Opposition is increasing against carbon capture projects in Illinois due to concerns over potential risks to the Mahomet Aquifer, a critical water source for nearly one million people across central Illinois. The aquifer provides water to more than 100 communities, businesses, and farmers, making it vital to the region’s economy.
A new Illinois law mandates that companies must offer alternative drinking water sources if carbon dioxide (CO2) injection or storage contaminates existing supplies. Pan Rickert of the Eco-Justice Collaborative highlighted concerns that no alternative water source is available for the Mahomet Aquifer if it becomes contaminated, potentially resulting in severe economic impacts.
A poll conducted by Rickert’s group revealed that 82% of Illinois registered voters oppose the use of eminent domain by private corporations for carbon dioxide pipeline and sequestration projects. Additionally, 89% expressed concerns about the risk of CO2 leaks.
The Illinois Prairie Rivers Network identified three proposed carbon capture projects involving CO2 injection near the aquifer. Recent incidents, such as a CO2 leak from a well in Decatur, have fueled calls for stricter regulations on carbon capture and storage projects.
