Determination Of Concentration Of Some Pollution Cations, Antions And Metals In The Groundwater Of Area Tiji In Libya

Abstract

Water is the world's most vital natural resource, essential for sustaining all forms of life and promoting economic and societal development. The aims of this research are to determine whether the concentrations of some cations, anions, and metals of the Tiji groundwater are above safe limits, which would indicate they may be potential polluters, to explore the presence of the chemical elements and their likely environmental and health impacts, to raise awareness among the community of the risks of consuming untreated groundwater and encourage ongoing water quality monitoring, to explore cost-effective and effective chemical treatment technologies ion exchange and polymer-based chelating processes of removing polluting substances from groundwater, to assist future planning of sustainable water management strategies for arid regions like Tiji. Experimental study was conducted on groundwater samples collected from three representative wells in the Tiji region, Libya (wells at approximately 30 m and 120 m depths as indicated in the study site selection. The results indicate that the groundwater in the Tiji region is mineral-hard and chemically hard with high levels for sulfate, chloride, hardness, and TDS, rendering it unfit to be consumed directly by humans without treatment. Exper-imental and analytical data strongly confirm Hypothesis 1 (H1). The high initial sulfate and chloride levels in the groundwater warrant the need for selective removal, and the ion exchange process. Hypothesis 2 (H2) holds well, i.e., AnaLig ME-0₂ chelating resin have very good adsorption efficiency of Lead and mercury. Installation of a complete water treatment system with anion exchange resins is recommended for effective reduction of sulfate and chloride levels.
