Keywords: Cement plant, Ewekoro, groundwater quality parameters, piper analysis, Sustainable Development Goals.
Cement manufacturing and industrialisation contribute significantly to the economic growth of nations, especially in Nigeria. However, industrial activities have been reported to be a severe source of pollution; hence, proper environmental monitoring must be ensured to control the adverse impacts of cement manufacturing activities for a sustainable ecosystem. This study investigated the effects of the Lafarge Cement Plant on the physicochemical properties and trace metal load in groundwater in the surrounding area. Twenty (20) underground water samples were obtained from different hand dug wells over twenty-four months around the cement factory, and investigated for quality parameters including pH, total dissolved solids (TDS), electrical conductivity (EC), total alkalinity, total acidity, total hardness, anions: sulphate (SO42-), chloride (Cl-), phosphate (PO43-), and nitrate (NO3-) as well as cations: nickel, cadmium, lead, copper, iron, zinc, calcium, sodium and potassium. Various statistical analyses were also carried out. All quality parameters analysed in the dry season were within the World Health Organisation (WHO) allowable limits, while Fe, Cd, and Pb have concentrations above the WHO acceptable limits. Piper analysis reveal hydrochemical facies of Mg2+ - SO42-, Na+ - Cl- and Na+ - HCO3-. These results indicate possible groundwater pollution, which may pose a health risk. Hence, there is a need for regular monitoring of groundwater pollution so as to ensure health safety and environmental sustainability, in line with goals 3, 6 and 11 in the Sustainable Development Goals.
