This study was carried out during the months of January to March of 2019, samplings were made in the Babahoyo river in three different points; before, on the site and after the discharge of wastewater; In the process parameters such as pH, temperature and conductivity were measured in situ, in the same way the samples were conserved and preserved to determine physical-chemical parameters such as alkalinity, BOD5, COD, sulphates, nitrites, phosphate, suspended solids, total solids , fats and oils, total coliforms and fecal coliforms, CO2 and H2S. Based on the analyzed parameters, the pollution indices by mineralization, organic matter and suspended solids were evaluated. There was a low contamination index in the sampling site corresponding to the previous one, index of average contamination in the sampling site of the discharge, high pollution index in sampling site after discharge. Of all the parameters analyzed, those that exceeded the maximum permissible limits in the three sampling points were suspended solids, total coliforms and fecal coliforms. The concentrations found and the impacts generated by the discharge of direct residual water to the water resource are of concern, the other parameters they are within the maximum permissible limits, in comparison with the provisions of the Unified Text of Secondary Legislation of the Ministry of the Environment (TULSMA).
