Abstract
Objective: To discuss the use of coliform group bioindicators, highlight their employability and ideal characteristics for their use, as well as identify the microorganism that meets the desired standards. Results: It is understood that the inefficiency of sanitation, environmental and socioeconomic policies, combined with the use of contaminated water, food and poor hygiene of the population, because pathologies caused by microorganisms arising from fecal pollution. Due to the decline of water resources, in the search for assessments that verify the quality of water for consumption and recreation, microbiological bioindicators of the coliform group present in large numbers in feces of humans and homeothermic animals are used in order to verify if that water resource suffered contamination of water. fecal origin. Conclusion: It has been understood that the use of microbiological indicators is the most accessible and rapidly certifying way to identify faecal contamination, knowing that Escherichia coli is the bacteria in the group that best meets and meets the requirements for water quality assessment.
