In Brazil, laws and regulations regarding the operation of public swimming pools or those for common use are maintained at local levels, such as municipalities. These regulations lack a national requirement mandating establishments to provide information on the water quality of their pools, leading to discrepancies in safety standards across different areas. Cities like São Paulo, however, have taken steps to address these concerns, as seen a decade ago when guidelines were established for public pool management.

The issue of water quality in swimming pools saw a sharp increase in scrutiny due to a recent tragic incident. Juliana Faustino Bassetto, a 27-year-old swimming instructor, reportedly died after a swimming lesson at a gym located in the Parque São Lucas neighborhood of São Paulo. Authorities, including the São Paulo Public Security Secretariat (SSP), suggest that her death may have resulted from toxic gases released from the chemical products used to clean the pool. Furthermore, it was reported that five other individuals experienced illness under similar circumstances, intensifying public concern regarding pool safety practices.

As a response to these and other incidents, local health authorities, such as the municipal health department in São Paulo, have attempted to implement more robust health and sanitation conditions to safeguard users of public swimming facilities. This push for stricter regulations highlights the need for better monitoring and transparency in the management of swimming pools, particularly in densely populated areas where public health may be at risk due to inadequate safety measures.
