🚨 After the beauty (part 1), history (2) and use (3) of groundwater, part 4 of ' ' is a warning: Groundwater Equilibrium in Danger!

💧 For centuries, groundwater has been used by societies and recharged by precipitation. So, why is groundwater depleting so rapidly? In the 4th GeoStory we analyse the following challenges:

🚱 Depletion
🏚️ Subsidence
🕳️ Sinkholes
🌊 Floods
🧪 Contamination

🎞️ Our very first episode of 'Groundwater Explained', a series of explainer videos is fully dedicated to ! Launched today along a new policy brief 👇

💧 But what are PFAS? Why are they relevant now? And why should you know about them? These questions (and more) are explained in this video.

🗒️ The global PFAS situation asks for decisive and immediate action. Which is why Marie-Amélie PÉTRÉ, Ph.D., Geological Survey of Finland (GTK) and IGRAC wrote the policy brief ‘PFAS in groundwater: the invisible path to our drinking water‘. In this policy brief we call upon decision makers all over the world. It is now available here: https://un-igrac.org/latest/stories/groundwater-explained-pfas/.
