Contaminant Data from a Survey of Minnesota Source and Finished Drinking Waters, 2019-2022 Contaminant Data from a Survey of Minnesota Source and Finished Drinking Waters, 2019-2022
The U.S. Geological Survey, in cooperation with the Minnesota Department of Health, conducted a study to determine the occurrence of unregulated contaminants in source and finished drinking waters throughout Minnesota. Minnesota relies on both groundwater and surface water sources for drinking water, which may be vulnerable to influences such as wastewater discharge and/or agricultural...
Model outputs and model code for a mining water-use model, 2020, United States excluding territories Model outputs and model code for a mining water-use model, 2020, United States excluding territories
Two machine learning (ML) models (random forest [RF] and light gradient boosting machine [LGB]) were developed to estimate water use for mining for all 50 States for each month of 2020. The two ML models were trained using water use data available from 2019 to 2020 for 30 states along with multiple predictor variables on energy resources, mineral production, and mining employment. The...
Daily reference and potential evapotranspiration, supporting meteorological data from weather stations, solar insolation data from the GOES satellite, and blue-sky albedo data from the MODIS satellite, Florida, 2025 Daily reference and potential evapotranspiration, supporting meteorological data from weather stations, solar insolation data from the GOES satellite, and blue-sky albedo data from the MODIS satellite, Florida, 2025
Potential evapotranspiration (PET) and reference evapotranspiration (ETo) are estimated using the Priestley-Taylor equation and the Penman-Monteith method, respectively (Mecikalski and others, 2018), at an approximately 2-kilometer (approximately 0.019 degrees longitude and 0.018 degrees latitude) spatial grid and daily time-step from January 1, 2025 to December 31, 2025 for the State of...
Putative Polar Bear Locations Detected in Satellite Imagery on the Beaufort Sea Coast of Alaska Putative Polar Bear Locations Detected in Satellite Imagery on the Beaufort Sea Coast of Alaska
This dataset provides the locations of putative polar bears that were visually detected within very high-resolution optical satellite imagery on the Beaufort Sea coast of Alaska. Results are provided as geospatial polygons saved in the shapefile format. These data are based on visual interpretation of very high-resolution optical satellite imagery collected at sites on the Beaufort Sea...
Mercury speciation in surface-waters of South San Francisco Bay, California Mercury speciation in surface-waters of South San Francisco Bay, California
The southern portion of the San Francisco Bay (SFB) Estuary, California, is impacted by mercury (Hg) contamination associated with multiple sources, including: a) inputs from the Guadalupe River watershed, which drains the historic New Almaden Mercury Mining district, b) the entrainment of waters from the northern portion of SFB and the Sacramento-San Joaquin Delta, which are also...
Optical measurements for surface water samples collected within South San Francisco Bay in support of mercury modeling Optical measurements for surface water samples collected within South San Francisco Bay in support of mercury modeling
Little is known about mercury concentrations at bay margins, and how climate change, including changes in temperature and precipitation, will affect mercury exposure and methylmercury (MeHg) production. In addition, the San Francisco South Bay Salt Ponds Restoration Program (SBSPRP) needs more efficient and effective mercury monitoring approaches at larger spatial scales to understand...
Concentrations of per-and polyfluoroalkyl substances (PFAS) in dragonfly larvae and water collected from National Park Service lands, U.S. Fish and Wildlife Service refuges, and Tribal lands across the continental United States, 2021-24 Concentrations of per-and polyfluoroalkyl substances (PFAS) in dragonfly larvae and water collected from National Park Service lands, U.S. Fish and Wildlife Service refuges, and Tribal lands across the continental United States, 2021-24
This data release provides per- and polyfluoroalkyl substances (PFAS) data from dragonfly larvae (various species) and surface water collected on National Park Service lands, U.S Fish and Wildlife refuges, and Tribal lands across the continental United States between 2021-2024.
Topographic data, aerial imagery, and GPS data collected during uncrewed aircraft system (UAS) operations at Assateague Island National Seashore, Berlin, Maryland, 2026 Topographic data, aerial imagery, and GPS data collected during uncrewed aircraft system (UAS) operations at Assateague Island National Seashore, Berlin, Maryland, 2026
The U.S. Geological Survey deployed small uncrewed aircraft systems (sUAS) to collect aerial remote sensing data across two sites within Assateague Island National Seashore (ASIS) where there are planned restoration efforts by the National Park Service (NPS). Natural-color (RGB) aerial imagery and raw lidar data were collected over the course of 3 days in March 2026 during the "leaf-off"...
Data Release for "Cavity-nesting bee nesting success across gradients of floral resources and land-cover' Data Release for "Cavity-nesting bee nesting success across gradients of floral resources and land-cover'
We measured nesting rates and nesting success for a community of cavity-nesting bees across gradients of floral abundance, floral richness, and land-cover in the Prairie Pothole Region. Variables in this dataset include a unique transect identifier, a count of the occupied nests per transect, total floral species richness per transect, total floral stem abundance per transect, bee...
MODFLOW-NWT and MODPATH6 Models Used to Simulate Groundwater Flow in the Regional Aquifer System of Long Island, New York, for Pumping and Recharge Conditions in 2005-2015 (ver. 2.0, December 2021) MODFLOW-NWT and MODPATH6 Models Used to Simulate Groundwater Flow in the Regional Aquifer System of Long Island, New York, for Pumping and Recharge Conditions in 2005-2015 (ver. 2.0, December 2021)
In 2016, the United States Geological Survey (USGS) began development of a regional-scale numerical model of the Long Island aquifer system, as part of the National Water Quality Assessment (NAWQA) Program. The three-dimensional groundwater-flow model was developed to evaluate 1) responses of the hydrologic system to changes in natural and anthropogenic hydraulic stresses 2) the...
