What was the impact of that summer's drought on the region's groundwater? In the context of climate change, how can we better understand groundwater resources so as to use them more intelligently? The monitoring tools and scientific projects conducted by BRGM in Aquitaine provide answers to these hydrogeological questions and help stakeholders in the region make the right decisions.

Weather impact and climate change

To summarise, the year 2015 was generally less favourable than the two previous years for the Aquitaine aquifers despite a good winter recharge. The weather has an impact mainly on surface water tables, an impact that could be amplified in the future by climate change and lead to a transfer of some abstraction to deep water tables that are mainly tapped for drinking water.

Some of them are subject to increased monitoring as part of the 'Gironde deep groundwater Master Plan for Water Development and Management’, this being due to their local or regional overexploitation. To guarantee their long-term sustainability, BRGM, in conjunction with its technical and financial partners, carries out field investigations and digital simulations.
