Title 飲用水水質標準中較難檢驗項目抽驗計畫
Abstract 本計畫主要針對25個行政區164個自來水供水系統及26個簡易自來水檢測點進行飲用水水質中較難檢驗項目之抽驗，其分析項目包括重金屬(砷、鉛、硒、鉻、鎘、鋇、銻、鎳、汞、銀)、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)、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)、氟鹽、總三鹵甲烷(三氯甲烷、二氯一溴甲烷、一氯二溴甲烷、三溴甲烷)，共計33項水質項目。本年度針對各供水系統之需求不同，各縣市檢測點之規劃略有差異，其中自來水供水系統方面，包括宜蘭縣等13個縣市，每一縣市篩選8個檢測點，計有104個檢測點，檢測項目(含農藥)計有33項，其餘12個縣市，每一縣市篩選5個檢測點，計有60個檢測點，檢測項目(未含農藥)計有20項，而簡易自來水，包括宜蘭縣等10個縣市，每一縣市篩選2～4個檢測點，計有26個檢測點，檢測項目(未含農藥)計有20項。本年度監測結果發現，自來水供水系統之抽驗點中自來水供水系統之抽驗點中揮發性有機物(三氯乙烯及1,1-二氯乙烯除外)及農藥(巴拉刈除外)等18項，以及簡易自來水之抽驗點中揮發性有機物(四氯化碳除外)等12項之檢測結果皆為ND。至於水質抽驗合格率，以縣市而言，各抽驗點之水質合格率為100.0％，而就抽驗點而言，各分析項目之檢測點合格率為100.0％。
EngTitle A survey of drinking water for certain specific analytes in the water quality standard
EngAbstract The purpose of this project is to examine the water quality of the pre-chosen 164 drinking water systems and 125 simple tap-water systems of the 25 municipal counties(or cities). The items being tested include heavy metals (As, Pb, Se, Cr, Cd, Ba, Sb, Ni, Hg, Ag), volatile organics (trichoroethylene, carbon tetrachloride, 1,1,1-trichloroethane, 1,2-dichloroethane, vinyl chloride, benzene, 1,4-dichlorobenzene, 1,1-dichloroethene), pesticides(Endosulfan(I & II), Lindane, Butachlor, 2,4-D, paraquat, methomyl, carbofuran, MIPC, methamidophos, diazinon, parathion, EPN, monocrotophos), fluoride and THMs , a total of 33 items.This year, the systems to be tested were chosen in accordance with the demand of each water system. In 13 municipal counties (cities) including Yilan County, eight systems were selected in each municipal county (city), a total of 104 systems were tested for 33 items. Five systems were selected for testing from each of the rest 12 municipal counties (cities). A total of 60 systems were tested for 20 items which did not include pesticides. The simple tap-water systems in 12 municipal counties (cities) including Yilan county were tested for 20 items as well. Two to four systems were selected in each municipal county for the test. A total of 26 systems were tested.The analytical results indicates that most of the analytes were found to be not detected in the drinking water systems except very low concentrations of trichoroethylene, 1,1-dichloroethene and paraquat were detected in some systems. All of the analytes were found to be not detected in the simple tap water systems except trace carbon tetrachloride were found in one system. The results indicated that all water tested met the current drinking water quality standards.
