Resumen

Introduction: The quality of water for human consumption is essential for public health, with a more notable impact in rural areas. The presence of heavy metals in water can pose serious health risks. Objective: To assess the quality of water intended for human consumption based on metal levels determined using spectroscopic techniques. Methods: Twenty-six water samples were collected from various sources in the Ongoy district, Apurímac, of which 22 were selected for analysis. These included groundwater intakes, chlorination tanks, and residential taps. The protocols of the General Directorate of Environmental Health and Food Safety were applied for sample handling and transportation, ensuring their conservation under controlled conditions. Metal concentrations were analyzed using Inductively Coupled Plasma Optical Emission Spectrometry and Atomic Fluorescence Spectrometry. Results: The analyses revealed that most metal concentrations were within the limits allowed by regulations. However, some samples showed elevated levels of aluminum (up to 0.130 mg/L) and barium (up to 0.135 mg/L). Cadmium and chromium were undetectable, while sodium concentrations reached significant levels (up to 1183 mg/L). Conclusions: Although water quality in Ongoy is generally adequate, the elevated levels of aluminum and barium in certain samples highlight the need for continued monitoring and treatment.
