Till geochemistry from rotosonic cores in Minnesota, USA

Samples for analysis were selected from 1) archived rotosonic cores drilled by the Minnesota Geological Survey and archived at the Lands and Minerals Drill Core Library, Minnesota Department of Natural Resources, Hibbing, Minnesota, USA; or b) freshly collected rotosonic cores, collected on-site at the time of coring. Cores in the sample archive are stored in wooden core-boxes in ambient air. Core

Geophysical Data Collected for an Assessment of a Proposed Landfill Site in Fredericktown, Missouri, June 2018

In June 2018, the U.S. Geological Survey (USGS) in cooperation with the U.S. Environmental Protection Agency (EPA) collected geophysical measurements to help evaluate the suitability of a proposed landfill site for disposing mine-waste materials in Fredericktown, Missouri. Geophysical methods were used to evaluate and characterize the unconsolidated sediment (i.e., regolith) above the crystalline

Datasets of Groundwater-Quality and Select Quality-Control Data from the National Water-Quality Assessment Project, January 2017 through December 2019

Groundwater-quality data were collected from 983 wells as part of the National Water-Quality Assessment Project of the U.S. Geological Survey National Water-Quality Program and are included in this report. The data were collected from six types of well networks: principal aquifer study networks, which are used to assess the quality of groundwater used for public water supply; land-use study networ

Surface Water and Porewater Chemistry of Cell 3A, Prado Wetlands, Riverside, CA, USA (2018)

The data presented here was collected at Prado Wetlands in Riverside County, CA, USA. Physical water column parameters were collected using a multprobe sonde and includes date and time of sample collection, location (inlet, outlet), temperature (degrees Celsius), pH, specific conductivity (mircoSiemens per centimeter), and dissolved oxygen (milligrams per liter). An ISCO autosampler was utilized t

MODFLOW-2005 models used to simulate effects of pumping in the Death Valley Regional Groundwater Flow System, Nevada and California—Selected management scenarios projected to 2120

A three-dimensional, groundwater-flow model developed by Halford and Jackson (https://doi.org/10.3133/pp1863) was used to simulate effects of future (2020—2120) groundwater pumping on water levels and natural discharges in the Alkali Flat–Furnace Creek Ranch (AFFCR), Ash Meadows, Pahute Mesa–Oasis Valley (PMOV), and Pahrump to Death Valley South (PDVS) groundwater basins, southern Nevada and Calif

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 between 20

Soil-Water Balance model for alluvial deposits in Summerset, South Dakota

A Soil-Water Balance (SWB) model of the alluvial aquifer in north Summerset, South Dakota, was constructed to estimate recharge and potential evapotranspiration volumes and rates for 2017-19. The model area included the northern part of the city of Summerset in west South Dakota along the east range of the Black Hills. The model area was defined as a rectangular area that included the watershed bo

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 integrator

Turbidity data collected by five in situ sensors at USGS site 02492620 Pearl River at NSTL station, MS from November 2017 to January 2018

Five commercially available turbidity sensors were field tested by the U.S. Geological Survey (USGS) Hydrologic Instrumentation Facility for accuracy and data comparability. The tested sensors were the Xylem EXO (EXO), the Hach Solitax sc (Solitax), the In-Situ Aqua TROLL sensor installed onto a TROLL 600 sonde (TROLL 600), the Campbell Scientific OBS501 (OBS501), and the Observator ANALITE NEP-50
