![Page 6: THE CHALLENGES OF CONTAMINATION REMEDIATION DURING ... · Remediation Environmental Monitoring Occupational Hygiene Australia’s industrial past has left a legacy of contamination](https://reader033.vdocuments.us/reader033/viewer/2022042908/5f397445eb636f0805603495/html5/thumbnails/6.jpg)
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 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
