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. On the other hand, the seasonal results of 43 coastal monitoring spots for the 8 marine water regions appear that none was ever found exceeding their relative marine water quality standards in all marine regions. 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 19 and September 25, 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 show 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.
