Water-borne pathogen contamination in water resources and related diseases are a major water quality concern throughout the world. Microbial pollution in aquatic environments is one of the crucial issues with regard to the sanitary state of water bodies used for drinking water supply, recreational activities and harvesting seafood due to a potential contamination by pathogenic bacteria, protozoa or viruses. Some recent studies have shown significant correlations of microbial contamination with the risk of endemic gastroenteritis.^[1] Drinking water is a major source of microbial pathogens in developing regions, although poor sanitation and food sources are integral to enteric pathogen exposure. Gastrointestinal disease outcomes are also more severe due to under-nutrition and lack of intervention strategies in these regions. Poor water quality, sanitation and hygiene account for some 1.7 million deaths a year worldwide, mainly through infectious diarrhoea. Nine out of 10 such deaths are in children and virtually all of the deaths are in developing countries.^[2]

The following is the Microbial Contaminants — Contaminant Candidate List.^[3]

Microbial	Type	Diseases and Infections
Adenovirus	Virus	Respiratory illness and occasionally gastrointestinal illness.
Caliciviruses	Virus (includes Norovirus)	Mild self-limiting gastrointestinal illness.
Campylobacter jejuni	Bacteria	Mild self-limiting gastrointestinal illness.
Enterovirus	Viruses including polioviruses, coxsackieviruses and echoviruses	Mild respiratory illness.
Escherichia coli(0157)	Bacteria	Gastrointestinal illness and kidney failure.
Helicobacter pylori	Bacteria	Found in the environment capable of colonizing human gut that can cause ulcers and cancer.
Hepatitis A virus	Virus	Liver disease and jaundice.
Legionella pneumophila	Bacteria	Found in the environment including hot water systems causing lung diseases when inhaled.
Mycobacterium avium	Bacteria	Lung infection in those with underlying lung disease, and disseminated infection in the severely immuno compromised.
Naegleria fowleri	Protozoan	Parasite found in shallow, warm surface and ground water causing primary amebic meningoencephalitis.
Salmonella enterica	Bacteria	Mild self-limiting gastrointestinal illness.
Shigella sonnei	Bacteria	Mild self-limiting gastrointestinal illness and bloody diarrhea.
