Scale: 1:40,000 Sand and gravel aquifers may be locally important (Lg) or regionally important (Rg). Rg A sand/gravel aquifer is classed as regionally important if it can supply regionally important abstractions (e.g. large public water supplies with ‘excellent’yields >400 m3/d).

2021-11-16 ABSTRACT Groundwater is a nearly exclusive water resource, specifically for the communities which are part of the Chicago metropolitan area. However, water shortage is predicted for many communities in this region, and demand for locating and delineating groundwater is increasing to fulfill the water supply.

Most shallow aquifers in sand and gravel deposits produce lower yields, but they can be rapidly recharged. Some deep aquifers are known as “fossil waters”. The term “fossil” describes water that has been present for several thousand years.
