Chlorpyrifos is a pesticide widely used in Brazilian agriculture, whose environmental and health relevance has been reinforced by international restrictions. The present study aimed to evaluate the environmental fate, use and occurrence of this compound in Brazil, with an emphasis on its presence in water intended for human consumption. For this purpose, sales data from 2009 to 2023 were analyzed and spatially distributed according to the cultivated areas of authorized crops, through the compilation of data from IBGE, Anvisa, and Ibama. The methodology also included the treatment of censored data, as well as temporal and spatial assessments of the concentrations reported in Sisagua from 2020 to 2025. The results revealed a high potential for surface water contamination and variability in national use, with greater intensity in the Central-West and Southeast regions, in addition to the detection of the compound in many water supply systems, generally below the maximum acceptable value. It was concluded that, despite the recent inclusion of chlorpyrifos as a Persistent Organic Pollutant under the Stockholm Convention, its environmental occurrence and significant commercialization remain a reality in the country.
