Someone mentioned that it would be useful to know the starting point of the water for which I gave the various treatments. So here you go.
I don't have the details for Wiveiscombe, but I do for London.

Both Fullers and Barclay Perkins had their own wells which they used as the source of their brewing water. Such waters were relatively low in sulphate but with reasonable levels of carbonate. The standard water supply, to which brewers would switch in the 20th century when their wells became contaminated, contained significantly fewer minerals.

Burton waters, on the other hand, often contained insane levels of sulphate. Though the exact makeup varied considerably, depending on the well’s depth.
