Natural Attenuation of Contaminants in Soils

Natural attenuation has become widely recognized as an effective and low-cost alternative to more expensive engineered remediation. However, there are uncertainties about natural attenuation?s long-term effects and risks to the environment. There is a particular need to develop a high level of understanding of the natural attenuation processes in order to enable its proper implementation. Natural Attenuation of Contaminants in Soils covers this natural process and its proper implementation. It examines the theoretical processes, case studies, protocols, numerical models, and legal aspects in the natural attenuation of organic and inorganic contaminants. The book provides information for evaluation of natural attenuation as a design tool for construction of land-based waste disposal, and as a management control mechanism for leachate plumes. It also provides information for an in situ procedure for structuring remediation options.
