This volume 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 a review of useful remediation techniques and 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.
