本計畫主要針對大漢溪、基隆河、客雅溪(含三姓公溪及海山漁港)、朴子溪、將軍溪、典寶溪、高屏溪及新城溪流域進行河川水體與底泥之基本性質調查及分析水體與底質之污染物含量，並進行包括螺、貝類及底棲生物等之種類及族群分佈調查，建立相關生物圖鑑資料，同時應用統計方法探討污染物的污染潛能與可能的污染來源，以提供河川污染管理之參考。藉由流域污染程度評估，來瞭解河川環境水體之背景現況，其中水體品質部分參考河川污染指標(RPI)，底質部分引用美國紐約州環保局之重金屬危害評估等級，以最低影響標準及嚴重影響標準作為污染認定之準則，並參考美國環保署之底質污染風險評估基準，針對底質污染情形對水生生物及人體健康造成危害之影響程度，作進一步的評估，生物部分則利用魚類及大型甲殼類、水棲昆蟲(Shannon 種岐異度指數)作為指標生物來判斷水質階級。同時利用多變數統計分析方法，瞭解河川水體環境因子與生物群聚之相關性，以及時間與空間之變異性。針對各測站之水質、底質與生物調查等監測結果，進行污染區段等級區分，訂定各河段之指標物及指標生物，作為後續監測之參考依據。

The main purpose of this project is to investigate the background information for the water and sediment of Da-Han River, Kee-Lung River, Ke-Ya River, San-Xing-Gong River, Yan Shuei Harbor, Pu-Tz River, Jiang-Jun River, Dian-Bao River, Kao-Pin River, Xing-Cheng River, and to analyze the concentration of pollutants in the river water and sediment. These investigations also include findings of the distribution and varieties of conches in the area, and a biological graphic illustration is established. A statistical method is used to study the potential effects of pollution and most probable pollution sources; these findings can serve as a guideline for the oversight of pollution control of this area. In order to understand the environmental background of the river basin under investigation and to estimate the degree of pollution of these rivers, RPI method was used for water quality, and the degree of potential hazards of heavy metals issued by EPB of NY State was used for sediment evaluation. The minimal and most stringent influential standards were used as the criteria for the evaluation. The USEPA sediment pollution risk assessment criteria were used as a reference to evaluate the magnitude of harm to human health and aquatic animals resulting from the sediment pollution. Fish, crustacea and aquatic insects were used for the biological evaluation. The multi variable statistical method was used to understand the relation between water quality and biological species; time and space dependence were also studied. According to the results of the above findings, we were able to identify different degrees of pollution for the whole river basin under investigation, and the distinctive pollutants and major biological species were identified for various sections of the river, and will serve as a guideline for future monitoring.
