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，在河川水質方面，東北部宜蘭、花蓮地區河川普遍污染不大，水質較好；淡水河系河川下游則在有機物及氨氮污染濃度有較高之情形，而於上游水質較佳；西北部桃園、新竹地區河川，則以新竹頭前溪流域水質狀況最佳，而以桃園南崁溪、老街溪、茄苳溪、新竹茄苳溪及客雅溪水質污染較為嚴重，同時桃園老街溪在金屬銅、鋅有長期測值偏高之現象；另於3月以及6～9月分別受到冷氣團鋒面經過降雨以及夏季颱風過境與外圍環流影響，桃園、新竹及東部山區則有水質較濁之情形。海域水質計有8個沿海區域，43個監測站，於每季監測一次，本年度在各縣市沿海之各項監測結果除基隆與台北沿海曾有溶氧未符合水質標準外，其餘則皆符合海洋環境品質標準。近岸休憩海域水質計有2個休憩海域，6個監測站，自6月6日起至9月底前，每兩週監測一次。本年度6～9月之監測結果，北部休憩海域水質除第二次福隆海水浴場受到河水匯流影響，有不符甲類海域水體水質標準外，其餘多屬優良。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，新山水庫皆為普養，西勢及翡翠水庫介於貧養至普養之間，寶山水庫、石門水庫、儲水沃下霸、儲水沃上霸、橋仔、紫沃、福正及菜浦沃則屬於普養至優養之間，其餘水庫則皆屬於優養，且多集中於外島湖庫。地下水水質計有7縣市，120口監測井，水質方面則與往年類似，達第二類監測基準之項目主要集中於氨氮、金屬錳及鐵等三監測項目，與各環保單位歷年對台北盆地、桃園中壢台地及新竹苗栗沿海地下水之監測結果相符合。

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 134 sampling spots to monitoring the stream water quality including 36 streams and branches once every month. The result of the project shows a critical distinguishes between upstream & downstream was shown in Danshuei -river. The water quality was per-bad in Taoyuan & Hsinchu. Furthermore, because of the rainfall on March and during summer, the river water was sometimes more turbid. On the other hand, the seasonal results of 43 coastal monitoring spots for the 8 marine water regions appear that only DO was ever found exceeding their relative marine water quality standards in Keelung and Taipei. In addition, two recreational coasts has been intensively monitoring once every two weeks during summer period between June and September. Generally, besides the Fulong beach was found exceeding the water quality standard on June 20, the water quality of these two coastal regions seems to be good. Regarding on the reservoir water quality, the resulf of 47 monitoring spots for the dams shows that reservoirs in Keelung and Feitsui Reservoir was between oligotrophic and mesotrophic, the other reserviors in north Taiwan were between mesotrophic and eutrophic, and the reservoirs in Kin Men and Matsu were analyses to be on a situation of eutrophication. Finally, for those 120 ground water monitoring wells within 7 municipal regions in northern Taiwan, NH3-N, Fe and Mn reach the Ground Water Monitoring Standard in second category.
