Lawmakers Probe Illinois Water Use Amid Drought And Data Centers

Illinois lawmakers are actively probing the state's water usage and reporting mechanisms this spring, spurred by persistent drought conditions, local water emergencies, and the growing demand from data centers. Non-voting subject-matter hearings have been convened to gather expert testimony from researchers, regional planners, and municipal leaders who warn of significant gaps in groundwater data and insufficient reporting rules, hindering long-term water planning. Witnesses, including Jenna Shelton from the Illinois State Water Survey and Zhenxing "Jason" Zhang, emphasized the need for more frequent and compliant reporting on water use, noting that current rules for wells pumping 70 gallons per minute or more are poorly enforced. Staffing shortages within the Illinois Department of Natural Resources also impede monitoring. Hyperscale data centers have emerged as a focal point due to their substantial water requirements for cooling, pushing the issue into the legislative spotlight. Proposed legislation, such as the POWER Act, aims to increase transparency by requiring large data centers to disclose water usage, obtain permits from the Illinois Environmental Protection Agency, and meet specific efficiency and wastewater standards. While proponents advocate for basic transparency, industry groups and some local officials express concerns that stricter regulations could deter data center investment in communities. As summer approaches, communities reliant on groundwater supplies are awaiting legislative signals, with scientists advocating for improved data, clearer regulations, and increased staff capacity to prevent future water crises.
