Emerald green microbial pond

 

The green colour of the wonderfully distinctive pool is from a combination of dissolved minerals and heat-loving microorganisms. It has high concentrations of sulphur, iron, and other mineral deposits in the water. Additionally, thermophilic algae and bacteria, which thrive in the hot, mineral-rich environment, often produce pigments that contribute to the green coloration. The specific shade of green can vary depending on the mineral composition, acidity, and microbial activity within the pool. There are numerous pools nearby, however this is the only one that is green.
