Abstract

Water Microbiology deals with the study of the living organisms of microscopic size present in water that causes infectious diseases of man. The primary test performed on water taken from 10 different sites act as an indicator of different types of water pollution especially faecal pollution of water due to the presence of coliforms bacteria because they are invariably present in faeces of human beings. The safety of drinking water is an ongoing concern within the global village. Traditionally, the safety of potable water supplies has been controlled by disinfection, usually by chlorination and coliform population estimates. However, it has been reported that coliform-free potable water may not necessarily be free of pathogens. Some diseases causing microorganisms enter water from different sources and causes different types of diseases such as Polio, Typhoid, Hepatitis, Shigellosis, Salmonellosis can spread through this contaminated water which is a matter of concern.
