Blue Island, IL

EAT was contracted to perform the excavation of a six acre former MGP plant located in Blue Island, IL. The project involved the excavation, transportation and disposal of over 110,000 tons of MGP impacted soil. The entire 6-acre site was divided into 25′ X 25′ grids. Each grid was excavated and post excavation samples were taken. Oversight was by the Illinois EPA. Excavation depths ranged from a minimum of 3′ to up to 12′. EAT removed a tar separator and stabilized the contents of the separator, which was then shipped to a hazardous waste landfill. In addition, over 1,000 linear feet of 24″ iron piping was cleaned, removed and recycled. Three gasholders were removed as well as one 225,000-gallon AST. Multiple other vessels as well as hundreds of feet of smaller piping were cleaned and removed. Over 100,000 gallons of impacted water was collected and shipped offsite. 

EAT rerouted a stream and remediated the streambed, excavating to depths up to 8′ in the bed. Over 25,000 tons of backfill were imported and compacted. 

Over 6,000 truckloads of material were shipped out of and brought into the site, along a railroad siding over the course of 7 months.
