Fontanalia

... youths,
Each with his maid, before the sun was up,
By annual custom, issuing forth in troops,
To drink the waters of some sainted well,
And hang it round with garlands ...

-- Wordsworth (The Prelude, Book 8)

Yes, oh glory, it did happen. There is a new water softener installed and running, and it is safe to drink the waters of our well (and wash white things) again.
