What is being done about acid sulfate soils?
The South Australian Government is working on a comprehensive program for managing acid sulfate soils that are exposed along the River Murray and around the Lower Lakes due to critically low water levels. Current work includes: • Researching where acid sulfate soils are found in the Murray wetlands, river channel and Lower Lakes, and what their characteristics are and how they are best managed • Increasing monitoring of acidity and salinity in the River Murray and Lower Lakes and working to predict acidity levels over the next 12 months • Trialling bioremediation methods in the Lower Lakes area, such as keeping lake sediments wet where possible, growing plants along exposed shorelines including adding limestone to the soil to reduce reduce its acidity • Treating acidification in the Finniss River and Currency Creek area by adding limestone to the lakebeds and water as an emergency response measure • Building temporary water flow regulators in the Goolwa Channel region to help keep soil
