Investigating the geogenic origin of atypical U characteristics – elevated U content, low (234U/238U) activity ratio – of groundwater in Beauce Limestone Aquifer System, France

Key Points

• Elevated uranium content and a low (234U/238U) activity ratio characterize groundwater in the aquifer.
• The analysis detected uranium levels significantly above typical ranges, indicating unique geogenic processes.
• Geochemical investigation within the Beauce Limestone Aquifer System explored the origin of uranium anomalies.
• Such findings may imply the need for further studies on groundwater management and safety assessments.
