What does chalybeate mean?
Chalybeate describes water or springs that contain iron in solution, usually noticeable by a distinct metallic taste and often by a reddish deposit left where the water flows. The term is most closely associated with the spa culture of seventeenth- to nineteenth-century Europe, when drinking iron-rich waters was believed to cure ailments such as anaemia and general weakness; famous chalybeate wells drew fashionable visitors to towns including Tunbridge Wells and Harrogate. Used mainly as an adjective ('a chalybeate spring'), it also appears occasionally as a noun meaning the water itself or the spring that yields it. The word is formal and somewhat archaic in flavour today, surfacing mostly in historical writing, tourism literature about spa towns, and descriptions of geology or hydrology. For anyone reading accounts of historic resorts or natural mineral waters, it is the precise, established term for iron-bearing waters.
(Of a spring or water) containing iron salts in solution, especially with a perceptible metallic taste.
"The physician prescribed daily draughts from the chalybeate well as a remedy for her fatigue."
Almost always used attributively with 'spring', 'water', or 'well'.
Iron-rich mineral water, or a spring from which such water flows.
"Eighteenth-century travellers made long journeys to take the waters at the celebrated chalybeates of Yorkshire."
Used when referring to multiple iron-rich springs or sources of such water; the plural of the adjective sense does not apply.
"The region's chalybeates attracted health-seekers throughout the Georgian era."
England's spa towns like Tunbridge Wells were built entirely on 'chalybeate' water — water so full of dissolved iron it literally tasted of metal, yet crowds flocked to drink it as medicine.

Etymology of chalybeate
Chalybeate derives from Latin chalybeius, meaning 'of steel or iron', which in turn comes from Greek Chalybes, the name of an ancient people of Asia Minor renowned for their skill in working iron. The word entered English in the early seventeenth century, when physicians and writers applied it to medicinal iron-rich springs. It shares its origin with the rarer mineral term chalybite, another name for the iron carbonate siderite.
How chalybeate is actually used
A formal, somewhat literary word encountered chiefly in historical, geographical, and spa-related contexts. It carries connotations of old-fashioned health cures and Regency-era resort towns, and is rarely used outside descriptions of mineral springs.
