As temperatures rise and climate change becomes an increasingly important issue, geologic carbon dioxide (CO2) sequestration is a viable solution for reducing greenhouse gas emissions. Subsurface 3-D modeling and groundwater flow modeling were completed as a component of a CO2 sequestration feasibility study in the city of Decatur, Illinois. The Decatur Archer Daniels Midland Company Ethanol Plant (ADM) serves as the injection site for a CO2 sequestration project within a deep saline reservoir.

The 3-D geologic model shows the Peoria Silt, Wedron Formation, and Cahokia Formation at the surface with the Wedron Formation holding up the steep slopes along the east and west banks of Lake Decatur. The groundwater flow model outlined the location of a local groundwater divide and showed flow from the injection site would flow towards Lake Decatur, reaching the lake in 80 days.
