Rumpke Sanitary Landfill

[2] 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.

[1] The north face of the mound cracked and fell forward, exposing 15 acres (6.1 ha) of buried waste.

[1] Attorney General Betty Montgomery called the incident "the largest trash landslide in Ohio history".

[10][9] A 14-year-old circus elephant, the world's largest Hershey's bar and a Super Bowl ring are some of the items buried in the landfill.

[14] The plants can recover about 15 million cubic feet per day (420×10^3 m3/d) of landfill gas, making it the largest recovery operation of its kind in the world.

[10] Levels of hydrogen sulfide, volatile organic compounds, carbon monoxide, and methane are included in the measurements.
