Abstract
The physicochemical properties of groundwater were studied by collecting and analysing samples from several sites in and around the Salem region. Thirty samples of groundwater were taken at random from both open wells and borewells. The water quality metrics pH, EC, TDS, Cl-, Bi, SO4 2-, Si, Fe, Al, Ca++, Mg++, and Na+ were used to evaluate the groundwater in the Salem area. Different locations in the Salem area provided information on the quality of the groundwater in the month of October, 2021. The WHO and BIS criteria were used to evaluate the groundwater's viability as a source of drinking water and irrigation. The Sodium Adsorption Ratio (SAR), Water Quality Index (WQI), Piper diagram, and Wilcox's categorization were used in the assessment of the water quality. Piper's trilinear diagram was used to determine the impact of anions and cations. Almost all the study regions have questionable groundwater quality during the winter months, making it unsuitable for use in irrigation.
