Abstract:

The purpose of this landfill-closure evaluation project is to assist the Environmental Security Technology Certification Program ESTCP and their United States US Department of Defense DoD technology-transition partners in developing alternative landfill closure designs and management strategies that can enhance the long-term natural attenuation of chlorinated aliphatic hydrocarbons CAHs i.e., chlorinated solvents in landfills and landfill-leachate-contaminated groundwater. The project was divided into three primary tasks Task 1 - Literature ReviewLandfill Data Review. This task involved completion of a literature review that focused on determining how alternative landfill closure designs and landfill management strategies can impact the natural attenuation of and long-term risk associated with CAH groundwater plumes. Task 2 - Conceptual Landfill-Design Model. This task involved preparation of simple decision-logic diagrams Initial Landfill Screening, Remedial Alternatives Evaluation, and Cover Type Selection and several design alternatives that could be used to optimize CAH biodegradation while minimizing plume migration. Task 3 - Final Technical Report. This technical report describes the decision logic diagrams and is intended to provide DoD engineers with a useful tool for evaluating the potential for enhancing CAH biodegradation at landfills undergoing final closure planning and design.
