Abstract

This report contains the major findings of a 1999–2001 assessment of water quality in the New England Coastal Basins. It is one of a series of reports by the National Water-Quality Assessment (NAWQA) Program that present major findings in 51 major river basins and aquifer systems across the Nation.

 

In these reports, water quality is discussed in terms of local, State, and regional issues. Conditions in a particular basin or aquifer system are compared to conditions found elsewhere and to selected national benchmarks, such as those for drinking-water quality and the protection of aquatic organisms.

 

This report is intended for individuals working with water-resource issues in Federal, State, or local agencies, universities, public interest groups, or in the private sector. The information will be useful in addressing a number of current issues, such as the effects of agricultural and urban land use on water quality, human health, drinking water, source-water protection, hypoxia and excessive growth of algae and plants, pesticide registration, and monitoring and sampling strategies. This report is also for individuals who wish to know more about the quality of streams and ground water in areas near where they live and how that water quality compares to the quality of water in other areas across the Nation.

 

The water-quality conditions in the New England Coastal Basins summarized in this report are discussed in detail in other reports that can be accessed from http://nh.water.usgs.gov/CurrentProjects/nawqa/nawqaweb.htm. Detailed technical information, data and analyses, collection and analytical methodology, models, graphs, and maps that support the findings presented in this report in addition to reports in this series from other basins can be accessed from the national NAWQA Web site (http://water.usgs.gov/nawqa).

Effects of Population Growth and Urbanization on Water Quality

Major Findings

Urbanization Results in Significant Degradation of Stream Ecosystems

REGIONAL PERSPECTIVE—Stream Quality Degrades as Urbanization Increases in
Four Major Metropolitan Areas

Many Trace Elements and Organic Contaminants were Detected in Streambed Sediments

Cores Reveal 50 Years of Elevated PAHs in Streambed Sediments of the Charles River

Organochlorine Compounds in Fish May Pose a Threat to Fish-Eating Wildlife

NATIONAL PERSPECTIVE—Concentrations of Lead, PCBs, DDT, and PAHs in Streambed Sediments were the Highest in the Nation

Mercury Contamination is Widespread in Streambed Sediments and Fish Tissue

NATIONAL PERSPECTIVE—Coastal Ecosystems in the Eastern United States are Highly Susceptible to Mercury Contamination

VOCs were Detected Frequently in Rivers and Ground Water

NATIONAL PERSPECTIVE—VOCs are Detected More Frequently in the New England Coastal Basins than in the Rest of the Nation

Pesticides were Detected Frequently in Streams but Rarely in Ground Water

Nitrogen and Phosphorus Concentrations in Streams are Related to Urbanization

Drinking-Water Standard for Nitrate Rarely Exceeded in Ground Water

Arsenic is Common in New England Ground Water

Radon Exceeded Proposed Standards in Most Ground Water

NATIONAL PERSPECTIVE—Arsenic is Common in Ground Water Throughout the Nation
