Abstract

The expansion of irrigated fruit production in semi-arid regions, particularly in Brazil’s São Francisco Valley, has been accompanied by increased pesticide use and potential contamination of aquifers supplying rural and riverside communities. The central problem addressed in this study is the paradox between the economic success of irrigated agribusiness and the hidden public health burden associated with chemical residues in drinking water. The main objective was to critically review evidence on pesticide contamination of groundwater and its links to endocrine disruption and cancer in exposed populations. An integrative literature review was conducted between October 2025 and January 2026, using a closed corpus of 33 open-access references analyzed according to established methodological frameworks. Results showed recurrent detection of multiple pesticides in groundwater and drinking-water systems, predominance of highly mobile compounds, and mechanistic plausibility for carcinogenesis mediated by hormonal disruption, oxidative stress, and chronic inflammation. Epidemiological evidence indicated associations between chronic pesticide exposure and increased cancer risk, while regulatory analyses revealed limitations of substance-by-substance standards in addressing real-world mixture exposures. We conclude that contaminated aquifers represent a silent epidemiological pathway and a manifestation of water injustice in intensive agricultural regions, highlighting the need for territorialized monitoring, revised toxicological standards, and integration of agroecology, water security, and public health policies.
