dc.description.abstractWater samples from twenty one boreholes were col lected within University of Lagos and analyzed for physical properties. trace elements and cations using inductively coupled plasma optical emission spectrometry (ICP-OES). Physical analysis of the samples shows slight acidity and alkalinity with 78% of the samples exceeded recommended standards. They can be classified as fresh water based on TDS and EC. Chloride concentrations fall within water standards in mosts<1mples while AI, Na, Pb and Br exceeded·recommended standards in most samples. Gibbs plot, rel ationship between total c<1tions. Na + K . Ca .,. Mg and Cl showed that all the groundwater samples fall in the water-rock interaction field which suggests that the weathering of rocks and influence of sea water primarily controls the major chemistry of groundwater in the area. Sodium Absorpti on Ratio (SAR) for all the water samples was less than 10 and excel lent for irrigntion purpose. Only 33% of water samples were su itable for irrigation based on Soluble Sodium Percentage (SSP) and Magnesium A dsorption Ratio (MAR), whereas based on Kellys Ratios (KR) all the water samples were not good for irri.gation purpose having KR greater than I. Fifty percent of the water samples showed pollution index (PI) above I with highest contribution (37.8%) from lead (Pb). Mn, AI, N i, Fe and As contributed 29.3%, 19.13%, 8.66%, 4.25% and 0.8:2% respectivelyen_US
