The proposed program will investigate the long term contaminant migration performance of different microbial and organic contaminants through engineered barrier systems. The main application of this work will be in the pre-design stage assessment of appropriate barrier systems for contaminated sites or containment facilities in terms of quantitative comparisons with other potential technologies. The knowledge gained from the research will also provide information which could lead to more cost effective, yet equally reliable engineered barrier systems for lagoons, landfills, contaminated sites, etc. The research program is subdivided into two main themes: 1) microbial transport through GCLs, and, 2) organic contaminant transport through soil cement mixtures containing coal fly ash. A literature review of these theme areas found a paucity of information currently exists.

该项目将研究不同微生物和有机污染物通过工程屏障系统的长期污染物迁移性能。这项工作的主要应用将是在设计前阶段评估受污染场地或封闭设施的适当屏障系统，与其他潜在技术进行定量比较。从研究中获得的知识也将提供信息，这可能会导致更具成本效益，但同样可靠的工程屏障系统泻湖，垃圾填埋场，污染场地等的研究计划分为两个主要主题：1）微生物运输通过GCL，和，2）有机污染物运输通过土壤水泥混合物含有粉煤灰。对这些主题领域的文献回顾发现，目前存在的信息很少。
