EVALUATION OF MICROBIOLOGICAL DATA FROM THE SANITARY SURVEILLANCE OF WATER CONSUMED IN QUIRINÓPOLIS, GOIÁS

Abstract

Water is essential for human survival and health and microbiological monitoring of the water supply is a practice used to control fecal contamination and prevent diseases. The objective of this study was to evaluate data on the parameters Total coliforms and Escherichia coli (E. coli) in the water supply for human consumption in the city of Quirinópolis, Goiás, observing the standards recommended by Ordinance GM/MS No. 888/2021 of the Ministry of Health. The secondary data provided by the Health Surveillance were evaluated and mapped in the period from 2021 to 2023. A total of 524 water samples were collected in 34 neighborhoods. The results showed annual microbiological percentages above the allowed standard with the presence of total coliforms in the samples collected during the three years. And for the E. coli bacterium  in 2021 and 2022, with the exception of 2023, noting an evolution in the microbiological quality of the water. The mapping showed the central region as the most contemplated with water sample collections and with the highest number of presences for total coliforms in the three years and E. coli in 2021 and 2022. Although the microbiological quality of the water improved in relation to E. coli, the same did not happen with total coliforms in 2023. For this reason, it is suggested that there is a need for in-depth investigation and additional monitoring, with an increase in the frequency of sampling in the most compromised neighborhoods, so that it can predict vulnerabilities in the supply and specific preventive actions, meeting the recommendations of the current legislation in Brazil.
