ABSTRACT The present research work was carried out based on an integrated analysis in the Chonta River basin, located in the districts of Baños del Inca and La Encañada, province of Cajamarca, in Peru. Framed in the use of communities of benthic macroinvertebrates as biological indicators, together with the evaluation of physicochemical parameters in the main channel of this basin (Chonta River), since during the last decade it has been affected by anthropic activities due to the dumping of wastewater without previous treatment. To assess the environmental condition of the Chonta River, two temporalities of study were established (Wet Season and Estuary), analyzing 22 environmental variables (in each season) and the benthic fauna was collected using the qualitative method (identification of organisms up to the taxonomic level). of family), with the collection technique through the D-net network. In order to study the relationship between the macroinvertebrate communities and the physicochemical variables, different statistical analyzes were carried out. Likewise, the environmental variables were compared with the Environmental Quality Standards for Water Category 3 (Categorized by the National Water Authority of Peru) and the BMWP / Col Index was used to assign quantitative values to the communities of benthic macroinvertebrates, in this sense, the parameters that most affect the benthic community were identified through a linear regression. The results that were obtained indicated that the distribution and benthic composition is determined by the variation of the physicochemical parameters defined by the environmental degradation. It was concluded that the methodologies applied for the study of the Chonta river were appropriate to determine its water quality, which was found in a range of moderately polluted in the six sampling points for the wet season and four first points for the dry season, and presenting contaminated water in the last two points of the dry season; which indicates a greater anthropic intervention as the river bed approaches the cities, where there is greater industrial activity and evidences the inadequate management of water resources.
