Overview
- ITBA reports that about 70% of Buenos Aires province shows arsenic contamination, with many municipalities exceeding 50 ppb.
- The dataset suggests potential exposure for more than four million people across Buenos Aires, Córdoba, Santa Fe, Entre Ríos, Santiago del Estero, Tucumán and La Pampa.
- Chronic ingestion is linked to HACRE and higher risks of lung and laryngeal cancers, chronic cough and pulmonary fibrosis.
- Experts note greater risk where households rely on private wells or shallow groundwater without routine utility testing.
- AySA says water within its concession remains below regulated arsenic levels and is continuously monitored from source to distribution.
