 Cutoff Walls (CO5) 

The vertical Cutoff Walls on the Coke Ovens site are intended to work in conjunction with other design elements of the overall remedial approach, including the Coke Ovens Surface Cap, the Coke Ovens interceptor line, and a water treatment plant.

The cutoff walls will serve to control the movement of clean and contaminated groundwater over the coke ovens site.

Two cutoff walls have been designed; one across the north side of the coke ovens site and one on the south and west sides. the walls are made up of a combination of bentonite slurry (mud-like material) and low permeability soil for areas of changing topography or shallow excavation.
