dc.description.abstractPreliminary hydro-chemical evaluation of River Niger Floodplain at Jebba, Nigeria was carried out using ICP/MS and AAS methods in order to assess its suitability for domestic and irrigation purposes. Relative abundance of cations concentration at the pond water, well water and stream water were: Na>Ca>K>Mg, Na>Ca>Mg>K and Ca>Na>K>Mg respectively while those of the anions were: Cl>HCO3>SO4>CO3>NO3, Cl>SO4>HCO3>CO3>NO3 and Cl>HCO3>SO4>NO3>CO3 respectively. The average values of Revelle Contamination Index for the water samples were greater than one, hence,the water is not good for human or domestic consumption. On the average, pond and stream waters range from soft tomoderately soft while the well water is extremely hard (influence of lithology). The pond, well and stream waters are slightly alkaline with average value of pH as 7.8, 7.5 and 7.8 respectively. Interestingly, the calculated Indices: Sodium Adsorption Ratio, MagnesiumAdsorption Ratio, Residual Sodium Carbonate, Residual Sodium Bicarbonate, Permeability Index, Kelly Ratio, Potential Salinity and Soluble Sodium Percentage, which could indicate the water quality for irrigation show that the water is safe for irrigation practices. However, caution must be made while using well W1 because it shows high value of Magnesium Absorption Ratio (54.62) and high value of Kelly Ratio (1.06) which makes it unfit for irrigation purposes.en_US
