本計畫依據飲用水列管物質篩選作業原則，自初步蒐集清單中篩選優先進行監測評估之物質，選定鈹、硼、鈷、嘉磷塞、全氟辛烷酸、全氟辛烷磺酸、大腸桿菌與糞便性大腸菌群等，於六座代表性採樣淨水場進行監測，結果顯示鈹、鈷、硼、嘉磷塞、全氟辛烷磺酸、大腸桿菌與糞便性大腸菌群等於我國飲用水中暫無顯著之風險。然六處淨水場原水或清水曾檢出微量全氟辛烷酸，建議持續監測以瞭解臺灣飲用水中全氟辛烷酸之存在情況。本計畫執行飲用水列管物質篩選作業，更新初步蒐集清單及蒐集清單，提出１０５年觀察清單物質碲、雙酚Ａ、鉈、１，２-二溴乙烷，並修正「行政院環境保護署飲用水列管項目篩選作業原則（草案）」及「我國飲用水水質未列管污染物監測作業計畫（草案）」。針對１６項現行飲用水水質標準中有關農藥、揮發性有機物質以外之影響健康物質之管理方式及管制限值進行檢討，建議除鎳、汞、亞氯酸鹽之外的項目，管制標準暫無修正之必要。本計畫亦檢討現行飲用水水質標準第四條以及酚類的管理方式。最後本計畫提出「飲用水水源水質指引」草案，及飲用水水源水質指引項目及指引值。然經專家諮詢會議結論為，「飲用水水源水質指引」之法源修正建議，涉法源修正，建議可再另案研究評估。

This project followed “contaminants screening process of drinking water quality regulation” to select compounds for monitoring and evaluation. Eight contaminants, beryllium, boron, cobalt, glyphosate, perfluorooctanoic acid, perfluorooctane sulfonic acid, fecal/thermotolerant coliform, and E. coli were selected to be monitored in six representative drinking water treatment plants and evaluated their risk in drinking water in Taiwan. The result showed that there was no significant healthy risk in drinking water from beryllium, boron, cobalt, glyphosate, perfluorooctane sulfonic acid, fecal/thermotolerant coliform, and E. coli. However, PFOA was detected in some raw water and finished water samples and was suggested to be monitored closely to determine the risk in drinking water. This project conducted “contaminants screening process of drinking water quality regulation” and modified the frame of it, referring to the unregulated contaminant monitoring rule of US EPA. Monitoring plan of universe contaminant candidate list was suggested to collect the occurrence information in Taiwan. The information will use to evaluate if a contaminant should be included into contaminant candidate list or not. Besides, this project also reviewed the regulation of phenols, substances that impact health (except volatile organic compounds and pesticide), and the Article 4 of drinking water quality standard. It was suggested that the standard of substances that impact health (except volatile organic compounds and pesticide) were reasonable, expect nickel, mercury, and chlorite. So it was not necessary to modify the standard for those substances, expect nickel, mercury, and chlorite. Finially, this project proposed to substitute the “Drinking water source water quality standard” by “Drinking water source water quality guideline”. However, the expects meeting suggested to evaluate this change with an independent project.
