Abstract

This research is to investigate the quality of ground water in boreholes and hand-dug wells during the dry season in six locations in Port Harcourt metropolis of Rivers State. The locations are Rumuola, D-line and Trans-Amadi, which use borehole while Elechi Beach, Gbundu and Ozubuko still use hand-dug wells.
The parameters analysed were iron, chloride, hardness, and pH. Others were total dissolved solids (TDS), ammonia (free and saline), and E-coli. Results indicated that for iron, all except Ozubuko with a value of 0.32mg/l satisfied WHO’s standard. It is not sufficient, however, to reject water containing higher iron content unless a more suitable supply is available. For parameters such as chloride and hardness, the samples from all the locations are within WHO’s limit. This is also true for TDS, while for pH, the water samples from all the locations were acidic, falling short of the standard (6.5 – 8.5) specified by WHO although samples from Rumuola with the highest value of 6.66 fall within the WHO range and hence acceptable. Ammonia levels in the water samples from all the locations were within the recommended value by WHO, with the highest value (5.01) coming from Trans-Amadi, which indicates the highest level of biological reductions in this water. Finally and of greater significance too, is the fact that no E-coli was found in all the samples except that from Gbundu waterside with a level of 3 x 103 as against zero recommended by WHO. This therefore makes the hand-dug well water from Gbundu warterside unsuitable for human consumption.
