The productive activities of 84 establishments that are settled in both margins of the Guaranda River were investigated, with a route of 4 km before it emerges and form the basin of the Chimbo-Guayas River. It was proposed to determine how water pollution occurs, specifically in the Negroyacu micro watershed of the city of Guaranda, Ecuador. In the course proposed for the study, georeferencing was divided into 9 areas with their respective sites of housing, crops, roads and vegetation. Zone four was the most polluting as a consequence of greater productive activity by trade and services; For the analysis of water samples in the laboratory the contamination was given by the presence of nitrates, chlorides and sulfates. It is concluded that the productive activities of the inhabitants of the studied microbasin correspond to the primary, secondary, tertiary and quaternary sectors. Commercial establishments discharge their wastewater to the micro watershed, and seven of ten establishments pollute the water. The presence of algae in zones one and two is an indicator of non-contamination of water. The indicators determine that it is necessary to implement water management actions to reduce pollution levels in the micro watershed.
