Water Quality in the Nation's Stream and Rivers
Description / purpose
In 1991, Congress established the National Water-Quality Assessment (NAWQA) Project to address where, when, why, and how the Nation's water quality has changed, or is likely to change in the future, in response to human activities and natural factors. A prominent feature of NAWQA is the development of long-term consistent and comparable information on streams, rivers, ground water, and aquatic systems. The NAWQA Project is designed to answer these questions:
1. What is the current condition of our Nation's streams, rivers, and groundwater?
2. How are these conditions changing over time?
3. How do natural features and human activities affect these conditions, and where are those effects most pronounced?
Under the National Water-Quality Assessment (NAWQA) project, there are several surface water and ecology studies, including the Regional Stream Quality Assessment (RQSA) (a baseline assessment of streams), and current conditions and long-term trends monitoring.
