The river basin is in the 2,585,910 hectares (6,389,900 acres) Waimiri Atroari Indigenous Territory.[1] Tailings of processed tin ore from the Pitinga mine are held in holding ponds as a reserve that may be further processed if justified by a rise in the price of tin. In 1987 the dykes of four ponds broke. The sediment was released into the Alalaú River, and the pollution affected the fish downstream in the Waimiri-Atroari Indian Reserve.[2] The Indians reported that the polluted water had made them ill.[3]
