Waterborne diseases are illnesses caused by microscopic organisms, like viruses and bacteria, which are ingested through contaminated water or by coming in contact with feces.
Characteristics of Water
Subject and UNIT: Water Supply And Wastewater Engineering: Unit I: Water Supply
The coliform group of bacteria - Escherichia coli (E.Coli) is normally found in the intestinal tract of animals and human beings. E.Coli is not harmful, but its presence in water indicates the presence of other pathogenic micro organisms (like typhoid bacillus) in water
