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...

Geohydrology of Fractured Crystalline Rock of Northern Georgia
Groundwater development and use in the fractured crystalline rocks of northern Georgia are critical to sustain population growth and economic development. Knowledge about ground-water movement, storage, vulnerability, quality, and connection with surface-water resources is limited because of the complexity of fractured-rock aquifers that underlie the region. A better understanding of the relation...
Tybee Island Saltwater Intrusion Monitoring
Recent investigations (Ransom and Park, 2011) have indicated that seawater is migrating downward from the ocean floor, through the "Miocene" confining unit, and is nearing the top of the Upper Floridan aquifer, the principal source of fresh drinking water in the Savannah-Tybee Island area. Monitoring ground-water levels and quality is important for protection and effective management of the water...
Brunswick Area Saltwater Intrusion Monitoring
The Upper Floridan aquifer is contaminated with saltwater in a 2-square-mile area of downtown Brunswick, Georgia. The presence of this saltwater has limited the development of the groundwater supply in the Glynn County area. Hydrologic, geologic, and water-quality data are needed to effectively manage water resources.
