Beth, Here is an email chain and an attached report of sample results. Dan Bowen of IEPA gave the all clear on the sampling and the go-ahead to backfill the area that was excavated to remove the contaminated soil. Let me know if this is enough or if you need me to reach out to Dan and IEPA for something else.
