Summary

The Aquifer Protection Act obligates any data center that wants to build or already operates in Illinois to create a detailed water‑resources plan, submit it for state review, and publicly report its water use. It also bars data centers from pumping water from the Mahomet Aquifer when the state determines such use would cause an adverse impact. The bill aims to protect drinking‑water supplies, agriculture, and ecosystems by making water consumption transparent and accountable.
