RODRIGUEZ-TITO, José Carlos; PEREZ-SILVA, Rosa M; GOMEZ-LUNA, Liliana M  e  ALVAREZ-HUBERT, Inaudis. Chemical analytical and microbiological assessment of reservoirs Chalons and Parada from Santiago de Cuba. Rev Cub Quim [online]. 2017, vol.29, n.3, pp. 418-435. ISSN 2224-5421.

The quality of Chalons and Parada reservoirs was determined through physical chemical and microbiological parameters, taking as reference the obligatory and complementary indexes of the Cuban Standards related with main uses of water. For the analysis, 5 sampling points were selected in each reservoir, in March, May, September and November between 2011-2015. The determinations were made in situ and in laboratory, according to the current regulations. The totals Coliforms and fecal Coliforms were determined by the most probable number method (MPN/100 mL). The results concluded that the water quality of the reservoirs studied, from the physical chemical point of view, is adequate since all the parameters are within the levels regulated by the Cuban water standards. However, both reservoirs, according to these parameters, can be classified as eutrophic, which can compromise its quality from the microbiological point of view.
