abstract = {Problem statement: The impact of anthropogenic activities on Otamiri and Oramiriukwa
Rivers as a result of the increasing rate of urbanization in Owerri, Nigeria is of a great concern due to
the fact that water from these rivers is the source of water distributed for public use. These rivers are of
particular importance in the study of surface water pollution because effluents from industries,
municipal waste, agricultural and urban run-off are discharged into it thereby deteriorating the quality.
Approach: This study used the application of Water Quality Index (WQI) in evaluating the quality of
Otamiri and Oramiriukwa Rivers for public usage. This was done by subjecting the 180 samples
collected to comprehensive physicochemical and bacteriological analysis using APHA standard
methods of analysis. Results: The overall WQI for the samples was 174.49. The high concentration of
conductivity, color, total solids, turbidity, total coliform, iron, manganese, COD, BOD and nitrate were
responsible for the high value of WQI which may be attributed to the anthropogenic interference along
the river bank. The results of the analysis when compared with the Nigerian Standard for Drinking
Water Quality (NSDWQ) permissible limit showed that the rivers were polluted and that the water is
not safe for domestic use and would need treatment. Conclusion: The use of WQI in elucidating
surface water quality evaluation and management has been demonstrated by this study. WQI is also
valuable tool in categorizing the pollution sources of surface waters.},
