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.

Data related to the degree of potential human influence near 2228 groundwater wells in the U.S. glacial aquifer system Data related to the degree of potential human influence near 2228 groundwater wells in the U.S. glacial aquifer system
This dataset contains information on the degree of potential human influence near 2228 groundwater wells in the U.S. glacial aquifer system. Data include well identification, name, latitude, longitude, potential-human-influence category, percent urban and crop land use in a 500 meter radius around each well, and measures of county-based groundwater use and irrigation.
Temperature and seepage data from a lake-bottom permeable reactive barrier, Ashumet Pond, Falmouth, MA, 2004-2015. Temperature and seepage data from a lake-bottom permeable reactive barrier, Ashumet Pond, Falmouth, MA, 2004-2015.
These data were collected to evaluate groundwater/surface-water exchange in the area of a lake-bottom permeable reactive barrier and to assess changes in groundwater seepage over the period between 2004 and 2015. This data release includes geospatial datasets, comma separated values (.csv) files, and associated FGDC-compliant metadata representing data collected between 2004 and 2015 as...
Velocity, depth, and selected water quality profiles of the Lower Penobscot River Estuary in Maine, 2017 Velocity, depth, and selected water quality profiles of the Lower Penobscot River Estuary in Maine, 2017
This data release includes transect data comprising velocity and depths collected by use of an acoustic-doppler current profiler (ADCP), and vertical profile data comprising conductivity, temperature, and depth by use of a conductivity, temperature, and depth (CTD) instrument, as well as tide elevation data at specified locations in the lower Penobscot River and Penobscot Bay (the...
Precipitation and streamflow data for computing lag to peak at selected stations in Maine Precipitation and streamflow data for computing lag to peak at selected stations in Maine
These are rainfall and stream stage data collected at gaging sites in Maine. Data were collected from March to October from 2008 to 2015 and include stage data at crest stage gages, ratings to convert stage data to streamflow data, previously unpublished rainfall data, rainfall binned into specified time intervals, and storm files combining rainfall and streamflow data. Data were...
Thirty- and ninety-year data sets of streamflow, groundwater recharge, and snowfall simulating potential hydrologic response to climate change in the 21st century in New Hampshire Thirty- and ninety-year data sets of streamflow, groundwater recharge, and snowfall simulating potential hydrologic response to climate change in the 21st century in New Hampshire
The U.S. Geological Survey (USGS), in cooperation with the New Hampshire Department of Environmental Services (NHDES) and the Department of Health and Human Services (NHDHHS), has developed tools to assess the effects of short- and long-term climate change on hydrology in New Hampshire. A USGS Scientific Investigations Report (SIR) report documents tools and datasets developed by the...
Estimates of annual and daily concentration and flux of nutrients, chloride, and suspended sediment in tributaries of Lake Champlain, 1990 through 2014 Estimates of annual and daily concentration and flux of nutrients, chloride, and suspended sediment in tributaries of Lake Champlain, 1990 through 2014
Daily and annual estimates of concentrations and flux of total and dissolved phosphorus, total nitrogen, chloride, and total suspended solids are provided for the period March 1990 through November 2014 (or for less time, depending on data availability) for use in watershed models and to support trend assessments.
Concentrations of arsenic in water from public supply and domestic wells in New Hampshire Concentrations of arsenic in water from public supply and domestic wells in New Hampshire
This dataset contains arsenic concentrations from bedrock aquifer wells located throughout New Hampshire and includes public supply wells and domestic supply wells.
Inventory of arsenic and uranium water-quality results from private wells in Connecticut, 2013-2015 Inventory of arsenic and uranium water-quality results from private wells in Connecticut, 2013-2015
This dataset contains the water-quality results from the testing of unfiltered water samples collected from 674 private wells in Connecticut for the analysis of arsenic and (or) uranium, using EPA method 200.8. All of the environmental water-quality data and georeferenced locations of the sampled wells were provided by the Connecticut Department of Public Health (CT-DPH). The water...
Testing dataset for independent analysis of New Hampshire arsenic model Testing dataset for independent analysis of New Hampshire arsenic model
Existing multivariate logistic regression models that predict the probabilities of arsenic concentrations at 1, 5, and 10 micrograms per liter in bedrock aquifers of New Hampshire were tested using bedrock wells not included in the model development. This data release contains a table of measured arsenic concentrations and associated model input variables for the model testing dataset...
Model climate scenario output for the Farmington river basin, Connecticut and Massachusetts, 2036-2065 change from 1975-2004, Representative Concentration Pathways 4.5 and 8.5 Model climate scenario output for the Farmington river basin, Connecticut and Massachusetts, 2036-2065 change from 1975-2004, Representative Concentration Pathways 4.5 and 8.5
This data release provides a set of Hydrological Simulation Program--Fortran (HSPF) model files representing five EPA-selected future climate change scenarios for the Farmington River Basin in Massachusetts and Connecticut. Output from these models are intended for use as input to EPA Watershed Management Optimization Support Tool (WMOST) modeling. Climate scenarios, based on 2036-2065...
Bedrock well yield, lineaments, and ancillary data in the Nashoba Terrane, central and eastern Massachusetts Bedrock well yield, lineaments, and ancillary data in the Nashoba Terrane, central and eastern Massachusetts
This data release contains well yield and ancillary data for 7,287 bedrock wells used in an analysis of bedrock well yield in the Nashoba Terrane and surrounding area in eastern and central Massachusetts. The data release also contains Geographic Information System (GIS) data layers of lineaments delineated from aerial photographs and digital elevation data for a part of the Nashoba...
Estimated county level domestic well population with arsenic greater than 10 micrograms per liter based on probability estimates for the conterminous U.S. Estimated county level domestic well population with arsenic greater than 10 micrograms per liter based on probability estimates for the conterminous U.S.
Arsenic concentrations from 20,450 domestic wells in the U.S. were used to develop a logistic regression model of the probability of having arsenic > 10 g/L (high arsenic). We use only domestic well arsenic data and a national-scale modeling approach. This approach expands our understanding of potential exposure to arsenic in drinking water to a national scale and allows inter-regional...
