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...
Low streamflows in Massachusetts: Variability over space and time and relations with climatic and basin variables Low streamflows in Massachusetts: Variability over space and time and relations with climatic and basin variables
Streamflows in Massachusetts have set record lows in recent years despite generally wetter conditions than during the drought of the 1960s, and the reasons for this are not known. To analyse potential drivers of low streamflows in Massachusetts, six low-flow metrics were computed at 107 streamgages. These metrics represent low-flow magnitude, magnitude normalized to median flows, and...
Groundwater drought in the United States: Spatial and temporal variability Groundwater drought in the United States: Spatial and temporal variability
Many communities and ecosystems in the United States that are dependent on groundwater are potentially adversely affected by groundwater drought. We computed yearly groundwater-drought metrics and mean groundwater levels at well locations across the conterminous United States (CONUS), using data from wells and remotely sensed and modeled Gravity Recovery and Climate Experiment Drought...

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...
Determining How New England’s Water Resources Respond to Various Climate Scenarios
Possible changes in temperature and precipitation over the next several decades may have implications for New England’s agricultural community, such as changing plant water availability and crop yield variability. The U.S. Geological Survey, in cooperation with the U.S. Department of Agriculture and the University of Maine, is predicting the potential hydrological effects based on these climatic...
Thermal Imagery to Inform Brook Trout Habitat Suitability and Restoration Potential, Upper Namekagon River, Wisconsin
The U.S. Geological Survey (USGS), in cooperation with the National Park Service (NPS), is using thermal infrared technology to identify cold-water habitat for brook trout and other cold-water species in the upper Namekagon River in Wisconsin. The upper Namekagon River and its tributaries have long served as a stronghold for brook trout and other cold- and cool-water species; however, changing...
