Norsk Hydro sees no indications of leaks or overflow at Alunorte
Norsk Hydro said in a press release that it has no indications of leaks or overflow from Hydro Alunorte's bauxite residue deposit areas. "In order to release excess rainwater from the factory area, Alunorte released rainwater through the Canal Velho water canal. There is no indication of negative environmental impact from the release," the company said. On February 17, during the heavy rainfall that started the day before, and periodically between February 20-25, Hydro used a canal called Canal Velho to discharge pH treated rainwater from the factory area into the Para river, it added. The water was pH treated at the inlet to the canal, before it was released and then merged with water from the water treatment plant, as well as surface water from the Albras aluminium factory. "First of all, it is important to emphasize that we have no indication of leak or overflow from our bauxite residue deposit areas. We released rainwater from the factory area. The release was done as a controlled measure which we communicated to SEMAS, the state environmental agency," says President and CEO, Svein Richard Brandtzg.
