No, the Blue Lagoon does not use chlorine as a disinfectant.
The Blue Lagoon, renowned for its unique geothermal seawater, operates without the need for traditional chemical disinfectants like chlorine. This is because the lagoon's ecosystem is naturally self-cleaning, primarily due to the distinctive properties of its mineral-rich waters. The high silica content and other active elements found in the geothermal seawater contribute to its inherent purity and hygiene, meaning disinfectants such as chlorine are not needed. In essence, the lagoon is a self-cleaning ecosystem.
The exceptional cleanliness and environmental standards of the Blue Lagoon are globally recognized. For over a decade, the Blue Lagoon has proudly received the prestigious Blue Flag eco-label. This esteemed international award is granted to beaches, marinas, and sustainable boating tourism operators that meet rigorous criteria across environmental management, water quality, safety, and services. The continuous recognition with the Blue Flag underscores the lagoon's commitment to sustainability and confirms that external chemical disinfectants, such as chlorine, are simply not necessary to maintain its pristine conditions.
This natural purification process not only ensures a unique bathing experience but also highlights the Blue Lagoon's dedication to preserving its natural environment and offering visitors a clean, naturally maintained geothermal wonder.
