Abstract:

Remedial action to curtail leachate seepage on a sanitary landfill located in a subtropical climate included the attachment of new PVC liner to an existing 20 mil PVC liner which has been buried for two and one-half years and exposed to leachate. The existing liner was an integral part of a leachate containment system which utilized leachate recirculation for treatment. Concerns were: (1) Whether the new liner could be attached (seamed) adequately to provide a completely waterproof joint, and (2) Whether the existing liner had maintained its integrity so that it would continue to provide adequate leachate containment. A description is given of the tests performed and their results. (Edited author abstract. )
