Data for Radium Mobility and the Age of Groundwater in Public-drinking-water Supplies from the Cambrian-Ordovician Aquifer System, North-Central USA

High radium (Ra) concentrations in potable portions of the Cambrian-Ordovician (C-O) aquifer system were investigated using water-quality data and environmental tracers ( 3H, 3Hetrit, SF6 , 14C and 4Herad) of groundwater age from 80 public-supply wells (PSWs). Groundwater ages were estimated by calibration of tracers to lumped parameter models and ranged from modern (1 Myr

GSFLOW model of the upper Deschutes Basin, Oregon

A three-dimensional integrated groundwater/surface-water model was developed for the upper
Deschutes Basin in central Oregon to better understand groundwater and surface-water flow
and interconnections, and to provide the capability for simulating the hydrologic response to
external stresses including climate change. The model was calibrated using groundwater and

Water-quality and streamflow datasets used in Seasonal Kendall trend tests for the Nation’s rivers and streams, 1972-2012 (output)

In 1991, the U.S. Geological Survey (USGS) began a study of more than 50 major river basins across the Nation as part of the National Water-Quality Assessment (NAWQA) project of the National Water-Quality Program. One of the major goals of the NAWQA project is to determine how water-quality conditions change over time. To support that goal, long-term consistent and comparable monitor

MCHM Degradation Data Release

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 na

Field spectra from rivers in Alaska, September 19-21, 2016

The U.S. Geological Survey collected field spectra collected from three rivers in Alaska September 19-21, 2016, to support research on remote sensing of river discharge. Reflectance measurements were made from bridges across the Chena River, Salcha River, and Montana Creek using an Analytical Spectral Devices FieldSpec3 spectroradiometer operated in reflectance mode. The original *.as

ADCP data from rivers in Alaska, September 18-20, 2016

The U.S. Geological Survey obtained measurements of channel geometry, flow velocity, and river discharge from five rivers in Alaska September 18-20, 2016, to support research on remote sensing of river discharge. The streamflow data were acquired from the Knik, Matanuska, Chena, and Salcha Rivers and Montana Creek using TeleDyne RD Acoustic Doppler Current Profilers (ADCPs),

Transient Electromagnetic Surveys Collected for Delineation of Saline Groundwater in the Genesee Valley, New York, October-November 2016

In late October and early November 2016, transient electromagnetic (TEM) data were acquired at two locations in Livingston County, in western New York, in order to characterize the subsurface resistivity structure in support of a U.S. Geological Survey groundwater investigation. The TEM data were collected as part of a pilot project to evaluate geophysical methods to characterize the

MODFLOW-2005 data sets for simulation of Groundwater-Flow Budget for the Lower Apalachicola-Chattahoochee-Flint River Basin in Southwestern Georgia and Parts of Florida and Alabama, 2008-12

As part of the National Water Census program in the Apalachicola-Chattahoochee-Flint (ACF)
River Basin, the U.S. Geological Survey evaluated the groundwater budget of the lower ACF,
with particular emphasis on recharge, characterizing the spatial and temporal relation between
surface water and groundwater, and groundwater pumping. To evaluate the hydrologic budget of

Isotopic and chemical composition (δ13C, Δ14C, δ15N, C:N, SUVA254nm, % HPOA) of aquatic carbon and field conditions (water temperature, pH, discharge) in the Upper Mississippi River Basin, October 2014 – February 2016

This dataset contains stable isotope (δ13C) and radioisotope (Δ14C) compositions of dissolved inorganic carbon, dissolved organic carbon, particulate organic carbon, and bed material organic carbon samples collected from rivers in the Upper Mississippi River Basin between October 2014 and February 2016. Rivers were sampled at USGS gaging stations: Minnesota River at Fort
