Ordnance Survey maps.
On the OS Explorer series (Scale 1:25,000) of Ordnance Survey maps, a well is denoted as a small unfilled blue circle with a blue capital "W" next to it. Springs are denoted by the same circle however the letters "Spr" are used in place of "W".The smaller scale maps (i.e. showing a larger area) such as the OS Landranger series (Scale 1:50,000) do not appear detailed enough to display wells (and they do not appear in the Key).See related links.
The boundary symbols vary depending on what type of Ordnance Survey may you are viewing though very often the main symbols are show in the margin of the map or on a webpage linked to Internet Maps

The name dates back to World War II. Much of the mapping carried out during the war was done by the Department of Ordnance (the guys who take care of munitions, artillery, tanks etc.). Their maps then, were known as Ordnance Survey maps. Today, Ordnance Survey maps are carried out by civilian teams and have nothing to do with ordnance but the name has stuck.
