Industrial and Residential Ground Water Physico-Chemical Properties Assessment in Lagos Metropolis
Abstract. This study investigated ground water quality collected from two industrial and residential locations each of Lagos metropolis. Prescribed standard procedures of American Public Health Association (APHA) were used to measure physico-chemical parameters of each of the ground water samples which include pH, EC, DO, TDS, BOD, COD, anions (Cl−, NO3−, SO4−, PO4−) and heavy metals (Cu, Zn, Pb, Mn, Fe, Co, Cd and Cr). From laboratory analysis, measured physico-chemical parameters were within the permissible ranges specified by WHO and NSDWQ except pH, TDS, EC, Pb, Mn and Fe for ground water samples from industrial locations and pH, Pb, Mn and Fe for residential locations. Higher concentrations of TDS and EC reported for ground water samples from industrial locations were attributed to heavy discharge of effluents from industrial treatment plants as well as dissolution of ionic heavy metals from industrial activities of heavy machines. Statistical Pearson’s correlation revealed physico-chemical parameters to be moderately and strongly correlated with one another at either p ˂ 0.05 or ˂ 0.01. In conclusion, ground water samples from residential locations are more suitable for drinking than those from industrial locations.

Contamination of ground water as a result of industrial effluents has been on rampage. Thus, this research work investigated physico-chemical properties of ground water samples collected from both industrial and residential locations via prescribed standard procedures of American Public Health Association. Results revealed residential ground water samples to be more suitable for drinking than those from industrial locations due to contaminations from industrial effluents.
