Downers Grove Groundwater Investigation
Downers Grove, Illinois
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 Illinois EPA collected samples from private water wells in unincorporated
Downers Grove during the week of July 16, 2001. The results from theses
samples constitute the first phase of the Downers Grove Groundwater Investigation.
In this first round of sampling, approximately 160 wells, in three areas
were analyzed for levels of solvent-type chemicals, known as volatile
organic chemicals (VOCs).
