Is the Government planning to use bioremediation to stop acidification of the Lower Lakes?
Yes. Bioremediation is part of the Government’s plans to encourage natural processes to improve the environment surrounding the Coorong, Lower Lakes and Murray Mouth. It is a very effective way to manage acidification and research is underway to make sure the conditions are right for sulfate reducing bacteria to naturally reverse the acidification process. The bacteria use iron and organic matter in the water to consume the acid and studies are taking place to find out if more needs to be added in the future to encourage bacteria. It is expected that bioremediation will be supported in suitable locations where acid sulfate soils become exposed due to low water flows in the Lower Lakes. More information about Revegetation works in the Lower Lakes and limestone trials in Currency Creek and Finniss River is available online.
