MARANON-REYES, Alina M et al. Temporal Evaluation for the Quality of Waters of the Los Guaos River of Santiago de Cuba. Rev Cub Quim [online]. 2014, vol.26, n.2, pp. 115-125. ISSN 2224-5421.

The lack of maintenance and inadequate operations and poor control and monitoring of water quality, and little introduction of cleaner production practices by major polluting entities have caused great pollution of major river basins Santiago de Cuba. Among them is the river's Guaos, which provides a high percentage of pollutant load to the Bay of Santiago. It is of great interest to conduct a study to evaluate the quality of the waters of this river, to establish their quality and potential use. Five monitoring stations were studied during the period from January to April. 23 physicochemical parameters were determinaro microbiological and 2. The results were compared with the Cuban Standards for drinking water supply, swimming and fishing and statistical methods were used for evaluation. According to the results, these waters are polluted from almost birth, which invalidates their use without treatment. They are affected by eutrophication.
