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35條河川主支流，131個監測站，於每月監測一次。今年度上半年北部地區適逢旱象，部份河川污染物濃度有偏高之情形。海域水質計有6個沿海區域，36個監測站，於每季監測一次。曾於第三季在花蓮沿海有DO有不符合海域環境品質標準之現象。近岸休憩海域水質計有2個休憩海域，6個監測站，於6～9月每兩週監測一次，除福隆海水浴場因河水改道匯入而受影響外，水質均屬良好。水庫水質計有34個水庫，47個監測站，於每季監測一次，今年度由於適逢缺水，水庫水位降踰警戒線，而有水質狀況較差之現象。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及金屬錳。

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-one sampling spots to monitoring the stream water quality including thirty-five streams and branches once every month. The result of the project shows a major factor influenced the water quality was the weather. A critical drought took place in northern part of Taiwan this year produced far more less rain than the same time in past years. Therefore, concentration of many pollutants were found higher than usual. On the other hand, the seasonal results of thirty-six coastal monitoring spots for the six marine water regions appear that the DO are 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. Generally, the water quality of these two coastal regions seems to be good except for the the influence of the stream input caused by chawging path on Fu-long Coast. Regarding on the reservoir water quality, thirty-four monitoring spots for the thirty-four dams has sampled worse quality of water in this year due to the lack of rain fall and the drop of water to the warning level. 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.
