Blue Lagoon (geothermal spa)
lake in Iceland From Wikipedia, the free encyclopedia
The Blue Lagoon (Icelandic: Bláa lónið [ˈplauːa ˈlouːnɪθ]) is a geothermal spa in southwestern Iceland. The spa is located in a lava field 5 km (3.1 mi) from Grindavík and in front of Mount Þorbjörn on the Reykjanes Peninsula, in a location favorable for geothermal power, and is supplied by water used in the nearby Svartsengi geothermal power station. The Blue Lagoon is approximately 20 km (12 mi) from Keflavík International Airport, and is one of the most visited tourist attractions in Iceland.
The Blue Lagoon is man-made. The water is a byproduct from the nearby geothermal power station Svartsengi where heated water is transported from the ground near a lava flow and used to run steam turbines that produces electricity. After going through the turbines, the steam and hot water passes through pipes to provide heat for the settlements. Then the water is fed into the Blue Lagoon.
The water temperature in the bathing and swimming area of the Blue Lagoon averages 37–39 °C (99–102 °F).
The water's light blue color is due to its high silica content.[1] The silica forms soft white mud on the bottom of the lake which bathers rub on themselves. The water is also rich in salts and algae.[2]
