Overview
- COHIFE approved a resolution at its Mendoza assembly declaring the ITBA arsenic map unfit as a reference for characterizing Argentina’s groundwater.
- The council reports the samples were voluntary with no chain of custody, precise coordinates or depths, proper preservation, transport, or in‑field controls, and the institute acknowledged no field verification or checks against official databases.
- Because each point reflects a single reading, COHIFE deemed the map’s cartographic interpolations invalid for reliable spatial or temporal analysis.
- Member jurisdictions maintain that water supplied to residents meets current regulatory limits and is verified through continuous monitoring and treatment systems.
- Provincial responses included Tucumán’s water utility rejecting claims of local risk and citing compliance with the National Food Code.
