Abstract

A test drilling program was completed in 1992 to provide a better understanding of the aquifer system. Sixteen wells were installed to monitor water-level fluctuations in this lowermost basal sand-and-gravel aquifer composed predominantly of Sankoty-Mahomet Sand. The drilling results indicate the very complex geologic framework of the system. Data from the latest drilling program indicated differences in bedrock elevations of as much as 75 feet from elevations in earlier bedrock surface maps of the area. The conceptual model of the confluence area is notably different from earlier interpretations. The potentiometric surface map generated from measurements of private wells indicates that ground water flows both westward toward the Illinois River and northward into the Mackinaw Valley from the confluence area. -from Authors
