In 2024, the water quality of the Atlantic Atlantic Forest River did not show great signs of recovery in recent years, and compared to the previous year, there was an exacerbation, according to the 2025 rivers monitor Disturbing.
Among the water samples in 145 assembly points, in 67 municipalities from 14 states, only 11 points – only 7.6 % of monitoring places – were good quality, and in the second year, no perfect quality was recorded. See the results:
- Great: 0 %
- BOA: 7.6 %
- Regular: 75.2 %
- Spacious: 13.8 %
- Poor: 3.4 %
Water classified as “regular” is already “affected by pollution” and needs a treatment for human consumption, according to the report.
Compared to the previous year, there was an increase in the number of poor quality rivers and four -point vessels, which include Pinhiros RiverIn the city of Sao Paulo, and Ribirao Doss Minnos, at São Kaitano de Sol (SP).
When rivers are considered bad or poor quality, pollution reaches critical levels – which weakens both biological diversity and population that depends on these water resources and public health. “The study says: “Regular quality predominance requires additional attention to managers and society,” the study says.
The research indicates this The results of the 2024 monitoring show that the position of the Atlantic Forest River is still “out of idealism”: less than 10 % of the points that have been analyzed have good quality and none of them reach the optimal level.
Note to CNNThe Environment, Infrastructure and Logistics Services (SEMIL) in the state of Sao Paulo said that, in the past two years, “the largest historical withdrawal of sediments from the Tietê river and their tributaries through the Integratietê program, in addition to all monitoring, supervision, environmental recovery, and progress in basic health: 2.89 million cubic meters of sediments From the Tietê River and its tributaries.
The volume said that 600,000 cubic meters of sediments were removed from the Pinheiros River in the past two years, with more than $ 93 million invested. “It is also implemented on the Pinheiros River, floating waste, which reaches a waterway through rain or is thrown directly to the river by the population. From 2023 until now, 83.4 thousand tons of garbage has been removed from Rio, which costs the general decision $ 148 million,” says observation.
According to the CEESB CEOSB, in 2023, at the four control points of the company on Rio Pinhairus, a regular quality point, two poor quality and one of the poor quality. In 2024, data indicates an annual IQA improvement, a regular and three bad point. There was no point classified as terrible on the annual average.
