EPA begins Five Year Review
The EPA will be inspecting the environmental cleanup at the Midway Landfill Superfund Site as part of the site’s third five-year review. Five-year reviews are site evaluations done to make sure the cleanup measures completed for the site continue to be protective of human health and the environment.
Cleanup actions and measures were done between September 1985 and January 1992, including:
- Installing an active gas control system. Extraction wells remove gas and route the underground gas to a blower/flare system.
- Re-grading the landfill surface, increasing soil cover and improving surface water runoff.
- Covering the landfill with multiple layers to seal in contamination (referred to as capping).
- Constructing a detention pond, including a permanent dewatering system.
- Blocking the culvert that drained water from Linda Heights Park directly into the landfill. Surface and storm water rerouted by a pipeline and pump station to the detention pond.
- Land use restrictions determined and recorded. New or potential property owners informed that the property is a landfill. Water in the vicinity cannot be used for drinking water nor domestic wells constructed. Residents are already on the city water system and are not at risk.

The Midway Landfill is a 60 acre former gravel quarry that operated as a muncipal solid waste landfill from 1966 to 1983. About 3 million cubic yards of waste were deposited in the unlined landfill. The Midway Landfill was created primarily to accept demolition materials, wood waste, and other slowly decomposing materials, but other industrial wastes were also put in the landfill, including paint sludges, oily waste water and sludges, alkaline waste, and coolant. In 1983, the landfill was covered with silt and fine sands. In l985, combustible gas was detected in structures around the landfill. Contaminated groundwater was also found beyond the landfill boundary. Approximately 8,200 people live near the affected area. Two elementary schools and a community village are located within ½ mile of the site.
