Quality evaluation of commercially sold table water samples in Michael Okpara University of Agriculture, Umudike, Nigeria and surrounding environments

In Michael Okpara University of Agriculture, Umudike, Nigeria (MOUAU) and surrounding environments, table water of different brands is commercially hawked by vendors. To the best of our knowledge, there is no scientific documentation on the quality of these water samples. Hence this study which evaluated the quality of different brands of water samples commercially sold in MOUAU and surrounding environments. The physicochemical properties (pH, total dissolved solids (TDS), biochemical oxygen demand (BOD), total hardness, dissolved oxygen, Cl, NO3, ammonium nitrogen (NH3N), turbidity, total suspended solids (TSS), Ca, Mg, Na and K) of the water samples as indices of their quality were carried out using standard techniques. Results obtained from this study indicated that most of the chemical constituents of these table water samples commercially sold in Umudike environment conformed to the standards given by the Nigerian Industrial Standard (NIS), World Health Organization (WHO) and American Public Health Association (APHA), respectively, while values obtained for ammonium nitrogen in these water samples calls for serious checks on methods of their production and delivery to the end users.
