Acid Mud [electronic resource]

Summary
In many wetlands along the Murray and Darling Rivers, the recipe for acid mud is perfect. Sediments flooded for decades are being exposed to air as drought affected water levels fall. Waterlogged soils often contain sulfides produced by bacteria decomposing organic matter, but if these sediments are allowed to build up and are then exposed to oxygen, they form sulfuric acid. This video clip focuses on the problem of Bottle Bend, a once healthy wetland turned toxic waste site where nothing but microorganisms can survive the acid water and its steel-eating pH of 1.6.
