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...

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 monitoring has...

MODFLOW-NWT model used to evaluate effects of complexity on head and flow calibration in the Fox-Wolf-Peshtigo watersheds, Wisconsin: U.S. Geological Survey data release.

This data release contains three groundwater-flow models of northeastern Wisconsin,
USA, that were developed with differing levels of complexity to provide a framework for
subsequent evaluations of the effects of process-based model complexity on estimates
of groundwater age distributions for withdrawal wells and streams. Preliminary
assessments, which focused on the...

Datasets for the report entitled: "A Method for Addressing Differences in Concentrations of Fipronil and Three Degradates Obtained by Two Different Laboratory Methods"

This report provides data input and computation results for a method developed by Crawford and Martin (2017) to address differences in concentrations of fipronil and three degradates obtained by two different laboratory methods. Data are arranged in 9 tables that include water-quality site information, laboratory recovery data, laboratory analyses results and measured water-sample concent

Snake River above Jackson Lake at Flagg Ranch, WY (YSNA)

Snake River above Jackson Lake at Flagg Ranch, WY (YSNA) Sample Collection: Samples were collected near the USGS stream gage 13010065 (Latitude 44°05'56", Longitude 110°40'03" NAD83). At the time of collection, all waters samples were filtered through a syringe filter (0.45-micrometer). Two splits of the filtered water were retained for chemical analyse

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

MODFLOW2000_FMP1_1 model used to simulate the groundwater flow of the Central Valley Aquifer, California

A three-dimensional groundwater flow model (MODFLOW200-FMP1_1) of the Central Valley in
California was developed to aid water managers in understanding how water moves through the
aquifer system, to predict water-supply scenarios, and to address issues related to water
competition. The USGS Groundwater Resources Program made a detailed assessment of
groundwater...

MODFLOW-NWT groundwater flow model and GWM-VI optimization code for the Little Plover River Basin in Wisconsin's Central Sand Plain

The Little Plover River groundwater flow model simulates three-dimensional groundwater
movement in and around Wisconsin’s Little Plover River basin under steady-state and
transient conditions. The groundwater flow model uses the U.S. Geological Survey’s
MODFLOW-NWT modeling code. This model explicitly includes all high-capacity
wells in the model domain and simulates...

Agricultural Pesticide Use Estimates for the USGS National Water Quality Network, 1992-2014: Version 2

The National Water Quality Network (NWQN) for Rivers and Streams includes 113 surface-water river and stream sites monitored by the U.S. Geological Survey (USGS) National Water Quality Program (NWQP). The NWQN represents the consolidation of four historical national networks: the USGS National Water-Quality Assessment (NAWQA) Project, the USGS National Stream Quality Accountin

Methane and benzene in drinking-water wells overlying the Eagle Ford, Fayetteville, and Haynesville Shale hydrocarbon production areas

Groundwater samples were collected from domestic and public-supply wells in the Eagle Ford study area in 2015–16, in the Fayetteville study area in 2015, and in the Haynesville study area in 2014–15. One sample of produced water was collected from a gas well in the Haynesville Shale in Rusk County, Texas in 2010, and 5 samples of produced water were collected from oil and
