　　本計畫主要針對國內25個直轄市及縣市行政轄區364個自來水供水系統及36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；簡易自來水另含銦、鉬)、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)、氟鹽、陰離子界面活性劑(僅自來水系統)、總三鹵甲烷，共21～22項水質項目。 　　98年度監測結果發現，自來水供水系統之抽驗點中四氯化碳、1,1,1-三氯乙烷、1,2-二氯乙烷、苯、對-二氯苯等5項，以及簡易自來水之抽驗點中三氯乙烯、1,1,1-三氯乙烷、1,2-二氯乙烷、氯乙烯、苯、對-二氯苯等6項之檢測結果皆為ND，本年度重金屬因全部改以ICP-MS進行分析，偵測極限較歷年為低，故檢出頻率較往年為高。本年度水質抽驗合格率，以縣市而言，除雲林縣TTW-J09(虎尾淨水場)、連江縣TTW-W04(勝利淨水場)等測點之水質合格率為95.2%外，其餘各檢測點之水質合格率皆為100.0%；而就抽驗點而言，除氯乙烯、總三鹵甲烷等項之檢測點合格率為99.7%外，其餘各分析項目之檢測點合格率皆為100.0%。

　　The purpose of this project is to examine the water quality of the pre-chosen 364 drinking water systems and 36 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 ; In, Mo only tested at simple tap-water systems), volatile organics (trichoroethylene, carbon tetrachloride, 1,1,1-trichloroethane, 1,2-dichloroethane, vinyl chloride, benzene, 1,4-dichlorobenzene, 1,1-dichloroethene), fluoride, MBAS (only tested at drinking water systems) and THMs , a total of 21 to 22 items. 　　The analytical results indicates that most of the analytes were detected in some drinking water systems except carbon tetrachloride, 1,1,1-trichloroethane, 1,2-dichloroethane, benzene and 1,4-dichloro- benzene were found to be not detected in the systems. Most of the analytes were found in some simple tap water systems except trichloroethylene, 1,1,1-trichloroethane, 1,2-dichloroethane, vinyl chloride, benzene and 1,4-dichlorobenzene were found to be not detected in these systems. This annual, because of heavy metals detected by ICP-MS, detection limits were lower than ICP-OES, and so detected frequency was higher than past years. The results indicated that only one value of vinyl chloride at one site(TTW-J09) of Yun-Lin county and one value of THMs at one site(TTW-W04) of Lien-Chiang county which did not meet the regulation, the test results for rest of the items all in compliance which the drinking water quality standards.
