This U.S. Geological Survey (USGS) Data Release is focused on the geochemistry of wells within the oil zone and groundwater monitoring wells away from the oiled zone at the National Crude Oil Spill Fate and Natural Attenuation Research Site, Bemidji MN (USA) from 1985-2015. The site located in Beltrami County is where a high-pressure pipeline carrying crude oil burst in 1979 and spilled approximately 1.7 million liters (10,700 barrels) of crude oil into glacial outwash deposits. Researchers and scientists from government agencies, academic institutions, the regulatory community, and private companies have conducted extensive investigations of groundwater geochemistry in hopes of understanding the evolution of plumes...

The Barrier Island Comprehensive Monitoring (BICM) program was developed by Louisiana’s Coastal Protection Restoration Authority (CPRA) and is implemented as a component of the System Wide Assessment and Monitoring (SWAMP) program. The program uses both historical data and contemporary data collections to assess and monitor changes in the aerial and subaqueous extent of islands, habitat types, sediment texture and geotechnical properties, environmental processes, and vegetation composition. Examples of BICM datasets include still and video aerial photography for documenting shoreline changes, shoreline positions, habitat mapping, land change analyses, light detection and ranging (lidar) surveys for topographic elevations,...

Hydraulic fracturing is a treatment method used to stimulate production from oil and gas wells. Hydraulic fracturing involves injection of treatment fluids mixed with propping agents under high pressure into perforated portions of the wellbore. This method causes the reservoir rocks to fracture and the hydraulic fracturing fluids and propping agents to enter the fractures. Subsequently, the injected propping agents remain in the fractures while the oil, gas and(or) water flows back to the well head at the surface. This dataset is a compilation of information on the types and amounts of treatment fluids applied to oil and gas onshore wells that were hydraulically fractured in the United States from 2015 through 2019....

This U.S. Geological Survey (USGS) Data Release provides concentrations from groundwater and soil extracts for iron (Fe), barium (Ba), strontium (Sr), cobalt (Co), and nickel (Ni). Groundwater analyses for pH and alkalinity are also included. Samples were collected at the National Crude Oil Spill Fate and Natural Attenuation Research Site, near Bemidji MN (USA) between 2009-2019. The site is in Beltrami County, where a high-pressure pipeline carrying crude oil burst in 1979 and spilled approximately 1.7 million liters (10,700 barrels) into glacial outwash deposits. A trace element plume occurred at the site, in which concentrations of Fe, Co, Ni, Ba, and Sr were mobilized from the sediments into the groundwater....
This data release provides a recursive-estimation framework to infer groundwater/surface-water exchange based on temperature time series collected at different vertical depths below the sediment/water interface. A heat-transport problem was formulated as a state-space model (SSM), in which the spatial derivatives in the convection/conduction equation are approximated using finite differences. The SSM is calibrated to estimate time-varying specific discharge using the Extended Kalman Filter (EKF) and Extended Rauch-Tung-Striebel Smoother (ERTSS) algorithms. This data release contains both algorithms, synthetic and field-experimental data, as well as VFLUX model results (Neversink_obs.csv, VFLUX_results.csv) used...

This data release contains appendix C1 and appendix C2 for the USGS Scientific Investigations Report (SIR) titled Hydrologic and Geochemical Characterization of the Petaluma River Watershed, Sonoma County, California. Appendix C1 contains selected chemical and physical properties and inorganic constituents in samples from selected springs, and wells, Petaluma Valley watershed, Sonoma County, California, 1959-2015. Samples are presented from 66 groundwater wells, 3 springs, and 2 surface-water sites. Data samples were collected by the U.S. Geological Survey (USGS), California Department of Water Resources (CDWR), California Department of Health Services (CDPH), and the City of Petaluma as part of the study.
