The microbiological and organic pollutants characteristics of Owena dam in Ifedore local government area of Ondo-state, Nigeria was carried out, nine water samples were collected from three different parts of the downstream side, which include; around the waste disposal site, community settlement and farm environment. The microorganisms isolated were escherichia coli, enterobacter species, staphylococcus aureus, proteus species, streptococcus species, pseudomonas species and saccharomyces species. The presence and absence of micro-organism isolated from the dam water sample with their total aerobic microbial count (TAMC) and total yeast mould count (TYMC) value at each station were; station 1, 1065cfu/ml and 72sfu/ml, Coliform, E-Coli, Staphylococcus Aureus, Pseudomonas specie were present, Salmonella Typhi was absent.; station 2, 755cfu/ml 53sfu/ml, Coliform, Escherichia Coli, Staphylococcus Aureus, Pseudomonas specie, Salmonella Typhi were present.; station 3, 400cfu/ml and 25sfu/ml, Coliform, Escherichia Coli, Staphylococcus Aureus, Pseudomonas specie, Salmonella Typhi were present. The bacterial isolates; Escherichia coli ranges from 6.3% to 50.0%; Enterobacter species, 10.0% to 50.0%; Staphylococcus aureus 25.0% to 37.5%; Proteus species, 30.0% to 40.0%; Streptococcus species, 15.4% to 61.5%; pseudomonas species, 12.5% to 50.0%. For the fungal isolates, saccharomyces species ranges from 7.7% to 53.8%. The physiochemical parameters checked for in the dam water sample range is as follow: PH, 6.80; temperature, 25oC to 29oC; conductivity, 35μs/cm to 60μs/cm; total hardness, 0.3mg/l to 1mg/l; total dissolved solid, 58mg/l to 70mg/l; total suspended solid, 25mg/l to 120mg/l; dissolved oxygen, 4.0mg/l to 4.9mg/l; biochemical oxygen demand, 2.1mg/l – 4.4mg/l; nitrate, 27mg/l to 28mg/l; phosphate, 0.67mg/l to 1.52mg/l; sulphate, 110mg/l to 251mg/l; calcium, 10.7mg/l to 39.0mg/l. The microbiological and nitrate results showed that the dam water is contaminated and must be treated before consumption

ABSTRACT Water is one of the most important substances on earth. All plant and animals must have water to survive. If there is no water there would be no life on earth. Disease causing germs and chemicals find their way into water supplies when this happens, the water becomes polluted. The principal objective of this research work is to asses the... Continue Reading
