Hierarchy of managing acid sulphate soils
1. minimise disturbance -
pick another site
or minimise excavation.
Mitigation :
2. prevent oxidisation - place ASS into an
anaerobic environment below
watertable.
3. treat to reduce acidity - mix with excess
agricultural lime (pH 8.2), a slow
process
Environment Protection Act approved
Remediation :
4. re-use : after hastened oxidation
5. dispose : managed dump sites
