Acid Sulfate Soils Guideline Series
Draft Treatment and management of disturbed acid sulfate soils
and acidic ground and surface waters
1.0 Introduction
The disturbance of acid sulfate soils (ASS) by excavation, drainage or dewatering can cause
severe environmental problems unless managed correctly. Several management techniques used
to mange disturbed acid sulfate soils may also cause environmental risk unless they are
implemented correctly. Before any of the following management strategies are used, a proponent
should provide a risk assessment and documented scientific justification to the Department of
Environment and Catchment Protection (DEWCP) that the process will not impact on the values
of the receiving environment or pose a risk to public health.
2.0 Purpose of the Guidelines
The purpose of these guidelines is to provide information on:
- the management of ASS stockpiles and defining the level of treatment that is necessary to
neutralise existing acidity plus potential acidity associated with the disturbance of ASS;
and
- the levels of management and reporting that are expected for these treatment methods.
