Unified Interior Regions

A study by the U.S. Geological Survey has found that potentially more than 103,000 people who use private wells for drinking water in parts of eastern New England could have water supplies with arsenic levels that are higher than federal standards.

A very minor earthquake, preliminary magnitude 2.9 according to the U.S. Geological Survey, occurred today in southeastern New Hampshire at 9:50 am Eastern Standard Time. The epicenter was near Raymond, NH. The earthquake was felt in Raymond. The USGS has received no reports of damage.

Water quality has improved significantly in New England over the past 50 years because of advances in the treatment of municipal and industrial wastes.

State-of-the-art tools, such as radar and video cameras and other techniques, were used to describe fractured bedrock aquifers and determine the direction of water flowing in rocks underlying Seabrook and Rye, New Hampshire. The advanced methods and tools that were used are highlighted in recently published reports by the U.S. Department of the Interior, U.S. Geological Survey (USGS).

Research on how cracks, or fractures, in the earth’s bedrock are distributed and the relations between fractures in rock exposed and beneath the surface, rock type, and the capacity of these fractures to bear water was done on bedrock aquifers near Mirror Lake, Grafton County, New Hampshire.

Volunteer Bird Watchers are Key to Continent-Wide Survey’s Success: Each year, over a short period of time in early spring, a well-organized network of more than 2500 skilled amateur birders and professional biologists participate in the North American Breeding Bird Survey (BBS).

Ground water flows through Earth’s materials and people usually are interested in locating this ground water for drinking.

As fall foliage begins to blanket New Hampshire, pleasantly diverting the attention of residents and visitors, scientists are preparing to unveil some of the geologic secrets of the famous yet not-well-known rocks that lie beneath the fiery cover.
