Natural curative sources of the biggest Spa in Slovakia - Piestany owes its reputation mainly to its unique natural springs of thermal mineral water, which rise from a depth of over 2,000 metres. These springs bring to our waters many specific chemical compounds and energy from the earths depths. This water is the main factor in the formation of our incomparable healing curative sulphur mud. It is a uniquely peculiar peloid which is the result of long-term reactions of thermal water with local soft rocks and specific bacterial micro flora.
The unique thermal water contains 1,500 mg of mineral elements per litre of water, and is trapped at a depth of 60 m, which guarantees a constant chemical composition and temperature. The water temperature of the 10 springs at the outlet is from 67 to 69°C, and it is used for baths and drinking cures.
The most important component for treatment of diseases of kinetic locomotive apparatus is the high content of sulphur (from 6 to 10 mg per litre), which occurs in the water in various forms and chemical compounds (sulphates, sulphites, sulphides). Even the high content of hydrogen sulphide is important –on average 4,7 mg per litre of water.
