The Byron Salvage Yard site is in rural Ogle County, Illinois and is approximately 3 miles southwest of the city of Byron. During the 1960s the salvage yard owner accepted miscellaneous wastes and debris for disposal including drums of electroplating wastes, oil sludges, cutting wheels, solvents, and scrap metal. Industrial waste dumping reportedly occurred on the site during periods of heavy rainfall so that most of the waste would be carried offsite by the resulting surface water runoff. In 1976 the Illinois EPA documented the presence of cyanide and heavy metals in soil, surface water, and ground water in and around the site. In situ treatment of cyanide-contaminated soil less than 100 mg/kg was performed but low levels of cyanide still remain. Water quality sampling, performed in 1984, revealed that offsite ground water was contaminated wi th VOCs, primarily TCE. The two aquifers which underlie and surround the site contain elevated levels of VOCs, metals, and cyanide. The selecte remedial action for this site includes removing all wastes generated during the remedial investigation; adding a one-foot soil cover to the affected portions of the site and regrading and revegetating the new surface.
