Abstract
The physicochemical evaluation of water from the Alulu River in the
Abakpa Nike Axis of the Enugu East Local Government Area in Enugu State is
presented in this study. Methods such as gravimetric and titrimetric analysis
were performed. The results show that the water's pH (6.37) is low, which means
that it is acidic and should not be consumed because it is much lower than the
6.5–8.5 WHO norm. The water sample contains a minor number of ions, as
indicated by other calculated metrics like conductivity (90.5 µS/m).
Additionally, the sample's colour (430 Pt-Co) and high turbidity (44 NTU) have
been adversely affected by the high concentration of total dissolved solids
(580.7 mg/L) in comparison to the permissible level of 500 mg/L. Because of the
relationships between turbidity, conductivity, and colour, a greater TDS will
also result in a higher turbidity level. Additionally, at the time of sample
collection, the surrounding air temperature was approximately 25 0C,
but the water sample's temperature was found to be 30.5 0C. This
high temperature is the cause of the water's high turbidity because more
substances will dissolve at a higher temperature, which will affect the water's
turbidity. Moreover, even while the 5 mg/L of chloride is within the W.H.O.
standard, it may not be sufficient to meet the demands of organisms for
chlorine because it is so small and does not pose a health danger to any
aquatic community. This minute concentration might have resulted from the
significant amount of water present during the sample collection period because
of the extended rains. Since the concentration of nitrate could not be
determined by the analytical technique employed, it was below the detectable
limit. Another reason for this can be the time of year the sample was taken.
Prolonged rainfall and a significant amount of water are the hallmarks of the
rainy season.
