WESELUK, J.; VERGARA, F.  y  BERESTOVOY, V.. Water quality assessment of the Mboi Cae reservoir. Rev. cienc. tecnol. [online]. 2019, n.32, pp.1-10. ISSN 1851-7587.

The modification of the hydrological regime of the Mbói Caé stream was an important change in the city of Encarnación and surroundings benefiting the populations with the generation of hydroelectric energy, recreational activities, the availability of water, etc. The objective of this research is to analyze the water quality of the Mbói Caé reservoir in the Itapúa department through the Water Quality Index according to the Dutch Valuation System and the ICOTRO Contamination Index based on the total phosphorus concentration in the period November 2017 to September 2018. The results concluded that, taking into account the parameters of dissolved oxygen, biochemical demand of oxygen and ammoniacal nitrogen, the studied area is categorized with incipient contamination and, on the other hand, it is characterized as eutrophic by phosphorus.
