107年飲用水水質抽驗計畫

中文摘要 本計畫主要針對全國22個直轄市及縣市行政轄區242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44項列管水質項目之現況背景資料。  列管項目包括11項金屬(砷、鉛、硒、鉻、鎘、鋇、銻、鎳、汞、銀、鋁)、1項影響健康物質(氰鹽)、3項消毒副產物(總三鹵甲烷、溴酸鹽、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44項。   本(107)年度計畫共完成抽驗自來水供水系統法規列管項目4,352項次,簡易自來水則完成抽驗法規列管項目540項次。本(107)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98.3%(235/239),而就抽測項目而言整體合格率為99.9%(4,348/4,352);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%(540/540)。  本(107)年度超過飲用水水質標準之抽驗點及抽驗項目,包括新北市員山淨水場(TTW-B02)之鋁(0.350 mg/L) 測項、連江縣坂里淨水場(TTW-W03)之鋁(0.798 mg/L)測項、金門縣榮湖淨水場(TTW-V02)之總三鹵甲烷(0.0842 mg/L)測項及金門縣榮湖淨水場-五龍山供水站(TTW-V02-1)之總三鹵甲烷(0.0901 mg/L)測項;另針對106年度超標測點、臨標測點之抽驗點,本年度監測結果均有明顯改善且均已符合飲用水水質標準。

A Survey of Drinking Water for Certain Specific Analytes in the Water Quality Standards

英文摘要 The purpose of this project was to examine the water quality of the pre-chosen 242 drinking water systems and 38 simple tap-water systems of the 22 municipal counties or cities. There were 44 analytes for drinking water systems.The regulated analytes included 11 metals (arsenic, lead, selenium, chromium, cadmium, barium, antimony, nickel, mercury, silver and aluminum), 1 health affecting substance (cyanide), 3 disinfection byproducts (total trihalomethanes (TTHMs), bromate 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 43 analytes.   The total test counts of the regulated analytes for tap-water systems were 4352, and the total test counts of the regulated analytes for simple tapwater systems were 540 respectively. Water examined for all tested locations met the required drinking water criteria, which had a passing rate of 98.3% 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 aluminum exceeded the drinking water quality regulations include TTW-B02 which is one the distribution network of Yuan Shan water treatment plant in New Taipei City, TTW-W03 (Ban Li water treatment plant) in Lienchiang County; the content of Total Trihalomethanes (TTHMs) exceeded the drinking water quality regulation include TTW-V02 (Rong Hu water treatment plant) in Kinmen County, TTW-V02-1 (Wu Long Shan points of distribution) in Kinmen County. Focusing on concentration which exceed and approach the drinking water regulation in 2017, the results show that all of the test location had improved since 2018.
