To ensure the safety of drinking water for the public, the Ministry of Environment has implemented monitoring programs for water quality in water treatment plants over the past decade. However, since water sources for these treatment plants come from different intake points, it is crucial to understand the water quality at each intake point to safeguard drinking water. The water quality at intake points is influenced by the upstream watershed, making watershed conservation a necessary measure to ensure the safety of water supply at intake points. This project builds upon the research results from the year 111 and focuses on four priority management locations: Badu, Yuanshan Weir, ShiGang Dam, and Gaoping River Weir, planning pollution reduction measures in their upstream watersheds.Based on the current conditions of the watershed at each intake point, the project plans on-site treatment facilities and pollution reduction strategies that meet the specific conditions. The project conducts an inventory of the water quality of 162 surface water sources in Taiwan Water Corporation's water treatment plants for COD, TOC, and ammonia nitrogen over the past five years. The achievement rate of water quality standards for drinking water sources reaches an impressive 99.0-100%.By pairing water treatment plants, intake points, and EPA water quality monitoring stations, the project statistically analyzes the achievement rates of water quality for 21 treatment plants and proposes plans for water quality improvement. Additionally, the project completes the detection and analysis of 35 emerging pollutants in 13 regulated industries. It compiles management strategies for emerging pollutants in industrial wastewater from overseas, providing measures that water supply authorities and water supply companies can adopt.
