本計畫主要針對南區九縣市各類水體水質監測，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。河川水質計有31條河川主支流，109個監測站，於每月監測一次，95年1月至3月皆無明顯降雨屬枯水期，河水乾涸，河川污染物濃度偏高，造成嚴重污染比例偏高，其餘各月則因降雨豐沛，懸浮固體偏高，以致未(稍)受污染程度偏低，中度污染程度超過50%。海域水質計有8個沿海區域，42個監測站，於每季監測一次，各季沿岸測站受河口感潮影響，無機鹽類濃度較高，而大鵬灣沿海測站則因藻類作用，pH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5個休憩海域，15個監測站，於6月至9月每兩週監測一次，其中水質以杉原海水浴場較佳。水庫水質計有16個水庫，42個監測站，於每季監測一次，今年因降雨豐沛，透明度下降，各水庫大致呈現優養狀態。地下水水質計有9縣市，189個監測井，各縣市超過監測基準之比率介於10%～90%，其中超過地下水污染第二類監測基準主要項目為氨氮、鐵、錳。

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 environmental protection authorities. For river quality, there were 31 rivers, including main streams and sub-streams being monitored, 109 sampling sites were monitored monthly. Since there was a major water shortage for this year, particularly there were no rainfalls during the period from January to March, a part of rivers were nearly dried up, the test results for most pollutants were high, and thus the percentage of serious pollution would tend to look high. For ocean monitoring, there were 8 coastal areas being monitored, 42 sampling sites were monitored quarterly. Since the estuary areas were affected by the river during high tide, the concentrations of the inorganic salts were high in 1st quarter. 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 Shan-yuan Beach was the best. Sixteen water reservoirs, 42 sampling sites were monitored quarterly, water levels had all reached the alarm level due to water shortage in 2nd quarter, eutrophication phenomena were observed for most of the water reservoirs. There were 189 ground water sampling sites for the nine cities and counties being monitored quarterly, with the exception of Tai Dong County, ammonia nitrogen, iron, and manganese were the major items with results that reached the regulatory monitoring criteria. The failing rates are between 10 to 90% for different cities and counties.
