According to the surveys, this problem mainly affects surface waters and is generated basically for two reasons. On the one hand, the dumping of residential and industrial wastewater on bodies of water, without any treatment.                     On the other hand, the presence of solid waste on water, dragging of agrochemicals, leaching processes of solid waste from sanitary landfills and garbage dumps and events of oil spills.

The three main environmental problems that the respondents recognize at the local level are related to scenarios of water pollution (39.6%), air pollution (23.5%) and poor solid waste management (18.9%). Water pollution refers mainly to the alteration of the water quality of surface bodies due to the effect of liquid discharges and the disposal of solid waste generated to a greater extent by dwellings for home use (32%) and agricultural activities (16%) .

High levels of turbidity and total dissolved solids were found suggesting that the water in Colombia’s rivers does not have optimal conditions for the growth and reproduction of various aquatic organisms. In addition, high levels of fecal coliforms were found, associated with the existence of wastewater discharges, indicating that much of the water in Colombia’s rivers are not suitable for human consumption.
