　　為保護民眾飲用水安全，環保署過去十幾年來針對淨水場水質皆有監測計畫。但淨水場水源來自不同取水口，為保護飲用水，須了解各取水口水質情況。取水口水質受到上游集水區影響，因此集水區保育是保障取水口供水安全必要措施。本計畫針對我國取水口現況，篩選出優先需管理集水區並進行污染調查。以民生用水供水量、水質達成率以及是否直接供應淨水場，篩選4處優先管理對象為：八堵、鳶山堰、石岡壩和高屏溪攔河堰取水口上游集水區。為提升污染削減成效，建議優先找出這4處集水區之污染熱區，再從污染熱區開始削減。本計畫參考國內各相關文獻報告、水質測站資料、40點次水質補充調查、SWMM模式工具應用等，分別針對這4處集水區提出各自目標達成率、目標削減量，以及可能的削減策略。此4處集水區皆符合飲用水水源水質標準，但尚未達到水體分類標準。因集水區特性，八堵與鳶山堰以點源污染為主，石岡壩與高屏溪則須加上非點源污染控制。另外本計畫全面調查4處集水區內列管事業，篩選19家風險較高事業並實際採樣10家事業放流水進行新興污染物檢測，檢測結果可與下游淨水場水質合併分析，瞭解集水區內事業放流水之新興污染物影響程度。

In order to protect safety of drinking water, the EPA monitored water purification plants for the decades. However, the water source of each purification plants are multiple and it derives a need to manage different water source quality. The water quality of water sources is depended on good upstream watershed management. Therefore, this project is aimed to investigate the priority watershed for important water intake points. The 4 investigated watershed were selected by domestic water supply quantity, water quality achievement rate, and direct to water purification plants. They are Badu, Yangshanyang, Shiganba, and Kaoping river. To increase pollution reduction efficiency, pollution hot spot, should be determined. The pollution hot spots were decided by literature review, water quality monitoring data, onsite water sampling tasks, and SWMM model. The target rate, target pollution reduction quantity, and possible reduction strategies were finally suggested for each of the 4 watersheds. The 4 watersheds have already matched the water quality standard of drinking water sources, but they did not achieve waterbody quality standard. The Badu and Yangshanyan were mainly from point pollution sources, but Shiganba and Kaoping river were influenced by both point and nonpoint pollution sources. In addition, the listed industries in the 4 watersheds were surveyed for their potential of emerging contaminants risk. Nine of the industries were further sampled and tested the POPs, environmental hormone, and heavy metals. The results of industry survey could be combined with the data of water purification plants to clarify the possible risk of emerging contaminants on public drinking water.
