Geochemical, mineralogical, and grain-size data for in-situ solid materials and suspended sediment at Malakoff Diggins State Historic Park, Nevada County, California Geochemical, mineralogical, and grain-size data for in-situ solid materials and suspended sediment at Malakoff Diggins State Historic Park, Nevada County, California
This dataset includes data for in-situ solid materials and suspended sediments from surface-water samples, as well as surface-water chemistry from samples collected during storm events at Malakoff Diggins State Historic Park, Nevada County, California. In-situ solid samples were collected during 2015 along six vertical transects along the cliff walls of the mine pit. Surface-water...
Specific conductance and water chemistry data for selected rivers and creeks in Yellowstone National Park, beginning in 2010 (ver. 3.0, November 2025) Specific conductance and water chemistry data for selected rivers and creeks in Yellowstone National Park, beginning in 2010 (ver. 3.0, November 2025)
Measuring the thermal output of Yellowstone’s large magmatic system is not straightforward, as there are thousands of thermal features spread across 3470 square miles. One way to capture and integrate the thermal discharge from this broad area is to monitor river chemistry, because thermal water discharge eventually enters a nearby river, which acts as a collection and delivery system...
Water chemistry data for selected hot springs and rivers in Southwest Yellowstone National Park, Wyoming Water chemistry data for selected hot springs and rivers in Southwest Yellowstone National Park, Wyoming
Water analyses are reported for 66 samples collected from numerous thermal and non-thermal (rivers and streams) features in the southwestern areas of Yellowstone National Park (YNP) during 2009, 2017, and 2018. Water samples were collected from sources near Boundary Creek, Bechler River, Falls River, Mountain Ash Creek, Upper Snake River, Spirea Creek, and Lewis Lake. These water samples...
Assessment of Endocrine Disruption in the Shenandoah River Watershed - Chemical and Biological Data from Mobile Laboratory Fish Exposures and Other Experiments Conducted during 2014, 2015, and 2016 Assessment of Endocrine Disruption in the Shenandoah River Watershed - Chemical and Biological Data from Mobile Laboratory Fish Exposures and Other Experiments Conducted during 2014, 2015, and 2016
This data release presents chemical and biological results from investigations of water quality, fish endocrine disruption, and emergent insects in the Shenandoah River Watershed (Virginia and West Virginia, USA) conducted during 2014, 2015, and 2016. Multiple sampling campaigns were conducted at sites located throughout the Shenandoah River Watershed (Table 1). The complex inorganic and...
Survey of major and trace elements in stormwater runoff from across the United States, 2016 to 2017 Survey of major and trace elements in stormwater runoff from across the United States, 2016 to 2017
This study focuses on providing a broad-scale assessment of composition of water chemistry in urban stormwater runoff. The stormwater runoff is a source of recharge to groundwater by Green Infrastructure (GI) practices or it may become a source of recharge to groundwater to reduce stormwater volumes to surface waters or augment groundwater supply. The chemical composition of the...
Major, trace, and rare earth element concentration measured in water samples collected during the September 2013 Colorado South Platte River flood Major, trace, and rare earth element concentration measured in water samples collected during the September 2013 Colorado South Platte River flood
Major flood events have the potential to impact water quality. In this study, the effects of the September 2013 South Platte River flood in Colorado were assessed on the urban water cycle and basin-wide scales using time-series water sampling of three source waters (tap water, wastewater treatment facility effluent, and receiving stream) and a longitudinal sampling of the South Platte...
