Subsurface Restoration

Presenting a clear, understandable examination, this book outlines efficient, effective methods and strategies for the complex field of subsurface remediation. The editors fully assess the state-of-knowledge of subsurface science requisite for finding new solutions, providing a focused guide for advanced subsurface remediation technology. Unparalleled in scope and practicality, Subsurface Restoration assists those persons determining the extent of environmental contamination for remedial technology selection and for environmental decision-making at all levels.

This is a scientific view of what toxic chemicals threaten our environment and our bodies, what risks are exaggerated, and what is being downplayed in the media (as revealed, for example, in A Civil Action).

This valuable resource discusses several strategies of manipulating colloids for environmental restoration, identifies advantages and disadvantages of each strategy, and considers obstacles limiting the application of each strategy. Approaches evaluated include the following: Chemical modification of subsurface systems to mobilize or deposit colloids in situ Altering the mobility of microorganisms to improve delivery of microbes for bioremediation Manipulating colloids or biocolloids (bacteria) to change aquifer permeability to either enhance bioremediation or create in situ barriers Introducing modified colloids, surfactants, and emulsions to control colloid mobility or to increase recovery of sorbed contaminants by pump and treat methods Manipulation of Groundwater Colloids for Environmental Restoration also contains short, focused research reports on specific studies relevant to the various approaches under consideration. Subjects covered range from mobility of organic macromolecules by controlled field injection experiments to new techniques that investigate surface chemistry and aggregation of inorganic colloids. Other topics discussed include the depositional behavior and transport of biocolloids in porous media, surfactants as modifiers of surface binding sites on colloids, and genetic engineering of microorganisms to serve as contaminant-scavenging biocolloids. Manipulation of Groundwater Colloids for Environmental Restoration is an excellent resource for research scientists in hydrology, chemistry, and microbiology; environmental consultants; regulators; environmental engineers; bioremediation microbiologists; and engineers.

"This unique, single-source reference offers a thorough treatment of the remediation of soils contaminated by hazardous wastes and the scientific and engineering issues that must be addressed in creating practical solutions for their reclamation."

Environmental Contamination and Remediation Practices at Former and Present Military Bases outlines the different strategies that are useful in the investigation and subsequent remediation of military bases, Particular attention is paid to the pollution of groundwater. The book contains an excellent review of useful remediation techniques and several examples of their application to polluted military bases. Several mathematical models are demonstrated, showing their predictive value for real examples. A detailed list is given of chemical pollutants that can be found on a military base. Strategies are described for the investigation and determination of the future of a polluted military site. Examples are given, obtained from practical experience of dealing with old, contaminated sites.
