AVILA DE NAVIA, SARA LILIA and ESTUPINAN-TORRES, SANDRA MÓNICA. Bacteriological quality of the water of the humedal of Jaboque, Bogotá, Colombia. Caldasia [online]. 2006, vol.28, n.1, pp. 67-78. ISSN 0366-5232.
The water sanitary quality was evaluated of Humedal de Jaboque, like part of the project ecological restauration of the Humedal de Jaboque. There were chosen thirteen stations of sampling of the not canalized and canalized zone of the wetland, to evaluate possible temporary changes of the bacteriological quality there were realized four samplings that corresponded to the months of Octubre/2004, January, March and June / 2005. The method used for the microbial counts of the water was membrane filtration; the identification of the microorganisms was realized with rapid biochemical tests API-20 and Crystal BBL. The enumeration of the groups of bacteria (Aeromonas, Pseudomonas, Clostridium, total Coliformes and Enterococcus) did not show statistically significant differences between the stations that are in the canalized zone and those of the zone not canalized (ANOSIM, global test, R =-0.027, P> 0.05). To temporary scale the samples threw statistically significant differences between the months of sampling (ANOSIM, global test, R=0.511, P <0.05). For five groups of bacteria analyzed the minor obtained enumeration they happened in October, 2004. The groups of major abundance in the waters of the wetland are the total coliformes, Aeromonas and Pseudomonas, this behavior is observed both in the canalized zone and in the not canalized one, and in 4 months of the sampling, therefore, these three bacterial groups might be considered to be indicators of the sanitary quality of the water. The waters of Humedal de Jaboque contain a hight number of total Coliformes therefore they must not be used for human and domestic use, agricultural or recreative consumption.
