Effects Of Distribution Pipes On The Quality Of Drinking Water From The Central Borehole At The Ugbowo Campus Of The University Of Benin, Benin City (Nigeria)

Agatemor Christian, Ukhun E.Mark

The physico-chemical and microbial qualities of the drinking water at the central borehole at the Ugbowo Campus of the University of Benin was investigated and compared with the quality of the drinking water distributed from the borehole to different residential quarters and hostels in the campus. It was observed that significant changes occurred during distribution. The result showed significant increase/decrease for some parameters while some parameters showed no particular trend in the change. pH at the borehole was 5.01 while a range of 5.24 – 5.86 was observed at the residential quarters and hostels. Nitrate levels at the borehole (29.40 μg/l) were more than the levels observed at the quarters (ranged 9.40 – 23.08 μg/l). Parameters like phosphate showed no particular trend; while there was an increase at some quarters; decrease was observed at other quarters. Despite these changes, the overall quality of the water was within WHO and EU permissible limits and therefore fit for drinking and other domestic applications.
