REMEDIATION IN AUSTRALIA
AUSTRALIAN REMEDIATION MARKET DRIVERS
The current Australian environmental services market is largely driven by:
• land redevelopment
• regulatory compliance
Community pressures help drive demand for quality remediation.
Emerging contaminants such as Per-and Polyfluoroalkyl Substances (PFAS) are causing national problem for Commonwealth agencies.
REMEDIATION TECHNOLOGIES AND SOLUTIONS
REMEDIATION APPROACHES
• Various strategies should be considered
• Generally the “do nothing” approach is considered the cheapest, however be aware of “consultant creep”
• “Dig and Dump” is quick but can be costly
• “Contain” can be more cost effective but could limit future development
• Treatment is generally costly but deals with the “legacy of contamination”
• “Bio” is inexpensive but can be unreliable
