MM H mu n.if cmd Idooltty by block numbtr) Leachate produced by buried waste often must be totally contained to pre- vent groundwater and surface water contamination. Landfill gases must be sim ilarly controlled to reduce the risk ot explosion or asphyxiation at nearby structures. Liners and covers used at Army sanitaty landfills can prevent the production and migration of landfill leachate as well as migration of gas out side refuse boundaries. 'Information is provided to help Army installations choose landfill liner and cover systems resistant to chemical attack from the leachate generated and compatible with the environment.

(Cont'd) -s -S'A liner and cover system must be designed with consideration of pollution regulations, environment, climate, and type of leachate produced. Federal regulations requiring the landfill to comply with the most stringent local air and water quality standards are sumriarized. The material used as a liner or cover must also be chosen based on the environment, climate, and chemical compatibility with the leachate. Both nat ural and synthetic materials are available and each type must be expected to react differently with the leachate produced at a given site. Natural mater ials include clays and soils-either local or transported from another loca tion. Synthetic membranes include various manmade polymers that are seamed at the fill site to form a giant pouch to contain the leachate. In a separate class are asphalts and admixed materials; these may be either sprayed onto landfill walls or applied as with highway construction. A liner and cover system may incl"de piping, additional gas controls, and adjacent lagoons for collection, treatment, or recycling. The system should have monitoring devices or sampling points, as the landfill's continued suc cess depends on careful control throughout the service life and after clo sure. Examples are cited of landfill sites actually using complete liner and cover systems. A' UNCT-ASSIFIED StCyNITY CLASSIFICATION OF THIS PAGenFAw Of ChimWI DO 074407 CONFTDFNTTAL
