Simulation of groundwater flow to evaluate hydrogeologic controls on a PFAS plume, Coakley Landfill Superfund site, Rockingham County, New Hampshire Simulation of groundwater flow to evaluate hydrogeologic controls on a PFAS plume, Coakley Landfill Superfund site, Rockingham County, New Hampshire
Per- and polyfluoroalkyl substances (PFAS), including perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS), have been detected at combined concentrations above 2,000 nanograms per liter (ng/L) at groundwater seep locations near the Coakley Landfill Superfund site, in North Hampton, New Hampshire. The landfill was active from 1972 to 1985. An impermeable cap was placed on...
An automated geographic information system-based hydraulic modeling tool for developing preliminary culvert designs for stream crossings in Massachusetts An automated geographic information system-based hydraulic modeling tool for developing preliminary culvert designs for stream crossings in Massachusetts
Introduction Currently (2026), many of the about 25,000 roadway crossing structures over rivers and streams in Massachusetts are undersized. Undersized culverts and bridges can be detrimental to fish and wildlife movement, habitat continuity, and the health of aquatic organisms. Undersized culverts also can lack the resiliency needed to withstand large floods, which could be worsened by...

Thermal Imaging to Detect Cold-Water Habitat for Atlantic Salmon and Brook Trout at Katahdin Woods and Waters National Monument
The U.S. Geological Survey (USGS), in cooperation with the National Park Service (NPS), is using airborne thermal infrared remote sensing to characterize cold-water habitat for the federally designated endangered species Atlantic salmon ( Salmo salar) and wild brook trout ( Salvelinus fontinalis) in the East Branch of the Penobscot River system within Katahdin Woods and Waters National Monument...
Statewide Studies of PFAS in Connecticut
The U.S. Geological Survey (USGS) New England Water Science Center, in cooperation with the Connecticut Department of Economic and Community Development (CT DECD) and the Connecticut Department of Energy and Environmental Protection (CT DEEP), is investigating the occurrence of per- and polyfluoroalkyl substances (PFAS) in soils and shallow groundwater across the state of Connecticut. The studies...
Coastal Water-Quality Monitoring in Massachusetts
The U.S. Geological Survey (USGS) operates high‑resolution, continuous water‑quality monitoring stations in estuaries across coastal Massachusetts to better understand these dynamic ecosystems. These efforts include collaborations with the Massachusetts Bays National Estuary Partnership (MassBays) and the Massachusetts Department of Environmental Protection (MassDEP) to support Clean Water Act...
