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，其分析項目共48項列管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）、2項影響健康物質（氰鹽、氟鹽）、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48項。 　　本(106)年度計畫共完成抽驗自來水供水系統法規列管項目6,741項次，簡易自來水則完成抽驗法規列管項目675項次。本(106)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，抽驗水質合格率為99.2%(359/362)，而就抽測項目而言整體合格率為99.9%(6,737/6,741)；簡易自來水供水系統部分，以抽驗點而言，抽驗水質合格率為100%(38/38)，而就抽測項目而言整體合格率亦為100%(675/675)。 　　本(106)年度超過飲用水水質標準之抽驗點及抽驗項目，包括澎湖縣成功淨水場-湖西鄉配水點(TTW-U01-1)之總三鹵甲烷(0.0987 mg/L)測項、連江縣勝利淨水場(TTW-W04)之鋁(0.385 mg/L)與總三鹵甲烷(0.0804 mg/L)測項、連江縣儲水沃淨水場(TTW-W05)之鋁(0.309 mg/L) 測項，總計4個項次；另針對105年度超標測點、臨標測點之抽驗點，本年度監測結果發現連江縣勝利淨水場(TTW-W04)重金屬鋁仍有超標情形，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 48 analytes for drinking water systems.The regulated analytes included 13 metals (arsenic, lead, selenium, chromium, cadmium, barium, antimony, nickel, mercury, silver, indium, molybdenum and aluminum), 2 health affecting substance (cyanide, fluoride), 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 48 analytes. 　　The total test counts of the regulated analytes for tap-water systems were 6741, and the total test counts of the regulated analytes for simple tapwater systems were 675 respectively. Water examined for all tested locations met the required drinking water criteria, which had a passing rate of 99.2% and 99.9%. All analytes tested met the required drinking water criteria, which had a passing rate all of 100.0%. 　　The results indicated the content of Total Trihalomethanes (TTHMs) exceeded the drinking water quality regulations include TTW-U01-1 which is one the distribution network of Cheng Kung water treatment plant in Penghu County, TTW-W04 (Sheng Li water treatment plant) in Lienchiang County; the content aluminum of exceeded the drinking water quality regulation include TTW-W04 (Sheng Li water treatment plant) in Lienchiang County, TTW-W05 (Chuis Hui Wo water treatment plant) in Lienchiang County. Focusing on concentration which exceed and approach the drinking water regulation in 2016, the results show that the aluminum concentration of TTW-W04 (Sheng Li water treatment plant) still exceed the drinking water regulation. The rest of the test location had improved since 2017
