Acid Sulfate Soil testing & management

Acid Sulfate Soils (ASS) are a serious environmental and structural risk in coastal and low-lying Queensland. Many development sites require ASS assessment as a condition of Development Approval — and getting it wrong can cause irreversible damage and costly remediation.

ASCT provides the full spectrum: sampling, laboratory testing, risk classification, and complete ASS Management Plans that satisfy council and DESI requirements.

1

Site Investigation & Sampling

Field investigation including borehole drilling, soil sampling, and field screening using hydrogen peroxide tests.

2

NATA Laboratory Analysis

Chromium reducible sulfur (CRS), pH testing, and net acid generation (NAG) testing in our accredited labs.

3

Risk Classification Report

Formal report classifying actual ASS (AASS) and potential ASS (PASS) risk levels to Queensland state planning requirements.

4

Management Plan

A full ASS Management Plan detailing treatment, neutralisation, and handling procedures — ready for your DA submission.

ASS Risk Classification

Low Risk
Low
Moderate Risk (PASS)
Moderate
High Risk (AASS)
High

ASS testing is required under Queensland's State Planning Policy for any development that involves soil disturbance below 5m AHD, or within designated ASS risk areas identified by council mapping.
