Where does your tap water come from? Because one-third of all Illinois households, farms, and businesses rely on groundwater for their water supplies, there is a good chance your water may come from an underground aquifer. An aquifer is a water-saturated geologic deposit that has enough pores or fractures to supply groundwater to a well, stream, or spring. In Illinois, common aquifers include water-yielding sand and gravel deposits of glacial origin, porous sandstone or fractured limestone, and dolomite bedrock deposits. About 45% of all Illinois water wells tap aquifers in glacial materials, some of which have little protection from contamination.

In partnership with the National Ground Water Association, the ISGS supports Groundwater Awareness Week. This is an opportunity to raise awareness about the importance of our groundwater resources. Join us in protecting groundwater resources by using water wisely (conservation) and by properly disposing of wastes and chemicals (protection).
