Abstract:
One of the crucial natural resources that satisfies the needs for drinking and irrigation is groundwater. The rising requirement for water in irrigation is achived by groundwater resources. Hence, a geo-spatial study was directed for groundwater testing for water quality valuation to regulate the appropriateness of water for irrigation purpose. With the help of GIS tools, the current study was started with the goal of estimating groundwater quality and mapping its spatial distribution for the north Sindhudurg area. In the present study, ground water samples from different location of four tehsils of north Sindhudurg district for five-year period (2016-2020) has been collected from Groundwater Survey and Development Agency (GSDA) Sindhudurg. The Weighted Arithmetic Water Quality Index approach was examined for five years based on ten physicochemical parameters (Total Dissolved Solids, Electrical Conductivity, pH, Calcium, Total Hardness, Sulphate, Sodium, Potassium, Chloride, and Total Alkalinity). The geographic allocation of water quality index maps was created using the IDW interpolation method. Q-GIS software is used to create a map of the water quality index. The analysis of groundwater quality was found that resulted values of water quality index for the all studied five years are comes under ‘Good to Excellent’ class. This shows that the groundwater in study area is appropriate for irrigational use. Therefore, application of this groundwater for irrigation purpose is not hazardous for soil fertility.
