Abstract

Assessment of Groundwater Quality for Drinking and Construction uses in Odo-Oba Town, Southwestern Nigeria. 1Temilade Oladeji and 2Olufunmilayo Adewoye : helenetemi@gmail.com, aoadewoye55@lautech.edu.ng Abstract Groundwater is a crucial natural resource for human survival, serving as the primary source of freshwater worldwide. However, a lack of data on water quality can have detrimental effects on human health and resource management. This study aims investigates the chemical composition of groundwater in Odo-Oba, Oyo State, Nigeria, to assess its quality for drinking and construction. The objective is to evaluate the potential for possible contamination, to determine the water facies type and assess its suitabilityfor sustainable development using water quality indices, plotsand statistical analysis for potable water supply and construction purposes.Twenty groundwater samples were analyzed for physical and chemical parameters and were compared to international standards. Results showed slightly acidic water with moderate temperatures and elevated mineral content. Potassium was the most abundant cation, while chloride was the dominant anion. Most parameters were within acceptable limits, but some samples were unsuitable for drinking. Rock-water interactions significantly influence the water chemistry. While groundwater in Odo-Oba is unsuitable for drinking without treatment, it is suitable for construction. However, further microbiological analysis and proper waste management are crucial to protect groundwater resources. Testing concrete samples for pH changes is recommended to assess potential impacts on structural integrity. Keywords: Assessment, Groundwater, Quality, Construction, Drinking, Suitability
