摘要

In the current scenario, the application of remote sensing and GIS has been widely increased in the assessment of water quality. The main aim of this study is to investigate the nature of groundwater and its suitability for domestic and irrigation purpose in Vazhapadi Taluk, Salem district. 50 sample locations are selected in the study area and analysed for 12 basic water quality parameters. The physio-chemical properties are also compared with standard regulations. Based on the detailed investigation in terms of water quality index map is developed using GIS, it is predicted that some sample locations are in need of a primary degree of treatment for domestic usage. The studies also reveal that the majority of groundwater samples are suitable for irrigation purposes.

目前遙測及地理資訊系統（GIS）廣泛應用於水質評估。本研究主要目的在於研討地下水之特性及其是否適合作為國內Vazhapadi Taluk, Sale區之灌溉用水。研究地區內選出五十處樣本區，應用十二項基礎水質參數，同時將其化學物理性質與標準規範比較。採用地理資訊系統建立的水質指標地圖進行細密的研測，發現有些樣本區水源須經初步處理才可供國內使用。本研究也顯示多數地下水樣本是適合用於灌溉用途的。
