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 plac
National Water Dashboard (NWD)
The National Water Dashboard (NWD) is a mobile, interactive tool that provides real-time information on water levels, weather, and flood forecasts - all in one place on a computer, smartphone, or other mobile device. The NWD presents real-time stream, lake and reservoir, precipitation, and groundwater data from more than 13,500 USGS observation stations across the country.
Geophysical and direct groundwater data collected on Palmyra Atoll to study fresh/saline groundwater interfaces from 2008 to 2019
The surface ecology of small ocean islands is directly linked to subsurface fresh water resources, which exist in the form of soil water and fresh groundwater lenses. The management of threaten plant species such as the tree Pisonia grandis needs to consider the spatial and temporal dynamics of groundwater lenses, particularly in a time of climate change. The Palmyra Atoll National Wildlife R...
Data from Decadal Change in Groundwater Quality Web Site, 1988-2018
Evaluating Decadal Changes in Groundwater Quality: Groundwater-quality data were collected from 5,000 wells between 1988-2001 (first decadal sampling event) by the National Water-Quality Assessment Project. Samples are collected in groups of 20-30 wells with similar characteristics called networks. About 1,500 of these wells in 67 networks were sampled again approximately 10 years later
NHD-RC: Extension of NHDPlus Version 2.1 with high-resolution river corridor attributes
This hybrid medium-resolution national hydrography dataset with river corridor attributes (NHD-RC) for the conterminous United States (CONUS) was created by merging lentic and lotic attributes from the high-resolution NHDPlus (U.S. Geological Survey, 2020) into the medium-resolution NHDPlus Version 2.1 (U.S. Geological Survey, 2016). NHD-RC includes attributes from an addition
Mercury and selenium chemical characteristics and speciation data of bird, fish, and earthworm tissues
Birds (Clark’s grebe , Aechmophorus clarkii; Forster’s Tern, Sterna forsteri), fish (Peacock bass, Cichla temensis, Cichla monoculus; Pescada, Plagioscion squamosissimus) and earthworms were analyzed for selenium, total mercury, and methyl mercury c oncentration and mercury speciation. A Clark’s grebe was collected from Lake Berryessa (Califor
Surface geophysical data for characterizing shallow, discontinuous frozen ground near Fort Yukon, Alaska
The distribution of permafrost in cold regions is subject to temporal and spatial changes influenced by climate, landscape disturbance, and ecosystem succession. Remote sensing from airborne and satellite platforms is increasing our understanding of landscape-scale permafrost distribution, but typically lacks the resolution to characterize finer-scale processes and phenomena, which are of
Seepage meter efficiency in highly permeable settings source data (2020)
Efficiency of seepage meters, long considered a fixed property associated with the meter design, is not constant in highly permeable sediments. Instead, results from this study indicate that efficiency varies substantially with seepage-bag fullness, duration of bag attachment, depth of meter insertion into the sediments, and seepage velocity. Efficiency also varies substantially in
Water quality and gas fluxes of streams and lakes in Interior Alaska (ABoVE project)
This product consists of multiple tabular datasets and associated metadata of water quality information related to rivers, streams, and lakes in the Yukon River watershed between 2014 and 2018. This data release is apart of the National Aeronautics and Space Administration (NASA) funded Arctic-Boreal Vulnerability Experiment (ABoVE) and is an assessment of water quality, quantity,
Long-term hydrological and biological data from Williams and Shingobee Lakes, north-central Minnesota
The Shingobee Headwaters Aquatic Ecosystem Project is a long-term, multi-disciplinary monitoring and research study of a 28-square-kilometer headwaters watershed in north-central Minnesota that began in 1978. Emphasis is on processes related to hydrology, limnology, geochemistry, and watershed ecology and the land-water and atmosphere-water interfaces. Lakes are a substantial focus and
A Two-Year Water-Column Time Series of Geochemical Data During a Limnological Shift in Mono Lake, California, 2017-2018
Mono Lake is a hypersaline (~85 ppt), alkaline (pH 9.8), closed-basin lake located in the eastern Sierra Nevada Mountains of California, USA (38°N, 119°W). Water enters the lake primarily from snowmelt and exits by evaporation (~1 m/yr). This hydrological condition, plus weathering reactions in the lake’s tributaries, produce the uniquely high s
Data for food matrix reference materials for hydrogen, carbon, nitrogen, oxygen, and sulfur stable isotope-ratio measurements
An international project developed, quality-tested, and measured isotope−delta values of 10 new food matrix reference materials (RMs) for hydrogen, carbon, nitrogen, oxygen, and sulfur stable isotope-ratio measurements to support food authenticity testing and food provenance verification. These new RMs, USGS82 to USGS91, will enable users to normalize measurements of s
