Evaluación de la eficacia de la planta de tratamiento de agua potable Cariongo de la ciudad de Pamplona por medio de una comparación entre parámetros fisicoquímicos y microbiológicos de los afluentes que la abastecen y el agua tratada.

Abstract

Access to drinking water is essential for human beings on a day-to-day basis, which is why cities have water treatment plants. The city of Pamplona has the Cariongo drinking water treatment plant (PTAP), which is supplied from the Monteadentro and the Rosal streams. Currently, the plant operates continuously, but the effectiveness of the purification process carried out is not known since there is no record of the quality of the water to be treated. In order to elucidate the effectiveness, in this work the objective of evaluating the quality of the water of the hydric sources that supply the treatment plant and the water at the end of the purification process was raised; this from physicochemical and microbiological analyzes. For this, samplings were carried out in different parts of these water sources (high, medium and low), as well as samplings in different points of the distribution network. The results made it possible to characterize the different water samples, the color, turbidity, phosphates, iron and microbiological parameters such as fecal coliforms (Escherichia coli) and total coliforms (Citrobacter, Enterobacter and Klebsiella) being the most relevant characteristics due to due to its presence in large quantities in these water resources due to the anthropic activities carried out around these streams, in the same way, a great decrease in the parameters mentioned above is indicated when analyzed in the treated water, demonstrating the effectiveness of the water treatment plant. Finally, when calculating the risk index for the quality of water for human consumption (IRCA), it was determined that the raw water samples do not comply with what is required by Colombian legislation, so they were classified as water not suitable for human consumption. However, the drinking water samples did meet all the requirements stipulated in resolution 2115 of 2007.
