Short summary
Short summary
This study explored groundwater in western Finland to understand how underground water ages, flows, and supports microbial life. By combining chemical, isotopic, and biological analyses, researchers found that deeper waters are older and host different microbes than shallow ones. These findings help explain how groundwater systems work and support better management of this vital resource for drinking water supply.

Short summary
A monitoring network has been implemented to improve the understanding of the functioning of the Roya River alluvial aquifer. Data analysis proved the predominant role of surface water in the recharge of the aquifer. Following the storm Alex in October 2020, a general decrease of the piezometric levels was observed. It is explained by the changes in the river morphology and in the riverbed granulometry which limit the aquifer recharge by river water infiltration.

This work aims to develop the Transit Time index (TTi) as a natural tracer of karst groundwater transit time, usable in the 0–6-month range. Based on the fluorescence of organic matter, TTi shows its relevance to detect a small proportion of fast infiltration water within a mix, while other natural transit time tracers provide no or less sensitive information. Comparison of the average TTi of different karst springs also provides consistent results with the expected relative transit times.

Short summary
We studied the impact of occasional saltwater intrusions into the karst aquifer of the Balaruc peninsula (France). Using hydrogeological and geochemical data, this study shows that the hydraulic impact on the aquifer is rapid and of regional extent, whereas the geochemical impact is observed at the local scale and is temporally persistent. This research supports groundwater management by providing a better understanding of the hydrodynamics and recovery of the aquifer after saltwater intrusions.
