Acid Sulfate Soil Assessment and Management

  • Quantitative and qualitative assessment of Acid Sulfate Soils (ASS) and Potential Acid Sulfate Soils (PASS);
  • Preparation of acid sulfate management plans;
  • ASS neutralisation assessments;
  • Design and implementation management of ASS treatment systems.

Acid Sulfate Soils (ASS) often occur in low-lying areas, predominantly below 5 m (AHD), in both coastal and inland areas. When left undisturbed, these soils are harmless, however when excavated or exposed to air, the sulfides within the soils oxidise and when moist, produce dilute sulphuric acid.

The acidic conditions can cause the leaching of toxic chemicals (such as heavy metals) creating toxic conditions that kill plants and animals, contaminate drinking water, food and corrode concrete and steel.

Landserv possesses extensive experience in the assessment and management of sites with existing or Potential Acid Sulfate Soils (PASS).

Selected Project Experience:

Acid Sulfate Soil Investigations for Melbourne Water Waterways Alliance

Landserv has completed a number of projects for Melbourne Water’s Waterways Alliance over more than 2 years. Many of these projects have involved the assessment and management of sites where naturally occurring ASS exist, while others involved the investigation of sites for PASS.

Melbourne Park and Olympic Park Redevelopment Projects – Soil Management

Landserv was engaged by Major Projects Victoria and then by Lend Lease Construction, to assist with soil management for the construction phase of the Melbourne Park & Olympic Park Redevelopment project. The project included the management of soil generated at the site during construction phase works. A portion of this work included the assessment and management of naturally occurring PASS identified at the site in underlying Coode Island Silts.
