The 65-acre site is comprised of the ground water and five areas: the South Landfill; the North Landfill; the Liquid Disposal Area; the Ash Disposal Pit; the Ash Pile. The landfills and an incinerator opened in 1968 to process and dispose of municipal and industrial wastes. The wastes were burned or landfilled on site. Liquid wastes including oils and solvents were dumped and buried on site. A contaminated underground area, or plume, of organic chemicals flowed from the liquid disposal area into the nearby Great Miami River. This plume contaminated many residential wells.
The site was cleaned up in the mid-1990s. The Ash Disposal pit was covered with a water-resistant cap. The Ash Pile was moved to the South Landfill and capped. The North Landfill and Liquid Disposal areas were also capped. Soil vapor extraction and ground water pump and treat systems were installed in the Liquid Disposal area. Between 4 and 6 million gallons of contaminated ground water are being removed and sent to the Troy Treatment Plant. The SVE system successfully removed the organic chemicals and was shut down in 2000. Ground-water treatment is expected to continue at least 10 more years.

EPA completed a review of the landfill's cleanup. This type of review is required at least every five years where the cleanup is complete but hazardous waste remains managed on-site. These reviews are done to ensure that the cleanup continues to protect people and the environment.
The review included:
- An evaluation of background information
- Cleanup requirements
- Effectiveness of the cleanup and any anticipated future actions
- Maintenance and monitoring efforts
- An analysis of ways for EPA to operate more efficiently
The review found that the cleanup continues to protect people and the environment. The next scheduled review will be in 2015.
