Increased Water Demand Threatens Deep Bedrock Aquifer Water Supplies
•October 14, 2015• Deep sandstone aquifers that feed water supplies to parts of northeastern Illinois are at risk of becoming partially or completely depleted in the next 35 years, a new study at the Illinois State Water Survey (ISWS) suggests. Daniel Abrams, a groundwater flow modeler at the ISWS, University of Illinois, and colleagues conducted the largest measurement of deep sandstone groundwater levels in 34 years. Water levels in 576 wells were measured in 33 counties between July 2014 and February 2015. In northeastern Illinois, the sandstone aquifers are hundreds of feet deep, meaning that water pumped from the aquifer … Read More
