Streamflow, water quality, and constituent loads and yields, Scituate Reservoir drainage area, Rhode Island, water year 2023 Streamflow, water quality, and constituent loads and yields, Scituate Reservoir drainage area, Rhode Island, water year 2023
As part of a long-term cooperative program to monitor water quality within the Scituate Reservoir drainage area, the U.S. Geological Survey, in cooperation with Providence Water (formerly the Providence Water Supply Board), collected streamflow and water-quality data in tributaries to the Scituate Reservoir, Rhode Island. Streamflow and concentrations of chloride and sodium estimated...
An automatable method for developing preliminary stream crossing designs using lidar and hydraulic modeling in Massachusetts An automatable method for developing preliminary stream crossing designs using lidar and hydraulic modeling in Massachusetts
Upgrading aging and undersized stream crossings (places where culverts and bridges intersect a stream) with replacements designed for aquatic organism passage can improve infrastructure resiliency, geomorphic stability, and maintenance costs. The goal of this work is to develop preliminary culvert designs that convey hydraulic design floods and meet the Massachusetts Stream Crossings...
Predictions of anthropogenic background PFAS concentrations in soil and relation to bedrock lithology and groundwater quality Predictions of anthropogenic background PFAS concentrations in soil and relation to bedrock lithology and groundwater quality
Detectable concentrations of per- and polyfluoroalkyl substances (PFAS) have been observed in soils in remote areas and presumably originate from atmospheric deposition. These anthropogenic background concentrations may enable some PFAS to leach to groundwater at levels that exceed regulatory criteria for drinking water. However, anthropogenic background soil concentrations and their...

Not All PFAS Are Alike: Fish Responses Reveal The Importance Of Real-World Mixtures
A USGS study demonstrates the importance of monitoring not just the amount of PFAS in groundwater, but the PFAS mixture present. Building on two decades of experience conducting mobile laboratory experiments, USGS researchers applied this approach at a contaminated fire training area to evaluate how fish respond to complex PFAS mixtures, providing important scientific evidence that can improve how...
Developing Riverine and Pluvial Flood Hazard Tools for Planning and Mitigation in Massachusetts
The U.S. Geological Survey (USGS), in cooperation with the Massachusetts Executive Office of Energy and Environmental Affairs (EOEEA), is developing a web-based tool to visualize flood data in Massachusetts. Climate projections, including those derived from the Climate and Hydrologic Risk Project, are being incorporated into new and existing flood models in pilot areas distributed across the...
Assessing Sustainable Water Use in Connecticut
The U.S. Geological Survey (USGS) New England Water Science Center, in cooperation with the Connecticut Department of Energy and Environmental Protection (CT DEEP), is updating a planning-level support tool to help decision makers estimate daily mean streamflows and selected streamflow statistics to assess sustainable water use across the state of Connecticut.
