The water quality index (WQI) incorporates physicochemical parameters in an equation to determine the quality of the water in a fixed place and time. Objective. Analyze the water quality index of the Guaymaral sector, temporally and spatially, using two methodologies to measure calculations: UWQI and CWQI. Materials and methods. A temporal-spatial comparison was performed between August 2015 and April 2016, selecting four sampling points and monitoring physicochemical parameters in four different seasons. Results. Most of the points sampled were assessed by ICA-UWQI as fair, and by ICA-CWQI as poor. Conclusions. From the two methodologies, it was determined that the UWQI is ideal to rapidly evaluate some specific use of the water, since it allows immediate decision making, while the CWQI is ideal for temporal-spatial evaluation studies.esCorporación Universitaria LasallistaÁrea Metropolitana del Valle de AburráÍndice de Calidad de Agua (ICA)Calidad del aguaHumedal Torca - GuaymaralParámetros físicoquímicosDeterminación del Índice de Calidad de Agua para el sector occidental del humedal Torca-Guaymaral empleando las metodologías UWQI y CWQIDetermination of the water quality index for the western section of the TorcaGuaymaral wetland using UWQI and CWQI methodologiesDeterminação do Índice de Qualidade da Água para o setor ocidental da zona úmida Torca-Guaymaral empregando as metodologias UWQI y CWQIArticle
