Bruce,
At Droitwich the springs are fed with water that originates in the
Lickey Hills 20 miles away. When boreholes were sunk in 1725 they
discovered
a hard talc (gypsum) layer and when they broke through that a river of
brine
(cavity) they found it was one foot deep. There is a constant flow along
this brine run that has been mapped by geologists.
It was once thought that the flow in this brine run ws from Stoke
Prior to
Droitwich, but the last I heard this has been reversed. But it can be
noted
that the brine run at Droitwich is about 150 ft. deep, whereas at Stoke,
three
miles outside the town it is 800 ft. deep.
Maybe one day that can put cameras down there and determine exactly
how things work!
