Coliform counts was more than 500 times the norm.

Coliform procedures are performed in aerobic or reduced oxygen conditions.

Coliform bacteria and fecal matter may also be detected in runoff.

Coliform bacteria, of which E. coli are one type, are found about 80 times a year in the system, city officials said.

"And we found plenty of fecal and coliform bacteria."

Coliform bacteria are a commonly used bacterial indicator of water pollution, although not an actual cause of disease.

Coliform bacteria are a commonly used bacterial indicator of sanitary quality of foods and water.

Coliform bacteria is not harmful itself, but its presence indicates that other bacteria that do cause disease may be present.

Coliform bacteria are microorganisms that primarily originate in the intestines of warm-blooded animals.

Coliform bacteria have appeared in some area water samples, she said, referring to the bacteria resulting from untreated sewage.

Coliform bacteria and E. coli are commonly-used field indicators of fecal contamination by animals (including human).

Water testing in May 2006 said there are Coliform bacteria in four wells in Carlisle.

Coliform bacteria formulation (e.g. Escherichia coli)

The state Health Department recommends that local officials consider a beach shutdown when more than 20 percent of samples taken exceed 5,000 coliform bacteria per 100 milliliters.

Because giardia and cryptosporidium form protective cysts, they are far more resistant to disinfection than coliform indicator organism and bacterial pathogens.

Coliform index measures the population of an organism commonly found in the intestines of warm-blooded animals as an indicator of the possible presence of other intestinal pathogens.

The Coliform index and waterborne disease: Problems of microbial drinking water assessment E&FN SPON: London.

Coliform organisms ferment the lactose in this medium, producing a red colour (i.e. Escherichia coli), whereas non-lactose-fermenting organisms produce clear, colourless colonies, i.e. Salmonella sp.

Coliform bacteria in water samples may be quantified using the most probable number (MPN) method, a probabilistic test which assumes cultivable bacteria meet certain growth and biochemical criteria.

"There'll be coliform bacteria, aerobes, anerobes, in that," Dr. Jay Boyer said, looking at the water samples we took of the scum in the New Rochelle Harbor.

The County Department of Health last summer closed Westchester's public beaches 12 times after heavy rainfall when sewage plants became overloaded and coliform bacteria levels in the water rose, indicating possible fecal contamination.

Bird droppings under piers raised coliform bacteria counts and closed swimming areas, dead dolphins started washing ashore around July 1, sewage system breakdowns fouled beaches and a mysterious 50-mile-long tide of hospital waste forced additional beach closings.

Coliform bacteria selected as indicators of fecal contamination must not persist in the environment for long periods of time following efflux from the intestine, and their presence must be closely correlated with contamination by other fecal organisms.
