本計畫主要針對新店溪、淡水河本流、急水溪、曾文溪、鹽水溪及東港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程度評估(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，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，訂定各河段之指標污染物及指標生物，作為後續監測之參考依據。

The main purpose of this project is to investigate the basic background for the water and sediment of Dong Gang River, Ji Shuei River, Zeng Wen River, Shin Dian River, Tan Shuei River and Yan Shuei River, and to analyze the concentration of pollutant 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 possible potential pollution and most possible source of pollution, these findings can serve as a guideline for the management of pollution control of this area. In order to understand the environmental background of the river basin under investigation, degree of pollution of these rivers were being estimated, RPI method was used for the water quality, and the degree of potential hazard of heavy metal 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. Fishes, crustacea and aquatic insects was used for the biological evaluation. The multi variable statistical method was used to understand the relation between water quality and biological species, also time and space dependence were studied. According to the results of the above findings, we were able to identify different degree of pollution for the whole river basin under investigation, and the prior pollutant and major bio species were identified for various section of the river, and will serve as the guideline for future monitoring.
