OSTI ID:6376808

The Lake Sandy Jo site is located on the southeast side of the City of Gary in Lake County, Indiana. The site was a former 40-acre water-filled borrow pit that was used as a landfill between 1971 and 1980. Various wastes including construction and demolition debris, garage and industrial wastes, and drums are believed to be in the site. The area surrounding the site is primarily low-density residential property. The pit was filled with ground water and was used for a short time as a recreational lake. The primary contaminants of concern are PAHs, phthalates, and heavy metals, found mainly in soils. The remedial action includes installation of a soil cover over the landfill with drainage blanket to control surface seeps; extension of water mains to affected residents in Gary; onsite consolidation of contaminated sediments ground water and surface water/sediment monitoring; and deed restrictions on landfills property and institutional controls on aquifer use. The estimated capital cost is $4,747,000 with annual OandM costs of $63,000.
