Acid sulfate soils in coastal areas

Acid sulfate soils contain iron sulfides. These soils are often found in low-lying coastal areas around Moreton Bay.

Disturbing or exposing soil containing iron sulfides to air produces sulfuric acid. This makes the soil toxic and may harm the environment, our health, and infrastructure.

Harmful effects of acid sulfate soils

Acid sulfate soils present a major challenge to coastal area development, management, and use. Disturbing the soil can have severe environmental, health and economic impacts. 

Environmental effects

These soils can contaminate the water and affect the ecology of wetlands. It can harm habitats and dependent ecosystems. 

Contaminated water can also cause fish kills. Fish that survive are more susceptible to fungal infections. These infections can lead to diseases such as red spot. This can negatively affect recreational and commercial fishing. 

Public health effects

Acid sulfate soils can cause contact dermatitis if it touches your skin. The dust can also cause eye irritation.

Economic impacts

The soil can corrode concrete and steel, such as pipes and bridges, reducing lifespan. Use acid-tolerant concrete and construction products when building in an area with acid sulfate soils.

Acid sulfate soils can also cause lower crop yields.
