Acid Sulfate Soil Removal in Newcastle NSW: What Developers & Councils Need to Know

If you're planning a development, excavation, or civil works project in coastal NSW, there's one environmental risk you can't afford to overlook: acid sulfate soils (ASS). Found throughout Newcastle, Lake Macquarie, and the broader Hunter region, these soils can threaten both your project and the surrounding environment if not properly managed.

Why Acid Sulfate Soils Matter

When exposed to air through digging or drainage, acid sulfate soils can produce sulfuric acid and leach heavy metals into the surrounding soil and water. The consequences?

• Corrosion of concrete and steel infrastructure

• Contamination of waterways and ecosystems

• Serious project delays if left untreated

Because of these risks, acid sulfate soil assessment and removal is often required as part of your DA process — particularly in low-lying, estuarine, or reclaimed areas.

Who Needs Acid Sulfate Soil Assessment or Removal?

If you're involved in:

• Residential subdivisions or infill development

• Council infrastructure projects or roadworks

• Coastal or waterfront building

• Civil or utility upgrades

…then a professional acid sulfate soil management plan may be legally required.
