The water of the Euganean Spa springs from a source 1500 mt above sea level in the Little Dolomites area. The rain water penetrates underground to a depth of 3000 m where it becomes rich in mineral salts and is gradually heated. It takes more than 25 years to run 100 km and to reach the Euganean area where water comes out from the spa wells.
When thermal water springs out, it has a temperature of about 87° C and it is used to mature mud but it is used also as a treatment in the thermal baths, for inhalation therapies and in thermal swimming-pools where the hydro-kinetic-therapy and medical hydro-gymnastics take place.
	Thermal mud is made of a combination of clay, bromide-iodine-salt water, micro-organisms and biomaterials. The maturation process occurs in specific tubs where high temperature and the chemical components of the thermal water make the particular micro-flora develop enormously.
