Evaluación de la calidad física, química y microbiológica del agua potable del catón Palora, provincia de Morona Santiago.

Abstract

The purpose of this research work was to evaluate the physical, chemical and microbiological quality of the drinking water of Canton Palora, Province of Morona Santiago, to determine if it is suitable for human consumption. Sampling was carried out during the period OctoberDecember 2016 and 12 samples were collecte dat different representative points corresponding to the entrance of the Plant that connects with the Numbayme River, a quick mixing tank, four of chlorination, two tanksOf reserve, two entrance valves of water: one to the canton Palora and another to the sector known as Mojon, three Palora homes distributed in three networks (high, medium and low) and two domiciles of El Recreo, the analyzes were performed in duplicate.

The physical-chemical analyzes were carried out in the Water Quality Control Laboratory at the Sciences Faculty of the Escuela Superior Politecnica of Chimborazo, except for the residual chlorine test that was carried out in situ, the Standard Method was used to examine the water. Respecting to the microbiological analysis, it was performed by the most probable number method. As a conclusion, was shown that the water of the Canton Palora, is not suitable for human consumption, because the pH parameters were below the maximum limit allowed and those of phostate above the maximum limit allowed according to the norm, therefore it is recommended an adequate and continuous maintenance to the treatment plant.
