Groundwater is the largest freshwater source in arid and semi-arid regions across the world. Combinations of statistical methods and Geographic Information System (GIS) have been used to evaluate the spatial and temporal changes in hydrochemical parameters of groundwater in Nashik District, Maharashtra, India. Groundwater assessment is based on the hydrochemical parameters of the study area. Water samples were collected from 15 tehsils in Nashik. From each tehsil sixteen water samples were collected having ten well and six bore well samples. All 250 samples were analyzed for hydrochemical parameters such as pH, temperature, electrical conductivity, solids in water, alkalinity (CaCO3), carbonate and bicarbonate, chloride, sulphate (SO4), fluoride (F), total hardness (CaCO3), sodium observations were recorded. The aim of this paper is to study seasonal variations graphically and then Analysis of variance (ANOVA) has been performed to study seasonal variation among hydrochemical parameters. Through this ANOVA we have studied the difference between well and bore well samples statistically.
