Blue Lagoon
The healing powers of wastewater

Blue Lagoon spa, Grindavík, Iceland

Let's be frank here, the origin of today's beautiful picture is a pool of wastewater from a nearby geothermal plant. While that may not sound enticing, Iceland's Blue Lagoon is one of the country's most visited attractions. The trick is to not get stuck on the 'waste' part of wastewater. The water here is clean, always hovers around 100° F, and is enriched with tons of silica—which is what makes it blue—and sulfur thanks to the plant's processes. Those minerals, along with a little algae, are believed to combine into a highly beneficial tonic for skin and overall well-being.
