The goal of this project is to monitor the water qualities of nine cities and counties located in the southern area of Taiwan, and to proceed with the analysis of degree of pollution to various water bodies through understanding the trend of variation of various water qualities with time, the result of this investigation can provide grounds for policy making to environment protection authorities.
For river quality, there were 34 rivers, including main streams and sub streams being monitored, 101 sampling sites were monitored monthly. Since there was a major water shortage for this year, particularly there were no rain falls during the period from January to May, most rivers were nearly dried up, the test results for most pollutants were high, thus percentage of serious pollution would tend to look high.
For ocean monitoring, there were 8 coastal area being monitored, 42 sampling sites were monitored quarterly. Sea water qualities near the river junction area were obviously influenced by the river during high tide, some test results of dissolved oxygen exceeding the regulation control were observed. There were also 5 beaches being monitored, 15 sampling sites were monitored biweekly during period of June to September. Among the 5 beaches, the water quality of Golden Coast Beach was the worst, and Chi-ching Beach was the best.
16 water damps, 42 sampling sites were monitored quarterly, water levels were all reaching the alarm level due to water shortage, oxygen enriched phenomena were observed for most of them.
There were 124 ground water sampling sites for the nine cities and counties being monitored quarterly, ammonia nitrogen and manganese were the two major items with results that didn’t meet the government regulation control, the failing rate is between 50 to 100% for different cities and counties.
