Hansung Cleantec's subsidiary EN Water announced on the 23rd that it has obtained the Laboratory of Excellence international certification as the top analysis institution for five consecutive years in the water quality field proficiency test conducted by the Environmental Resource Association (ERA) in the United States.
The international proficiency test by the Environmental Resource Association is a global certification program in which analysis institutions worldwide participate to verify their testing and analysis capabilities, allowing recognition of analysis skills and reliability that meet international standards.
The proficiency evaluation method involves analyzing samples provided by the Environmental Resource Association, converting the submitted measurement values into standard scores (Z-scores), and evaluating each category as ▲Satisfactory ▲Warning ▲Unsatisfactory.
EN Water was selected as the top institution by receiving a 'Satisfactory' rating with excellent results in all five water quality categories (BOD, TOC, SS, T-N, T-P) in the 354th international proficiency test in 2024.
Kim Hwangrae, CEO of EN Water, stated, “By obtaining the Laboratory of Excellence international certification as the top analysis institution for five consecutive years since 2020, we have demonstrated high expertise and excellence in water quality testing and analysis. We will continue to enhance our measurement and analysis capabilities to increase reliability and strive to improve the quality of public sewage treatment facility management services based on world-class water quality analysis capabilities.”
