Samples were analyzed for water quality parameters like pH, EC, TDS, TH, Cl - , SO 4 2- , NO 3 - , F - etc., using standard techniques and compared with the standard values so as to reveal extent of pollution levels in some villages. Correlation analysis was carried out between various parameters by using SPSS. Some parameters like EC-TDS, TH-TDS, EC-Cl - , Na + - TDS etc. exhibited highly positive correlation whereas pH showed negative correlation with most of the parameters. Cluster analysis was also done between different parameters for different villages of Tehsil. Geochemical assay indicates immediate water quality improvement by sustainable management.

Over last few decades, competitive economic development and rapid growth in population & urbanization has brought in significant changes in land use. It resulted in excessive demand of water for agriculture and domestic activities. It necessitated a study of parameters of geochemical importance. In this regard, statistical correlation analysis has been found to be useful tool for correlating different parameters. Correlation analyses measures the closeness of relationship between chosen independent and dependent variables. Thus it attempts to establish nature of relationship between various parameters [1-2] and thus provides a mechanism for prediction or forecasting. Experimental Materials and Methods This paper aims to make an assay of water quality index so as to predict ways and means for ascertaining the suitability of ground water for domestic use in Sanganer Tehsil, Jaipur. Study Area: Sanganer tehsil is attached with main city of Jaipur. Its geographical positioning lies between 26°49’N to 26°51’ N latitude and 75°46’E to 75°51’ E longitude and has land area of 635.5 sq. km. The climate of the area is hot semiarid with extremes of temperature (15-45°C) and rainfall 650 mm. Water samples of Sanganer area were collected with a view to understand and assess the quality of potable water as now it almost has the status of a suburb of Jaipur. Water sampling, preservation and data analyses: A total 40 samples were collected from different wells, tube-wells or hand-pumps from 40 villages of Sanganer Tehsil during post-monsoon period [From October 05 to 15, 2014].
