  • Conducting surveys and research on emerging environmental issues in each watershed in order to preserve a healthy water environment
  • Operation of national monitoring network for water quality and sediment to support policies responding to climate change
  • Measuring mainstream and tributary flows for promotion of a total maximum daily load (TMDL) management system
  • Operation of a monitoring network for radioactive substances in public waters for management of a safe water environment
  • Water quality measurement with preventive measures through algal bloom alarm systems
  • Monitoring the aquatic ecosystem at weirs in the four major rivers
  • Operation of a monitoring network for Norovirus in drinking water during drought periods in areas lacking water
  • Operating UNEP GEMS/Water Program for national water quality basic data
  • Conducting detailed surveys on nonpoint sources and rivers by watershed
