The 19-acre Columbus Old Municipal Landfill #1 site is located in Columbus, Indiana. An unpermitted landfill operated on site from 1938 to 1966. It reportedly accepted municipal and industrial wastes, including solvents, acids, bases, paints and heavy metals. Landfill operations led to soil and groundwater contamination. Following cleanup, EPA is planning to take the site off the Superfund program�s National Priorities List (NPL).
