The aim of this study was to identify organochlorine (OC) and organophosphorus (OP) pesticides levels in water samples collected in secondary water bodies in agricultural area planted with coffee and plantain. A descriptive cross-sectional study was carried out. A validated method for microwave-assisted extraction and gas chromatography with electron microcapture detector (MAE-GC-µECD) was used to analyze pesticide residues in samples. The determinations were based on certified reference material, Organochlorine Pesticide Mix AB #3, Canadian Drinking Organophosphorus Pesticides Mix, and pentachloronitrobenzene (ISTD) Internal Standard Mix 508.1. Pesticide residues were found in 81.3% of the samples, including OCs: 4.4'-DDT (38%), endosulfan II (19.7%), endosulfan sulfate, and endrin (11.7% and 8.8%), and others identified as 4.4'-DDE, Delta-HCB, parathion, chlorpyrifos, endrin aldehyde, heptachlor, heptachlor epoxide, endrin ketone, and methoxychlor. Parathion and/or chlorpyrifos were found in 5.8-8% of samples; the water bodies most heavily affected were those in Filandia and Quimbaya in which 100% of samples were contaminated, followed by those in Calarcá, Córdoba, Pijao, and Génova, with contamination found in over 75% of samples. The results indicated that surface waters from Quindío municipalities are contaminated with pesticide residues hazardous to human health, which are still in use despite being either restricted or prohibited.
