Data for an Erosion Potential and Flood Vulnerability Assessment of Streams and Stream Crossings at Acadia National Park, Maine Data for an Erosion Potential and Flood Vulnerability Assessment of Streams and Stream Crossings at Acadia National Park, Maine

The U.S. Geological Survey (USGS), in cooperation with the National Park Service (NPS), has compiled Geographic Information Systems (GIS) datasets to assess the erosion potential and flood vulnerability of streams and stream crossings within Acadia National Park, Maine. Erosion potential of streams is estimated using remotely measured geomorphic and hydrologic variables associated with...

A MODFLOW-NWT groundwater-flow model of the Coakley Landfill (CL) area in southeast New Hampshire was constructed from a previously published hydrologic model of the southeast New Hampshire region (https://doi.org/10.5066/P909PUIP). The CL model was used to evaluate groundwater-flow patterns and advective transport pathways from the CL as a proxy to solute transport of per- and...

The U.S. Geological Survey (USGS) used an existing groundwater flow model to determine steady-state groundwater flowpaths from two contaminant plume source areas by using a particle tracking post-processing model (MODPATH; Pollock, 2012) as part of an assessment of potential contaminant discharge at the coast in Bourne, Massachusetts. The extents of the source areas, originating from two...

Seasonal streamflow-metric trends for four United States coastal regions, 1943 through 2022 Seasonal streamflow-metric trends for four United States coastal regions, 1943 through 2022

The streamflow trends in this data release were computed as part of a study on trends in seasonal streamflows relevant to diadromous fish in four United States coastal regions. We investigated seasonal-flow trends at 1,155 gages for eight streamflow metrics from 1973 to 2022 and 89 gages from 1943 to 2022. Two of the regions are on the Pacific coast and two are on the Atlantic coast.

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...

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...

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...
