, electrical conductivity (μS/cm), turbidity, alkalinity (Alk), total hardness (TH) and concentrations of sulphate (SO<sub>4</sub><sup>2-</sup>), nitrate (NO<sub>3</sub><sup>-</sup>), phosphate (PO<sub>4</sub><sup>3-</sup>), chloride (Cl<sup>-</sup>), total suspended solids (TSS), total dissolved solids (TDS), total solids (TS), heavy metals (Pb, Cr, Cd, Mn, Ni, Fe). Results showed that TSS, TDS, TS, SO<sub>4</sub><sup>2-</sup>, Turbidity, Fe, Cr, Cd, Mn, Ni and Pb concentrations were above the maximum permissible limit of National Administration for Food, Drugs and Control (NAFDAC), Standard Organization of Nigeria (SON), Federal Environmental Protection Agency (FEPA) and World Health Organization (WHO, 2006) for drinking water during some months of the study period. However, the water temperature, pH, conductivity, NO<sub>3</sub><sup>-</sup>, PO<sub>4</sub><sup>3-</sup>, Cl<sup>-</sup> and Alk levels were within the permissible limits of all the standards. Since most of the parameters measured were above the maximum permissible limits of the national and international standards, it can be concluded that the water is unfit for domestic uses, drinking and aqua cultural purposes. Consistent water quality monitoring to the status of the study area is suggested for human and environmental sustainability.&picture=http://www.aascit.org/aascit/decorators/img/journal/904.jpg)

The negative impact of industrial discharges into freshwater on wellbeing of man and environment prompted the assessment of the quality of water around Lafarge Cement WAPCO, Ewekoro, Ogun State. The water samples were analysed using standard methods for its pH, temperature (°C), electrical conductivity (μS/cm), turbidity, alkalinity (Alk), total hardness (TH) and concentrations of sulphate (SO42-), nitrate (NO3-), phosphate (PO43-), chloride (Cl-), total suspended solids (TSS), total dissolved solids (TDS), total solids (TS), heavy metals (Pb, Cr, Cd, Mn, Ni, Fe). Results showed that TSS, TDS, TS, SO42-, Turbidity, Fe, Cr, Cd, Mn, Ni and Pb concentrations were above the maximum permissible limit of National Administration for Food, Drugs and Control (NAFDAC), Standard Organization of Nigeria (SON), Federal Environmental Protection Agency (FEPA) and World Health Organization (WHO, 2006) for drinking water during some months of the study period. However, the water temperature, pH, conductivity, NO3-, PO43-, Cl- and Alk levels were within the permissible limits of all the standards. Since most of the parameters measured were above the maximum permissible limits of the national and international standards, it can be concluded that the water is unfit for domestic uses, drinking and aqua cultural purposes. Consistent water quality monitoring to the status of the study area is suggested for human and environmental sustainability.
