Scope of the Long Island-New Jersey Coastal Drainages Study-Unit Investigation
In 1991, the U.S. Geological Survey (USGS) began a National Water-Quality Assessment (NAWQA) Program to document the status of and trends in quality of a large representative part of the Nation's water resources and to provide a sound scientific understanding of the primary natural and human factors that affect the quality of these resources. The program is designed to produce long-term, consistent water-quality information that will be useful to policymakers and managers at national, State, and local levels.
Investigations of 60 hydrologic systems (study units), which include parts of most major river basins and aquifer systems in the United States, are the building blocks of NAWQA. A framework has been established to ensure nationwide consistency in the approach to each study--in field and laboratory methods, in water-quality measurements, and in the supporting data requirements. Twenty studies were started in 1991, 20 more have begun in 1994, and 20 are scheduled to begin in 1997.
A major design feature of the program that will facilitate integration of water-quality information at national, regional, and local scales is coordination between the individual study-unit teams and the national synthesis effort at all stages of the investigations. Thus, results that relate to various topics addressed in the study-unit investigations will be integrated smoothly into NAWQA's national synthesis component. Teams have been developed to address the following topics of national importance: pesticides, nutrients, and volatile organic compounds. These teams are investigating the specific issues by means of comparative studies of a large set of hydrologic systems distributed over a wide range of environmental settings found in the 60 study-units.
The information below summarizes the goals and scope of the NAWQA Program and the Long Island-New Jersey Coastal Drainages study, which began in 1994.
