Project Title: National Water Quality Assessment of the Upper Mississippi River Basin
The objectives of this study are to describe the status and trends in the quality of a large representative part of the Upper Mississippi River Basin's surface and ground-water resources and to provide scientific understanding of the primary natural and human factors affecting the quality of these resources. The program began in 1993 in the UMIS basin. In 2001, the NAWQA Program begins its second decade (Cycle-2) of intensive water-quality assessments, which will build upon initial assessments of water-quality conditions and increase understanding of long-term trends and the factors that affect water quality. The Cycle-2 sampling included continued sampling of two streams on a rotating schedule and 17 wells that are sampled biennially as trend sites. In addition, the nutrient enrichment effects study was conducted in the UMIS to understand how nutrient conditions affect biological responses in agricultural areas.
