Assessment of physicochemical parameters and trace metals were carried out in groundwater of Ibese town and environs, Southwest Nigeria. The mean value of pH, electrical conductivity (EC), total dissolved solid (TDS) and alkalinity (HCO32-) are 5.90 ± 0.32, 1328.00 ± 676.26 µScm-1, 664.00 ± 353.58 mgL-1 and 94.00 ± 18.55 mgL-1. The chloride concentration was found to be higher than World Health Organization (WHO) recommended limit of 250 mgL-1 in drinking water in majority of the samples. The suitability of the water for irrigation was established using sodium adsorption ratio (SAR) which ranges from 2.61 to 11.56. Concentration of heavy metals [Lead (Pb), Manganese (Mn), Nickel (Ni) and cadmium (Cd)] was determined using atomic absorption spectrophotometer and most of them are below detection limit of the instrument. It was concluded that the alkalinity was as a result of water-rock reaction, and treatment to remove high chloride concentration is required before consumption. The establishment of Dangote cement factory in the area should facilitate the provision of potable water for the inhabitants by the company as part of community service.


Key words: Ibese, groundwater, cement, heavy metals, sodium adsorption ratio.
