The Gyeonggi Institute of Health and Environment has been selected as an outstanding analytical institution in the field of water quality.

On April 29, the Gyeonggi Institute of Health and Environment announced that it had been recognized as an outstanding analytical institution in the water quality sector of the "2026 Domestic and International Proficiency Test," having received a "satisfactory" evaluation in all categories.

The proficiency test is a system in which multiple institutions analyze the same unknown sample and compare the results to evaluate testing and analytical capabilities. The domestic proficiency test is managed by the National Institute of Environmental Research for environmental pollution inspection agencies, while the international proficiency test is overseen by the U.S. Environmental Resource Associates (ERA) and involves analytical institutions from around the world.
