The effects of burning tires on water quality in a section of the Piedras Blancas watershed was studied. Two samplings were conducted and their physicochemical and microbiological parameters were measured in order to obtain a pattern sample and a problem sample. The pollution level in the section of the basin studied was evaluated based on the water quality index (ICA, Spanish acronym), the National Sanitation Foundation Index (NSFI), and the Dinius Index. A comparative analysis of the indices demonstrated significant river deterioration from the burning of tires around the basin. The quality ranged from average to very poor, requiring treatment for human consumption and even specific treatment processes to remove hazardous pollutants such as phenolic compounds and heavy metals. In addition, the values of most of the parameters exceeded the acceptable limits established by Colombia’s environmental regulations on water for human and domestic use, preservation of wildlife, and livestock and agriculture. The results of this study indicate that the water’s physiochemical properties were greatly affected by the products that were generated by burning tires.
