Ⅰ. Background and Aims of Research
o The issue that the criteria for determining whether the pollutant level exceeds the water quality standard, which is measured by the Water-TMS (Tele-Monitoring System) in real time are one of the main causes of water data manipulation and the excessive regulations has been raised.
o Although water quality measurement values ooof treated sewage and wastewater in Korea are generated in real time by the Water-TMS, they are not used in the total water pollution management system, and the criteria for determining whether the discharge standards have been exceeded are different, causing confusion for treatment facility operators and the lack of consistency in water pollutant management policy.
o Therefore, this study aims to review the adequacy of the current criteria for determining whether water pollutants monitored by the Water-TMS in real time meet the water quality standards, and to suggest measures for the improvement of the current criteria and a linkage with the TPLMS (Total Water Pollution Load Management system).

Ⅱ. Research Materials and Methods
o This study analyzed the current status of sewage and wastewater treatment facilities, treatment facilities subject to the Water-TMS installation using wastewater related statistics and reviewed the status of policy implementation and legal system in Korea and abroad.
o The distribution of treated wastewater effluent measured in the year 2019 was analyzed for all sewage and wastewater treatment facilities with the Water-TMS based on six scenarios of the criteria for wastewater effluent s
