Guarapiranga dam (São Paulo-SP/Brazil) nitrogen distribution. In: IWA EASTERN EUROPEAN CONFERENCE FOR YOUNG WATER PROFESSIONALS, 9th, May 24-27, 2017, Budapest, Hungary. <b>Proceedings...</b> Disponível em: http://repositorio.ipen.br/handle/123456789/28612.http://repositorio.ipen.br/handle/123456789/28612Nowadays Guarapiranga Dam is responsible for about 20% of Metropolitan Region of São Paulo (RMSP) water supply. However, since the 60s an irregular and disordered occupation appears in the area. From the 70’s, the reservoir was reported eutrophic due to untreated urban sewage. Cyanobacteria blooms were frequent since 1990. Nitrogen species are a significant part of this eutrophication problem. In this scenario, the present work presents the distributions of nitrogen species in the Guarapiranga Dam, to compare with other lakes and reservoirs status in the world and to find options to this nutrient management in Guarapiranga Reservoir.openAccessnitrogensurface waterswater supplyeutrophicationlakeswater pollutionenvironmentenvironmental impactsTexto completo de eventohttps://orcid.org/0000-0002-6462-4758
