What is E. coli?

Escherichia coli or E. coli is a type of fecal coliform bacteria that is commonly found in the intestines of animals and humans. While not a health threat in itself, it is used to indicate whether other potentially harmful bacteria may be present. E. coli in water is a strong indicator of sewage or animal waste contamination. Sewage and animal waste can contain many types of disease-causing organisms. The abundance of E. coli in water is commonly reported in terms of MPN, which stands for most probable number and is the statistical outcome from a series of measurement steps used to determine number of organisms present in a water sample.
