Tapwater contaminant mixtures and cumulative risk screening on the Crow (Apsáalooke) Reservation Tapwater contaminant mixtures and cumulative risk screening on the Crow (Apsáalooke) Reservation
Introduction: Water insecurity is a challenge for the Apsáalooke (Crow) Tribal Nation in south-central Montana, United States. Both private-well and public-supply tapwater (TW) are vulnerable to a range of contaminants, posing potential risks to community health and well-being. Ongoing community concerns about unrecognized inorganic, organic, and microbial contaminants underscore the...
Remote detection of streambank erosion and channel incision using high-resolution, repeat lidar-derived metrics in Raleigh, North Carolina Remote detection of streambank erosion and channel incision using high-resolution, repeat lidar-derived metrics in Raleigh, North Carolina
This study evaluated the use of lidar data to detect streambank erosion and channel incision throughout Raleigh, North Carolina. The study included five components. (1) Generation of lidar-derived rasters, including a digital elevation model of difference that represented channel erosion and positive openness rasters that represented channel incision. (2) Completion of site-based field...
Comparative screening of private, public, and bottled drinking water in vitro bioactivity Comparative screening of private, public, and bottled drinking water in vitro bioactivity
This study compares in vitro bioactivity profiles of extracts from private tapwater (51 samples), public tapwater (143 samples), and bottled water (31 samples), using high-throughput, multiplex, transcription factor screening. Of 48 biological end points tested, 25 showed significant (≥50% above the field blank) activity. Frequently detected (≥10% of samples) bioactivities (in decreasing...

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...
Raleigh Bank Erosion Project
The City of Raleigh partnered with the U.S. Geological Survey (USGS) to assist in assessing streambank erosion hotspots along the City of Raleigh’s stream network to support the City’s efforts of prioritizing future stream mitigation projects. Streambank erosion potential will be assessed using remotely sensed light detection and ranging (lidar) data, field assessments of streambank conditions...
South Atlantic Water Science Center Drought Monitoring
When rainfall is less than normal for several weeks, months, or years, the flow of streams and rivers declines, water levels in lakes and reservoirs fall, and the depth to water in wells increases. If dry weather persists and water-supply problems develop, the dry period can become a drought.
