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.
