Acid Sulfate Soils Remediation Guidelines for Coastal Floodplains in NSW

These guidelines have been developed to provide a framework for designing the most effective acid sulfate soil remediation projects for low-elevation floodplain sites such as broadacre agricultural land – particularly (former) freshwater backswamps and saline wetlands. 

The guidelines provide information for developing remediation strategies based on the physical characteristics of the floodplain landscape.
