Symposium Details

Change is a constant across many aspects of our world today, and the contaminated land management practice is no exception. Be events swift and unpredictable, or the slow-moving culmination of a century of industrialisation, impacts to ground conditions are inevitable.

The Sustainability Symposium will present several different perspectives on how we can manage contaminated land through risk analysis, and the challenges associated with responding in a fashion that doesn’t contribute to the risk profile. ‘Sustainability’ can be perceived as a frequently-used buzz word, but this symposium aims to put a tangible face to aligning our finite resources with long-term priorities.

Presentations will inform the delegate’s day-to-day assessment and management work, as well as share first-hand emergency preparedness and response lessons learnt from the recent catastrophic events faced by Auckland and its surrounding communities.
