CHAMPAIGN – State Senator Paul Faraci has introduced legislation to prohibit carbon capture and sequestration activities over, under or through the Mahomet Aquifer – a vital sole-source aquifer supplying clean drinking water to over 500,000 residents across 14 counties in East Central Illinois.

“The Mahomet Aquifer is a lifeline for many residents, and while carbon sequestration can play a role in addressing climate change, we need to ensure it doesn’t put our community’s water at risk,” said Faraci (D-Champaign). “This measure is about exercising caution to protect the health and safety of our residents and safeguarding this crucial resource for our future generations.”

The Mahomet Aquifer is not only a source of drinking water, but it also supports agricultural and industrial industries in the region. While federal protections exist for groundwater, concerns remain about the long-term safety of underground storage near the aquifer. In the event of a leak, carbonic acid could react with other minerals in the rock formations, releasing new elements into the water. Recent assessments from the Illinois Geological Survey underscore the vulnerability of the aquifer, warning that these activities would need to be closely monitored to prevent environmental damage.

Faraci’s measure builds on ongoing efforts to elevate the protection of the Mahomet Aquifer as a priority in state policy, ensuring sustainable practices are enforced and harmful activities are prevented. This is crucial for residents of Central Illinois, as the aquifer is the only source of clean drinking water for at least half of the population it serves – meaning those residents would have no alternative should the aquifer become contaminated.

“While Illinois is on track to be a leader in carbon capture technologies, we must balance innovation with our duty to protect essential resources like the Mahomet Aquifer from any unintended consequences,” said Faraci.

Senate Bill 3968 awaits discussion in the legislative session.
