While this seems dubious just because Camden also says it of Middlewich (see first Myths' Page), this kind of thing is, in fact, both found in nature and as a widespread myth where streams run close to each other. Jones* gives several examples, of which the following would seem to fall in the "myth" category: 1) The Well-streams of Dwyfan and Dwyfach that unite to flow through Lake Bala without mixing; 2) Ffynnon Nathan, Laugharne, where three wells each cure one of: eyes, rheumatism, and wounds; 3) Ffynnon Aberogwy (Ogmore-by-sea?), Glamorgan, where there are nine springs, each of a different nature; 4) Pistyll Meugan, half a mile east by north of Llanfair Nantgwyn church, where several streams of water south of the church never mix - one good for the eyes and warts, one rheumatics, and one clefyd y galon (literally "disease of the heart", but which you can take as you may). However, on the "possible" side of the balance are: 1) Penegoes Wells, Montgomeryshire/Powys, where there are two wells, one warmer than other; and 2) Gumfreston Church Wells, where there are two Chalybeate (Iron salt) wells and a pure water spring which trickles down from above them*.
