Abstract
The water-level decline from 1962 through 1966 in deep wells penetrating the Cambrian-Ordovician aquifer, the most highly developed aquifer for large groundwater supplies in northeastern Illinois, is considered in this report. The Cambrian-Ordovician aquifer is encountered at an average depth of about 500 feet below the land surface at Chicago; it has an average thickness of 1000 feet and is composed chiefly of sandstones and dolomites. Withdrawals since 1961 exceeded the practical sustained yield of the Cambrian-Ordovician aquifer, as they have each year since 1958, with the result that groundwater users in the Chicago region continue to mine water and to borrow water from future generations.
