Broad-scale risk maps for several coastal regions of WA are accessible via data.wa.gov.au which delivers land-based spatial information to public.
The maps show two risk categories:
- Class 1 - (red/pink) high to moderate risk of ASS occurring within 3m of natural soil surface.
- Class 2 - (orange) moderate to low risk of ASS occurring within 3m of natural soil surface but high to moderate risk of ASS beyond 3m of natural soil surface.
Note: Areas outside these two risk categories have not been assessed due to the absence of suitable geological and geochemical information, however, ASS materials may occur in these areas.
