Resources - Acid sulfate soils
Terms frequently used in literature about acid sulfate soils
- Potential acid sulfate soils (PASS)
- soils or sediments that contain sulfides with the potential to oxidise and become severely acidic.
- Actual acid sulfate soils (AASS)
- soils or sediments that once contained sulfides but that have oxidised and become severely acidic.
- Monosulfidic black oozes (MBOs)/monosulfidic material
- lightweight, gel-like material that is highly chemically reactive. MBOs are often found in the bottom of permanently submerged wetlands, drains and waterways affected by salinity.
- Sulfidic material
- similar meaning to PASS but a more precise definition of soil containing detectable levels of sulfide minerals.
- Sulfuric material
- similar meaning to AASS but a more precise definition of material with a pH of 4 or lower due to sulfide oxidation.
- an iron sulfide mineral that is a common component of sulfidic material.

Agencies responsible for information and direction on acid sulfate soils
National Committee for Acid Sulfate Soils
The National Committee for Acid Sulfate Soils (NatCASS) is one of the mechanisms by which the Australian, state and territory governments, research institutions and industry are working together to address acid sulfate soil issues.
NatCASS meets twice a year to share information and to work on implementing the National Strategy for the Management of Acid Sulfate Soils.
