Time series of dissolved oxygen (DO), biochemical oxygen demand (BOD), nitrate, total phosphorus, chloride, ammonia and faecal coliforms (FC), monitored by CETESB ('Companhia de Tecnologia de Saneamento Ambiental'), in the period from 1979 to 2001, were analysed in seven river basins located in the São Paulo State, one of the most developed regions in Brazil. The selected rivers, Piracicaba, Mogi-Guaçu, Turvo Grande, Peixe, Aguapeí, São José dos Dourados and Alto Paranapanema have different degrees of development concerning industrial, agricultural and population growth. Trend analysis methodology was based on graphical exploratory analysis followed by confirmation through statistical tests. Results showed impoverishment of the water quality conditions in most of the studied basins, represented by the positive trends of the parameters (BOD, nitrogens, total phosphorus, clorate and FC) and negative trend of the parameter (DO). Among the analysed basins, the Piracicaba River is the most severely affected with higher variations in the magnitude followed by the basins of the Mogi-Guaçu, Turvo Grande, Peixe and Aguapeí Rivers. On the other hand, the Alto Paranapanema and São José dos Dourados basins are the least affected.

As in the great civilizations, in Brazil, the first settlements were established and developed near major waterways creating a great responsibility in maintaining them. The aim of this study was to assist in the implementation of environmental legislation as there is consensus on the need for urgent measures. Almost all Brazilian legislation, including the 1988 Federal Constitution and Federal Law No. 9.433/97, consider rivers and streams conservation. This study was conducted in an urban stretch of the Cuiabá River (Mato Grosso, Brazil) along a gradient of organic pollution. Analyses were performed in times of drought and flood, with the aim of assessing the sanitary quality, biological and physical-chemical water properties. Moreover, algae and cyanobacteria indicators of different degrees of organic pollution were inventoried. The samples were collected along the river channel in February and August 1999. Fecal coliforms, total coliforms and others were quantified. The cyanobacte...

The Water Code, created in 1934, was the first attempt of governmental intervention in Water Basin Management in Brazil. It was a centralized bureaucratic system established to regulate the use of water. Since the beginning, Water Management suffered significant changes and the model currently used is an integrated participative systemic model. The distribution of water resources in Brazil is very irregular, 70% of water is located in the North region, 15% to the Central-West, 12% in the South and Southeast and 3% in the Northeast region (BNDES 1997). The state of São Paulo is located in the Southeast region, which has the biggest water consumption. The Water Resources Agency of São Paulo State (CETESB) has an advanced water management system with 20 Watershed Management Committees. Groups from different social sectors compose these committees. They constitute a new kind of organization that is responsible for the watershed planning. Actually, these committees use to obtain relevant information but they are not able to develop future scenarios, objectives, strategies and temporary goals for the water basin. The Mogi-Guaçu watershed is the most important basin in São Paulo State from the economic point of view, but the river has problems of erosion, silting, flooding and low water quality. The water quality problems are due to nonpoint sources of pollution from agriculture and municipal and industrial point sources.

Water Quality Monitoring as a Tool for Sustainable Management of the Upper Paraíba River Course
Revista Acta Ambiental Catarinense
No semiárido nordestino as características climáticas e as pressões socioeconômicas associadas ao uso da água, contribuem para alterar a quantidade e a qualidade dessas águas nas bacias hidrográficas. Como alternativa para minimizar os problemas de déficit hídrico foi implantado o Projeto de Integração do rio São Francisco, que visa levar água da Bacia do rio São Francisco às bacias em quatro estados brasileiros, por meio dos Eixos Leste e Norte. Nesta pesquisa foi analisada a qualidade da água no Alto Curso do rio Paraíba, no Eixo Leste, através da avaliação dos parâmetros físico-químicos da água e dos índices de qualidade de água e de estado trófico, antes e após início da operação do projeto de integração. Entre os parâmetros analisados, o fósforo total, nitrogênio total, sólidos dissolvidos totais e demanda bioquímica de oxigênio, predominaram fora dos limites recomendados pela Legislação brasileira, tanto sazonalmente como ao longo do trecho estudado. Para os índices de qualida...

Water Quality Study of the Itaparica Reservoir, São Francisco River, Brazil
Engineering and industry, 2016
The reservoir of Itaparica is located in the physiographic area called São Francisco sub-medium region, Brazil. It was constructed in 1987 with the priority purpose of energy generation. However, it presents multiple uses as public and industrial supplying, irrigation, aquaculture, cattle, navigation, and tourism with great part of its irrigated perimeter using fertilizes, and irregular occupations on its surrounds, as well as several kinds of effluents coming directly into the reservoir without treatment. The purpose of this work was to evaluate the water quality of the Itaparica reservoir using the monitoring and bibliographical sources, as a support to management improvements and consequently, improvements on the water resources in the semi-arid region of Pernambuco. Water quality degradation was observed along the years, and the reservoir is in eutrophization process, with concentrations of total phosphorus, and phytoplankton out of the standards established by Resolution Conama nº 357/2005. Implementation of control action becomes important like the reduction of sewage effluents inputs and the protection of the permanent preservation areas. An increase on the spatial and temporal frequency sampling data of the water quality becomes necessary, and it should set up new sampling points for a better evaluation of the eutrophization in the reservoir.
Surface water quality assessment of the main tributaries in the lower São Francisco River, Sergipe
RBRH, 2018
Contamination of water body by diffuse and point sources in springs has caused concerns mainly due to restrictions on its quality. The problem becomes more serious when contamination affects water for human consumption, as occurs in the river São Francisco, which supplies several municipalities of Sergipe. In this sense, the objective of the study was to evaluate water quality in eleven tributaries of the São Francisco river in its low course in the period from 2013 to 2014, in order to subsidize decision making by public management bodies operating in the region. For this purpose, it was used the Water Quality Index (WQI) and the Trophic State Index (TSI), as well the hierarchical grouping techniques associated to the samples to compare the different causes of contamination of each source. The lowest WQI values were observed in the rivers Betume and Jacaré and they were associated with high concentrations of coliforms related to the disposal of domestic effluents from the riverside...
