　　本計畫主要針對全國22個直轄市及縣市行政轄區362處自來水供水系統及38處簡易自來水抽驗點進行飲用水水質中較難檢驗項目之抽驗，其分析項目包括47項列管項目及26項非列管項目，共計73項水質項目之現況背景資料。 　　列管項目包括13項重金屬（砷、鉛、硒、鉻、鎘、鋇、銻、鎳、汞、銀、銦、鉬、鋁）、1項影響健康物質（氰鹽）、4項消毒副產物（總三鹵甲烷、溴酸鹽、亞氯酸鹽、鹵乙酸類）、15項揮發性有機物（三氯乙烯、四氯化碳、1,1,1-三氯乙烷、1,2-二氯乙烷、氯乙烯、苯、對-二氯苯、1,1-二氯乙烯、二氯甲烷、鄰-二氯苯、甲苯、二甲苯、順1,2-二氯乙烯、反1,2-二氯乙烯、四氯乙烯）、13項農藥（安殺番、靈丹、丁基拉草、2,4-地、巴拉刈、納乃得、加保扶、滅必蝨、達馬松、大利松、巴拉松、一品松、亞素靈）、1項持久性有機污染物（戴奧辛）共47項。 　　非列管項目包括3項重金屬（六價鉻、鎵、鉈）、1項甲醛、6項揮發性有機物（1,1-二氯乙烷、1,2-二氯丙烷、苯乙烯、氯苯、乙苯、甲基第三丁基醚（MTBE）、2項半揮發性有機物（六氯苯、六氯環戊二烯）、3項農藥（芬殺松、甲基多保淨、固殺草）、8項環境荷爾蒙（壬基酚、雙酚A、鄰苯二甲酸二甲酯（DMP）、鄰苯二甲酸二乙酯（DEP）、鄰苯二甲酸二丁酯（DBP）、鄰苯二甲酸丁基苯甲酯（BBP）、鄰苯二甲酸二辛酯（DNOP）、鄰苯二甲酸二（2-乙基己基）酯（DEHP）、2項微生物（糞便性大腸桿菌群、大腸桿菌）、1項生物代謝產物（微囊藻毒LR型）等共26項。 　　本(105)年度計畫共完成抽驗自來水供水系統法規列管項目6,460項次及非列管項目889項次，簡易自來水則完成抽驗法規列管項目785項次及非列管項目69項次。本(105)年度自來水供水系統（含配水點）水質抽驗合格率，以抽驗點而言，整體水質合格率為98.9%(358/362)，而就抽測項目而言，整體合格率為99.9%(6,455/6,460)；簡易自來水供水系統部份，以抽驗點而言，整體水質合格率為100.0%(38/38)，而就測項而言，整體合格率亦為100.0%(785/785)。 　　本(105)年度超過飲用水水質標準之抽驗點及抽驗項目，包括新北市中幅(TTW-B13)淨水場之鋁測項、新北市石碇(TTW-B15)淨水場之鋁與鹵乙酸類測項、新竹縣關西(TTW-E04)淨水場之鋁測項，以及新竹縣關西淨水場配水點（關西鎮中山東路110號）之鋁測項，共4個抽驗點，總計5個項次；另針對104年度超標測點、臨標測點或鋁測值超過0.2 mg/L之抽驗點，本年度監測結果發現新北市中幅淨水場測值仍有超標情形，其餘測點均有明顯改善且均已符合飲用水水質標準。

　　The purpose of this project was to examine the water quality of the pre-chosen 362 drinking water systems and 38 simple tap-water systems of the 22 municipal counties or cities. There were 73 analytes for drinking water systems, with 47 of them regulated and the remaining 26 non-regulated. The regulated analytes included 13 metals (arsenic, lead, selenium, chromium, cadmium, barium, antimony, nickel, mercury, silver, indium, molybdenum and aluminum), 1 health affecting substance (cyanide), 4 disinfection byproducts (total trihalomethanes (TTHMs), bromate, chlorite and haloacetic acids (HAA5) ), 15 volatile organics (trichoroethylene, carbon tetrachloride, 1,1,1-trichloroethane, 1,2-dichloroethane, vinyl chloride, benzene, 1,4-dichlorobenzene, 1,1-dichloroethene, dichloromethane, 1,2-dichlorobenzene, xylenes, cis- and trans- 1,2-dichloroethene, tetrachloroethene and toluene), 13 pesticides (endosulfan, lindane, butachlor, 2,4-D, paraquat, methomyl, carbofuran, Isoprocarb, methamidophos, diazinon, parathion, EPN, and monocrotophos) and 1 persistent volatile organic compound (dioxins), which accounted for a total of 47 analytes. 　　The non-regulated analytes included 3 metals (hexavalent chromium, gallium, thallium), 1 formaldehyde, 6 volatile organics (1,1-dichloroethane, 1,2-dichloro propane, styrene, chlorobenzene, ethylbenzene, and MTBE), 2 semi-Volatile organic compounds (hexachlorobenzene, and hexachloro-cyclopentadiene), 3 pesticides (fenthion, thiophanate-methyl, and glufosinate-ammonium), 8 endocrine disrupting chemicals (nonyl phenols, bisphenol A, dimethyl phthalate (DMP), diethyl phthalate (DEP), di-n-butyl phthalate (DBP), nenzyl butyl phthalate (BBP), di-n-octyl phthalate (DNOP), bis(2-ethylhexyl) phthalate (DEHP)), 2 microorganisms (fecal coliforms, E. coli) and 1 biological metabolite (microcystin-LR), which accounted for a total of 24 analytes. 　　The total test counts of the regulated analytes and non-regulated analytes for tap-water systems were 6,460 and 889, and the total test counts of the regulated and non-regulated analytes for simple tapwater systems were 785 and 69, respectively. Water examined for all tested locations met the required drinking water criteria, which had a passing rate of 98.9% and 99.9%. All analytes tested met the required drinking water criteria, which had a passing rate all of 100.0%. 　　The results indicated exceed the drinking water quality standards include for aluminum of TTW-B13 in New Taipei City (Zhong-fu water treatment plant), TTW-B15 in New Taipei City (Shi-ding water treatment plant), TTW-E04 in Hsinchu County (Kan-sai water treatment plant), TTW-E04-1 in Hsinchu County (Kan-sai water distribution point: Kan-sai township), HAA5 of TTW-B15 in New Taipei City (Shi-ding water treatment plant), However, the test locations with analytes that exceeded or approached the drinking water regulatory limits of 2015, aluminum concentrations exceeding 0.2 mg/L, were followed up and re-tested in this year. The results indicated that the analytes re-tested met the drinking water quality standards except for aluminum of TTW-B13 in New Taipei City (Zhong-fu water treatment plant), which still exceeded the drinking water regulatory limits.
