Downers Grove Groundwater Investigation
During the spring of 2001, the Illinois EPA began a groundwater investigation just east of I-355 near Downers Grove. This investigation is in response to citizen concerns related to recent private well sampling in neighboring Lisle. Results of a few samples in Downers Grove in May showed some solvent contamination in scattered wells. Consequently, Illinois EPA decided to initiate a separate investigation in Downers Grove to identify contaminated wells and potential sources. The area map referenced in the fact sheet will be included in a separate pdf attachment.
