Jeju Development Corp. water quality analysis ranks globally highest for 8th consecutive year

Jeju Development Corporation's (JDC) water research organization has once again demonstrated its world-class capabilities, securing the highest global rating in water quality analysis for an unprecedented eighth consecutive year. This consistent achievement underscores the accuracy and reliability of its water treatment technologies.

The institute, responsible for the production and distribution of Jeju Samdasoo, participated in the 2026 International Proficiency Testing for Drinking Water, organized by the Environmental Resource Institute (ERA) in the United States. It successfully passed all 10 key tasks in physicochemical composition, maintaining its streak of global recognition since 2019.

The long-term acquisition of top domestic and international ratings is a testament to the academic proficiency and analytical capabilities of our researchers in nurturing clean drinking water.

Domestically, the research team also excelled in the annual drinking water tests administered by the National Institute of Environmental Research, an agency under the Ministry of Environment. The institute achieved satisfactory results across all 11 categories, including one type of harmful microorganism, five types of organic heavy metals, and five basic chemical items. This marks five consecutive years of meeting stringent national standards, proving its comprehensive inspection capabilities.

Kang Seong-hoon, acting president of JDC, attributed these sustained high-level domestic and international recognitions to the academic proficiency and analytical skills of the researchers dedicated to maintaining the purity of drinking water. He pledged to continuously improve the quality control capabilities to ensure consumers can drink the product without concern, aligning with its reputation. Currently, the water research lab is equipped with advanced analytical instruments and fosters continuous internal talent development, operating a complete, integrated inspection system from raw water intake to the final product.
