Since the first edition, there has been a multitude of legislation on the environment and the adoption of many of the principles of the European Landfill Directive. This has meant specialists, regulators and engineers are grappling with interpretation of guidance frameworks, new levels of testing accuracy and increased public perception of environmental damage. This new edition provides an up-to-date overview of the main principles and important aspects of a complex subject.
The first part of the guide sets the use of the investigation methods within a risk management context and highlights those aspects where different techniques or a different emphasis is needed to ensure that contamination is adequately addressed. The guide describes risk assessment as a means of evaluating the significance of any contamination identified, and looks at the development of the Conceptual Site Model as part of the assessment process.
The second part of the guide outlines the methods for setting targets for remediation, and explains the overall selection process needed to determine the most appropriate remediation strategy. Alongside the traditional civil engineering techniques used for remediation in the last twelve years, this guide lays out the new innovative solutions to achieving cost effective and technically sufficient investigation, assessment and remediation today.
