In Situ Remediation Engineering provides a detailed examination of all modes of in situ reactive zone deployment: chemical and biological, reducing and oxidizing, inorganic and organic, stabilization and destruction. Throughout the text, pertinent physical, chemical, biochemical, microbial, and hydrogeologic principles are introduced to support the reader's understanding of the material. Separate chapters are devoted to desorption processes, selection of a reactive strategy and delivery and distribution systems. Also included are selected case studies as well as supporting evidence and conclusions synthesized from the authors' involvement in hundreds of projects.
