Acid sulfate soil manual

The national manual describes laboratory methods which can be used to conclusively identify the presence or absence of acid sulfate soils, to quantitatively assess the associated hazards, and includes a section on interpretation of laboratory results.

If choosing SPOCAS analysis, the methods to calculate net acidity and liming rates must be consistent with the definitions contained within the National Guidance Material.

For further advice on laboratory methods contact: soils qld. For advice on dredging acid sulfate soils, refer to the Guidelines for the dredging of acid sulfate soil sediments and associated dredge spoil management PDF, 2.

For advice on dewatering acid sulfate soils, refer to the National acid sulfate soils guidance: guidance for the dewatering of acid sulfate soils in shallow groundwater environments PDF, 3. For advice on monosulfidic black oozes, refer to the National acid sulfate soils guidance: overview and management of monosulfidic black ooze MBO accumulations in waterways and wetlands PDF, 2. For general information on other legislation and policies relating to acid sulfate soils in Queensland.

A positive reaction, resulting in a color change, indicates the presence of reduced FeS, which quickly oxidize and change color upon application of hydrogen peroxide.

This method is only for detection of monosulfides and is not applicable to other sulfides e. Soils are considered potential acid sulfate soils if they contain reduced monosulfides. Atkeson, T.

These metals can be released in toxic amounts. Most of the current problems with acid sulfate soils in NSW have arisen from past practices in drainage and flood-mitigation. Major drainage works were built on floodplains from the Tweed to the Shoalhaven Rivers from the late s until the mids. Drainage and excavation of acid sulfate soils remains a current issue for urban development, infrastructure and sand mining. Because of their estuarine origin, they are usually found at elevations less than 1 metre above sea level.

Acid sulfate soils are common in mangrove and saltmarsh areas. They underlie floodplains, levees and backswamps. Acid sulfate soils may affect more than , hectares of land. About , hectares of this land are in agricultural production. Other notable locations include the Hunter and Shoalhaven rivers. Inland acid sulfate soils occur on inland waterways, wetlands and drainage channels. Like their coastal cousins, inland acid sulfate soils develop in waterlogged, saline and anaerobic which means living without air conditions.

This long period of drought reduced water levels and exposed acid sulfate material which oxidised and released acid and metals into inland waterways. The best known occurrence of inland acid sulfate soils is along the Edward-Wakool River system which extends into Victoria.

Inland acid sulfate soils are often associated with salinity sites and many have not been properly identified. The results were published in Aspects of Quaternary geology, geomorphic history, stratigraphy, soils and hydrogeology in the Edward—Wakool channel system, with particular reference to the distribution of sulfidic channel sediments PDF The report identifies the locations and risks of inland acid sulfate soils to rivers and streams in the Murray Darling Basin.

The report is based on landform assessment, extensive fieldwork. These maps predict the distribution of acid sulfate soils. They are based on landform assessment, extensive fieldwork and laboratory testing.
