Acid sulfate soils commonly occur in coastal and low–lying environments around Australia. Containing high levels of sulfide, iron and aluminium, if excavated and exposed to air, acid sulfate soils generate acid that can create significant impacts to human health, the environment and infrastructure.
To determine the presence of acid sulfate soils in a built environment, soil samples must be collected and analysed from the site. Based on this analysis, the potential risk of acid sulfate soil can be assessed. Several factors are considered, including soil pH, sulfide and sulfate concentrations, and other contaminants. If the risk is found to be significant, a management plan is created to address the issue. Possible measures may include soil stabilisation, drainage improvements, and revegetation.
EESI offered technical advice to the Victorian EPA in developing the 2012 Victorian Best Practice Guidelines for Assessing and Managing Coastal Acid Sulfate Soils. Our approach distinguishes us from competitors by focusing on the science of acid sulfate soil chemistry to ensure accurate soil management and risk assessment. Our soil scientists are accredited by the CPSS and possess extensive experience in investigating and characterising acid sulfate soils, as well as conducting in-house weathering trials to comprehend acid generation. We devise comprehensive management plans for sulfate soils, customised to your particular circumstances, safeguarding both environmental and commercial outcomes.
