Probably the most complete study of river water quality w as completed by the U.S. Geological Survey, released in early 1987 and periodically updated. The initial survey was coordinated by Smith and Alexander (USGS) and Wolman (The Johns Hopkins University), including water quality records from two nationwide sampling networks. The network included over 300 locations on the major nvers of the United States. Twenty-four water quality parameters are measured. Originally, the two networks were comprised of (1) the National Stream Quality Accounting Network (NaSQUaN) and (2) the National Water Quality Surveillance System (NWQSS). Locations of stations are shown on the map in Fig. 1. The measured water-quality indicators include ...
