Willow Water’s mineral content is a unique blueprint that reflects the geology of the Cartmel area. Just below the surface on Cartmel Fell lies a deep layer of peat formed from the remains of a prehistoric forest of white willow trees. This ancient woodland once covered the southern Lake District in a dense canopy.
As rain falls on Cartmel Fell the rainwater travels through this layer picking up valuable salicin on its journey. A substantial layer of limestone provides a natural filter and also endows Willow Water with its significant calcium content.
The water travels down away from the fells peaks, picking up the remaining minerals which make up its unique composition, and forms the aquifer in the sand and gravel beds that exists below the Cartmel area.
Willow Water can trace its roots back to the 12th century when it was discovered by Augustinian Monks. This underground body of water is the source of the famous Holy Well of Cartmel, which has been renowned in the North West of England for its restorative qualities from the 1700s up to the present day. The water contains natural salicin and calcium as a result of the unique geology of this part of the Southern Lake District, which acts as a filter for rainwater on its way to the aquifer.
