Overview
- After relaunching its interactive Mapa de Arsénico, the Instituto Tecnológico de Buenos Aires reported results from 350+ lab-tested samples showing exceedances in at least seven provinces.
- Coverage highlights widespread hotspots in Buenos Aires province, with local reports citing 66 municipalities showing elevated values and several locations above 50 ppb.
- The project classifies results by a three‑color scale, with the WHO guideline set at 10 ppb and a red category above 50 ppb where water should not be used for drinking or cooking.
- AySA stated that water distributed within its AMBA concession meets regulated arsenic limits, advising against using unmonitored private perforations without testing.
- Specialists warn that long-term ingestion can cause HACRE and is linked to higher risks of certain cancers, and ITBA has renewed its call for citizen sampling after pandemic-era declines.
