Preliminary Assessment of Physical Quality and Escherichia coli of Pipe Water in Nyankpala Campus of the University for Development Studies, Ghana
Keywords:drinking water, E. coli, faeces contamination, physical quality, pipe borne water
The main source of water for students and residents in University for Development Studies, Nyankpala campus and its environs is pipe borne water. This study was to assess the physical quality and E. coli count of drinking water from pipes. Water samples were taken from Dalun treatment plant, Dalun community, Bagabaga distribution point, Bagabaga community and Nyankpala campus. Membrane filtration technique was used to enumerate E. coli in the water samples. All the physical parameters were within the World Health Organisation (WHO) limits for potability except turbidity. The turbidity values recorded ranged from 1.98 to 28.90 NTU with a mean value of 9.18 ± 7.04 NTU compared to the WHO limit of 5 NTU. The study showed two of the samples that recorded the presence of E. coli and can be attributed to leakages in the pipelines. E. coli presence in the water samples indicates the presence of pathogens in the water and a decisive proof of fresh faeces contamination. Some of the drinking water sampled is considered not potable. It is therefore recommended that regular checks should be done on the pipelines to detect any leakages and do the necessary repairs.
