Water Quality Index Assessment of Borehole Water in the Hostels in one of the Higher Institutions in Delta State, Nigeria

摘要

One of the greatest challenges of our time is to provide an adequate supply of potable water due to industrialization with its attendant pollution problems to water bodies. The aim of this research is to ascertain the potability of water samples from boreholes in hostels in one of the higher institutions in Delta State, Nigeria. It is also aimed at determining the water quality level using the water quality index. Water samples were collected and analyses using standard methods. The physicochemical parameters determined includes pH, Temperature, Acidity, Turbidity, Electrical conductivity, Dissolved Oxygen, Biochemical Oxygen Demand, Nitrates, Phosphates, Chlorides, Total Alkalinity, Total Suspended Solids, Total Dissolved Solids and Total Hardness. The results obtained were compared with WHO and SON standard and were found to be below the permissible limits which indicate their fitness for domestic purposes. The water quality index was also calculated using the water quality index calculator and values ranging from 76.19-78.02 were obtained which is regarded as good based on the water quality index legend.
