New national water quality monitoring network


  • Anonymous


The National Stream Quality Accounting Network (NASQAN), a new water quality monitoring network designed to provide a balanced yearly picture of water quality in U.S. streams on a national and regional scale, is now in operation according to the U.S. Geological Survey. Its primary objectives are to account for the quantity and quality of water moving within and from the United States, to depict areal variability of water quality, to detect changes in stream quality, and to lay the groundwork for future assessments of changes in stream quality.

In the past, attempts to document change or lack of change in water quality with time have been largely unsuccessful because of incomplete or inadequate data. Because NASQAN is set up on a national basis, has stations that are operated uniformly, and has a program that is committed to long-term objectives, it should not have these problems.
