Caracterización fisicoquímica y microbiológica de los cuerpos de agua para uso agropecuario de las fincas que forman parte del proyecto agrosilvopastoril localizadas en la parroquia la belleza, provincia de Orellana

Abstract

This research refers to agricultural activity that is the main responsible for the pollution of water resources, due to the indiscriminate use of agrochemicals in crop production. Another activity that contributes to this pollution is livestock farming because the excreta of the animal are dragged to the water sources. This work responds to the objectives set out in the Agrosilvopastoral project, for which the physicochemical and microbiological characterization of the water bodies of the farms: Luis Prado, Heraldo Encarnación, José Cuenca and La Belleza, located in the parish of La Belleza, Province of Orellana, were performed. In order to determine if they are suitable for agricultural and livestock use. For this purpose, the analysis of 12 samples from the water from the riverbeds in the farms under study was carried out. The process of collecting and transporting the samples was carried out f in accordance with NTE INEN 2169:2013 standard. For the analysis of the following parameters: copper, iron, nitrites, nitrates, pH, total dissolved solids, sulfates, electrical conductivity, fecal coliforms and temperature, the methodology described in the Standard Methods and according to the HACH Method was followed. After interpreting the results, it can be indicated that iron and fecal coliforms in all the farms studied exceed the limits established in Ministerial Agreement (AM) 097-A, for livestock use. While in the La Belleza farm, the parameters: copper, pH and fecal coliforms are outside the limits established in the regulations for agricultural use. For the above, it is considered that the water bodies of these farms are not suitable for agricultural and livestock use, except for the water coming from the FJCTM1 point, from the José Cuenca farm, since all the parameters were found within the established limits.
