Well water and Oniyere stream in the vicinity of a factory
manufacturing lead-batteries in Ibadan, Nigeria were
analysed for the following general physico-chemical
characteristics: pH, temperature, conductivity, total
alkalinity, total hardness, solids, chloride, nitrate,
ammonia, dissolved oxygen and chemical oxygen demand. The
samples were collected at six sampling locations along the
stream network (three locations at upstream and another four
at downstream) and from six wells in different households in
the neighbourhood of the factory. The levels of physico-chemical
characteristics investigated of the well water were
generally below the WHO guidelines for drinking water.
However, the well waters were poor in quality in terms of
the levels of pH, Fe, Cu, Ni, Pb and Cd recorded. The
factory wastewater impacts the stream with heavy metals.
Thus, the well water requires further purification to ensure
its suitability for human consumption.
