Authoritative field study of groundwater resources and subsurface materials
This report compiles borehole data from a regional water resources study in northeastern Illinois, including methods, locations, and sample results. It offers a clear view of how geologists collect and interpret subsurface materials in a metropolitan setting.
- Learn how holes were drilled, how samples were collected, and how the data were tested in the field and lab
- See how locations are mapped and described, with coordinates and map references for each boring
- Explore the grain-size analyses and test terms used to describe density and consistency of soils and sediments
- Understand how stratigraphy is interpreted and how the data are organized for future study
Ideal for readers with an interest in geology, hydrology, and how large-scale subsurface investigations are documented and shared.
