Acid Sulfate Soils

Do you have Acid Sulfate Soils on your site? Airsafe offers solutions including Acid Sulfate Soil Assessment Reports and Acid Sulfate Soil Management Plans tailored to your situation.

Acid Sulfate Soil Assessment is frequently performed as part of a Contaminated Land Assessment for the Development Application process or to dispose of soil.

Acid Sulfate Soil Assessment Reports and Acid Sulfate Soil Management Plans are available from Airsafe and are complying with NSW EPA and Council regulations.

Acid sulphate soils are soils and sediments that naturally contain iron sulphides.

When they come into contact with oxygen, they form sulfuric acid, which can damage building structures and pollute the environment.

Acid sulphate soils can corrode concrete and steel, disrupt plant development, and harm waterways, to mention a few of the key difficulties.

In NSW, acid sulphate soils have been discovered in every coastal estuary and embayment.

Acid sulphate soils are classified into two types:

Potential Acid Sulfate Soils:

Potential Acid Sulfate Soils (PASS) are soils containing sulfidic ores that have not yet reacted after coming into contact with oxygen.

PASS has a pH that is normally higher than pH4 and can be neutral or slightly alkaline at times.

Waterlogged soils and unripe muds, as well as sands and silty sands linked with watercourses, are among the general soil compositions influenced by PASS.

Actual Acid Sulfate Soils:

Actual Acid Sulfate Soils (AASS) are soils in which sulfuric acid has been produced by the reaction of sulfidic ores with oxygen.

A pH reading of less than 4, a sulfuric (rotten egg) odour, or the presence of yellow mottles and jarosite coatings are all common AASS features.

How can Airsafe Help you ?

Airsafe has conducted acid sulphate soil assessments in the past, including concrete and steel abrasion, waste management, and residential development applications.

Our services include consultation, site investigation, and sample recovery by our team of contaminated lands experts with a thorough understanding of sampling methodologies and trends.

The recovered samples are transferred to a third-party laboratory, which adds to the assurance that the results are unbiased.

For all acid sulphate soil investigations, the investigation’s details, results analysis, and any suggestions are supplied as usual.

Airsafe can also create associated management plans in order to meet legislative, regulatory, or project needs.
