In the past, the assessment and management of groundwater contamination has been driven by contaminant concentrations. However, concentration data alone are sometimes not sufficient to fully understand the behaviour or effect of a plume over time.
Landowners who receive a clean-up notice should review it for both liability and the remedial actions required.
Can a landowner be required to clean up legacy contamination? A recent decision of the Queensland Planning and Environment Court provides essential lessons to demonstrate why this may not always be the case.
Since the 1970s, legislation and regulations have been progressively developed and more stringently implemented in Australia to protect human health and the environment from the adverse effects of land and water contamination. Little research on the consequences of these actions and the extent of the impact on remediation efforts exists in Australia.
CRC CARE is developing a National Remediation Framework (NRF) for remediating and managing contaminated sites. The NRF is designed to harmonise guidance and best practice in the remediation and management of contaminated sites in Australia, and builds on existing best practice and regulation.
