Estado del Río Bogotá en las estaciones de la red de calidad de aguas del IDEAM durante el periodo 2005 – 2014

Abstract

The report is the assessment of water quality Bogotá River in the period 2005 -2014 in the net of water quality IDEAM evaluating macroinvertevrados and physiochemical parameters in situ (conductivity, dissolved oxygen, pH, temperature) and ex situ (metals in water and sediment, BOD 5, COD soluble reactive phosphorus, total phosphorus, nitrate, nitrite, kjeldahl total sulfate and turbidity) at 14 stations, of which two are located in the Magdalena River with the intention of evaluating the water quality before and after the mixing point of these two bodies of water. As for the other twelve stations for the Rio Bogota, where the same parameters were analyzed in the Magdalena River, physico-chemical parameters and macroinvertebrates, with descriptive statistics (measures of centrality, dispersion and graphic positioning) Index Water Quality (ICA), BMWP / Col and Loads Pollutant Index. Under optimum conditions of quality, only you found the first station: Highway Bridge in the town of Villapinzón on the Bogota River, before the contribution of industries tanneries, the opposite happens in the San Pedro station after the municipality of Villapinzón, where he

7 has received contributions from tanneries generating one of the major problems of water quality along with Alicachín in Soacha and countryside in Girardot.
