Evaluation of Water Quality Index Using Physicochemical Characteristics of Ogbor River in Aba, Abia State, Nigeria
The study was carried out to evaluate water quality index (WQI) of
Ogbor River, a freshwater system flowing through the commercial city of
Aba, Southern Nigeria using selected physicochemical parameters. The
levels of the physicochemical parameters were determined using standard
analytical procedures in the Laboratory. The values obtained were
subjected to statistical analysis using Excel spreadsheet (Version
16).Water Quality index was calculated using mean values of the
selected nine parameters and the World Health Organisation standard for
drinking water. The result of physicochemical parameters used showed
that Dissolved Oxygen (DO) with mean 4.44 \ub1 0.70 mg/L, and Nitrate
(NO3-) with mean 7.58 \ub1 6.25 mg/L were below National and
International standards. The value of WQI calculated was 83.05. The
result revealed that Ogbor River water quality was very poor, so it is
unfit for human consumption, and should be treated to avoid water
related diseases
