Site is located approximately 14 miles east of the town of Kankakee, IL, within Pembroke Twp.,
Kankakee County. Site consists of a 20-acre parcel of land. Cross Brothers operated a drum and
pail reclaiming operation at the site from 1961 until 1980. The operation employes a crude process
to incinerate the residue material contained in drums and pails received for reconditioning.
Essentially, the operation consisted of inverting the containers to allow the residue material to drain
out onto the ground. Then solvent would be added to the containers to dissolve any remaining
residue. Throughout the process, the operation was haphazard, allowing indiscriminant dumping of
great quantities of residues (largely dyes, pigments, inks, and solvents). PCB-contaminated soil
was excavated.
Wells are pumped to remove ground-water, and treatment occurs above-ground. Re-injection of
treated groundwater for flushing of source area vadose zone contamination occurs via a sprayfield,
with sprinklers, and for flushing the saturated portion of the aquifer, occurs though injection wells
downgradient of the source area. Extraction and injection wells are also utilized to maintain
hydraulic control at the downgradient edge of the contaminant plume. The source area is
approximately four to six acres in extent. areal extent. A confining clay layer is present at 45 to 50
feet below the ground surface, and the water table is variable with season, from four to eight feet
below the ground surface. There is not a slurry wall or other physical construct present at the site
acting as an engineered barrier. Injection and extraction wells immediately downgradient of the
source area, and injection and extraction wells immediately downgradient of the downgradient
(leading) edge of the contaminant plume are installed to a depth one foot above the confining clay
layer. The targeted unconfined aquifer consists of very well sorted, fine-grained sand. Standard
MCLs are the treatment goal.
