Evaluación de los componentes microbiológicos y fisicoquímicos de los cuerpos de agua con potencial de fitorremediación de los diferentes humedales ubicados en la localidad de Bosa y Kennedy

Abstract

Wetlands are fundamental ecosystems for water regulation and conservation of flora, fauna and avifauna of the capital, over the years these have been affected mainly by demographic expansion and ignorance of their complex structures and importance, thus, this research aims to generate an assessment of the microbiological and physicochemical components of the water bodies of wetlands in the town of Bosa: Tibanica and La Isla and of the locality of Kennedy: Vaca sur, norte and Burro, that allows evaluating the current state of the water bodies present in them, in order to analyze the phytoremediation potential of the species Eichhornia crassipes in the improvement of the water quality of these wetlands, since this floating macrophyte, due to its structure, represents an alternative in the removal of contaminants and constitutes an option for the management of the same, which due to its rapid growth is invasive for the ecosystem. In the present study, after three weeks of the initial assembly of the samples of the water bodies of the five wetlands of the locality of Bosa and Kennedy, percentages of reduction of the microbiological parameters total coliforms and E. coli, as well as of the physicochemical parameters of BOD, COD and salinity, increase of others such as pH, STD, turbidity, conductivity, which shows the phytoremediation potential of the mentioned species, as well as an increase in the weight of the plant and a decrease in the amount of water, due to the natural process of the plant and evaporation. On the other hand, it is evident that according to decree 1594 of 1984, the waters of the five water bodies do not comply with specific parameters of the norm according to the use of wetland water.
