          The banks of the creek and its surroundings have already been cleaned: earthwork equipment have removed the red mud and several centimeters of topsoil layer. The colour of the exposed soil is already black and the area is arranged. The soil mixed with the removed red mud layer was collected in prisms until sorting out of a final solution.
