Description In 2001, the U.S. Geological Survey's (USGS) National Water-Quality Assessment (NAWQA) Program began its second decade of intensive water-quality assessments (Cycle II). NAWQA scientists plan to revisit 42 major river-basin and aquifer systems that were assessed in the first decade. The NAWQA Program is a primary source for long-term, nationwide information on the quality of streams, ground water, and aquatic ecosystems. The goals of NAWQA are to assess the status and trends of water quality and to understand the factors that affect it, thus addressing the questions, What is the condition of our Nation's streams and ground water? How is water quality changing over time? How do natural features and human activities affect the quality of streams and ground water? For Cycle II assessments, study units were selected that represent a wide range of important hydrologic environments; contain critical contaminant sources, including agricultural, urban, and natural sources; and include more than 60 percent of national water use for drinking and irrigation. Many of the predominantly agricultural study units and most of the large urban areas included in the first cycle of NAWQA assessments were retained for Cycle II. Central Nebraska s one of the most intensively agricultural areas being examined in Cycle II, as determined from the extent of agricultural land and intensity of estimated pesticide and fertilizer use.
