Data

These metadata sets present the comprehensive geochemical composition of solid and water samples from the site of a 11.4ML (million liters) wastewater spill discovered in January, 2015. Analyses of a pipeline sample (analyses of select analytes), supplied by the North Dakota Department of Health are also included. The spill was near Blacktail Creek, north of Williston, ND. The leak was from a pipe

This data release compiles the whole-rock geochemistry, X-ray diffraction, and electron microscopy analyses of samples collected from the uranium ore bodies of two mined-out deposits in the Grand Canyon region of northwestern Arizona - the Hack II and Pigeon deposits. The samples are grab samples of ore collected underground at each mine by the U.S. Geological Survey (USGS) during the mid-1980s, w

This data package contains the final combined field sampling data collected by the USGS July 2013 and July-August 2015 at three active uranium mines (Canyon Rim Mine, Pinenut Mine, and Arizona 1 Mine) as well as two reference sites (Little Robinson Tank and EZ2 Pipe) in northwestern Arizona. Vegetation and soils were assessed by using line-point intersect (LPI) methods and estimates of plant speci

This dataset characterizes the acute toxicity of copper and zinc to white sturgeon (~30 days post hatch) and cladocerans (

This dataset contains pesticide and pharmaceutical results (including maximum and median summaries) collected in the Southeast Region of the United States, 2015-17. Water-quality and bed-sediment results are reported. Samples were analyzed at the National Water Quality Laboratory, Denver, Colorado and the Organic Chemistry Research Laboratory, Sacramento, California. Method and site information is

This data release presents chemical and biological results from investigations of water quality, fish endocrine disruption, and emergent insects in the Shenandoah River Watershed (Virginia and West Virginia, USA) conducted during 2014, 2015, and 2016. Multiple sampling campaigns were conducted at sites located throughout the Shenandoah River Watershed (Table 1). The complex inorganic and organic c

These analyses provide the basic geochemical composition of urban stormwater runoff from rainwater/stormwater that does or has the potential to infiltrate groundwater from Green Infrastructure control measures. These measures are able to mimic the natural landscape with engineered designed systems to enhance stormwater infiltration to groundwater.

The U.S. Geological Survey is studying the interaction of a contaminated groundwater plume enriched in uranium and other trace elements with water, sediment, and biota along a 3 km reach of the Little Wind River in central Wyoming. The source of the contaminants is from a reclaimed uranium mill site near Riverton, Wyoming. The study is being done in collaboration with the Department of Energy, Uni

Data from study assessing the utility of knowledgebase-leveraging of comprehensive environmental-contaminant-exposure datasets by comparing biological effects predicted on the basis of target chemical analyses with measured biological effects in corresponding split water samples.

This data set contains the result for inorganic constituents and organic compounds collected from tapwater locations, as well as water filtration plants, in East Chicago, Indiana, and Chicago, Illinois in 2017. Additionally quality assurance data collected was summarized. Residential samples collected were done so directly from residential kitchen taps (faucets) as is, it was noted if a point-of-u

Water, bed sediment, and biota were sampled in streams from Butte to near Missoula, Montana, as part of a monitoring program in the upper Clark Fork Basin of western Montana. The sampling program was led by the U.S. Geological Survey (USGS), in cooperation with the U.S. Environmental Protection Agency.

These data sets present results from the analyses of chlorinated ethene compounds in samples of rock core collected from boreholes in the mudstone underlying the former Naval Air Warfare Center, West Trenton, New Jersey.
