The word "chalybeate" is derived from the Latin word for steel, chalybs, which follows from the Greek word khálups. Khálups is the singular form of Khálubes or Chalybes, who were mythical people living on Mount Ida in north Asia Minor who had invented iron working.
Ferruginous  comes from the Latin word ferreus meaning "made of iron", which is derived from the Latin word ferrum, "iron".
Early in the 17th century, chalybeate water was said to have health-giving properties and many people once promoted its qualities. Dudley North, 3rd Baron North, discovered the chalybeate spring at Tunbridge Wells in 1606. His eldest son's physician said the waters contained "vitriol" and the waters of Tunbridge Wells could cure:
the colic, the melancholy, and the vapours; it made the lean fat, the fat lean; it killed flat worms in the belly, loosened the clammy humours of the body, and dried the over-moist brain.
He also apparently said, in verse:
These waters youth in age renew Strength to the weak and sickly add Give the pale cheek a rosy hue And cheerful spirits to the sad.
In 1689, a spring of ferruginous water rich in gas and tasting pleasantly was discovered by Count Lelio Piovene of Vicenza. Local residents called the water from this spring "Saint Anthony's miraculous water" believing it had therapeutic properties. This spring, known today as the Recoaro Spa, is located on the outskirts of Vicenza, in northeastern Italy.
John Radcliffe (1652-1714) discusses the benefits of various mineral waters in the chapter entitled "Of Chalybeat Waters" in his book Dr. Radcliffe's practical dispensatory : containing a complete body of prescriptions, fitted for all diseases, internal and external, digested under proper heads.
Anthony Relhan (c. 1715-1776), promoted the drinking of mineral waters and particularly water from the chalybeate spring in St Anne's Well Gardens, Hove and published A Short History of Brighthelmstone; with Remarks on its Air, an Analysis of its Waters, Particularly of an uncommon Mineral one, long discovered, though but lately used in 1761. This led to a substantial increase in public interest in drinking mineral water. The town of Enfield, New Hampshire, even changed its name temporarily to Relhan because of the profound public interest in this form of therapy.[failed verification]
This rather ornate spring well is in the village of Quarndon. A plaque inside the well has the following description "17th century chalybeate spring well. Once famous spa noted for medicinal waters containing iron. Visited by Daniel Defoe in 1727"
Spa situated in a valley in the Ardennes mountain chain, some 35 km (22 mi) southeast of Liège, and 45 km (28 mi) southwest of Aachen whose name is known back to Roman times, when the location was called Aquae Spadanae.
Bermondsey Spa, south-east of the Tower of London. Around 1770 Thomas Keyse opened some tea gardens. With the discovery of a chalybeate spring the gardens became known as Bermondsey Spa. About 1784 Keyse received a licence to "provide in his garden musical entertainments" like those in the Vauxhall Pleasure Gardens. They were varied by occasional exhibitions of fireworks and the price of admission was one shilling.
