Tapwater exposures, residential risk, and mitigation in a PFAS-impacted-groundwater community Tapwater exposures, residential risk, and mitigation in a PFAS-impacted-groundwater community
Tapwater (TW) safety and sustainability are priorities in the United States. Per/polyfluoroalkyl substance(s) (PFAS) contamination is a growing public-health concern due to prolific use, widespread TW exposures, and mounting human-health concerns. Historically-rural, actively-urbanizing communities that rely on surficial-aquifer private wells incur elevated risks of unrecognized TW...
Statewide cumulative human health risk assessment of inorganics-contaminated groundwater wells, Montana, USA Statewide cumulative human health risk assessment of inorganics-contaminated groundwater wells, Montana, USA
Across the United States, rural residents rely on unregulated and generally unmonitored private wells for drinking water, which may pose serious health risks due to unrecognized contaminants. We assessed the nature, degree, and spatial distribution of cumulative health risks from inorganic contaminants in groundwater. Our analysis included nearly 84,000 data points from 6500+ wells...
Ecohydrological response of a forested headwater catchment to a flash drought in the Southeastern U.S. Ecohydrological response of a forested headwater catchment to a flash drought in the Southeastern U.S.
Flash droughts differ from traditionally defined droughts in their rapidity of intensification and often associated high vapor-pressure deficit. These droughts can lead to declines in streamflow and water table depth and induce water stress to vegetation at a greater rate than droughts that manifest over longer periods. However, little is known regarding the response of forested...

Hydrogeologic Assessment and Simulation of Stream-Aquifer Relations in the Lower Apalachicola-Chattahoochee-Flint River Basin
Current hydrologic information and groundwater-flow modeling in the lower Apalachicola - Chattahoochee - Flint (ACF) River Basin (inset map) are insufficient to describe effects of time-variant irrigation pumping on streamflow. Therefore, existing models cannot accurately predict ground-water or streamflow conditions during a growing season. The Georgia Department of Natural Resources...
Archived and Completed Projects - South Atlantic Water Science Center
The USGS South Atlantic Water Science Center (SAWSC) is comprised of water-science offices throughout Georgia, North Carolina, and South Carolina. The SAWSC conducts research and investigations related to topics such as groundwater and surface-water quality related to anthropogenic and agricultural activities, hydraulic and hydrologic modeling, tracking the movement of groundwater contamination...
Lake Seminole Hydrologic Analysis - USGS
Water management in the lower Apalachicola-Chattahoochee-Flint (ACF) River Basin has long concerned Alabama, Florida, and Georgia due to competing freshwater demands. Numerous studies have explored the complex relationships among hydrologic components and natural and human-induced stresses. However, prior research lacked mechanisms to collect real-time data critical for developing a precise water...
