The Blue Lagoon geothermal spa is one of the most visited attractions inIceland. The steamy waters are part of a lava formation. The warm waters are rich in minerals like silica and sulphur and bathing in the Blue Lagoon is reputed to help some people suffering from skin diseases .The water temperature in the bathing and swimming area of the lagoon averages 3739C . The Blue Lagoon also operates a Research and Development facility to help find cures for other skin ailments using the mineral rich water. The lagoon is fed by the water output of the nearbygeothermal power plant Svartsengi and is renewed every 2 days. Superheated water is vented from the ground near a lava flow and used to run turbines that generate electricity. After going through the turbines, the steam and hot water passes through a heat exchanger to provide heat for a municipal hot water heating system. Then the water is fed into the lagoon for recreational and medicinal users to bathe in. (Global Volcanism Program)
