摘要	The main goal of this project is to monitor the water quality of nine cities and counties in the southern area of Taiwan, and to analyze the degree of pollution in various bodies of water so that trends in water quality can be observed. The result of this investigation can provide grounds for policy making to environmental protection authorities. 　　For river quality, 109 sampling sites covering 31 rivers (including main streams and tributaries) were monitored monthly. The results of 2007 shows that the water quality in the area of Zeng-Wen river were the best, the area of Jiang-Jun river and Er-Ren river were found in relatively high extent of pollution. Since there was a major water shortage this year, specifically, a lack of rainfall from January to May, parts of some rivers were nearly dried up, so test results for most pollutants were high, and thus the percentage of serious pollution would tend to look high. Due to a lot of rainfall in June and August through October, the suspended solids in the rivers tend to be high thus the percentage of unpolluted rivers is low and over 50% of the results indicated the rivers were intermediately polluted. As a whole, the highest percentage of the water quality is 38.1%, it belongs to intermediately polluted rivers ;the next is 29.0%, it belongs to unpolluted rivers, overall water quality in this year is nondifference between the recent years. 　　For ocean monitoring, 42 sampling sites covering eight coastal areas were monitored quarterly. Since the estuary areas were affected by the river during high tide, the concentrations of the inorganic salts were high. The results of 2007 shows that most monitoring data could meet quality criteria of each category, except the results of ammonia nitrogen monitored at estuary areas of Dong-Gang river and Da-Peng Bay. Because of typhoon coming in 3rd quarter, there are some index including temperature, salinity and some metal ions different with the past results, but there is no significant difference disappeared in 4th quarter. 　　Fifteen sampling sites covering five beaches were monitored biweekly from June to September.

Due to a lot of rainfall at 26th August and 1st October, the results were showed common level.
