3D Geologic Modeling Data

In two field seasons (2008-2009), the ISGS and McHenry County collected 31 continuous lithologic cores to bedrock (17 wireline-mud rotary, 14 rotosonic), which included downhole geophysical logs at each location (gamma ray and electrical resistivity). The ISGS also collected approximately 90 km of 2D geophysical profiles (seismic (51 km) and electrical resistivity (39 km)). The geophysical datasets help geologists further decipher the character of glacial sediments below land surface. These field data have been the key datasets for regional and local geologic interpretation in the County.

Datasets- Illinois geospatial data clearinghouse

The Illinois Natural Resources Geospatial Data Clearinghouse (Illinois Clearinghouse) is an established node of the National Spatial Data Infrastructure Clearinghouse Network. Hosted by the Illinois State Geological Survey since July 1, 1997, the Illinois Clearinghouse has become the de facto starting point for the GIS and remote sensing user communities in Illinois.

Geological Records Unit

The Geological Records Unit (GRU) is the state repository for drilling records as mandated by statute. The collections include records for more than 500,000 oil and gas wells, water wells, engineering borings, and miscellaneous test holes drilled in Illinois. Many regions of the state lack abundant outcrops and road and stream cuts due to relatively flat topography. Drill hole records provide the most abundant data available for geologic interpretation. These data are useful for environmental assessment, mineral resource evaluation and groundwater resource evaluation and protection. GRU is the gateway to Illinois geology.

Geological Samples Database

The Illinois State Geological Survey (ISGS) manages one of the largest collections of geologic samples in the United States. The collections are housed in the Geological Samples Library (GSL), located in the Natural Resources Studies Annex on the campus of the University of Illinois at Urbana-Champaign. The Geological Samples Library is the legislatively mandated repository for drill-hole samples in Illinois (State Law 225 ILCS 730/2), including cores drilled for mineral exploration and geologic investigations.

Illinois water and related wells

Interactive Map of wells and related data of Illinois.The ISGS is an official repository for records of wells drilled in the state of Illinois in our Geoscience Information Stewardship Section. Paper records are archived for over 700,000 wells. Some of these records go back as far as the late 1800s. Water and related well data can be accessed for private water wells, engineering borings, and stratigraphic borings. Many of the paper records have been converted to digital and are searchable within the ILWATER Interactive Map.

Three-Dimensional (3-D) Geologic Modeling

The need for improved geologic information is ever increasing as environmental and land-use issues continue to grow, with particular relevance to water resources. In northeast Illinois, bedrock aquifers are under regional stress and Lake Michigan sources are nearly fully allocated. Thus, McHenry County has responded with proactive water-resources planning. In cooperation with the County, the ISGS is in the final stages of completing a county-wide 3-D geologic model of the glacial deposits, which include the shallow sand and gravel aquifers.

Water Well Database

Another primary data source that is often abundant in McHenry County is the historical water well record dataset. The quality of water well records is a common concern when using these data for geologic interpretation, and various approaches are used by geologists to assess the value of those records.
