Abstract:
Microbiological and chemical quality of drinking water primarily results from water origin and
type of applied water treatment. many infectious agents can be transmitted to humans through
drinking water causing waterborne diseases, regular monitoring of drinking water quality in
water supply systems is needed. This study investigates the microbiological quality of tanker
water supplied to selected different local communities(Atta, Amaraku, Abajah) in Imo state
during summer, Rainy and winter season for the period of the year June, 2017 to June, 2018.
Since increased concentrations of some chemical compounds in water can influence on
appearance and growth of microbiological populations, in this study relevant physicochemical
parameters were also measured and correlated with obtained values of analyzed microbiological
parameters. Physico-chemical parameters studied includes determination of the pH, temperature,
turbidity, hardness, alkalinity, chlorides, fluorides nitrate, iron, silica levels in the water samples.
The results obtained indicated that the chemical quality of the water samples under study falls
within the standards recommended by World Health Organization. However, more potentially
dangerous discovery was the level of Coliform contamination which exceeds the WHO
standards. Other microorganisms detected were E. coli, Enterobacter, Salmonella, Pseudomonas.
This can result in high incidence of water-borne diseases such as Dysentry, Diarrhea and
Typhoid fever. |
