In the second half of the twentieth century, increasing efforts were made towards containing and cleaning contaminated groundwater. A number of techniques can be used to achieve such goals, traditionally either by treating or isolating the soil in situ, or by removing it for washing or disposal. However, such technologies tend to be accompanied by high energy consumption, and can lead to new environmental problems. Therefore, more efficient and economical techniques are needed to remediate contaminated soil and groundwater.
Advanced Groundwater Remediation contains a selection of the most up-to-date research results on reactive barrier and pump-and-treat techniques, with the main focus on heavy metal removal. After dealing with general issues of groundwater remediation using active and passive processes, remediation engineering practice is discussed, with the emphasis on chromium remediation, innovative applications, engineering design and performance monitoring. There is particular focus on sorptive removal and on natural processes, including metals loading on sorbents, sorption mechanisms, monitored natural attenuation and phytoextraction.
This book will contribute to improving groundwater quality: firstly, through enhanced efficiencies in research investment, by avoiding needless overlap/competition between approaches; secondly, by achieving a clearer recognition of situations for which a particular approach is best suited, and of the specialist capabilities essential to the informed delivery of each; and finally, by achieving recognition for the value and maturity of the whole field of groundwater remediation.
