“…Both parameters are essential to assess the impact of human activities on rivers. The study carried out 15 on the physicochemical and microbiological evaluation of the water quality of the Machangara and Monjas rivers of the Quito metropolitan district (DMQ) water network is relevant due to its contribution to the identification of contamination levels in these rivers through the measurement of physicochemical and microbiological parameters. The information obtained through this study is helpful for decisionmaking regarding the management and conservation of the water of these rivers and, therefore, for the protection of the environment and public health.…”

The main objective of this article is to describe the pollution in the main Loreto-Coca rivers using physicochemical parameters. Our analysis is focused on the Orellana province and examines the Suno, Napo, Coca, and Payamino rivers, which are adversely impacted by oil and mining activities. These activities result in toxic and chemical residues, such as heavy metals and other contaminants. Samples were collected following the INEN 2176 standard to do this. We could evaluate parameters such as pH, dissolved oxygen, conductivity, turbidity, nutrients (nitrates, phosphates), heavy metals, and COD using laboratory equipment and specific techniques and methods. The level of pollution was determined by comparing these results with permissible limits. Therefore, based on the comparative results obtained, environmental education is crucial for raising awareness about the importance of protecting and conserving water as a vital resource. Conducting these studies provides essential information for taking preventive and corrective measures and monitoring and addressing identified issues to safeguard public health and the environment. Keywords: pollution, water, rivers, sample, standard, physicochemical parameters.

While urban river restoration has become mainstream in the Global North, it remains scarce in Latin America, where most literature focuses on water quality, stream habitats, and watershed assessment, but planning and implementation lag behind. Colombia is undergoing a paradigm shift after pioneering the integration of green and blue infrastructure (GBI) into urban planning in the early 2000s (namely Estructura Ecológica Principal). A surge in river renaturalization initiatives is underway, with large and intermediate cities planning and executing projects. We systematically assessed the integration of rivers and GBI into local policies (Planes de Ordenamiento Territorial) and found widespread and strong recognition of streams, wetlands, and ecosystem services in urban planning, higher than previously reported. Most cities emphasize river multifunctionality, ecological connectivity, public space, and recreation, as well as disaster risk reduction, advancing toward sustainable urban water and drainage systems. However, significant gaps persist regarding climate change resilience, participation, and social justice. In a region marked by high inequality, pre-existing spatial exclusion could be amplified by urban renewal, greening, and tourism due to unfair resettlement conditions and gentrification. Such trade-offs can undermine the ecological and social benefits of restoration. We highlight the crucial role of civil society and grassroots activism in protecting and defending urban commons and conclude by recommending a critical examination of GBI and river restoration efforts in Latin America. Colombia’s case can serve as both a reference and a cautionary tale for other cities in the region to achieve outcomes that promote equity and justice amid pressing social and environmental challenges.
