The widely-publicised soil and groundwater acidity and arsenic contamination problem which arose in the City of Stirling in late 2001 highlighted the potential environmental problems and infrastructure damage that can be caused by development that involves the disturbance of acid sulfate soils.

Given the seriousness of the issue, the WAPC has adopted the planning guidelines for acid sulfate soils set out in appendix 1 of the planning bulletin, and the WAPC information requirements for applications on land where there is a significant risk of disturbing acid sulfate soils set out in appendix 2 of the planning bulletin for the purpose of future decision-making.

The WAPC is developing a comprehensive policy response to the issue of acid sulfate soils. In the meantime, the planning guidelines set out in appendix 1 provide information and advice on relevant considerations to be taken into account in planning decision-making.

In addition, the Department of Environment and Conservation has prepared the acid sulfate soils guidelines series to assist agencies, developers and individuals to manage development in areas where acid sulfate soils may or will be impacted. Copies of documents in the acid sulfate soils guidelines series and further technical advice and information can be obtained from the acid sulfate soils in Western Australia page on the Department of Environment and Conservation's website.
