The Environmental Police in São Paulo confirmed the disposal of untreated sewage into the Sorocaba River, particularly affecting the Parque São Bento neighborhood in the city's northern zone. This confirmation follows a report made by G1, prompting intervention from the Environmental Company of the State of São Paulo (CETESB), which has been collecting water samples from the contaminated area. This instance of environmental neglect is indicative of wider systemic issues concerning waste management in the region.

Local residents have been aware of the untreated sewage problem for at least three years, specifically in an area known as Chácara do Mineiro, despite the neighborhood's proximity to two Sewage Treatment Stations. The presence of untreated waste so close to treatment facilities highlights failures in sanitation management and enforcement of environmental regulations. The State Secretary of Public Security confirmed that the Environmental Police were dispatched to investigate the situation following the allegations.

The Environmental Company is currently negotiating a solution with both the municipality and the sanitation company responsible for the area to address the environmental crisis. Should effective measures not be implemented promptly, the ongoing pollution could have severe implications for local wildlife, public health, and the community’s quality of life. The revelations from this investigation call for increased accountability and immediate action to resolve existing sanitation shortcomings in São Paulo's urban areas.
