Resumen
In the fallowing academic essay, water quality from the artificial lagoon of the recreational park “Marco Romero Heredia” it is analyzed and diagnosed, according to the TULSMA regulation for water designated for secondary contact recreation. The trophic state is set through two indexes: OCDE and Carlson; the flow is determined by a bi-dimensional model; finally, treatment and maintenance alternative are presented.
Seven monitoring campaigns were performed between March of 2017 and January of 2018. The samples were taken to the Universidad de Cuenca’s sanitary laboratory for their respective analyses; the obtained results were compared with the parameters set by TULSMA regulation and the trophic state was obtained. According to this regulation, the water satisfies some standards, such as: dissolved oxygen saturation percentage, absence of greases and oils, surfactant agents, and pH levels; but others are not accomplished, such as: phosphorus/nitrogen relation, floating material, and coliform bacteria (in some measuring stations). The two indexes indicate an advanced level of trophy. Additionally. The bi-dimensional model generated showed that the velocities in the lagoon are too slow, besides in some zones the velocity is zero, because of this, there are static flow zones.
At least, recommendations are presented to improve and maintain a good water quality in the lagoon, as well as a periodic disinfection treatment that can be implemented to avoid eutrophication problems again, improving substantially the aesthetic of this lagoon.
