Introduction: The UN reveals alarming figures on projected water scarcity by the year 2050; it is expected to be a source of environmental and social conflicts, aggravated by urban sprawl, which causes deforestation, water pollution and habitat loss. Thus, the objective of this work is to apply Problem Based Learning (PBL) as an educational strategy to develop critical thinking and soft skills in university students. Methodology: Groups of three students were formed to collect field data with basic equipment, identifying active sewage discharges and other characteristics in the urban sections of the Malacatos and Zamora rivers in southern Ecuador. The information was processed in maps using GIS, to finally design water quality monitoring networks, frequency and parameters to be monitored. Results: The average grade achieved by the students was 8.6/10 and the degree of student satisfaction with the activity was 95% Discussion: These results indicate that the stated objective was achieved. Conclusions: The PBL methodology was effective, allowing students to apply their knowledge in water quality and other subjects; developing their professional competencies in a comprehensive and practical manner.
