The Acid Sulfate Soils Research Program was undertaken to fill critical knowledge gaps related to the risks posed by exposure of acid sulfate soils in the Lower Lakes. Five research areas were examined:
- an acid sulfate soil spatial heterogeneity/mapping survey
- measurement of acid generation rates
- assessment of the in-situ contaminant generation, transport and neutralisation processes
- laboratory and field studies of the potential for mobilisation of contaminants following inundation with seawater compared to river water
- geochemical modelling of lake water quality.
Detailed findings from these projects are published in the following reports. In addition, the Acid Sulfate Soils Research Program Summary Report summarises the key findings of all of the projects and provides answers to frequently asked management questions.
The Acid Sulfate Soils Research Program is part of the South Australian Government's $610 million Murray Futures program funded by the Australian Government's Water for the Future initiative. Several projects were also supported by the Murray-Darling Basin Authority.
