Building on the success of bioremediation and phytoremediation technologies, Natural and Enhanced Remediation Systems explores remediation techniques that use the beneficial effects provided by Mother Nature. Written by a leader in the industry, the book provides state-of-the-art information on natural and enhanced remediation techniques such as monitored natural attenuation, in situ reactive zones, bio-augmentation, in situ chemical oxidation, phytoremediation, constructed wetlands, and engineered phyto-covers. It contrasts the new paradigms in remediation with the conventional remedies of the past two decades. It addresses theoretical and design aspects and includes case studies that illustrate implementation and performance details. The appendixes contain substantial information and data usually found scattered in many different books and research papers, making Natural and Enhanced Remediation Systems a comprehensive resource on cutting-edge remediation technologies.
