ABSTRACT
Comparative examination of three main sources of water supply in Independence layout Enugu was carried out with a view to determine their levels of contamination of bacteria. The sources of water examined are tap water, well water and stream water. The pour plate method was used to examine the water samples. Bacteria isolated from the water samples include coliforms especially Escherichia coli. Stream water and well water were found to contain bacterial isolates unlike the tap water that has none.
