Our liner is a crucial element of the total landfill
 design process and ensures the absolute upmost in environmental 
protection.

The purpose of any liner is to prevent 
migration of leachate from the site. Leachate is 
the result of water that has percolated through the 
waste and is a potential pollutant if it is not
 managed correctly.

We  make absolutely sure our liner is designed and installed with materials that have minimum permeability. We also have to be very aware of  proper
 compaction processes, moisture content, and in
situ densities. As recognized by environmental experts and regulatory agencies, recompacted impermeable clay liners provide protection against leachate migration.

To certify that the liner design is constructed precisely to plan, AEL implements a quality control and assurance program. Independent professional engineers monitor the construction steps, and perform quality assurance testing at key points of the project.

So you see, we go to great lengths to provide the needed safety for our workers and the public. AEL will only commence operation of a sanitary landfill after all quality assurance testing is completed and the landfill has been approved by ODEQ.
