Quality of Underground Well Water in Obiagu Area, Enugu State, Nigeria |Biomedgrid

This study was aimed at assessing the quality of underground well water in Enugu metropolis. Samples were collected from closed wells at a depth of 120-150 m high from the ground level into clean sterile plastic containers from four (4) different locations: Old artisan, Oriefete, Obiagu and Ani Street. These samples were taken to laboratory for physiochemical parameters (pH, conductivity, total dissolved solids, total suspended solid, nitrate, acidity and alkalinity), heavy metals (arsenic, mercury and chromium) status and bacteriological quality. Results showed a huge nonconformity from safe standard limit established by the World Health Organization (WHO) as some of the values were much higher. The presence of some pathogenic bacteria (Escherichia coli, Clostridium perfringens, Streptococcus faecalis, Enterobacter aerogenes) is also a major indicator of bacterial contamination. This implies that the underground water well of the selected areas is not safe and it needs some great deal of treatment before consumption.
