New
England Water is Improving But Problems Remain, Says New USGS Report
Water quality has improved
significantly in New England over the past 50 years because of advances
in the treatment of municipal and industrial wastes. However, New Hampshire,
Maine, Massachusetts, and Rhode Island are still experiencing some problems
with the quality of ground and surface water and the water in the Gulf
of Maine. In an effort to better understand the current picture, the U.S.
Geological Survey (USGS) has released a report that describes the natural
and human factors that affect water quality and aquatic life in New England.
"Problems with water
quality are due to many factors," said Keith Robinson, Chief of the
New England Coastal Basins study. These factors range from excess nutrient
concentrations to toxic substancs, land use and sewer overflows, the presence
of syntheticorganic chemicals, effects of dams on fish and bottom-dwelling
organisms, effects of the depostion of mercury from the atmposphere into
lakes and fish, and the direct and indirect sources of pollutants in rivers.
The USGS report describes
the geology, climate, soils, rivers and streams, ground waters, plant
and animal habitats on land and in the water, and human settlement and
industry (termed environmental settings) within the 23,000-square-mile
New England Coastal Basins study area.
Information about the physical
and cultural characteristics, or environmental setting, will not only
give a picture of the quality of surface and ground water but also provide
information needed by water-resource managers in the four states to implement
effective water-quality management policies.
The New England study is one
of 59 similar studies being conducted nationwide to define how the environment
influences ground and surface-water quality and aquatic biology in large
watersheds, or drainage areas, as part of the National Water-Quality Assessment
Program.
Copies of the report Water-Resources
Investigations Report 98-4249, titled "Water-quality assessment of
the New England Coastal Basins in Maine, Massachusetts, New Hampshire,
and Rhode Island: Environmental settings and implications for water quality
and aquatic biota," by S.M. Flanagan and others, are available for
viewing at university, state, and government depository libraries and
at the USGS, NH/VT District office, 361 Commerce Way, Pembroke, NH 03275,

As the nation's largest water,
earth and biological science, and civilian mapping agency, the USGS works
in cooperation with more than 2,000 organizations across the country to
provide reliable, impartial, scientific information to resource managers,
planners, and other customers. This information is gathered in every state
by USGS scientists to minimize the loss of life and property from natural
disasters, contribute to the sound conservation, economic and physical
development of the nation's natural resources, and enhance the quality
of life by monitoring water, biological, energy, and mineral resources.
