The Economics of Groundwater Remediation and Protection introduces economics and cost-benefit analysis as fundamental tools in remedial decision-making for contaminated aquifers, and in developing optimal protection strategies for groundwater resources. The authors provide a thorough introduction of the concepts of groundwater flow and contaminant transport, and illustrations of the types of risks and impacts caused. The text contains a detailed step-by-step methodology for remedial decision-making, allowing readers to work towards optimal remedial objectives and selection of least-cost alternatives. The authors use real world examples from their personal experience to illustrate the methodologies and put the issues into perspective.
