A recent study by the Texas Water Resources Institute (TWRI) has shed light on the critical issue of transboundary aquifer vulnerability along the US-Mexico border. This research pinpoints areas facing significant pressure due to overutilization and provides essential data for water management.
The study focuses on identifying areas within 73 transboundary hydrogeological units that are particularly vulnerable to groundwater over-extraction. This analysis is crucial for understanding the potential impacts on both local communities and regional water resources.
Researchers utilized an approach called effective transboundary aquifer areas (ETAAs) to assess vulnerability at a refined, local level. This ETAA Analysis involved examining pumping density and depth information within the hydrogeological units.
Data was collected from all 73 hydrogeological units, allowing for the analysis of density within active pumping areas and depth information. The methodology confirmed well-density patterns and potential water movement across the border at local and regional scales. The identification of vulnerable areas allows for targeted interventions and the development of sustainable water practices.
The ETAA information can be used to:
- Estimate potential impacts of over-extraction and contamination.
- Inform the development of future water policies.
- Facilitate the assessment of shared groundwater conditions.
