Astonishing power of Harrogate Water

On a recent trip to Scotland we stayed at our favourite staging post, The Golden Fleece Hotel in Thirsk. Now, Thirsk is in Yorkshire and Yorkshire people are not backward in coming forward. 

In our hotel room we were supplied with a complimentary Yorkshire refreshment in the form of Harrogate Spring Water.

I was astonished at the capabilities of this water as declared on the label by the bottler. Was it really capable of enriching the rock with minerals as they so proudly claimed?
Or is this just Yorkshire people bragging again?
