The quality of water from any specific source can be evaluated by measuring physical, chemical and biological parameters. Those values, when compared with regulatory limits, determine the danger to human and ecosystem health. However, this technique can involve high costs and operational complications. Geographic Information Systems (GIS) are useful tools for evaluating environmental problems in a hydrographic basin, making strong estimates for the identification and analysis of possible impacts on water quality, based on in the holistic study of the environmental characteristics and dynamics of Land Use and Land Cover Change. The aim of this research was to analyze the environmental fragility of the Sinú river basin due to water resource contamination, as a tool for strengthening water governance and the water resources integral management. A water quality map by Inverse Distance Weighting (IDW) method was made from Water Quality Index (WQI) results. Afterward, an expert request was carried through the Analytical Hierarchical Method (AHP) to assess the environmental attributes that constitute the map. The results showed the Sinú river basin has a very homogeneous average quality throughout its trajectory, and the most fragile areas are located in the lower Sinú region. This is important to develop direct mitigation measures that allow ecological restoration promote adaptation to change climate and strengthen the integral water resource management.
