Data of the risk of Potential Acid Sulfate Soil (PASS) materials being disturbed by land development activities based on the likelihood of PASS materials occurring within 3m of the ground surface for the Lower South West Region. This data is designed for use by planners to assess whether development applications for specific sites require additional conditions on the basis of whether normal land development activities carry a risk of disturbing PASS materials. Disturbance risk is rated on the basis of the likelihood of PASS materials being encountered within 3m of the ground surface should this depth of soil be disturbed in any way. The depth of 3m is considered since this was regarded as the depth that most soil disturbance activities would extend during in most land development processes. Disturbance activities in this context include drainage, excavations and dewatering. For further information phone the Contaminated Sites hotline 1300 762 982. This dataset was formerly known as Acid Sulfate Soil Risk Map, Lower South West (DER-010). This dataset is no longer actively maintained by DWER.
