What was the original source of the water that formed Iceland's now-famous Blue Lagoon?
Answer
Wastewater from a geothermal power plant
The Blue Lagoon was not engineered as an attraction — it formed accidentally in 1976 when mineral-rich wastewater discharged by the Svartsengi geothermal power plant pooled in the surrounding lava field. Locals began bathing in it before it was developed into a spa.
