Abstract:
This map shows the distribution of major bedrock aquifer units within 300 feet of ground surface containing potable water in Illinois. Major aquifers are capable of yielding 70 gallons of water per minute. Potable water contains less than 2,500 milligrams per liter of total dissolved solids. Bedrock aquifers within 300 feet of ground surface cover most of northern Illinois and are commonly overlain only by thin layers of less permeable silts and clays. Many are directly overlain by shallow or major sand and gravel aquifers allowing direct hydrologic communication with shallower aquifer systems. Stratigraphic units considered to be major bedrock aquifers are: Hunton Limestone Megagroup Ancell Group Prairie du Chien Group Ironton-Galesville Sandstone Elmhurst-Mt. Simon Sandstone Coverage is intended to identify areas of Illinois where major bedrock aquifers exist. These data are appropriate for regional thematic analysis.
