“The basin committee, which decides the best investment strategy, believes that from now on it should have more effort to use the money in projects that could lead to new ways of raising more funds to the recuperation of the river,” explained Mansur.
Paraíba do Sul is one of the most important rivers in Brazil and it is located between the two largest Brazilian cities: Rio de Janeiro and São Paulo.
It crosses along 1.12 kilometers through a region with high population density and great concentration of industrial activities. The whole hydrographic basin comprehends three states in the southeast – Rio de Janeiro, São Paulo and Minas Gerais.
The charge for the use of water in Paraíba do Sul basin was the first one implemented in the country.

Satellites Used for Water Quality Control Support Environmental Inspecting in Paraíba do Sul River

A project developed together by Cetesb (Environmental Sanitation Technology Company of São Paulo), Inpe (National Spatial Research Institute) and the Committee of Paraíba do Sul hydrographic basin – São Paulo is proving to be of great importance to the environmental inspecting work in one of the most important Brazilian rivers.
Paraíba do Sul River crosses one of the main industrial poles of the country, in São Paulo state, and is also very important to the industrial cities of Rio de Janeiro state, like Volta Redonda and Resende. Project “Stations Net for Data Collection of the Quality of the Water of Paraíba do Sul River – São Paulo area” consists of a data collection system operated via satellites, called PCD.
The objective is to monitor and control the quality of the water measuring parameters of precipitation, river level, flow, acidity, turbidity, and dissolved oxygen, among other information.
“The data and measurements achieved with this technology help us to identify if there is anything abnormal in the quality of the water’s status. If it is the case, we open an investigation process to check, for instance, if there has been any release of prohibited effluents,” affirmed manager and technical coordinator of the project Mario Luiz Alves of Cetesb.
Alves explained that Cetesb has deep knowledge about the river, as monitoring devices have been developed for more than 10 years. Therefore, the company knows the normal parameter ranges of the river. Any number out of this range is considered to be an alert.
“This advanced technology allows us to know what is happening almost in real time. As a result, it is possible to fulfill a more effective environmental inspection work in the river,” said Alves.

Water Quality Improved Through Seedling Plantings
SÃO JOSÉ DOS CAMPOS, Brazil (OOSKAnews)
Forty thousand seedlings of native Atlantic forest trees have been planted in 35 nascents located in brooks near the Paraiba do Sul River in São José dos Campos located in the countryside some 90 kilometers from São Paulo, with a population of 500,000, is part of a pioneering project in Brazil.

Secretary for the city in 2006. The project involved planting of native plant seedlings in an area of 50 meters around the location of the nascent, which leads to an average of 1,500 seedlings planted at each point.
to inspect and maintain the growing trees for a minimum of two years. This should guarantee the conservation of the new young forest that will ultimately be responsible for a good quantity and quality of the waters that spring from the ground and form the Paraíba do Sul River.
and environmental education consultant of the secretary.
From the 35 nascents that are monitored by the project, five were “adopted” by companies
of the region, which became partners and are in charge of the planting and conservation
of their nascent points. Among these companies is Embraer (Brazilian Aeronautical
Company), whose main plant is located in São José dos Campos.
activities. These involve students, community leaders and residents from areas where the nascents are located, in hopes that they will become partners and continue the project.
By the end of 2007, 7,000 children had participated of the project’s activities, including
the ones in the field. Currently, the Environment Secretary is about to start the third phase of the project, which involves owners of private lands that have nascents on their property.
For the results achieved since 2006, this pioneering initiative was recognized by the National Water Agency (ANA) and the project is one of the final competitors of the ANA Prize 2008. Results of that competition will be announced in a month.
“It’s important to point out that the revitalization of the nascents does not consist only of the conservation of water resources. We are also contributing to recuperation and protection of biodiversity and the improvement of air quality, not to mention the contribution to control global warming,” explained Sundfeld.
