Bacteriological assesment of drinking water from different sources in Kofar Yandaka Katsina, Katsina State
Microbiological analyses of drinking water samples from Kofar yandaka in Katsina metropolis were carried. The area was selected because of its dense population and the water used in the area were from different sources. A total of 15 samples (5 each) from well, jerry can and borehole were analysed. Aerobic plate count, coliform count and detection of some potential pathogens were carried out using standard procedures. The results obtained were compared with the standard recommended by WHO for drinking and recreational water. Aerobic plate count varied from 3.38x106cfu/ml in well water to 6.1x105cfu/ml in jerry can water. Most Probable Number (MPN) of coliform was found to range from 7+1.66 to 21+36.9 for all the water samples. Salmonella and E. coli were detected in both jerry can and well water. The aerobic plate count exceeded the acceptable limits and therefore indicates pollution of the water. The drinking of non-portable water in the area may expose the local community to the dangers posed by these sources of water.The study therefore stresses the need for the provision of safe drinking water to the area so as to avoid the risk of contracting water borne illnesses.
