Water Quality in the Great and Little Miami River Basins, Ohio and Indiana, 1999-2001,
  press release, frequently asked questions (FAQs), and photos.

In 1991, the U.S. Geological Survey began the National Water-Quality Assessment (NAWQA) Program. The long-term goals of the NAWQA Program are to describe the status and trends in the water-quality of a large, representative part of the Nation's surface- and ground-water resources and to provide a sound scientific understanding of the primary natural and human factors affecting the quality of these resources.

The Great and Little Miami River Basins is one of more than 50 major river and aquifer systems-termed "study units" chosen by the NAWQA Program to represent the diverse geography, water resources, and land and water uses in the Nation. The Great and Little Miami River Basins (MIAM) study unit is one of the NAWQA studies that began in 1997. Initial collection of water-quality and ecological data began in September 1998.

In October 2000, the Great and Little Miami River Basins study unit was merged with the White River Basin study unit.
