河川水體污染源鑑識作業程序建置與實例應用（3/3）
| 中文摘要 | 本計畫針對後龍溪、北港溪、急水溪、阿公店溪潛在污染排放源及河川水體污染物進行採樣檢測，以了解潛在污染源污染特徵及應用數值模式進行河川水體污染源鑑識之可行性。計畫執行前先詳細規劃環境污染調查方案，包含事業污染源及水體河川採樣分析計畫，並協調實際執行四條河川環境水體採樣及檢測團隊之操作與進度，產出以化學成份分析為主體之潛在污染源排放水及河川水體水質檢測資料。同時搭配本計畫執行期間蒐集研析之污染源種類與特性資訊，透過多變量分析結合質量平衡法，鑑定水體之主要污染來源並評估不同污染源之個別貢獻量。計畫執行亦規劃並擴大辦理計畫成果推廣研習，透過執行團隊及環保單位人員雙向交流，協助強化相關單位與人員的專業知能。 本期執行完成規劃兩梯次事業廢水與河川水體共計30個製程、67個排放水、245個河川水體樣品之採樣工作，並陸續協助規劃完成河川水體之52種元素、SVOC (半揮發性有機化合物)、離子、新興污染物之檢測分析。取得檢測數據後，透過統計分析了解事業廢水成份中具污染源特性之特徵元素，結合污染源指紋圖譜資料，藉由受體模式，進行河川水體重要潛勢區之污染源鑑識與貢獻量推估工作。 本計畫彙整相關檢測資料進行收斂分析，產出：1. 針對四條目的河川推導可能污染來源與後續執行污染源鑑識工作的相關建議。2. 後續可透過更多的採樣分析數據，展開更細緻的鑑識模式解析，對河川水體與事業之高濃度污染物的主要來源進行評估，以提供相關政府部門進行後續污染物減量與管控的參考。3. 根據本計畫執行結果與現場實地場勘與採樣之經驗，提出污染源鑑識操作實作規範與建議，以提供後續污染源鑑識計畫之應用。 | ||

Project of river water pollution source identification formation and practice (3/3)
| 英文摘要 | This project attempted to investigate spatial and temporal distributions of water pollution sources and their impacts on the river water quality. River Water samples were collected from selected sites at the Houlong river, Beigang river, Jishui river, as well as Agongdian river. Source profiles were obtained from sampling and analysis of industrial waste water. Source contributions to river water were estimated by statistical and modeling analysis. An advance training course and a practical workshop were completed to serve the purpose of river-pollution-source-identification skill cultivation. It also enhanced the experience sharing between departments. The works of this project were summarized as follows: (1) Literature review: analytical results of pollutants in river water, water pollution source profile, and application of source apportionment models were reviewed and summarized; (2) Sampling and analysis of industrial waste water: a total of 97 wastewater samples from 67 effluent discharges and 30 manufacture unit discharges were collected and analyzed; (3) Characterization of industrial waste water: specific markers of industrial waste water were identified; (4) Sampling and analysis of river water: a total of 342 water samples were collected from the upstream and downstream areas of the potential pollution sources in two phases, followed by analyses of 52 heavy metals and varies organic compounds; (5) Spatial and temporal distributions of pollutants in river water: temporal variations of pollutants were observed at a selected site in each river, which was identified as the most polluted hotspot; (6) Source apportionment of river water pollutants: the percent mass accounted for measured mass (%MASS) were calculated during the monitoring periods. Potential sources of pollutants, including heavy metals, and their possible locations were estimated for further investigation; (7) Modified the guideline for source apportionment of water pollution that was drafted last year for future applications. | ||
