Jangnim Reservoir Research Featured in the News
Oct 23, 2026
Yonhap News and Asia Economy feature our Water paper on water quality improvements at Jangnim Reservoir in Busan.
Our research on the Jangnim Reservoir environmental improvement project in Busan has been featured in [Yonhap News](https://www.msn.com/ko-kr/news/other/부산-장림유수지-환경개선사업으로-수질개선-뚜렷/ar-AA2fSeB7) and [Asia Economy](https://www.asiae.co.kr/article/2026102310475609717).
Our paper in Water (https://doi.org/10.3390/w18172127) analyzed public water quality data from 2020 to 2025 to assess changes following the installation of a multistage vortex aeration system. Key findings included:
72.4% increase in dissolved oxygen
41.2% reduction in total nitrogen
59.6% reduction in total phosphorus
The findings highlight progress in oxygen conditions and nutrient reduction, while emphasizing the need for continued pollution control to support lasting restoration.
We hope this news coverage helps the local community learn more about the project's achievements and how research supports efforts to improve our shared water environment.
