Hydrogeology of glacial deposits of the Mahomet Bedrock Valley in east-central IllinoisManufacturer: Illinois State Geological Survey. The buried Mahomet Valley in east-central Illinois is a complex lowland carved into the surface of Pennsylvanian and older rocks. It consists of a deep channel throughout most of its length and contains numerous benches below erosional remnant hills, suggesting several cycles of early to middle Quaternary erosion. 4 Bedrock geology of east-central Illinois 8 5 Bedrock valleys of east-central Illinois 9 6 Surface Quaternary deposits of Illinois 10 7 Drift thickness of part of east-central Illinois including the study area 11 8 Sequence of glacial deposits from the study area into northern Vermilion County Andrew Stumpf, Associate Quaternary Geologist for the Illinois State Geological Survey (ISGS), recently completed a map product titled Geologic Cross Sections Across the Mahomet Bedrock Valley, Champaign, Ford, McLean, Piatt, and Vermilion publication is an outcome of research conducted in east-central Illinois that was funded by a private water supply company .

The Lafayette Bedrock Valley System is a complex of bedrock valleys that converge on and diverge from Lafayette, Indiana. The primary trunk valley of the system, composed of the narrow Marion Valley Section on the east and the broad Mahomet Valley Section on the west, is the classic “Teays Valley” of the Midwest.

OF SAND AND GRAVEL AQUIFERS FOR MUNICIPAL GROUNDWATER SUPPLIES IN EAST-CENTRAL ILLINOIS ABSTRACT Glacial sand and gravel aquifers have been identified strati-graphically and mapped in a by mile rectangular area of east-central Illinois. Located within the area are several water-short communities as well as the cities of Danville.

The Mahomet Aquifer is the most important aquifer in east-central ed of sand and gravel, it is part of the buried Mahomet Bedrock underlies 15 counties and ranges from 50 to feet (15 to 60 m) thick. It supplies over ,, US gallons (, m 3) per day of groundwater for public water use, industrial supply, and irrigation. Major aquifers are defined as geologic units capable of yielding 70 gallons of potable water per minute. Potable water is defined as containing less than 2, milligram per liter total dissolved solids. Major sand and gravel aquifers are generally Quaternary deposits found within pre-glacial bedrock valleys or along modern streams and rivers. The Troy Bedrock Valley (TBV) and its tributary valleys are the principal pre-glacial drainage in southern Wisconsin and northern Illinois, USA. This study focused on the headwaters of a . The Troy Bedrock Valley (TBV) and its tributary valleys are the principal pre-glacial drainage in southern Wisconsin and northern Illinois, USA. This study focused on the headwaters of a tributary that occurs in McHenry County, IL. Drilling, geophysical surveys, and the analysis of existing geologic and water well data were used to determine the lithologic and geometric Cited by: 6.
