Thailand’s Department of Groundwater Resources has discovered an underground, highly carbonated and drinkable water source in Kanchanaburi province.

The department’s director-general, Sakda Wichiensilp, said that this is the first of its kind to be discovered in Thailand. He said that the fizzy water even tastes slightly sweet.

The department discovered the carbonated water during the search for underground water resources for farmers in the area. The one with the carbonated water is the third well being drilled in Laokwan district and it struck water at a dept of 303 meters. The water currently shoots up to around 1.8 meters above the surface at a rate of about 50 cubic meters per hour.

Sakda said the water becomes carbonated through the layers of mineral-rich limestone.
