Site Location: US EPA Region 5 Greenville Landfill, Greenville, Ohio

Project Status: Completed in January 2008

Setting / Purpose: Freshwater Creek – Eroding Closed Landfill Cap.

Contaminant(s) of Concern: Creek bed erosion penetrated historic landfill cap and was causing a release of leachate from landfill into creek. Ohio EPA approved design that incorporated AquaBlok as primary low permeability seal for re-establishment of certified landfill cap.

AquaBlok Cap Design / Site Area: A multi-layer design was used to first re-establish the landfill cap, then to provide protection to high flow conditions in the creek bed. The first layer utilized a 6” thick geocell material to maintain the AquaBlok capping material on the slope of the creek. This was then covered in a geofabric and a layer of stone, before an articulated concrete mat was placed over the entire area, to provide the final level of protection from long-term erosion to the bank. Site area was comprised of 3,000 square feet of embankment area.

Method of AquaBlok Placement: Land-based excavator.
