These data sets present results from the analyses of groundwater samples collected from monitoring wells and monitoring intervals in bedrock wells in the mudstone aquifer underlying the former Naval Air Warfare Center (NAWC), West Trenton, NJ. The water samples were collected between 2008 and 2013 and were analyzed for field parameters, inorganic and organic constituents, and the abundances of selected microbes of importance to the evaluation of biological degradation of organic contaminants in groundwater. The collection and analyses of the groundwater samples coincides with conducting a bioaugmentation experiment in a targeted region of the mudstone aquifer. The purpose of the bioaugmentation was to introduce...
This Benthic Invertebrate Community Analysis dataset, a conceptual subgroup of the Lake Erie Ecological Investigations (LEEI) dataset, focuses on the benthic invertebrates sampled at Areas of Concern (AOCs) on Lake Erie. Per the Quality Assurance Project Plan (QAPP), the invertebrate samples were taken from sediments remaining from the sediment analysis. Identification of the invertebrates was completed by the same invertebrate taxonomist for both the 1998-2000 evaluation and 1986-87 historical evaluation (Smith et al. 1994) for increased consistency. Oligochaetes were identified to species if possible, chironomids were identified to genus, as adult specimens are needed for specific identification, and other taxa...

Polychlorinated biphenyl (PCB) concentrations were measured in the lower Ottawa River in 2009 before dredging and after dredging in 2011, 2012, 2013, and 2015. Media collected for analysis included sediment, water, macroinvertebrates, and tetragnathid spiders at 18 stations. At each station 16 surface sediment core samples (top 15 cm) were collected and composited together with a mechanical mixer to achieve a homogeneous composite sample. Mid-depth water column samples were collected using a Van Dorn, Niskin or similar type sampler. Artificial substrate samplers (Hester Dendys) were used to collect aquatic macroinvertebrates. Riparian spiders (family Tetragnathidae) were collected from their webs by gloved hand...

The Permian Basin, straddling New Mexico and Texas, is one of the most productive oil and gas (OG) provinces in the United States. OG production yields large volumes of wastewater that contain elevated concentrations of major ions including salts (also referred to as brines), and trace organic and inorganic constituents. These OG wastewaters pose unknown environmental health risks, particularly in the case of accidental or intentional releases. Releases of OG wastewaters have resulted in water-quality and environmental health effects at sites in West Virginia (Akob, et al., 2016, Orem et al. 2017, Kassotis et al. 2016) and in the Williston Basin region in Montana and North Dakota (Cozzarelli et al. 2017, Cozzarelli...
The Lake Erie Ecological Investigations (LEEI) dataset, housed at the Great Lakes Science Center (GLSC) was developed during a reevaluation of Lake Erie Areas of Concern (AOCs) from 1998-2000. These AOCs were recognized as such by the International Joint Commission (IJC) of the United States and Canada due to their severe water pollution problems. The dataset includes data from both the 1998-2000 reevaluation as well as data from other historical evaluations from the 1980’s to mid-1990’s for comparison where available. Data Description: Rivers and harbors of the Great Lakes have been impacted for decades by heavy industrialization, densely populated areas, and agriculture resulting in contamination, eutrophication,...

This Fish Community Analysis dataset, a conceptual subgroup of the Lake Erie Ecological Investigations (LEEI) dataset, focuses on the fish communities sampled at Areas of Concern (AOCs) on Lake Erie. Per the Quality Assurance Project Plan (QAPP), fish were sampled for identification and measurement of length and weight. Identification of fish were done by the same biologists for both the 1998-2000 data and the 1986-87 historical data (Smith et al. 1994). Any fish difficult to identify were preserved in buffered formalin for later identification. If large numbers of a particular species were collected the first thirty fish were measured and weighed; remaining fish were individually measured and group weighed. All...

This data release contains the FluOil software and the inputs and outputs needed to reproduce the FluOil model findings for a related publication (Li and others, 2022). The FluOil model describes the fate and transport of oil-particle aggregates (OPAs) in inland waterbodies by using particle tracking algorithms to represent the advection, dispersion, deposition, and resuspension of OPAs in turbulent flows. FluOil was applied to analyze the OPA deposition areas along a reach of the Kalamazoo River, Michigan, after the July 26, 2010, oil spill incident. Input to the FluOil model include unsteady one-dimensional hydraulics, generated using the Hydrologic Engineering Center-River Analysis System (HEC-RAS) 5.0.3 model,...
This USGS data release includes all the data presented in peer-reviewed publication entitled "Degradation of MCHM (4-methylcyclohexanemethanol) in Sediments from Elk River, West Virginia". We conducted experiments on crude MCHM to examine photooxidation or biodegradation. We also assessed the potential of sediments to serve as a long-term source of MCHM and well as the potential for native microbial communities to catalyze the anaerobic breakdown of MCHM. We developed a quantitative method to measure the 2 isomers (cis- and trans-) of 4-MCHM, using solid phase micro-extraction (SPME), which had a minimum detection limit of 5 µg/L. The data release shows that the abiotic degradation experiments showed no evidence...
This data set shows the locations of more than 35,000 industrial facilities in North America that reported releases and (or) transfers of pollutants in 2005. The data were assembled from the three North American countries' Pollutant Release and Transfer Registers (PRTRs): the National Pollutant Release Inventory (NPRI) in Canada, the Registro de Emisiones y Transferencias de Contaminantes (RETC) in Mexico, and the Toxics Release Inventory (TRI) in the United States. Additional information on North American pollutant releases and transfers is available through the Commission for Environmental Cooperation's Taking Stock web site at http://www.cec.org/takingstock/.
