The Usgs Illinois Water Science Center Office in Urbana, IL conducts scientific investigations and research on the hydrochemical regions of the glacial aquifer system in the northern United States. They analyze ground-water quality on a regional scale to understand variations in water composition and its relationship to the geologic and physical environment. Through data analysis and spatial modeling, they have identified five hydrochemical regions within the glacial aquifer system, providing valuable insights into water quality characteristics in different areas.
Their research findings indicate that variations in water quality can be explained by environmental factors such as land use, soil permeability, and precipitation. They have observed significant differences in the concentrations of major and minor ions, as well as trace elements, among the hydrochemical regions. This information is crucial for understanding the intrinsic susceptibility and vulnerability of the glacial aquifer system, which can help in managing and protecting water resources in the region.
