Caracterización Físico- Química Quebrada Las Delicias "Sendero Ecológico Quebrada Las Delicias"

Abstract

The physical-chemical characterization broken The delights "Ecological trail broken the delights", has as objective characterize physicochemical parameters of water quality, samples and analysis of samples in 5 sampling campaigns; in this way, obtain own and specific data of the actual state of the channel, to determine, relate and make a diagnosis through previous studies of public and private entities. The area of influence is located in the town of Chapinero in the city of Bogotá DC, in the Bosque Calderón Tejada neighborhood from January to February 2017, in the section of the elevation 2900 masl (slope of the mountain, upstream of the last direction registered Transv 5 this # 58a - 53) at 2700 masl (downstream at the end of the ravine by channeling in Aven. 62 # 2 - 20). The determination of the selected parameters was made in situ and ex situ (laboratory) in five points distributed throughout the area of influence; 1). Well-waterfall at 2900 m.s., 2). Waterfall The Virgin, 3). Artisanal bridge, it is immersed inside the human settlements, 4). Culmination of the Bosque Calderón Tejada neighborhood, 5). Upstream of the retaining wall (spillway) and 6). Downstream of the retaining wall (spillway). The process was developed, taking into account good sampling practices (GMP) and good laboratory practices (GLP). The physicochemical parameters evaluated correspond to pH, ambient temperature, water temperature, electrical conductivity, turbidity, dissolved oxygen (DO), profile of solids (settleable solids and total dissolved solids), iron and fats and oils. Decree 1594 of 1984 of the Ministry of Environment and Sustainable Development establishes the admissible quality criteria for the destination of the resource for the preservation of flora and fauna in Article 45. It was evidenced that the quality of the water is optimal, since it does not represent danger, in its great majority this is under the permissible limits, nevertheless, it is clarified that the pH compared with the previous studies if it has a significant and medium and long change The term can have a significant, "negative" impact on the stream as it increases the pH toward basicity.
