Abstract

Abstract
The primary issue with the groundwater aquifer's concept of sustainability in the survey area is overexploitation. In addition to measuring the water depth in 65 groundwater wells for the purpose, standard analytical techniques were used to analyse 12 physiochemical properties. The investigation wells were built in order to provide groundwater management with preliminary data on water quality. Diagrammatical analyses, including hydrographs and Schoeller's semi-logarithmic diagrams, were used to manipulate water quality informations of the groundwater resources in the investigated region. The findings revealed that NaHCO₃ is the most prevalent type of water, followed by Na₂SO₄ and NaCl. The abnormally high content of the Fe element ranged between 2 and 10 mg/l, revealed rust-colored deposits on well screens, and sanitary fittings. As a result, the current flood irrigation system should be changed with more advanced drip and sprinkle agricultural technologies.
