Chaco Province, Argentina

Overview

In the rural Chaco region of Argentina, many Indigenous and farming communities face chronic water shortages and dangerously high levels of arsenic and salinity in shallow wells. This GWB-funded project brought geoscientists, students, and local organizations together to apply geophysical methods to locate new, safe groundwater sources.

Approach

Using electrical resistivity surveys, the team mapped subsurface conditions to identify deeper aquifers with potable water potential. Field teams collaborated closely with local residents and municipal authorities to ensure that community priorities guided the site selection and well-drilling process.

Impact

10 new wells drilled in Miraflores and surrounding communities

Improved access to safe water for more than 2,500 residents

Training provided to local technicians and students for long-term monitoring

Reduction of arsenic exposure, improving overall health outcomes

Paleochannel mapping further informed the location of productive aquifer for the community’s long-term water security
