Evaluation of the Quality of Groundwater for Irrigation Purposes in Karur District, Tamilnadu, South India

Abstract

This work aimed to evaluate several physicochemical characteristics in irrigation water over acceptable criteria. The research for this paper was conducted during the construction of the Karur District in the state of Tamil Nadu in South India. In order to conduct the investigation of the water's quality, 201 open-air wells provided the source for the water samples. The field survey design was utilized and complemented by laboratory testing to analyze the levels of physicochemical parameters in both seasons (pre-monsoon and post-monsoon seasons) for groundwater and water bodies. Sodium Adsorption Ratio (SAR), Soluble Sodium Percentage (SSP), Magnesium Adsorption Ratio (MAR), Kelly Index (KI), pH, Electric Conductivity (EC), and Total Dissolved Solids (TDS) were the physical and chemical parameters that were analyzed. The average electrical conductivity values were relatively high, despite our studied samples being within the allowable range for irrigation water quality.
