Evaluación de la calidad de agua subterránea de pozos artesianos en los asentamientos de la parroquia San José de Morona, cantón Tiwintza

Abstract

The main objective of the current research work was to evaluate the water quality of artesian wells located in three communities of the “parroquia San José de Morona”, Tiwintza County. A sample was collected from each well during June that were subsequently analyzed according to physicochemical and microbiological parameters according to the NSF Water Quality Index (WQI) including nine assessment parameters such as: dissolved oxygen (% Sat O.D.), temperature change, pH, nitrates, phosphates, biochemical oxygen demand (BOD5), turbidity, total dissolved solids (TDS) and fecal coliforms. It used the IQA Data software in order to evaluate water quality. The obtained results are: PT-1= 68.37; PT-2= 61.40 and PT-3= 62.83, resulting in regular water quality at all points, and the parameters that influenced the three wells were nitrates, fecal coliforms and pH which are altered by anthropogenic activities and naturally. It concludes saying that the water from the artesian wells is suitable for human consumption and domestic use after conventional treatment. Finally, it is recommended that the inhabitants of the communities use good agricultural and livestock practices to protect the water sources.
