Filtered by Ancient, Deep-seated Volcanic Rock

Jeju Samdasoo is groundwater found in the layer of volcanic rock 420 meters underground and formed some 500,000 years ago.
The source of Jeju Samdasoo is under a superbly-preserved primeval forest near Hallasan National Park, free and far from contamination. Since it is 420 meters deep underground, contaminants are easily kept at bay. Jeju Samdasoo has been top quality water for the two decades since its release in 1998.

Water from Volcanic Rock When we say our water comes from volcanic rock, we mean it. Jeju is a volcanic island created and shaped by volcanic activity that began approximately 1.9 million years ago and ended about 5,000 years ago. Thin layers of lava, about 3 – 5 meters thick on average, are stacked on top of one another, and it is within these layers that we find our water.

Distinct and Impregnable Geological Structure

The source of Jeju Samdasoo is kept clean by the island’s natural system of quality assurance, keeping contaminants out of the source and ensuring consistency and safety. Jeju Samdasoo is protected by the island’s unique geological features: 7 – 8 layers of sedimentary stratum whose relative impermeability assures that water is safe and clean. Water flows through the crevices between volcanic rock, picking up vanadium, silica, and other minerals along the way. By the time it reaches us, it is healthy, naturally alkaline, and pleasant to drink.

Jeju Samdasoo - Filtered by Nature, from Rain to Bottle, for 18 Years

Jeju was formed by volcanic activity that began 1.9 million years ago and ended about 5,000 years ago. Comprised of lava beds 2-3 meters thick and sedimentary layers stacked on top of one another, the island’s strata act as one massive natural water filter.
When it hits the ground, rainwater (including melted snow) flows through the cracks and gaps of the lava bed and slowly permeates deep underground. Filtered pure and clean during the process, Jeju Samdasoo is the result of going through the earth’s largest natural water filter.
According to a study (2001) by the Korea Institute of Geoscience and Mineral Resources, Jeju Samdasoo is 18 years old. The Jeju Samdasoo you drink has been purified by Mother Nature for nearly two decades through her volcanic rock filters that span over 2,000 meters in distance.

Jeju Samdasoo - Perfected by Scoria and Vesicular Basalt

Above the ground and under, Jeju’s layers are abundant in scoria, clinker and vesicular basalt that are superb in filtering contaminants. Thanks to these geological features, Jeju Samdasoo has earned a reputation as pure water, free from heavy metals and other harmful substances. This is supported by a study conducted by Professor Ho-won Lee and his team from Jeju National University’s Department of Chemical & Biological Engineering, which in 2017 explored how scoria purifies contaminants. The study found that while widely-used activated carbon could not remove cadmium (Cd) completely three hours after the experiment had begun, scoria did just the opposite even after 24 hours. The study demonstrates scoria’s excellent ability to remove heavy metals.

Jeju Samdasoo - Crafted by Volcanic Rock

Because Jeju’s groundwater slowly flows through the cracks and pores of massive volcanic rocks that span over 2,000 meters, it is packed with physiologically active minerals that are healthy for you.
A paper (Gwan-pyo Koh, 2013) featured by the internationally prominent journal “Evidence-Based Complementary and Alternative Medicine” suggests that Jeju Samdasoo improves blood glucose levels in patients with diabetes. According to another study (Hiroshi Matsuda, 2014) featured by the Japanese Dermatological Association also indicated that Jeju Samdasoo improves clinical dermatitis symptoms and helps the skin to maintain its barrier functions. There are other academic studies that indicate the excellent benefits of Jeju Samdasoo. It was found that the long-term consumption of Jeju Samdasoo may boost the immune system (Young-heun Ji, 2016) and may even be beneficial to weight loss (Ho-jin Yu, 2016).

Jeju Samdasoo - Consistently Safe for 20 Years

First released as a brand in February 1998, Jeju Samdasoo has maintained the purest quality and safety through the years, certified during stringent water quality tests conducted by the US Food and Drug Administration, the Japanese Ministry of Health, Labour and Welfare, and Chinese authorities.
Since the massive earthquake that hit Japan in 2011, the Korea Basic Science Institute has conducted 75 tests on Jeju Samdasoo, looking for traces of radioactive substances and found none, proving its safety.
Jeju Samdasoo is monitored in real time with the latest automated network that covers 14 points of collection. Underground water levels, water temperature, electrical conductivity, and pH are some of the things monitored by the system every hour.

Jeju Samdasoo - The Best Water for Coffee and Tea

Minerals picked up from the interaction of water and (volcanic) rock are dissolved in Jeju Samdasoo, making it pleasant to drink. Jeju Samdasoo is soft, excellent for coffee and tea as well as in baby formula.
Jeju Samdasoo is particularly suited to green tea. Tea brewed in Jeju Water is clear and rich in healthy minerals. Coffee aficionados are keen about the rich aroma Jeju Samdasoo adds to the brew. Recently, more and more coffee and green tea enthusiasts are joining the ranks behind Jeju Samdasoo as their water of choice.

Jeju Samdasoo - Filtered Clean but Very Much Alive

Some bottled water in Korea is purified through advanced systems that use activated carbon. Because Jeju Samdasoo is naturally pure, all it needs is filtration and ultraviolet sterilization, offering natural live water instead of dead purified water.
Certified by ISO 9001, ISO 14001, US NSF(National Sanitation Foundation International) and FSSC 22000, Jeju Samdasoo is globally competitive in its production and quality assurance systems, ensuring the water’s safety and hygiene and giving you peace of mind.

Jeju Samdasoo - Korea’s Number One Brand

Sourced from layers of volcanic rock 420 meters underground, Jeju Samdasoo offers fresh water from clean Jeju through its globally competitive production and quality assurance systems.
Since its launch in 1998, Jeju Samdasoo has stayed on top, in terms of drinking water market share, customer satisfaction, and brand power.
Also, Jeju Samdasoo has maintained its status as the top Korean Brand Star by BrandStock for 13 consecutive years in the sector of spring water, and has been ranked No.1 NBCI (National Brand Competitive Index by Korea Productivity Center) for 12 years in a row, No.1 Korean Brand Power Index (by KMAC) for 12 consecutive years, and No.1 premium brand index (KS-PBI) by Korean Standards Association for 5 consecutive years, all in the sector of spring water.
