Stronger storms, rising seas, and flooding are placing hundreds of millions people at risk around the world, and big part of the solution to decrease those risks is just off shore. A new study finds that coral reefs reduce the wave energy that would otherwise impact coastlines by 97 percent.

PEMBROKE, N.H. –Nearly 40 percent of New Hampshire's bedrock groundwater likely contains at least low levels of naturally occurring arsenic, according to a new U.S. Geological Survey report.

Reston, Va. – Offshore wind energy development and migratory birds is the topic of a free public lecture Wednesday, December 5, at 7 p.m. at the U.S. Geological Survey National Center in Reston, Va. 

PEMBROKE, N.H. -- A new flood preparedness tool that will help emergency managers improve flood warnings and response is now available for a 16.5-mile reach of the Suncook River in southeastern New Hampshire that has frequently flooded adjacent homes.

The low streamflows seen throughout much of New England this April do not foreshadow a summer drought, as researchers have determined summer rainfall plays a bigger role than snowmelt runoff in determining streamflows in the summer. 

The February 25 storm that brought heavy rain and wind to the area resulted in high flows for southeastern New Hampshire rivers, according preliminary estimates released today by the U.S. Geological Survey (USGS). 

The March 14-15 storm that brought rains of 7 inches or more in southeastern New Hampshire caused stream flooding throughout the Seacoast and southern regions of the state, according to preliminary estimates released today by the U.S. Geological Survey (USGS). 

Levels of chloride, a component of salt, are elevated in many urban streams and groundwater across the northern U.S., according to a new government study. Chloride levels above the recommended federal criteria set to protect aquatic life were found in more than 40 percent of urban streams tested. The study was released today by the U.S. Geological Survey (USGS).

Increased demand for water and a warmer climate will likely decrease the amount of water available in the streams and aquifers of southeast New Hampshire's Seacoast region. Summer stream flows could be 10 percent less by 2025 than they are now and groundwater levels will likely drop if demand continues to grow as projected.

U.S. Geological Survey Deputy Director Robert Doyle has been selected as a Distinguished recipient of the Presidential Rank Award, a prestigious award that commends outstanding leadership and long-term accomplishments.

By 2025, demand for water in the Seacoast Region of New Hampshire is expected to grow by more than 50 percent. In the past five years, water use was estimated at 26.3 million gallons per day. By 2025, the demand may be more than 40 million gallons per day. These findings were released today by the U.S. Geological Survey.
