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...

Streamflow characterization and effects of Interstate 26 highway construction on water-quality and channel morphology conditions of the French Broad River in Buncombe and Henderson Counties, North Carolina, 2019–22 Streamflow characterization and effects of Interstate 26 highway construction on water-quality and channel morphology conditions of the French Broad River in Buncombe and Henderson Counties, North Carolina, 2019–22
The North Carolina Department of Transportation began a series of highway construction projects to upgrade Interstate 26 (I–26) in Buncombe and Henderson Counties, North Carolina, starting in early 2020. The North Carolina Department of Transportation and the U.S. Geological Survey partnered in 2019 to monitor and assess water-quality and geomorphic conditions throughout the French Broad...

Assessing streams in the Chesapeake Bay Watershed to guide conservation and restoration activities Assessing streams in the Chesapeake Bay Watershed to guide conservation and restoration activities
Freshwater streams in the Chesapeake Bay watershed are home to numerous aquatic organisms (like fish, amphibians, mussels, and insects) and provide drinking water and recreational opportunities to people living in or visiting the watershed. Land-use changes, such as urban development and increased activities in certain agricultural sectors, have degraded water quality and altered...

Simulation of groundwater flow in Wake County, North Carolina, 2000 through 2070 Simulation of groundwater flow in Wake County, North Carolina, 2000 through 2070
In 2019, the U.S. Geological Survey and Wake County Environmental Services began a collaborative study to evaluate groundwater resources and long-term groundwater availability in the county’s fractured-rock groundwater system. Wake County, in central North Carolina, is experiencing rapid population growth, associated land development, and changing water use. Hydrogeologic data including

Tapwater-contaminant mixtures and risk in a biofuel-facility impacted private-well community Tapwater-contaminant mixtures and risk in a biofuel-facility impacted private-well community
We assessed private-well drinking water (DW) at the point of use (i.e., tapwater, TW) within a rural Nebraska community around a state-closed biofuel facility, which used pesticide-treated corn seed as feedstock for ethanol production. Organic (485), inorganic (34), and microbial (13) analytes were assessed at 15 locations in June 2022, to evaluate the relative contribution of facility...

Regional high-frequency monitoring revealed chloride concentrations in exceedance of ecological benchmarks in urban streams across the Delaware River Basin, USA Regional high-frequency monitoring revealed chloride concentrations in exceedance of ecological benchmarks in urban streams across the Delaware River Basin, USA
Rising chloride concentrations pose critical risks to freshwater stream ecosystems in temperate regions like the Delaware River Basin (DRB), USA, where winter deicer applications (i.e., road salt) are common. Increasing chloride concentrations have been documented in the region, but the extent to which chloride exceeds regulatory benchmarks remains unclear because detection of...

Salting behaviors influence urban stream conductivity in Boston, Massachusetts (USA) Salting behaviors influence urban stream conductivity in Boston, Massachusetts (USA)
Freshwater salinization is a major concern in temperate climates where road salt is used as a deicer to manage snow and ice on roadways. In urban and suburban areas, wastewater, weathering of infrastructure, and salting on parking lots and sidewalks can also contribute to salt contamination, but little is known about how well these sources explain variation in stream conductivity and...

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...
