Source ferrugineuse de Laifour, Iron-rich spring in Laifour, France.
Source ferrugineuse de Laifour is an iron-rich spring on the right bank of a Meuse River bend that produces water with high mineral content. The water emerges from a rocky formation and creates distinctive deposits as it flows.
Chemical analysis in 1812 revealed carbonic acid and iron in the mineral water, prompting comparison with Spa springs. This discovery sparked scientific interest in understanding the source's composition.
Local residents call such iron-rich springs "pouhons", which reflects the regional term for these natural water sources. This name has remained part of the local vocabulary for generations.
The spring water remains safe to drink during transport and medical professionals recommend limiting consumption to around one bottle per day. Visitors should plan their visit during favorable weather to safely access the site near the riverbank.
The reddish-orange deposits from iron oxide create a striking visual pattern in and around the spring's pool. These colored mineral deposits form as the iron in the water reacts with air and surrounding rocks.
