Local signage states "The Spring Wells are natural artesian springs and if you look closely you will see the water bubbling up from the rocks deep below.
The springs are fed by the Lincolnshire Limestone Aquifer, with rain falling on the uplands near Grantham flowing downwards and eastwards along the dipping limestone strata and being forced up under pressure here.
The water is slightly warm and seldom freezes.
The water no doubt attracted early settlers and there is evidence of Iron Age and Roman settlement nearby.
The water is "chalybeate", meaning it contains iron salts, and as such would have been highly valued by the Victorians for health giving.
The cisterns where the Victorians drew their water by hand can still be seen on either side.
The springs have only dried up twice in living memory - in 1976 and in the drought of 2011 when the water did not reappear for 6 months"
