Abstract
The preface of a slide presentation at the conference is the abstract.
The initial six-year phase (1994-99) of the Upper Mississippi River National Water-Quality Assessment (NAWQA) study focuses on data collection and analysis in a 19,000 square-mile area of Minnesota and Wisconsin that includes the Twin Cities metropolitan area. The study design focuses on factors that have an influence, or a potential influend on ground- and surface-water quality. The most significant water-quality issues include concern about nutrients, pesticides, synthetic-organic chemicals, and heavy metals. The study area was divided into subareas with homogenous natural and human characteristics to assess natural and anthropogenic factors affecting water quality. Water quality in those subareas (aquifers and stream basins) will be assessed by comparing water quality in streams and in aquifers between the subareas.
