Identification and investigation of acid sulfate soils and acidic landscapes

Practical guidance on the identification and investigation of acid sulfate soils.
Last updated: 2 May 2023

This guideline provides guidance in relation to the minimum level of investigation required to:

  • identify the presence or the absence of acid sulfate soil (ASS) in areas likely to be disturbed by a proposed development or other project; and, if present
  • define the nature and extent of ASS and the amount of existing and potential acidity it contains in order to determine appropriate management measures.

Guidance on management measures for ASS can be obtained from Treatment and management of soils and water in acid sulfate soil landscapes.
