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.
