Prototype updated principal aquifer datasets for three aquifer systems in the Upper Midwest, USA Prototype updated principal aquifer datasets for three aquifer systems in the Upper Midwest, USA
This geospatial dataset represents a prototype of a finer-scale representation of the principal aquifers of the United States, using four original principal aquifers in the Upper Midwest, United States, which were re-analyzed and condensed into three updated principal aquifers. The original principal aquifer definitions and extents were published in the Ground Water Atlas of the United...
KdPAR and surface water-quality data collected in the Sacramento-San Joaquin River Delta in 2013 and 2014 KdPAR and surface water-quality data collected in the Sacramento-San Joaquin River Delta in 2013 and 2014
Data release provides diffuse light attenuation coefficient of photosynthetically active radiation (KdPAR) derived from in-situ light measurements, along with surface water-quality and atmospheric data collected in the Sacramento-San Joaquin Rive Delta in California between January 2013 and May 2014. These associated surface level water-quality and atmospheric data, and categorical...
Laboratory fluorescence and total dissolved nitrogen measurements for surface water samples collected from the Rio Grande during a 24-hr time period near Albuquerque, New Mexico Laboratory fluorescence and total dissolved nitrogen measurements for surface water samples collected from the Rio Grande during a 24-hr time period near Albuquerque, New Mexico
Here, we present data supporting temporal variability and sources of PFAS in the Rio Grande through an arid urban area using high-frequency sampling and novel samplers. Data are compiled into two tables: 1) full fluorescence spectra in vectorized format, and 2) summary file of concentrations of total dissolved nitrogen and commonly extracted field-based sensor arrays. Data are reported...
Macroinvertebrate communities in Shenandoah Valley streams, 2021 Macroinvertebrate communities in Shenandoah Valley streams, 2021
From 20 May - 8 June 2021, a Virginia Tech team of 2-3 sampled the macroinvertebrate community in 30 Shenandoah Valley streams (Virginia and West Virginia, USA) as part of a larger stream-health study including other teams who surveyed geomorphology, water quality, flow, temperature,fish community, and fish health at the same 30 streams. The macroinvertebrate community team also...
Metrics of Resilience in Water Management Institutions in the Upper Colorado and Delaware River Basins, United States 2022 Metrics of Resilience in Water Management Institutions in the Upper Colorado and Delaware River Basins, United States 2022
The data in this data release are from an effort focused on understanding social vulnerability to water insecurity, resiliency demonstrated by institutions, and conflict or crisis around water resource management. This data release focuses on definitions and metrics of resilience in water management institutions. Water resource managers, at various scales, are tasked with making complex...
Microcosm experiment data of microcystin-degrading bacteria in Lake Erie source waters and drinking-water plants, 2015-18 Microcosm experiment data of microcystin-degrading bacteria in Lake Erie source waters and drinking-water plants, 2015-18
In 2015-2018, the U.S. Geological Survey (USGS) in cooperation with the U.S. Environmental Protection Agency Great Lakes Restoration Initiative investigated the biodegradation of microcystins in source waters and sand filters from drinking-water plants in the Western Lake Erie Basin. Four source waters and three sand filtrate samples were collected from the intakes and sand filters of...
