- Abstract
- The rapid increase in population and developed land in the Chicago, Illinois, metropolitan area has put a heavy demand on water resources. The water sources most likely to be exploited in this region over the next few decades are shallow aquifers. These shallow aquifers are vulnerable to surface-derived contaminants, and the increase in developed land may be increasing the rate at which ground-water quality is being degraded. Historical ground-water quality data from the Chicago metropolitan area is being evaluated for data quality and temporal trends. Preliminary results indicate increases in the concentrations of most major ions, especially chloride, both regionally and for individual wells. Chloride concentrations have increased by over 4 mg L-1 yr-1 in a significant number of municipal wells. Changes appear to be most rapid in the outermost counties of the Chicago metropolitan area.
