The source removal action to address source area contaminants at the MPA began in spring 2015 using a combination of the three different processes to achieve cleanup goals. Landfarming is a treatment technique that involves bringing contaminated soils or material to the surface, or into treatment cells, where it is frequently turned, or tilled, to allow aeration. This air is then used by aerobic microorganisms living in the soil, which allows them to flourish and subsequently use the trapped solvents as a source of food, effectively reducing the concentration of subsurface soil contaminants with minimal disturbance.

The biovent system pulls ambient air from the atmosphere and forces it underground via a series of pipes, wells and a large air compressor. This vacuum pulls air through the soil, which then allows underground solvents to be removed from the subsurface. The SVE applies a vacuum to soil via a series of pipes buried in the ground.

The Board of Commissioners voted 3-2 to make having a business license a requirement for the federal assistance administered.
These objectives are being met at the MPA by removing the source(s) of the contamination via excavation and landfarming of contaminated soils, and installing two different treatment technologies: a soil vapor extraction system (SVE), and a biovent system.

The area was used for various activities associated with the testing, manufacturing, overhauling, and storage of rocket engines, jet engines, and associated components.Īn excavation is conducted at the MPA former chemical storage area, which is being backfilled with remediated soil from the landfarm. One of the source areas that contributed to the contamination was the Manufacturing Plant Area (MPA), otherwise known as Operable Unit 4 (OU4).
Causes of the contamination (primarily trichloroethylene or TCE) have included placement of waste solvent into unlined lagoons, leaks of solvent from manmade structures, and use of the solvent for weed control. Numerous studies conducted since 1994 have indicated the presence of thousands of pounds of solvent-related compounds in multiple areas of the site. This Superfund site was discovered in July 1994 as a result of investigation into a citizen's complaint about gasoline contamination in a well located west of Highway 71 on Quince Road, southwest of the Neosho city limits. In response to public requests, EPA Region 7 has compiled this fact sheet to provide updated information on recent and continuing removal activity at the Pools Prairie Superfund Site’s Operable Unit 4 (OU4), Neosho, Mo.
