Water is one of the most important resources which is very crucial for our daily life. Surface water and ground water are the two types of sources from which we obtain this essential resource. Erratic and unequal availability of surface water leads to exploration of ground water for irrigation, industrial and domestic purposes. Therefore, the quality of ground water is equally important as its quantity. In the present study, geo-spatial technology has been applied for maping the spatial distribution of ground water quality in in Champhai district of Mizoram, India. Ground water samples were collected from 118 point sources randomly distributed within the study area. The concentration of major water quality parameters such namely pH, Total Dissolved Solids, Alkalinity, Total hardness, Iron, Chloride, Nitrate and Fluoride have been assessed for all the sampling locations. The spatial variation maps of these ground water quality parameters were generated and utilize as thematic layers. Different classes within each thematic layer were assigned weightages in numerical rating from 1 to 3 as attribute values in GIS environment. Summation of the attributes values of the thematic layers were utilizes to generate the final ground water quality map. This final map shows the different classes of ground water quality within the district which can be utilize to give a guideline for the suitability of ground water uses.
