"What is acid sulfate soil?

Acid sulfate soil or rock are soils, sediment or rock that contain elevated concentrations of iron sulfides (commonly iron pyrite) or the products of sulfide oxidation. Acid sulfate soil can be present in two forms:

• Potential acid sulfate soil contains iron sulfides that are stable in an un-oxidised state. If left undisturbed, these soils pose little threat of acidification
• Actual acid sulfate soil is material that has been exposed to oxygen, producing sulfuric acid.
  Acid sulfate soil can be disturbed by activities such as land excavation, tunnelling, blasting and drilling. It can also be disturbed by lowering the groundwater table. If managed inappropriately, once disturbed, waste acid sulfate soil may pose a risk to human health, buildings and structures, and the environment.

you would not want PASS dumped in your paddocks without it being treated properly - and even if it was treated properly - you still would not want it
