Several tons of fish have died along one of the main rivers in Sao Paulo state after an alleged illegal dumping of industrial waste from a sugar and ethanol plant, environmental authorities and prosecutors said. A preliminary analysis estimates that between 10 and 20 tons of fish died on the Piracicaba river, according to prosecutors. The initial investigation points to an “irregular discharge of wastewater” from Estiva’s Sao Jose plant in the community of Rio das Pedras, and it reached a stream that flows into the Piracicaba River.
