Groundwater Quality Assessment for Irrigation Suitability Purpose in the Khelna River Basin of Aurangabad District, Maharashtra, India

Abstract

The present study is based on irrigation suitability for groundwater samples in the Khelna river basin, Chhatrapati Sambhajinagar (Aurangabad), Maharashtra, India. A total 50 groundwater sample were collected, out of 50 groundwater sample 16 groundwater samples were collected from bore well and 34 groundwater samples collected from dug wells in high quality of one litter polyethylene bottles from different locations within the study area. The irrigation water quality parameters like sodium adsorption ratio (SAR), Percent sodium (%Na), Residual sodium carbonate (RSC), Residual Sodium Bicarbonate (RSBC), Kelly’s ratio (KR), Magnesium adsorption ratio (MAR), and Permeability index (PI) were calculated with the help of physico chemo analysis of groundwater sample using standard formulae was given in Table 1. The irrigation water quality parameters values are measured like SAR (0.63 to 2.89), %Na (1.04 to 6.96), RSC (-6.14 to 0.59), RSBC (-1.54 to 3.91), KR (0.19 to 0.76), MAR (25.78 to 78.78) and PI (36.46 to 72.78). All the irrigation parameters are reveled the value in suitable category for irrigation except MAR (Magnesium hazard). Magnesium hazard water samples that exceed acceptable limits have been recognized in the study area because of different geological and human activities. This study is beneficial for farmers and policymakers in managing and planning groundwater resources.
