Impact of Industrial Waste Discharge on Surface Water Quality of Choba River, Port Harcourt, Nigeria

Arimieari L. W., Wobo K. W.

Abstract


Assessment of surface water quality of the Choba section of the New Calabar River, Eastern Niger Delta was carried out. Three (3) surface water samples were collected for the study. The physicochemical parameters studied were: TSS, TDS, Zn, Fe, Cd, Cr, and Cu for surface water. The World Health Organization's (WHO) guidelines were applied while assessing the heavy metal Pollution Index (PI) in surface water.  The other samples that were evaluated showed high levels of pollution; the other samples had low levels of contamination, while Cu, Cr, and Mn had moderate to significant levels. For surface water, Pb and Zn had high Pollution Index values, with Pb having PI values ranging from 1.62319-5.97087, with considerable contribution of pollutants from anthropogenic activities into the river. Regular monitoring of the Choba segment of the River is of paramount importance. To prevent more pollution, the government regulatory body in charge of environmental protection needs to give this section of the river enough attention.
