laboratories for PAHs, PCBs, and VOCs. AGAT Laboratories analyzed bed-sediment samples for major and trace elements.
This Data Release documents the results of the water and bed-sediment sample analyses.

Per- and polyfluoroalkyl substance concentrations, age estimates, redox categories, and related data for groundwater from the Great Miami buried-valley aquifer, southwestern Ohio, 2019–20

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 samples and quality-control samples, including sequential replicate samples and field blanks are presented in this data release. Reporting and detection limits for analyses of individual PFAS and recovery data for isotopically labeled surrogate compounds added to each sample by the analyzing laboratory, are also included in the data release.  The GM-BVA is a glacial outwash and alluvial fill aquifer that is the sole source of water supply for much of the region. The study was performed by the U.S. Geological Survey, in cooperation with the Miami Conservancy District, Dayton, Ohio.  
This data release includes details of the sampled wells, tritium-helium-3 and tritium-based estimates of groundwater age from prior (1999 and 2000) and current (2019-2020) groundwater samples, and redox (reduction/oxidation) classifications and related water-quality constituent concentrations from groundwater samples collected in 1999, 2000, 2019 and 2020 from the same wells sampled by this effort for PFAS. Field groundwater-quality parameters measured from the sampled wells in 1999–2000 and in 2019–2020 groundwater sample collection are also presented.

Geospatial datasets developed for a groundwater-flow model of the Denver Basin aquifer system, Colorado

In 2004, the U.S. Geological Survey initiated a large-scale regional study of the Denver Basin aquifer system to evaluate the hydrologic effects of continued pumping and document an updated groundwater-flow model useful for appraisal of hydrologic conditions (Paschke, 2011). This data release includes spatial datasets used as input for a three-dimensional groundwater-flow model of the Denver Basin aquifer system. Spatial datasets were developed for six Denver Basin bedrock aquifers and five intervening confining units including, from oldest to youngest, the Laramie-Fox Hills aquifer (KLF), Laramie confining unit (KLC), lower Arapahoe aquifer (LKA), Arapahoe confining unit (KAC), upper Arapahoe aquifer (UKA), Denver lower confining unit (TKDLC), Denver aquifer (TKD),  Denver upper confining unit (TKDUC), lower Dawson aquifer (LTDW), Dawson confining unit (TDWC), and upper Dawson aquifer (UTDW). Maps of the base altitude and lateral extent of each aquifer were developed for the 11 aquifer and confining units to define the hydrogeologic framework for the model. The BasePoints.zip folder contains 11 point shapefiles of the data points for altitude of the base of each bedrock aquifer and confining unit and one shapefile with locations of wells in the Denver Basin having geophysical logs ("PP1770_seo_geologs_points"). The "BaseContours.zip" folder contains 11 polyline shapefiles of generalized lines of equal base altitude for each bedrock aquifer and confining unit derived from the base-altitude points, and the "Extents.zip" folder contains 11 polygon shapefiles representing the extent of each aquifer and confining unit. Maps of silt-plus-sand thickness were developed for the six bedrock aquifers and were used to estimate hydraulic conductivity and specific yield in the groundwater-flow model. The "SandPoints.zip" folder contains six point shapefiles of data points for silt-plus-sand thickness of each bedrock aquifer, and the "SandContours.zip" folder contains six polyline shapefiles of generalized lines of equal silt-plus-sand thickness derived from the silt-plus-sand thickness points. Shapefiles in the zipped folders are named using the abbreviation or name of the aquifer or confining unit as shown on Table A2 of Paschke (2011).

Aqueous and Solid Phase Chemistry of Sequestration and Re-oxidation of Chromium in Experimental Microcosms with Sand and Sediment from Hinkley, CA

Cr(VI) contaminated groundwater at Hinkley is undergoing bioremediation using added ethanol as a reductant in a volume of the aquifer defined as the In-situ Reduction Zone (IRZ). This treatment effectively reduces Cr(VI) to Cr(III) which is rapidly sequestered by sorption to aquifer particle surfaces and by co-precipitation within iron or manganese bearing minerals forming in place as reduction proceeds. Successful mitigation of the extant Cr(VI) plume is projected to require 90 to 220 years, at which time ethanol loading will likely cease. This projection assumes that Cr(VI) removal is permanent and that no Cr(III) will oxidize back to Cr(VI) in the event of changing hydrological conditions resulting in oxygen rich water re-entering the IRZ.
We undertook laboratory microcosm experiments to explore the process of reductive sequestration and the potential for re-oxidation. In reduction experiments, batch microcosms were prepared with materials from sites within the aquifer, up-gradient of the Cr(VI) regulatory plume. Control microcosms were prepared using cleaned quartz sand and iron (Fe)-coated sand. Unfiltered Mojave River groundwater and an added tracer of 50Cr were reacted with microcosm materials for two years. During this time, bio-reduction was stimulated by repeated additions of diluted ethanol to maintain reduced conditions within appropriate ranges; avoiding sulfate reducing or methanogenic conditions as much as possible while mimicking field conditions.
To evaluate the potential for re-oxidation of Cr(III), additional batch microcosms of site materials and mixtures of Fe- and Mn-coated sand were first reduced for more than 1 year and subsequently exposed to air and allowed to oxidize for up to 2 years. Cr(VI) was released during oxidation of all materials. The amount of Cr(VI) released and when it was released varied among substrates. Our results showed that the nature and locus of Cr(III) sequestration influenced it’s vulnerability to re-oxidation back to Cr(VI).
This data release includes three tables in *.csv format with the preliminary experiment (preliminary.csv), reduction experiment (reduction.csv), and the oxidation experiment (oxidation.csv) along with a Google Earth file of the well sites (wells.kmz).

EXO2 vertical point water-quality measurements at unnamed north lake near Bemidji, Minnesota, 2019

These data were collected in coordination with the U.S. Geological Survey Hydrogeophysics Branch for the National Crude Oil Spill Fate and Natural Attenuation Research Site. An EXO2 multi-parameter sonde was used to vertically characterize water quality at point locations around the perimeter of the north unnamed lake, and in area of the lake suspected to contain a hydrocarbon plume.  Measurements were taken from a kayak using Hypack 2017a to navigate and set target points.  Data collected includes barometric pressure, dissolved oxygen, specific conductance, turbidity, pH, and water temperature.  At each location and specific depth there were typically multiple measurements made, especially in the organic sediments when turbidity was sometimes erratic and dissolved oxygen took time to stabilize.  Standard deviation was calculated for each measured parameter at a particular station and depth. 
These data are provided in two formats: a CSV file named EXO2_Vertical_WQ.csv, and in the Environmental Systems Research Institute (ESRI) shapefile format consisting of a group of files that have been compressed into a zip archive that is named EXO2_Vertical_WQ_shapefile.zip.
