Ravi’s work focuses on the remediation of contaminated soil, water and air, and the potential impacts of contaminants upon environmental and human health at local, national and global levels. For more than two decades, Ravi has been a global leader in the move to the now widely accepted ‘risk based’ approach to managing contaminated sites. He has also been a leader in the shift to in-situ remediation – cleaning up contamination where it lies, rather than the traditional ‘dig and dump’ approach. Together, these approaches potentially save industry millions, if not billions, of dollars annually and make clean-up far more feasible and effective.
