Soil Guidance Identification, sampling and analysis of acid sulfate soils should be conducted in line with the National acid sulfate soils sampling and identification methods manual and the National acid sulfate soils identification and laboratory methods manual - as well as the National Environment Protection (Assessment of Site Contamination) Measure 1999 (Cth) ('Site Contamination NEPM'). The Site Contamination NEPM is not specific to acid sulfate soils and is not discussed here.The national sampling and identification manual provides: background information on acid sulfate soil formation and disturbance processes and environmental impacts; the minimum requirements of a desktop assessment and site inspection; and a guide to sampling and field testing. The national laboratory methods manual provides: the action criteria triggering the need for an Acid Sulfate Soil Management Plan (ASSMP); a description of the key pools of actual and potential acidity; an overview of the hazards associated with the disturbance of acid sulfate soils (e.g., acidification, deoxygenation, and salinisation of soil/water systems, and mobilisation of metals/metalloids); and a description of the standard analytical techniques used to quantify these hazards (e.g., Acid Base Accounting, Acid Volatile Sulfide analysis, and sequential metal/metalloid extraction). These manuals do not provide guidance on the management of acid sulfate soils. For topic-specific management strategies see: Guidance for the Dredging of Acid Sulfate Soil Sediments and Associated Dredge Spoil Management; Guidance for the Dewatering of Acid Sulfate Soils in Shallow Groundwater Environments; and Overview and Management of Monosulfidic Black Ooze (MBO) Accumulation in Waterways and Wetlands. These documents are comprehensive and publicly available through the Water Quality Australia website. Queensland Guidance The Queensland Acid Sulfate Soil Technical Manual: Soil Management Guidelines is highly recommended for both scientists and engineers due to its excellent discussion on risk assessment and management strategies. Management strategies discussed in the manual include: avoidance, minimisation of disturbance, neutralisation, hydraulic separation, strategic reburial / interment, and stockpiling. The Queensland government Acid Sulfate Soils: Laboratory Methods Guidelines is recommended for a discussion on the analytical techniques. Although the National guidance constitutes the primary authority on the subject, and covers a broader range of issues, this manual provides more commentary on the analytical techniques such as SPOCAS. Western Australia Guidance The Treatment and management of soils and water in acid sulfate soil landscapes provides an overview of acid sulfate soil management strategies – including a discussion on groundwater management (which is not covered in the Queensland technical manual).
