Diseño de un plan de manejo ambiental en la granja porcina "El Rosario" en la provincia de Tungurahua

Abstract

At El Rosario parish, located in Pelileo County, Tungurahua province, 15 minutes farfrom Ambato city, an environmental impact design was carried as a result of the pig production, this research was basedon the descriptive statistics, sewage samples, and the soil of the pig farm. Once theresults were analyzed they showed that to reduce the environmental impact generated by the contamination of sewage it is necessary to build water storage tankslocated 100 meters far away from the farm facilities in order to avoid the proliferation of unpleasantodors, improving the handling of solid and liquid waste. The physical and chemical water analysis reported DBO5 (Biological Osygen Demand), 10 and 1200 mg/L input and output data respectively. Regarding with the total solids the input value (460 ppm) is low related to the output value (4813 ppm). Among the mostrelevant negative environmental impacts which were identified with the use of Leopold matrix is the generation of unpleasantodors, contamination of water, and generation of waste corresponding to values of - 103, -88, and – 70 respectively; on the other hand the productive activity which generated the highest impact was the evacuation of sewage whit a value of -18. To decrease the environmental impact, it is necessary toapply the mitigation measures proposed in the environmental management plan, these measures will correct and guaranty that “El Rosario” pig farmaccomplishes the demands of then environmental regulations as well as the responsible use of the environmental resources.
