本計畫主要針對北區十縣市各類水體進行水質監測，掌握各水體水質時間變化趨勢，並進行各水體污染評估分析，以提供環保單位污染防治決策之參考。 本計畫河川水質計有36條河川主支流，134個監測站，於每月監測一次。監測結果顯示，除8、9月間各地河川由於受颱風降雨影響，有水質較濁之情況，另在基隆河上游則因有員山子分洪工程及護岸及河道整治工程進行，以及懸浮固體有明顯提升之情形外，其餘河川大多與以往類似，淡水河流域在上、下游有水質狀況差異明顯之情形，桃園、新竹地區河川則因多為工業廢水、民生污水之承受水體，水質狀況普遍不佳，新竹頭前溪流域及東部宜蘭、花蓮地區河川則水質狀況普遍較好。海域水質計有6個沿海區域，36個監測站，於每季監測一次。本次在各縣市沿海之各項監測結果均符合海域環境品質標準。近岸休憩海域水質計有2個休憩海域，6個監測站，自5月31日起至10月初，每兩週監測一次。本年度之監測結果，北部休憩海域水質除福隆海水浴場9月間之試分級屬於不符甲類標準外，其餘之水質狀況均屬優良。水庫水質計有34個水庫，47個監測站，於每季監測一次，本年度監測結果顯示，尤於受到豐水期降雨影響，本島水庫皆有水位上升之情況；而在水庫營養狀態方面，除翡翠水庫為為貧養，新山及西勢水庫為普養外，其餘水庫則皆屬於優養狀態。地下水水質計有7縣市，127個監測井，主要達第二類地下水監測基準之項目為氨氮、金屬錳及鐵。

The project is to monitoring water quality of various water bodies, so that the changes of water quality to the time and pollution assessment for those water bodies could be provided to the relevant environmental agencies for making a sound pollution control decision. There are a hundred and thirty-four sampling spots to monitoring the stream water quality including thirty-six streams and branches once every month. The result of the project shows a increasing of suspend solid concertinos caused by the rainfall of typhoon between August and September, and it also shows a major factor influenced the Keelung-river water quality was the engineering. Beside this, the water qualities of the other streams were similar as usual. A critical distinguishes between upstream & downstream was shown in Danshuei -river. The water quality was per-bad in Taoyuan & Hsinchu. On the other hand, the seasonal results of thirty-six coastal monitoring spots for the six marine water regions appear that none was ever found exceeding their relative marine water quality standards. In addition, two recreational coasts has been intensively monitoring once every two weeks during summer period between June and September. Beside the Fulong beach was found exceeding the water quality standard on September, the water quality of these two coastal regions seems to be good. Regarding on the reservoir water quality, forty-seven monitoring spots for the thirty-four dams has sampled on a higher water level than the front 2 years. Among the 34 dams, Feitsui Reservoir was oligotrophic, reserviors in Keelung were mesotrophic, and the others were analyses to be on a situation of eutrophication. Finally, for those a hundred and twenty-seven ground water monitoring wells within seven municipal regions in northern Taiwan, NH3-N and Mn reach the Ground Water Monitoring Standard in second category.
