Rain seeping into the pine forest
Rain falling on the mountains and forests does not run straight off. It seeps slowly into the ground and begins a long journey.
Beneath Cheongsong, a UNESCO Global Geopark, we found a calcium-sulfate source water with TDS of 523 mg/L. It is the first natural source water in Korea to qualify as mineral water under the US FDA standard.
Designated a UNESCO Global Geopark in 2017, covering 845.71 km². The name of this land is itself a brand asset.
In 2017 the whole of Cheongsong County became a UNESCO Global Geopark. Tap a dot on the map or a name below to explore a geosite.
Every layer has its own texture of dots. As you scroll, the layers the water passes through light up in turn.

Non-welded tuff and sedimentary rock hold rainwater and release it little by little. This structure is why Jusanji Reservoir in Cheongsong does not dry up, even in drought.
Dense welded tuff lies beneath, holding water like a great bowl. On the cliffs of Juwangsan you can see the columnar joints formed as this rock cooled.
Faults and joints criss-cross the Juwangsan area. Inside the hard bedrock, groundwater travels deeper along these cracks.
Water that has met the rock over a long time carries dissolved calcium and sulfate. Cheongsong source water is a calcium-sulfate (Ca-SO₄) mineral water.
See the mineralsEach dot is 1 mg. That is more than twice the US threshold of 250 mg/L TDS for mineral water. Tap a mineral to gather its dots.
The US FDA classifies water from a protected underground source, with no minerals added and TDS of 250 mg/L or more, as mineral water. Cheongsong is the first Korean spring water source to clear that bar. Every major Korean bottled water compared here sits below the line; Cheongsong source water measures 523 mg/L, more than twice over. Each dot is 10 mg/L.
Unit: mg/L. Cheongsong values are for the source water (Mineral 1). Korean comparisons cover bottled spring water; beverages with added minerals are not included.
CHEONGSONG NATURAL MINERAL WATER
Carrying the minerals the land has left behind, we are building a mineral water brand that begins in Cheongsong and reaches the world.
The source water measures 523 mg/L total dissolved solids. It is a calcium-sulfate type water with 135 mg/L calcium, 280 mg/L sulfate and 33.8 mg/L sodium; iron and manganese were not detected.
The US FDA (21 CFR 165.110) classifies water from a geologically and physically protected underground source, with no minerals added and at least 250 mg/L total dissolved solids, as mineral water. Cheongsong source water, at 523 mg/L, is more than twice that threshold.
The major Korean bottled spring waters compared range from about 40 to 133 mg/L TDS, all below the FDA mineral water line. Cheongsong is the first Korean spring water source to exceed it. Beverages with added minerals were not included in the comparison.
Within Cheongsong County, Gyeongsangbuk-do, designated a UNESCO Global Geopark in 2017. The exact location is not disclosed to protect the source.
