This reports the findings of the project to validate the predictive acid sulfate soil (ASS) risk within the Perth metropolitan area.
Specific outcomes of the program included:
- evaluating the spatial extent of potential acid sulfate soil occurrence in the areas identified as being high to moderate risk
- determining the vulnerability of the Bassendean dunal system to acidification from increased urbanisation
- identifying the risk factors that cause soil and groundwater acidity
- enhancing the delivery of ASS risk maps using geographic information systems to display imagery of soil profiles and natural geochemical hazards.
