Abstract

The only source of water supply in Lagos State University Ojo, Lagos State is sub surface water. Despite being under possible threats (natural and anthropogenic), the water is used for irrigation, domestic, recreation and drinking purposes, hence the need for quality verification so as to be sure of the safety of man. Therefore, this study sought the physicochemical quality assessment of groundwater in Lagos State University, main campus, employing standard procedures of American Public Health Association. Groundwater samples collected bimonthly from twenty five (25) wells were chemically investigated for pH, acidity, alkalinity, electrical conductivity, total dissolved solids, total hardness, anions and trace metals. Groundwater data generated from chemical laboratory were subjected to factor and cluster analyses. Six principal components (PCs) extracted 79.3 % of the total variance and five clusters of wells with distinct characteristics were also revealed. The order of exceedance of some quality parameters above WHO limits was NO32- > Mg > Fe > SO42- >TH, raising the question of safety on its potability. The sodium adsorption ratio (SAR), however showed that over 95% of the water samples analyzed are fit for irrigation purposes, thus portends safety for human health. The impact of agricultural activities among others are apparent on the quality of groundwater, hence the need for regular monitoring by relevant agency, in order to safeguard the safety of man and ensure sustainability of the environment.
