Datasets of Groundwater-Quality and Select Quality-Control Data from the National Water-Quality Assessment Project, January 2017 through December 2019 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...
Supporting Data for Estimating Selected Low-Flow Frequency Statistics and Mean Annual Flow for Ungaged Locations on Streams in Alabama (ver. 1.1, November 2020) Supporting Data for Estimating Selected Low-Flow Frequency Statistics and Mean Annual Flow for Ungaged Locations on Streams in Alabama (ver. 1.1, November 2020)
Streamflow data and statistics are vitally important for proper protection and management of both the water quality and water quantity of Alabama streams. Such data and statistics are available at U.S. Geological Survey streamflow-gaging stations, also referred to as streamgages or stations, but are often needed at ungaged stream locations. To address this need, the U.S. Geological...
Use of dye-tracing to delineate the recharge area of Manitou Cave, Alabama, towards assessing sensitive stygobiont habitat Use of dye-tracing to delineate the recharge area of Manitou Cave, Alabama, towards assessing sensitive stygobiont habitat
In 2019, dye tracing investigations were conducted near Manitou Cave in Dekalb County, northeast Alabama. The purpose of the dye tracing was to delineate a recharge area for the stream in Manitou Cave, a 1.7-kilometer-long stream cave and the only known habitat for the Manitou Cavesnail (Antroribus breweri). In 2010, the U.S. Fish and Wildlife Service was petitioned by the Center for...
Surface Water and Porewater Chemistry and Nitrogen Biogeochemistry of Cell 3A, Prado Wetlands, Riverside, CA, USA (2018) (ver. 2.0, April 2025) Surface Water and Porewater Chemistry and Nitrogen Biogeochemistry of Cell 3A, Prado Wetlands, Riverside, CA, USA (2018) (ver. 2.0, April 2025)
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...
Data on Flea Parasitism and Annual Re-encounters of Utah Prairie Dogs at 5 colonies on the Awapa Plateau, Utah, USA, 2013-2016 Data on Flea Parasitism and Annual Re-encounters of Utah Prairie Dogs at 5 colonies on the Awapa Plateau, Utah, USA, 2013-2016
Data on flea parasitism and annual re-encounters of Utah prairie dogs at 5 colonies on the Awapa Plateau, Utah, USA, June-August 2013-2016. Utah prairie dogs were live-trapped and sampled on 5 colonies along an elevation gradient from 2,645 m to 2,873 m. Upon first capture each year, we anesthetized each prairie dog and fleas on its body and combed the prairie dog as thoroughly as...
