Water Resources of New England

New England Water Science Center website provides information on New England's rivers and streams, groundwater, water quality, and biology. Data collection and interpretive studies done by the Center are part of the U.S. Geological Survey (USGS) science strategy to address the water resource priorities of the Nation in:

  • Ecosystem status and change
  • Climate variability and change
  • National hazard risk and assessment
  • Environmental risk to human health
  • Water use and availability
  • Transportation activities in relation to water resources

Flood-inundation Maps Presentations

The U.S. Geological Survey will be making presentations on a recent study that developed online real-time flood-inundation maps.

The mainstem Pawtuxet River in Cranston, Warwick, and West Warwick, Rhode Island incurred historic flooding during late March and early April 2010. The U.S. Geological Survey in cooperation with Rhode Island Emergency Management and the U.S. Army Corps of Engineers developed real-time flood-inundation maps for the mainstem of the Pawtuxet River, which are tied to the USGS Pawtuxet River at Cranston streamgage (01116500).

The lower Pawcatuck River in Westerly, Rhode Island and North Stonington and Stonington, Connecticut incurred historic flooding during late March and early April 2010. The U.S. Geological Survey in cooperation with the Town of Westerly, Rhode Island, and the Rhode Island Office of Housing and Community Development developed real-time flood-inundation maps for the lower Pawcatuck River (riverine flooding only), which are tied to the USGS Pawcatuck River at Westerly, RI streamgage (01118500).

The maps can be viewed on the USGS flood-inundation mapper at

The mainstem Pawtuxet River flood-inundation mapping study report is available at The lower Pawcatuck River flood-inundation mapping study report is available at

There is a brief description of the study for Pawcatuck and Pawtuxet.

There are two presentations scheduled for each study. Each presentation will be about 45 minutes long; with about a 20 minutes overview of flood-inundation mapping and this study, followed by about a 10-15 minute demonstration of the online mapper, and then a 10-15 minute period for questions.
Both presentations are open to the public.

Study Estimates about 2.1 Million People using Wells High in Arsenic.

In 2016 the New England WSC has published 5 new fact sheets that highlight our work and capabilities in 5 topics: flood- and drought-related natural hazards, groundwater quality, surface-water quality, climate change influences, and transportation activity impacts on hydrology. These 5 areas of work are critically related to water resource protection and assessment in New England.

USGS Deploys Storm-Tide Sensors in Advance of Nor'Easter
Released: 03/01/2018

USGS field crews have deployed storm-tide and wave sensors from Maine to Delaware to track and study a Nor'easter. These sensors will continuously measure wave height and tide levels and provide information on the timing, duration and extent of flooding. Data is collected four times per second, providing a detailed picture of the storm.

Study Estimates about 2.1 Million People using Wells High in Arsenic
Released: 10/18/2017

A new study by the U.S. Geological Survey and Centers for Disease Control and Prevention estimates about 2.1 million people in the U.S. may be getting their drinking water from private domestic wells considered to have high concentrations of arsenic, presumed to be from natural sources.

Study Links Major Floods in North America and Europe to Multi–Decade Ocean Patterns
Released: 8/10/2017

The number of major floods in natural rivers across Europe and North America has not increased overall during the past 80 years, a recent study has concluded. Instead researchers found that the occurrence of major flooding in North America and Europe often varies with North Atlantic Ocean temperature patterns. Read more ...

Threats to groundwater availability and sustainability in the Northern Atlantic Coastal Plain are dependent to a large degree by the type of aquifers used for water supply, according to a new regional assessment by the U.S. Geological Survey. Read more ...

Cape Cod susceptible to potential effects of sea-level rise
Released: 7/12/2016

Cape Cod is vulnerable to rising water tables and, in some areas, groundwater inundation as a result of rising sea levels, according to a new U.S. Geological Survey study.
Groundwater inundation occurs when the water table reaches or exceeds land surface. The challenges associated with the issue are likely to become more prevalent as seas rise. In some communities, groundwater inundation may result in saltwater intrusion of aquifers, problems with underground utilities and pipes, flooded basements and septic system failures, among other challenges. Depending on the severity, it may make areas unsuitable for residential and commercial development. Read more ...

A Decade of Water Science: USGS Helps Assess Water Resources in Afghanistan
Released: 8/19/2014

For the past decade, scientists from the U.S. Geological Survey have shared their expertise with the Afghanistan Geological Survey (AGS) in efforts to build an inventory of Afghanistan’s water resources. A new fact sheet details how these efforts help the country quantify and monitor its water resource.
”This partnership with the Afghanistan Geological Survey and other international agencies is extremely important for Afghanistan,” said Jack Medlin, USGS regional specialist, Asia and Pacific Region. ”There’s a broad consensus that water availability is a global issue, and these collaborative efforts created the data collection networks necessary to help quantify water conditions in the region and manage future water supplies.” Read more ...

Well-Water for 80,000 New Hampshire Residents May contain Metals Exceeding Human Health Standards
Released: 6/16/2014

Nearly three-in-ten well-water samples tested from southeast New Hampshire contained metals at concentrations that exceeded U.S. Environmental Protection Agency drinking-water standards and guidelines, according to a recent U.S. Geological Survey study.
Researchers sampled water from 232 private bedrock wells from 2012 to 2013, testing for levels of arsenic, uranium, manganese, iron and lead.
”Our study showed that a significant percentage of the population that relies on domestic bedrock wells may have drinking water with arsenic, lead, manganese, and (or) uranium concentrations greater than human-health standards established by the EPA for public-water systems,” said hydrologist Sarah Flanagan, lead author of the study.
