The Southside Sanitary Landfill site occupies 312 acres in Indianapolis, Indiana. The landfill is an active solid waste disposal facility that began operating in 1971. An estimated four million cubic yards of waste, including coal tar, asbestos, iron oxide and clarifier sludges, and paint waste, were buried at the landfill, leading to soil and groundwater contamination. Following cleanup, groundwater monitoring is ongoing. EPA took the site off the Superfund program�s National Priorities List (NPL) in 1997.
