In the study, health risk assessment on heavy metals ingestion was presented through the groundwater drinking pathway for residents in an oil and gas producing area of Rivers State, Nigeria. The level of the ground water pollution was examined, the quality of the borehole and the well water was assessed and the quality of the ground water pathway for the resident in the oil and gas producing area was determined and compared with the national and international standards for the drinking water. This study adopted both the field and laboratory experimental analysis of physical and chemical parameters. Water samples were analyzed for Physico-chemical parameters following acceptable methods to determine the compliance, and the results were analyzed according to drinking water guidelines. Interestingly, the results show that the ground water contained high amounts of turbidity (21.5 NTU, 23.00 NTU and 19.0 NTU in the borehole water and well water), iron (5.3 mg/L in the ground water and 6.98 mg/L in the borehole water) and pHs of all water samples were acidic in the study area. These results show that ground waters including the borehole and the well waters of the study area had acquired reasonable levels of pollution. Whereas, other values were found to be lower or above and corHow to cite this paper: Olalekan, R.M.,

Environmental problems of the textiles industries are mainly cause by the discharge of wastewater coming from the dyeing and finishing processes containing the heavy metals. This study assessed the heavy metals concentrations in the surface water body of neighboring Funtua and Zaria textile industry and effluent water collected from Funtua textile industry using atomic absorption spectrometer (AAS). The concentrations of heavy metals like Lead (Pb), Cadmium (Cd), Iron (Fe), Zinc (Zn) and Coppernicium (Cn) were assessed and the concentrations of each of the metals varies in the samples collected and analyzed with the following values: Funtua water samples Fe 0.0025 mg/l lower part and 1.63 mg/l upper part, Zn 0.51 mg/l lower part and 1.02 mg/l upper part, Pb 0.007 mg/l lower part and 0.61 mg/l upper part, Cd 0.01 mg/l lower part and 0.016 upper part, Cn was not detected (ND), for effluent Fe 3.61 mg/l and 2.61 mg/l, Pb 2.66 mg/l and 2.69 mg, Cd 0.99 mg/l and 1.06 mg/l, Zn 2.26 mg/l and 2.99 mg/l, Cn ND also and for Zaria water samples Fe 0.96 mg/l lower part and 2.15 mg/l upper part, Zn 1.07 mg/l lower part and 1,74 mg/l upper part, Pb 0.36 mg/l lower part and 1.02 mg/l upper part, Cd 0.41 mg/l lower part and 0.66 mg/l upper part and Cn ND also. Fe and Pb showed concentrations higher than limits set by the NSDWQ and WHO while Zn and Cd showed concentrations below limits set by NSDWQ and WHO. The river neighboring Zaria textile happened to be more polluted than the one neighboring Funtua textile industry. It was concluded that the effluent samples of textile industries discharge causes pollution to the water bodies and serious problem for living being and ecological environment. Therefore, the effluent water to be discharged by these industries must be adequately treated before discharge.
