The organic composition of produced waters (flowback and formation waters) from the Bakken Formation and the Three Forks Formation in the Williston Basin, North Dakota were examined in this study in order to aid in the remediation of surface contamination due to spills during transport and help develop treatment methods for recycling. Twelve produced water samples were collected from wells in the Bakken and Three Forks Formations at the well head and analyzed for non-purgable dissolved organic carbon (NPDOC), acetate, and extractable hydrocarbons. NPDOC and acetate concentrations from sampled wells from ranged from 33-190 milligrams per liter (mg/L) and 16-40 mg/L, respectively. Concentrations of individual extractable...

The goal of this study was to develop a suite of inter-related water quality monitoring approaches capable of modeling and estimating the spatial and temporal gradients of particulate and dissolved total mercury (THg) concentration and particulate and dissolved methyl mercury (MeHg) concentration in surface waters across the Sacramento / San Joaquin River Delta (SSJRD). This suite of monitoring approaches included: a) data collection at fixed continuous monitoring stations (CMS) outfitted with in-situ sensors, b) spatial mapping using boat-mounted, flow-through, sensors and c) satellite-based remote sensing. The focus of this specific Child Page is to present all data collected during the underway boat mapping component...

Bacterial Data include results of incubations of lakewater bacteria with dissolved organic matter extracted from Colorado glacier or rock glacier outflows in 2015. Cells were counted pre- and post- incubations. The “Counts” tab is the number of cells counted in each view of the microscope using the acridine orange method. “C Calculations” tab is the calculation of carbon as bacterial biomass from cell counts. ”Change in cell counts” is the difference in the number of bacterial cells from the pre-incubation microbial culture and in each assay bottle after the biological oxygen demand incubation. The third tab, “Carbon use efficiency” is calculated as the amount of DOM from oxygen demand assays converted to microbial...
Bed sediment samples were collected in San Pablo Bay and Grizzly Bays on eight days from June through November 2019, to analyze for sediment properties including bulk density, particle size distribution, and percent organic carbon. Sediment samples were collected from a small vessel near pre-established USGS instrument moorings using a Gomex box corer that was subsampled with three push cores (37 mm in diameter) per Gomex core. Six subsamples were collected from the top 5 centimeters (cm) of each push core, a few push cores included the top 8 cm. The top two subsamples were each 0.5 cm thick, and all following subsamples were each 1 cm thick. Push core samples from the first, third, and fifth centimeter depth were...

In crude-oil-contaminant plumes the dissolved organic carbon (DOC) is mainly hydrocarbon degradation intermediates only partly quantified by the diesel range total petroleum hydrocarbon (TPHd) method. To understand potential biological effects of degradation intermediates we tested three fractions of DOC: (1) solid phase extract (HLB); (2) dichloromethane (DCM-total) extract used in TPHd; and (3) DCM extract with hydrocarbons isolated by silica gel cleanup (DCM-SGC). Bioactivity of extracts from five wells spanning a range of DOC was tested using an in vitro multiplex reporter system that evaluates modulation of activity of 46 transcription factors; extracts were evaluated at concentrations equivalent to the well...

This U.S. Geological Survey (USGS) Data Release is focused on the geochemistry of wastewater (including flowback and produced water) samples, co-produced with natural gas, collected from the Marcellus Shale Energy and Environment Laboratory (MSEEL) site. MSEEL is a long-term field site and laboratory at the Northeast Natural Energy LLC (NNE) production facility, adjacent to the Monongahela River, located in western Monongalia County, West Virginia, USA. NNE began drilling two horizontal production wells, MIP (Morgantown Industrial Park) -5H and MIP-3H, in the Marcellus Shale in 2014. The wells were completed in December 2015. Large volumes of wastewater are generated with natural gas production. These wastewaters...
Concentrations of particulate organic carbon (POC) and dissolved organic carbon (DOC), which together comprise total organic carbon, were measured in a reconnaissance study at sampling sites in the Upper Klamath River, Lost River, and Klamath Straits Drain in 2013–16. In addition, data for total nitrogen and chlorophyll a were collected. Optical absorbance and fluorescence properties of dissolved organic matter (DOM), which contains DOC, also were analyzed. Excitation-Emission matrices (EEMs) were produced for each sample and full absorbance spectra. The EEMs were compiled and key data points and regions of the spectra were extracted from each site. Parallel factor analysis was used to decompose the optical fluorescence...

This U.S. Geological Survey (USGS) Data Release describes field methods, lab methods, and data for groundwater and soil gas samples collected in the vicinity of the Red Hill Bulk Fuel Storage Facility, O‘ahu, Hawai‘i, from September 2022 through April 2023. The Red Hill facility consists of 20 underground fuel storage tanks that can each hold approximately 12.5 million gallons of fuel and are connected through a network of service tunnels and fuel pipelines. The data in this release were collected to understand better the distribution and directional flow of ancient carbon from past petroleum releases in the subsurface at the Red Hill Bulk Fuel Storage Facility. Table 1 of this data release contains site and sample...
The U.S. Geological Survey collected groundwater samples from 537 domestic wells for pharmaceutical compounds between 2014 and 2021 from 9 different study units. These wells were sampled as part of the California State Water Resources Control Board Groundwater Ambient Monitoring and Assessment (GAMA) Program Priority Basin Project’s assessment of the quality of groundwater resources used for domestic drinking water supply. The 9 study units are in parts of the San Joaquin Valley, Sacramento Valley, Sierra Nevada Foothills, and the Southern California Desert basins where domestic wells are extensively used for drinking water supply. The well selection for the study units were selected by using a grid-based approach...
This data release presents data that were collected as part of a larger effort to refine knowledge pertaining to the origin, composition, and seasonality of dissolved organic matter in lakes. This work was part of an international collaborative effort with the Global Lake Ecological Observatory Network (GLEON). Water samples were collected monthly during 2021 and shipped to GLEON for determination of dissolved organic matter. In conjunction with each monthly sample event, several water-quality variables and ice thickness were measured. Data from this collaborative study will be used to understand how the origin and composition of dissolved organic matter varies through time.

Oklahoma State University South-Central Research Station (SCRS) was used to conduct research to understand the chemical composition of various water types and their potential environmental and human health effects. The study area provided the opportunity to study five water types: (1) receiving surface water (Washita River), (2) urban stormwater, (3) wastewater treatment plant effluent used for irrigation, (4) rain-induced runoff from an effluent-irrigated cornfield, and (5) rain-induced runoff from a dryland cornfield. Fifteen water samples were collected from August 2018 to October 2019. In addition, two composite above ground whole-corn plant samples (i.e., stem, leaves, grain) were collected from the effluent...
This dataset presents the results of passive water sampling conducted at 2 sites in 2013 and 3 sites in 2014 in Lake Mead National Recreational Area. Polar Organic Chemical Integrative Samplers (POCIS) and Semipermeable Membrane Devices (SPMDs) were deployed in Las Vegas Bay and Overton Arm in 2013 and Las Vegas Bay, Boulder Basin, and Overton Arm in 2014. The samplers were analyzed for concentrations of polychlorinated biphenyls (PCBs), organochlorines (DDT-type compounds and their degradates), polybrominated biphenyl ethers (PBDEs), polycyclic aromatic hydrocarbons (PAHs), waste indicators (WW), and yeast estrogen screen (YES) by the U.S. Geological Survey (USGS) at the Columbia Environmental Research Center (CERC)...
