    Description

    Professor Paul Nathanail FGS CGeol SiLC, University of Nottingham & Land Quality Management Ltd Risk based contaminated land management involves gathering information about sources, pathways and receptors and then assessing that information to discern whether remediation is needed, in a specific legal context. Type 1 errors (wrongly remediating land) should be minimised while type 2 errors (not remediating high risk land) must be minimised. This means that conservative generic assessment criteria should be used to filter contaminants out from further consideration rather than to determine that remediation is needed, let alone to establish what remediation should achieve. As such, a clear appreciation of the intended use of specific assessment criteria, the toxicological basis they are based on and the extent to which their exposure scenario fits with the situation at the actual site are needed. Once remediation is deemed necessary, then recent innovation can help to ensure that the most sustainable strategy is adopted. The presentation will include details of recent research and case studies in both risk assessment and sustainable remediation. Paul Nathanail is one of the UK’s leading specialists in the assessment and remediation of contaminated land. He combines research and consultancy with being course director of Nottingham's unique Environmental Geoscience BSc, the Environmental Management MSc and long running post graduate vocational courses in contaminated land management.
