Análisis microbiológico y físico de aguas en el Laboratorio Ambitest SAS en Yopal - Casanare.

Abstract

The water supply in Yopal - Casanare is not optimal, therefore, it is necessary to monitor the quality of water. Therefore, Ambitest SAS Laboratory provides microbiological and physicochemical analysis services of drinking water, wastewater and wells. In the microbiological aspect, we analyze the presence of total and fecal coliforms, using the membrane filtration method for drinking water and swimming pools, while for wastewater and wells, we use the most probable number method. In the physical analyses, pH, temperature, electrical conductivity and turbidity are performed. Through the reports made in the months of March, April, May and June 2024, it is evident in the microbiological part of drinking water, non-compliance in 14 samples for total coliforms and in 3 samples for fecal coliforms in a total of 169 samples. In swimming pool water, total coliform growth was reported in 9 samples out of a total of 52, and in the physical analysis all samples comply with the regulations. In wastewater, total and fecal coliform growth was observed in all samples, as well as variability of data in the physical analyses, and for well water, total and fecal coliforms were observed in all samples reported, while in the physical analyses, there is regulatory compliance for temperature and turbidity, in pH there are samples below the permitted range, and in electrical conductivity analysis and reporting is performed. In the present work, both compliance and non-compliance with the regulations in force were evidenced, according to the reports of results obtained in the different water matrices analyzed. Through the reports made, the importance of the verification of water quality in Yopal - Casanare is contemplated, although for some parameters there are no limits established in the regulations, the monitoring of these waters minimizes the risks to human health.
