Interpretation of ground water quality parameter for selected area of Jaipur using regression and correlation analysis

Groundwater is an important source of water supply due to its relatively low susceptibility to pollution in comparison to surface water. Polluted ground water adversely affects the human health as well as environment. This paper assessed ground water quality index and regression analysis of selected area of Jaipur. Ground water samples collected from 12 different locations of South west area of Jaipur in dry season (April 2010). Results indicates that significant correlation and regression occur between TDS & EC (.996), TDS & Cl (.987) ,TDS & Na (.945), EC& Na (.948) , Cl & Na (.936). i.e. Total dissolved solids (TDS) is an important physicochemical parameter of drinking water quality .The water quality index of the area in dry season was 123.76 indicate poor quality of water for drinking purpose.
