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 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

Public Perception Impedes Prevention of Arsenic Exposure

It is estimated that there are over 13 million private wells in the United States, and that about 15 percent of the U.S. population, or over 43 million people, rely on private wells for their drinking water. Arsenic is present in groundwater used for drinking water in several regions of the United States, including the northeastern United States and the adjoining Atlantic Canadian provinces.

One of the biggest challenges in preventing arsenic exposure from drinking water may be public perception, according to a recent special section of Science of the Total Environment.

According to studies completed in Nova Scotia and Maine, testing for arsenic in private wells is often not done because of a low perceived risk for arsenic exposure, inconvenience, and cost of testing. As part of these studies, scientists concluded that the public perception that arsenic is not a health concern prevents actions that could reduce exposure such as water treatment for arsenic removal or development of alternative water sources for private wells.

Our Nation’s Waters


About 130 million people in the United States rely on groundwater for drinking water, and the need for high-quality drinking-water supplies becomes more urgent as our population grows. Although groundwater is a safe, reliable source of drinking water for millions of people nationwide, high concentrations of some chemical constituents can pose potential human-health concerns. More...


The glacial aquifer system underlies much of the northern United States. About one-sixth (41 million people) of the United States population relies on the glacial aquifer system for drinking water. The primary importance of the glacial aquifer system is as a source of water for public supply to the population centers in the region, but the aquifer system also provides drinking water for domestic use to individual homes and small communities in rural areas.

Water use in the United States in 2010 was estimated to be about 355 billion gallons per day (Bgal/d), which was 13 percent less than in 2005. The 2010 estimates put total withdrawals at the lowest level since before 1970. Thermoelectric power and irrigation remained the two largest uses of water in 2010, and total withdrawals for both were notably less than in 2005. Mining and aquaculture were the only major sectors that reported increases in total withdrawals in 2010. More...

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

fact sheet

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

fact sheet

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.

Flood-inundation maps for the Hoosic River, North Adams and Williamstown, Massachusetts

party A series of nine digital flood–inundation maps were developed for an 8–mile reach of the Hoosic River in North Adams and Williamstown, Massachusetts, by the U.S. Geological Survey (USGS) in cooperation with the Federal Emergency Management Agency.
The availability of the flood–inundation maps on the website, combined with information regarding current (near real–time) stage from USGS streamgage Hoosic River near Williamstown, and forecasted flood stages from the National Weather Service Advanced Hydrologic Prediction Service will provide emergency management personnel and residents with information that is critical for flood response activities such as evacuations and road closures, and post–flood recovery efforts. The flood–inundation maps are nonregulatory, but provide Federal, State, and local agencies and the public with estimates of the potential extent of flooding during selected peak–flow events.

USGS Monitors Storm Surge along the Massachusetts coast during the January 2015 Blizzard

Deployed monitoring sites

Deployed monitoring sites

The Blizzard of January 26–28, 2015, contributed to the snowiest 30-day period on record in Boston and surrounding areas. It was a powerful, destructive nor‘easter that led to widespread cancelations and delays at schools, businesses and transportation hubs. A total of 24.6 inches of snowfall and winds up to 45 mph were recorded at the Boston-Logan International Airport. Several coastal communities were impacted with flooding, over wash and damage to seawalls, dwellings and other infrastructure.
Prior to the blizzard, the USGS New England Water Science Center deployed a network of several temporary storm surge sensors (SSS) and barometric pressure sensors along the eastern Massachusetts coast to record the timing and magnitude of storm tide at locations where forecasters had predicted the potential for coastal flooding.

Groundwater Resources of Cape Cod

map The U.S. Geological Survey (USGS) has been investigating groundwater and surface-water resources on Cape Cod for more than 50 years. A newly released USGS Fact Sheet highlights recent studies that have focused on the sources of water to public-supply wells, ponds, streams, and coastal areas; the transport and discharge of nitrogen derived from domestic and municipal disposal of wastewater; and the effects of climate change on groundwater and surface-water resources.
The fact sheet, Science for the Stewardship of the Groundwater Resources of Cape Cod, Massachusetts[] and an associated bibliography of USGS Cape Cod water-resources reports [] are available online.

Hurricane Sandy made the East Coast of the United States realize its vulnerability to extreme tidal surges, coastal flooding and possible impacts of climate change on sea levels and weather. Following this devastating event, the U.S. Geological Survey (USGS) received $18.8 million in supplemental funding to better understand coastal flooding, to improve our preparedness for future coastal storms, and to increase the resilience of coastal cities, infrastructure and natural systems.
