Natural Mineral Water

Protection Effects of G-H Lens

Jeju-do is an island created by over 300 volcanic eruptions that took place during the 3rd and the earlier part of the 4th period of Cenozoic Era. It consists with scores of layers of basalt lava erupted in the course of volcanic activities. Such geographical structure displays characteristics to develop groundwater due to water permeability of surface of the earth rather than surface waters to form rivers and water streams.With the annual rainfall of 1,975mm, Jeju-do records the highest level of rainfall in Korea. 46% of the total rainfall permeates underground, thus forms the groundwater resources of Jeju-do. According to experts' research, the volume of these groundwater resources is estimated to be approximately 70 billion tons or more. The vast quantity of groundwater in Jeju-do displays the following characteristics as caused by the typical geological and topographical features of this region.


Characteristics of Resource Form
Most of groundwater in Jeju-do is underlying water or its equivalent. As a result, it exists in the lens form at a considerable depth from the sea level due to the difference in specific gravity between the fresh and seawater.

Jeju Samdasoo is the heaven-blessed water protected by 'G-H Lens'.
Samdasoo Water Pocket, the Mysterious Fort Protected by G-H Lens- Groundwater floats underneath the sea level in the lens form due to the reaction of natural osmotic pressure and is protected by the sea from inflows of inland pollutants. Therefore, Samdasoo Water Pocket is in fact a gigantic water tank surrounded by a type of 'natural pollution prevention walls'. Such a mysterious phenomenon can also be found in Hawaii. Especially, Jeju-do is well known to have very favorable topographic conditions.


Characteristics of Water Quality
The weak alkaline groundwater neutralizes acidification and prevents aging of cells. The groundwater of Jeju-do is healthful water of good and soft taste because of its low mineral content and the extremely low level of hardness.

Characteristics in accordance with the Peculiarity of Geological Stratum
Consisted of porous lava, the geological stratum enables self-purification of rainwater as it permeates underground level. In particular, black volcanic ash contained in the soil displays strong pollutant absorption effect, which is no inferior to that of active carbon used as water purifier. This property enables to maintain clean water quality.

It is safe water with no compounds harmful to human body.
In general, properties included in water as compounds harmful to human body are arsenic, fluorine and nitrate nitrogen, etc. The results of analysis performed on inorganic substances by FDA of US indicated that ‘Jeju Samdasoo’ is safe water with no or very low levels of harmful substances detected.

'Jeju Samdasoo' is free from seawater pollution.
Jeju-do is in a close proximity to seawater. For this reason, the greatest concern in relations to inorganic substances is the concentration of chlorine ions, which indirectly indicates seawater pollution. The concentration of chlorine ions in ‘Jeju Samdasoo’ is 5∼6㎎/ℓ, thus does not display a large difference from the concentration level in other spring waters. As such, ‘Jeju Samdasoo’ is pure groundwater of no seawater pollution obtained from Mt. Halla.

Safe water pumping environment with no inflows of night soils and polluted/ wastewater.
With concentration of nitrate ions, the indicator of pollution by night soils and polluted/ wastewater, being 0.3∼0.4㎎/ℓ, ‘Jeju Samdasoo’ was found to contain absolutely no volatile organic substances. This proves that the water pumping environment is safe and free from any pollution generation facilities of factories and livestock farming facilities in the surrounding region.

Safe water free from the pollution of radioactive materials
By securing a location free from the pollution of radioactive substances due to its topographical and geological features of volcanic mountain, ‘Jeju Samdasoo’ is safe from the recently raised issue of radioactive pollution in groundwater. In reality, concentrations of Gross Alpha, Gross Beta and Radium, the indices of radioactive pollution, were found to be very low or not detected at all. As such, ‘Jeju Samdasoo’ to display no detection or detection level of below the FDA standards in all items of radioactive substances, chemicals, organic compounds, pesticides and heavy metals is one of the safest dinking water products offered.

JEJU Sam Da Soo

‘Jeju Samdasoo’ is groundwater obtained from volcanic aquifers located 420m deep in Mt. Halla, the national park of international recognition. Not only the taste of very refreshing and light, but also the quality is uniformed. Due to the natural self-purification characteristics unique to volcanic layer, water quality is very pure and clean. Jeju Samdasoo has satisfied the water quality test standards of FDA of US and Japanese Ministry of Welfare, thus has been recognized of its outstanding quality throughout the world. In order to maintain and control clean environment and safety of water quality, environmental watch and regular inspection is carried out on the status of changes in ecosystem and occurrence of pollutants in the surrounding areas of the pumping well. Professional experts and a variety of experimentation/ analysis devices have been secured to supply our customers with clean and fresh products containing the purity of nature, thus to actively respond to quality and hygiene management of the products. Jeju Provincial Development Corporation administers regular quality inspections to maintain and control the safety of water quality in protecting the health of our customers. We are also requesting water quality analysis each year on the basis of standard tests from nationally certified organizations, FDA of US and Japanese Ministry of Welfare to secure the safety of our water.

To supply products trusted by our customers, Jeju Provincial Management Corporation is enforcing strict quality management system per each production process. Details of quality management per each process are as of the following.
