Surface-water-quality data to support implementation of revised freshwater aluminum water-quality criteria in Massachusetts, 2018–19

The U.S. Geological Survey, in cooperation with the Massachusetts Department of Environmental Protection, performed a study to inform the development of the department’s guidelines for the collection and use of water-chemistry data to support calculation of site-dependent aluminum criteria values. The U.S. Geological Survey collected and analyzed discrete water-quality samples at four wastewater-t

Arsenic in private well water and birth outcomes in the United States

BackgroundPrenatal exposure to drinking water with arsenic concentrations >50 μg/L is associated with adverse birth outcomes, with inconclusive evidence for concentrations ≤50 μg/L. In a collaborative effort by public health experts, hydrologists, and geologists, we used published machine learning model estimates to characterize arsenic concentrations in private wells—federally unregulated for dri

Research on Per- and Polyfluoroalkyl Substances (PFAS) in the New England Water Science Center

Per- and polyfluoroalkyl substances (PFAS) are a diverse group of over 4,000 different compounds. Since the 1940s, PFAS have been manufactured and used around the globe, including in the United States. PFAS are resistant to chemical and thermal breakdown and impart stain and water-resistance properties, making them useful for a variety of commercial applications, but also persistent in the...

Environmental streamflows in the United States: historical patterns and predictions

The term environmental streamflows refers to the magnitude, frequency, seasonal timing, duration, and rate of change of streamflows needed to sustain freshwater and estuary ecosystems and human wellbeing. It is important that environmental streamflow assessments by water managers consider changes in climate, land use, and water management; this cannot be done effectively without understanding...
