Remedial processes for contaminated land - principles and practice

This book provides guidance for good practice in the selection, design, commissioning, operation, monitoring and validation of process technologies for the remedial treatment of contaminated land. It stems from a CIRIA research project that examined the use of these technologies in the UK and, through an international review of experience and consultation with practitioners, established guidelines for good practice in these relatively new methods. Initial chapters describe the method and the general findings of the research. Nine generic technologies - those with some history of use in UK - are described using a consistent set of headings. The technologies are ex-situ bioremediation, enhanced in-situ bioremediation, natural attenuation, soil vapour extraction, air sparging, bioventing, dual-phase vapour extraction, soil washing and cement fixation. The final chapter uses the same headings to show what is needed in the research and development of a new treatment technology. Appendices provide additional information on specification of the technologies. The text is supported by a comprehensive set of references. The book will be of interest to geotechnical engineers, environmental professionals, reclamation specialists, developers, regulators, planners and civil engineers.
