Data
The New England Water Science Center operates over 500 real-time data collection sites throughout the six New England states. The sites collect surface-water, groundwater, water-quality, and precipitation data. Much of our real-time data is publicly available through NWIS. Additional data releases are also available on the page below.

Hydraulic models and supplementary data for 30 stream crossing sites in Massachusetts Hydraulic models and supplementary data for 30 stream crossing sites in Massachusetts
The data in this Data Release are used to calibrate a Geographic Information System (GIS) based hydraulic modeling tool developed by the U.S. Geological Survey (USGS) for Massachusetts in cooperation with the Massachusetts Department of Environmental Protection (MassDEP). USGS developed one-dimensional U.S. Army Corps of Engineers (USACE) Hydrologic Engineering Center’s River Analysis...
Housatonic River watershed hydraulic models and supplementary data for stream crossings in Massachusetts Housatonic River watershed hydraulic models and supplementary data for stream crossings in Massachusetts
The U.S. Geological Survey (USGS), in cooperation with the Massachusetts Department of Environmental Protection (MassDEP), developed one-dimensional U.S. Army Corps of Engineers (USACE) Hydrologic Engineering Center’s River Analysis System (HEC-RAS) hydraulic models for stream crossing sites in the Housatonic River watershed, Massachusetts. An automated Geographic Information System (GIS...
Solid/Water Partitioning of Per- and Polyfluoroalkyl Substances (PFAS) in New Hampshire Soils and Biosolids: Results from Laboratory Experiments at the U.S. Geological Survey Solid/Water Partitioning of Per- and Polyfluoroalkyl Substances (PFAS) in New Hampshire Soils and Biosolids: Results from Laboratory Experiments at the U.S. Geological Survey
Data from a laboratory study undertaken at the U.S. Geological Survey to investigate solid/water partitioning of per- and polyfluoroalkyl substances (PFAS) in New Hampshire soils and biosolids are presented here. Soils and biosolids used for the experiments were collected using PFAS-free sampling equipment, air dried, gently homogenized, and sieved (soils only). Soil samples were...
Data and model archive for shallow soil PFAS predictions in Maine, New Hampshire, and Vermont, 2026 Data and model archive for shallow soil PFAS predictions in Maine, New Hampshire, and Vermont, 2026
Anthropogenic background concentrations of per- and polyfluoroalkyl substances (PFAS) in shallow soils (zero to six inches in depth) across Maine, New Hampshire, and Vermont are compiled in this data release, together with a summary table of soil PFAS method detection limits. New Hampshire samples were collected in 2021 (Santangelo and others, 2022), Vermont samples were collected in...
Per- and Polyfluoroalkyl Substances (PFAS) in Tapwater From Private Wells in Clinton County, Iowa, and Whiteside County, Illinois, 2024 Per- and Polyfluoroalkyl Substances (PFAS) in Tapwater From Private Wells in Clinton County, Iowa, and Whiteside County, Illinois, 2024
Between June 2024 and December 2024, tapwater samples were collected from 48 homes that use private well water as their drinking water source. All homes were located within a 50-kilometer radius of the 3M Cordova Facility in Cordova, Illinois, and analyzed for per- and polyfluoroalkyl substances (PFAS). The sampling effort was undertaken by the University of Iowa and samples were sent to...
Surface-water-quality data collected in mountaintop mining areas of West Virginia and Kentucky in 2023 Surface-water-quality data collected in mountaintop mining areas of West Virginia and Kentucky in 2023
In 2023, the U.S. Geological Survey conducted a reconnaissance survey of surface-water quality in areas of southern West Virginia and eastern Kentucky that have ongoing and/or historic mountaintop removal mining for coal resources. The water-quality data collected during the survey are collated in this data release.
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...
MODFLOW-NWT and MODPATH6 files used for groundwater-flow simulation and pathline analyses in the vicinity of the Coakley Landfill Superfund site, Rockingham County, New Hampshire MODFLOW-NWT and MODPATH6 files used for groundwater-flow simulation and pathline analyses in the vicinity of the Coakley Landfill Superfund site, Rockingham County, New Hampshire
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...
MODPATH Model Used to Evaluate Flowpaths from Two Contaminant Plume Source Areas near Joint Base Cape Cod, Western Cape Cod, Massachusetts MODPATH Model Used to Evaluate Flowpaths from Two Contaminant Plume Source Areas near Joint Base Cape Cod, Western Cape Cod, Massachusetts
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.
Soil-Water-Balance (SWB) Model Archive Used to Simulate Potential Recharge with Projections for Future Climate Scenarios, Saco River Basin, Maine and New Hampshire Soil-Water-Balance (SWB) Model Archive Used to Simulate Potential Recharge with Projections for Future Climate Scenarios, Saco River Basin, Maine and New Hampshire
This model archive makes available the Soil-Water-Balance (SWB) model used to simulate potential recharge for the Saco Headwaters Watershed. This model was used to simulate potential recharge (net infiltration) for use in a groundwater model in the same region to understand the effects of water bottling. The model was used to produce a historical simulation (2000 -2021) and a series of...
MODFLOW 6 Datasets for a Groundwater-flow Model in the Saco River Basin, New Hampshire and Maine MODFLOW 6 Datasets for a Groundwater-flow Model in the Saco River Basin, New Hampshire and Maine
A MODFLOW 6 groundwater model for the Wards Brook aquifer in New Hampshire and Maine was developed to understand the effects of groundwater withdrawals for historical and potential future conditions. The model assesses how groundwater withdrawals, including for bottled water, affect base flows from Wards Brook, groundwater levels, and pond levels under different scenarios. Model runs...
