	Coliform Bacteria (Site not responding. Last check: 2007-10-20)
		If coliform bacteria are present in the water supply it is an indication that the water supply may be contaminated with sewage or other decomposing waste.
		Usually coliform bacteria are found in greater abundance on the surface film of the water or in the sediments on the bottom.
		The presence of coliform bacteria may be an indication of a polluted water supply but it would be necessary to do further tests in order to identify the specific bacteria present and the level of contamination.

		Fecal coliform bacteria are found in the feces of humans and other warm blooded animals.
		Fecal coliform bacteria enter water systems directly from mammals and birds, from agricultural and storm runoff carrying human and animal wastes, and from septic systems or combined sewer overflows.
		Since pathogens are difficult to detect in water, and a correlation exist between the presence of fecal coliform bacteria and the presence of pathogens, fecal coliform levels are monitored instead.

	Coliform Bacteria and Drinking Water - Office of Drinking Water water system management WA State Dept. of Health
		Coliform bacteria are organisms that are present in the environment and in the feces of all warm-blooded animals and humans.
		However, the presence of coliform bacteria in drinking water indicates that disease-causing organisms (pathogens) may be present in the water system.
		The presence of fecal coliform in a drinking water sample often indicates recent fecal contamination – meaning that there is a greater risk that pathogens are present than if only total coliform bacteria is detected.

	Coliform bacteria Summary
		Coliform bacteria are used often as an indicator of sanitary quality of foods and water.
		Coliform bacteria are defined as rod-shaped Gram-negative organisms which ferment lactose with the production of gas when incubated at 35 °C. These organisms are normally found in the aquatic environment and on vegetation.
		The presence of coliform bacteria in drinking water indicates that the water was not properly treated to eliminate pathogens, or that it became contaminated somewhere in the distribution system.

	US FDA/CFSAN - Enumeration of Escherichia coli and the Coliform Bacteria
		Coliform is not a taxonomic classification but rather a working definition used to describe a group of Gram-negative, facultative anaerobic rod-shaped bacteria that ferments lactose to produce acid and gas within 48 h at 35°C. In 1914, the U.S. Public Health Service adopted the enumeration of coliforms as a more convenient standard of sanitary significance.
		Fecal coliform, first defined based on the works of Eijkman (12) is a subset of total coliforms that grows and ferments lactose at elevated incubation temperature, hence also referred to as thermotolerant coliforms.
		Detection of coliforms is used as an indicator of sanitary quality of water or as a general indicator of sanitary condition in the food-processing environment.

		Public water systems are required to periodically monitor their water distribution system for the presence of total coliform bacteria to determine the sanitary quality of the water being provided to the public.
		Coliform bacteria do not generally cause disease by themselves, however, if they are found to be present in a water sample it is assumed that disease-causing organisms (pathogens) may also be present.

		These observations suggested that fecal coliform bacteria may have a natural refuge in tidal creek sediments, where they are shielded from harmful solar radiation, obtain needed nutrients, and find surfaces on which to attach and survive or even grow (Dale, 1974; Tate, 1978; Henis, 1987).
		Fecal coliform bacteria are ultimately produced in the guts of warm-blooded animals, entering estuarine waters by direct deposition, e.g., wading birds, storm water runoff, or leaks from waste treatment systems.
		Consequently, fecal coliform contamination of tidal creeks in New Hanover County may be driven by a complex relationship between storm water runoff, animal sources of fecal matter, and phosphate (and other nutrients) from fertilizers, all associated with residential land uses.
