SuRF ANZ - Sustainable Remediation Forum for Australia & NZ

Sustainable remediation is a rapidly developing research and environmental management topic within Australia and internationally. SuRF ANZ has been set up to help promote the use of sustainable practices within Australia and New Zealand, in terms of environmental, economic and social indicators, during the remediation and development of contaminated land. 

SuRF ANZ is committed to the development and promotion of sustainable remediation practices for application to contaminated land and groundwater projects. SuRF ANZ is an independent member of the International Sustainable Remediation Alliance (ISRA) proclaimed in 2016.


SuRF ANZ’s achievements include:

  • Ongoing development of a Framework for Sustainable Remediation;
  • Establishing SuRF ANZ policy in consultation with members;
  • Providing web based SR tools;
  • Organising meetings and forums for SR dialogues; 
  • Facilitating contact with international SR associations;
  • Contributing to a national remediation framework (NRF) currently being developed through CRC CARE.
