中文摘要	近年來環保署致力於含氯碳氫化合物污染場址之鑑識技術開發，提升國內環境鑑識領域之能量，然而，成功的環境鑑識須搭配足夠的調查資訊，為了掌握含氯碳氫化合物污染分布情況，以利科學數據之判讀與鑑識之執行，本計畫以發展含氯碳氫化合物污染場址污染來源高解析場址調查技術為主要目標，並將過去建置的環境鑑識技術應用到國內污染場址，同時，評估地下水定年法作為污染物洩漏年代之適用性。本計畫所建立的高解析場址調查技術包含「井內薄膜介面感測器」、「連續式微洗井」、「即時探測污染設井法」，主要功能為提供污染物垂直向濃度分布資訊，以建構更仔細的場址概念模型，將各技術與公告方法(「多深度擴散式採樣袋」或「井叢貝勒管」)的應用成果進行對照，顯示本計畫所建立的高解析場址調查技術具有(1)可與動態工作策略搭配；(2)可運用於礫石地質；(3)迅速且經濟，以及(4)提供可靠且高密度數據等優點。此外，本計畫亦完成國內 189 處含氯碳氫化合物污染場址之盤點，針對其中 30處具潛在鑑識需求之場址，提出調查及鑑識工作建議，並從中篩選 4 個場址，運用過去建置的環境鑑識技術與新建立的高解析場址調查技術，提供有助於污染關聯性及污染來源調查之相關資訊，供環保署及環保局參考；再將歷年調查與技術應用經驗，撰寫成「土壤及地下水含氯有機物污染來源調查技術參考手冊 - 高解析度場址調查策略與技術運用」。在污染洩漏年代定年法評估方面，本計畫優先選擇氟氯碳化合物定年法為評估對象，並篩選出兩場址進行應用，評估結果顯示氟氯碳化合物定年法容易受到人類活動(例如：壓縮機冷媒)和厭氧脫氯等干擾，欲應用在國內場址，須審慎評估場址條件是否合適，若有定年必要，建議可考慮較不受人為影響的氚氦定年法，但氚氦定年法之樣品培養與分析較費時，規劃時應將所需時間納入期程規劃。

摘要	Recently, Environmental Protection Administration Executive Yuan, R.O.C (Taiwan) contributed to developing environmental forensic technologies for chlorinated contaminated sites, and then improve domestic environmentalforensic abilities. However, a successful forensics needs enough investigation information. In order to get the profile of chlorinated contaminants distribution, that is beneficial to scientific data interpretation and forensics conducting, this project had one major purpose and two minor goals. The main purpose was to develop high-resolution site characterization (HRSC) technologies for source identification of chlorinated ethenes (CEs) sites. And then, one minor goal was to apply environmental forensic technology that had been developed on site investigations. Another one was to evaluate the feasibility of chlorinated contamination release age dating by groundwater dating technology. There were three HRSC technologies established in this project. The first one was "In-well Membrane Interface Probe (In-well MIP)". The second one was "Continuous Micro-Purge Water Sampling (CMPWS)", and the last one was "Immediately Analyzing Contamination during Well-Installation (IACWI)". All of them could offer the vertical concentration profiles for setting up a detailed conceptual site model (CSM). The application results of those new technologies were compared with that of announcement methods ("Polyethylene Diffusion Bag Samplers" and "Well cluster with bailer sampling"). Results showed that those three new technologies could 1) cooperate with dynamic decision-making; 2) be applied on sites with gravel; 3) be more economical and faster; and 4) offer reliable and high-density data. Additionally, this project checked situations of 189 domestic CEs sites. For 30 sites that might need forensic investigation, we offered investigation and forensic suggestions. And then, 4 sites were picked up from them to apply environmental forensics and new HRSC technologies, and offer information about sources identification and source relationship identification to Environmental Protection Administration and Environmental Protection Bureau. According to the above results and previous investigation experiences, "Soil and Groundwater Chlorinated Organic Compounds Source Identification technologies Guide " was compiled. Finally, the feasibility of chlorofluorocarbons (CFCs) Age-dating techniques used to estimate the contaminant release age was evaluated. Results showed that CFCs age-dating techniques were impacted by human activities easily. If we want to apply this technique to get the contamination release age, the conditions of the site must be evaluated in advance. In addition, tritium- helium dating techniques was another method which was not easily impacted by human activities. However, the duration of tritium-helium sample analysis was very long. It must be considered into the investigation schedule.
