Predictive modeling reveals elevated conductivity relative to background levels in freshwater tributaries within the Chesapeake Bay watershed, USA

Elevated conductivity (i.e., specific conductance or SC) causes osmotic stress in freshwater aquatic organisms and may increase the toxicity of some contaminants. Indices of benthic macroinvertebrate integrity have declined in urban areas across the Chesapeake Bay watershed (CBW), and more information is needed about whether these declines may be due to elevated conductivity. A predictive SC model

Predictions of groundwater PFAS occurrence at drinking water supply depths in the United States

Per- and polyfluoroalkyl substances (PFAS), known colloquially as “forever chemicals”, have been associated with adverse human health effects and have contaminated drinking water supplies across the United States owing to their long-term and widespread use. People in the United States may unknowingly be drinking water that contains PFAS because of a lack of systematic analysis, particularly in dom

State of science, gap analysis, and prioritization for southeastern United States water-quality impacts from coastal storms—Fiscal year 2023 program report to the Water Resources Mission Area from the Water Availability Impacts of Extreme Events Program—H

Tropical cyclones (coastal storm events that include tropical depressions, tropical storms, and hurricanes) cause landscape-scale disturbances that can lead to impaired water quality and thus reduce water availability for use. Stakeholders and scientists at local and national scales have illustrated a need for understanding these risks to water quality. A regional and comprehensive understanding o

Preliminary Research Sheds Light on Proper Analysis and Sample Handling for the Tire-Derived Contaminants 6PPD and 6PPD-quinone

Tire and road wear particles have been shown to cause acute effects to sensitive aquatic animals and degrade their habitats. U.S. Geological Survey (USGS) scientists developed methods to accurately identify aquatic compounds, such as 6PPD and 6PPD-quinone, that can cause acute mortality events in coho salmon (Oncorhynchus kisutch).

Groundwater Monitoring Program for the Brunswick-Glynn County Area, Georgia

In the Brunswick, Georgia area, saltwater has contaminated the Upper Floridan aquifer for nearly 50 years. Saltwater contamination has constrained further development of the Upper Floridan aquifer in the Brunswick area, which has stimulated interest in the development of alternative sources of water supply, primarily from the shallower surficial and Brunswick aquifer systems. USGS is working...
