This book provides a comprehensive overview of innovative remediation techniques and strategies for soils contaminated by heavy metals or organic compounds (e.g. petroleum hydrocarbons, NAPLs and chlorinated organic compounds). It discusses various novel chemical remediation approaches (in-situ and ex-situ) used alone and in combination with physical and/or thermal treatment. Further, it addresses the recovery of NAPLs, reuse of leaching solutions, and in-situ chemical reduction and oxidation, and explores the chemical enhancement of physical NAPLs recovery from both practical and theoretical perspectives. Also presenting the state-of-the-art in waste-assisted bioremediation to improve soil quality and the remediation of petroleum hydrocarbons, the book is a valuable resource for students, researchers and R&D professionals in industry engaged in the treatment of contaminated soils.

StéfanColombano (PhD in Environmental Science and Technology) is research scientist and expert at the French Geological Survey (Orléans, France). He has over 12 years of in situ remediation experience in consulting & engineering companies. He was in charge of the development and application of remediation technologies for contaminated soils and groundwater. Since he joined the French Geological Survey, his main research interests are in the area of soil and groundwater remediation, with special focus on: i) recovery of NAPL (multiphase flow experiments and modeling), ii) design and optimization of in situ remediation systems. Within these research areas, he published more than 15 papers in scientific journals with peer review. He is also in charge of carrying out technical expertises on behalf of the French Ministry of the Environment on topics related to remediation implementation.

David Huguenot(PhD in Biology) is associate Professor in Biogeochemistry at Université Paris-Est (Champs-sur-Marne, France). His main research interests are in the field of soil remediation connected with an ecological engineering approach:

(i) biological processes involved in the treatment of soils and waters polluted by organic (pesticides, hydrocarbons, chlorinated solvents...) and metallic contaminants;

(ii) improvement of soil/plant relation to enhance remediation (biostimulation/bioaugmentation)

(iii)physico-chemical remediation of soils and waters (soil washing, advanced oxidation processes) combined with bio/phytoremediation. Within these research areas, he published more than 40 papers in scientific journals with peer review.

Yoan Pechaud (PhD in Process Engineering) is associate Professor in biological and chemical process engineering at Université Paris-Est Est (Champs-sur-Marne, France). His main research interests are in the area of biological processes for wastewater treatments and soil remediation. His current activity is organized around the biological and chemical transformations and transfer phenomena occurring in these processes. He combines experiments at different scales and modelling using conventional approaches used in process engineering. Within these research areas, he published more than 20 papers in scientific journals with peer review and is co-author of 3 book chapters.
