Determination of microbial level of environmental water used for consumption in selected areas of eastern senatorial district of Kogi state, Nigeria

The level of microbial activity in environment water used for consumption in Dekina, Anyigba and Ejule Districts in the Eastern Senatorial District of Kogi State were determined. Sample were taken from Agbano pond in Ejule, Kogi State University borehole, Anyigba, Oganaji River in Anyigba and Dekina River in Dekina. The physiochemical parameters such as particular matter, pH, Temperature and odour for each sample were taken. All samples were prepared using serial dilution. Colonies formation count was done using plate inoculation method at 37oc for 24 hours. The aerobic mesophilic for each sample was done using three media, (McConkey agar, M-endo agar and Eosin methylene blue agar). Sub-culturing were prepared for each sample and the Gram stain technique was used to determined the type of bacteria present in water. The catalase test were equally carried out. The results the rivers (Oganaji and Dekina) were highly polluted and contain more potent bacteria (Salmonella typhi) among others and hence pose a heavy health risk in the environment.
