中文摘要	本計畫為因應土壤及地下水污染飲用水水質事件，及為更周全保障飲用水的安全，故急需檢討作為人使用地下水為飲用水水源時，其飲用水水質之揮發性有機物管制項目，並建議修訂之必要性的管制項目與合理管制標準，主要研究之項目包括：苯（Benzene）、1,2-二氯苯(1,2-Dichlorobenzene)、1,1-二氯乙烷（1,1-Dichloroethane）、1,1-二氯乙烯（1,1-Dichloroethylene）、1,2-二氯丙烷(1,2-Dichloropropane)、乙苯（ethyl benzene）、甲基第三丁基醚【Methyl-butyl ether (MTBE)】、四氯乙烯(Tetrachloroethylene)、甲苯(Toluene)、三氯乙烯（Trichloroethene）、順-1,2二氯乙烯（Cis-1,2-Dichloroethylene）、苯乙烯(Styrene)、氯乙烯（Vinyl chloride）、二甲苯(Xylenes, total)等14種標準性有機物。本計畫已彙整世界衛生組織、歐盟、美、日、英、澳、加國家地下水中揮發性有機物管制現況，及國內污染場址中及周界地下水，及鄰近之其他水源中揮發性有機物流布資料。並已針對國內9處污染場址鄰近民井地下水以及鄰近之5處自來水、10處簡易自來水水源中揮發性有機物進行流布資料，執行完成71個水樣中14種揮發性有機物檢驗工作。流布調查成果發現，部分污染場址鄰近非供人飲用民井部分水樣確有揮發性有機物之存在，而在45個自來水淨水廠及簡易自來水設施水樣中，僅3個測得揮發性有機物之樣品，而其檢測值遠低於我國現行地下水污染管制標準或美國環保署之飲用水水質標準。在所有樣品中，共60個水樣所有14種揮發性有機物檢測值低於偵測方法極限。本計畫並已彙編與評析完成14種飲用水中揮發性有機物管制項目之影響健康毒理等基本資料。並邀集學者專家及業界代表完成三次研商會，對增列飲用水中揮發性有機物管制項目可行性，及研擬地下水中揮發性有機物具體管制策略，進行充分討論。本計畫使用「多介質環境污染評估系統」套裝軟體計算地下水中揮發性有機物之健康風險，對標的有揮發性有機物進行致癌及非致癌性分析。綜合風險評估成果與現有毒理資料，並考量國內檢測方法已公布，供水業者也可負擔檢測成本的情形下，考量部分揮發性有機物國內用量極大，且污染場址中曾有測得其分布，並曾發生非法棄置或洩漏污染飲用水案件等種種因素考量之後，本計畫依我國地下水污染管制標準、世界衛生組織、美、日、澳等標準，建議飲水中增加四氯乙烯、二氯甲烷、甲苯、乙苯、順、反1,2-二氯乙烷等 6種揮發性有機物管制優先列管，另有8種揮發性有機物管制建議未來分階段逐步列管。在管制策略方面，建議於污染飲用水事件發生時。於可能受影響地區加強監測，以保障民眾健康及去除疑慮。平日一般淨水廠則無須監測，以節省水廠成本。而飲用水井管理方面，則加強宣導及查察，並參考日本的制度進行公告及管理。本計畫亦建議比照美國及日本作法精神，於檢討中及可能列管之有機物進行背景監測調查。

摘要	To manage risks form soil and groundwater pollution incidents, and to enhance drinking water protection, this project evaluate the necessity for 14 volatile organic compounds (VOC) to be regulated or to be re-evaluated in ROC drinking water regulations in groundwater served as drinking water sources. Studied volatile organic compounds included Benzene, 1,2-Dichlorobenzene, 1,1-Dichloroethane, 1,1-Dichloroethylene, 1,2-Dichloropropane, ethyl benzene, Methyl-butyl ether (MTBE), Tetrachloroethene, Toluene, Trichloroethylene, Cis-1,2-Dichloroethylene, Styrene, Vinyl chloride and total Xylenes. For VOC, this study summarized drinking water protection measures and maximum contaminant levels of WHO, EU, USA, UK, Japan, Australia, and Canada. In addition, historical data for domestic VOC investigation in contaminant sites were also reviewed. To establish background information for current domestic VOC distribution, this study measured 14 VOC’s concentrations of 71 samples from 9 wells within or neighboring contaminant sites, 5 major drinking water treatment facilities and 10 on-site drinking water treatment facilities. VOCs were found existed in ground water samples from certain wells, for non-drinking water supply, within or neighboring contaminant sites. In 45 samples from 5 major drinking water treatment facilities and 10 on-site drinking water treatment facilities, very low concentrations of VOC’s were detected in just three samples, in addition, the above detected concentrations were barely above detection limit and much lower than USEPA or other existed guideline values. Overall, the detected values of 60 samples were below detection limits for studied VOC’s. In combination with risk analysis conducted in this study, we recommended to regulate 6 VOC’s, including tetrachloroethylene, ethyl benzene, toluene, trans and cis-1,2-dichloro ethylene, according to guideline values of WHO, USEPA, Australia and Japan. This study also suggested regulation for eight other VOC’s in next phase for near future.
