Investigation of Compounds of Emerging Concern in Drinking Water and Management of Water Quality 2018

Absrtact	This project implement contaminants screening process of drinking water quality regulation. Six unregulated contaminants were selected from Universe Contaminant Candidate List. Their concentration were monitored in six representative drinking water treatment plants, and their health risk in drinking water system in Taiwan were evaluated. Monitoring results showed that these six compounds didn’t result in significant health risk in drinking water system in Taiwan. This project also collected the monitoring histories of unregulated contaminants in Preliminary Contaminant Candidate List and Contaminant Candidate List, and proposed a priority list of unregulated contaminants monitoring. In addition, this project inspected 36 unregulated compounds of emerging concern in drinking water. Results showed that 12 compounds didn’t result in significant health risk in drinking water system in Taiwan, so it is suggested to reduce monitoring frequency of these compounds or to test other compounds. For rest of 24 compounds, continuous monitoring is suggested to have more comprehensive local concentration data in Taiwan for risk evaluation. Besides, this project also review and update toxicology database of 18 drinking water quality regulation compounds (7 heavy metal, 6 pesticide, and 5 organic compounds). After collecting and review international drinking water management, this project suggested to establish annual drinking water quality reports and the database of drinking water quality measurements, and to promote Water safety Plan on a trial basis. To cooperate with administrative needs, this project collected information of the management of micro-plastics in drinking water. Since there is no standard methods for risk evaluation and analysis of micro-plastics, follow-up of development of methods among nations is suggested. Besides, this project evaluated the occasions of use of high molecular polymers. Considering the health risk from high molecular polymers, coordinate actions are highly suggested to use high molecular polymers.
