Physico-Chemical and Microbiological Analysis of Potable Water in Jericho and Molete Areas of Ibadan Metropolis

Abstract

This study was carried out to determine the quality of some water supplies in Jericho and Molete areas in Ibadan, Oyo State, Nigeria. A total of 6 water samples (Jericho and Molete) from well, borehole and public tap were randomly selected and analyzed in triplicate for some physico-chemical and microbial parameters. The pH ranged from 5.88 ± 0.01 to 6.88 ± 0.06 while total hardness ranged from 2.60 ± 0.04 ppm to 44.00 ± 1.20 ppm. The temperature ranged from 15.00˚C ± 0.07˚C to 18.00˚C ± 0.21˚C while conductivity ranged from 230 ± 1.15 to 460 ± 1.26 mho/cm. Alkalinity, Dissolved Oxygen (DO) and Biochemical Oxygen Demand (BOD) ranged from 4.03 ± 0.02 mg/l to 14.88 ± 0.15 mg/l, 0.4 ± 0.02 mg/l to 4.6 ± 0.02 mg/l and 12.80 ± 0.22 mg/l to 26.40 ± 0.72 mg/l respectively. Microbial analysis revealed that all of these water samples were not free from pathogens and thereby not suitable for drinking.

Quality Assessment of Waterside River, Ogbor Hill, Aba 1: Effect of Three-Point Samples on Some Hematological Parameters of Wistar Rats

“…Hard water reduced mortality from heart diseases 12 thus apparently supporting the relatively lower contamination load of the downstream sample as oted with the BOD, COD and OD results of this study and the inference thereto. High DO as noted in the downstream sample suggested lower pollution status 10 hence better water quality. Nevertheless, organic matter contamination of the three-point samples of waterside River, Aba was suggested due to the relatively lower COD value observed in this study compared to that (30 mg/L O 2 ) for Sokoto River.…”

“…In particular, high DO as noted in the Downstream sample suggested lower pollution status. 9,10 Generally, BOD, the amount of dissolved oxygen required for the biochemical decomposition of organic compounds and the oxidation of inorganic materials, particularly for the Downstream sample was higher than the EPA standard and 2.13 mg/L O 2 for Sokoto River. 11 The higher (p<0.05) TH (mg/L CaCO 3 ) of the Downstream sample (20.04±0.01) compared to the Midstream (0.99±0.00) and Upstream (0.61±0.00) samples though lower (p<0.05) than that for the standard (500.00) indicated that the samples were not, though the Downstream sample is more likely to be, hard.…”

Household drinking water quality and its predictors in flood-prone settings of Northwest Ethiopia: a cross- sectional community-based study

“…In rural locations where water sources are communally shared and exposed to several fecal-oral transmission channels in their local boundaries, bacterial contamination of drinking water is a primary cause of water-borne infections (Gwimbi et al, 2019). The contamination of the water can also be linked to the presence of pathogens such as fecal coliforms and Escherichia coli (Ladokun and Oni, 2015). They can therefore be viewed as a sign of fecal contamination and potentially declining water quality when found in drinking water.…”

Quality of household drinking water and its associated risk factors in flood-prone settings of Northwest Ethiopia: a cross-sectional community-based study.

“…Bacterial contamination of drinking water is a major contributor to water-borne diseases in rural areas where water sources are communally shared and exposed to multiple fecal-oral transmission pathways in their neighborhood boundaries (Gwimbi et al, 2019). The contamination of the water can also be traced to the presence of pathogens such as fecal coliforms and Escherichia coli (Ladokun and Oni, 2015). Their presence in drinking water can thus be seen as an indication of fecal pollution and possible deteriorating water quality.…”
