Rumpke Sanitary Landfill

Rumpke Sanitary Landfill, more colloquially known as Mount Rumpke or Rumpke Mountain, is one of the largest landfills in the United States located in Colerain Township, Hamilton County, north of Cincinnati, Ohio. It is owned by Rumpke Consolidated Companies, Inc. and occupies over 230 acres (93 ha) of a 440-acre (180 ha) tract of land that the company owns. The landfill receives 2 million tons (2×109 kg) of household and industrial wastes annually.

Mount Rumpke is 1,075 feet (328 m) above sea level and the highest landform in Hamilton County, Ohio, clearly visible from U.S. Route 27. It is the largest landfill in the state of Ohio and the sixth largest in the United States. It is sometimes claimed that it is the highest point in Ohio, but in fact there are higher elevations in many Ohio counties.
