Diagnóstico de la calidad de agua de la microcuenca quebrada Las Delicias cerros orientales de Bogotá a partir de los parámetros químicos de acuerdo con la normatividad colombiana vigente

Resumen

In the city of Bogotá, water quality is one of the most important environmental and social problems due to its different economic activities that harm the surface waters of the city, one of those surface waters is the ravines delights located in the eastern hills In the year 1934, the Calderón Tejada forest neighborhood in the city of Bogotá is urbanized and deforested in an uncontrolled way, thus altering the creek, making it a dumping collector, thus forgetting its environmental and biological function (Secretary of Environment, 2013).Due to this concentration of populations where it interacts directly with the water system of the place (broken), these alterations have direct consequences of urban type, deforestation and both liquid and solid discharges, appropriation of rounds affecting water quality, thus generating a very lost serious diversity, landscape, environmental values and the loss of urban and city environment (Cifuentes & Luengas, 2018). Subsequently, a serious problem arises in this creek due to the poor disposal of both urban (domestic) and agricultural waste (use of fertilizers) that affect the quality of the water in the creek, being that surface waters such as rivers and streams they are vulnerable to different sources of contamination by both liquid and solid chemical substances, either of natural origin or of anthropic origin because water works as a vehicle for the transmission of pollutants, when consumed by the inhabitants of the area, These pollutants can accumulate in the body manifesting as diseases with slight consequences in some cases, but in other cases serious and lethal for the well-being of both the person and living beings that depend on the water in the creek. In turn, if the chemical properties of the water are altered can cause multiple negative impacts, one of them is the affectation to the aquatic flora and fauna preventing an optimal self-regulation of the organisms that work together to enrich nutrients thus reaching a multi-diversity of the aquatic ecosystem, alteration of the habitat for different species of animals and plants, loss of dissolved oxygen in the water since there are high concentrations of chlorides, nitrates and carbonates, this loss of dissolved oxygen changes the processes of water self-purification and consequently the death of life forms, loss of organic matter due to oxygen depletion in which it serves as nutrients for bacterial communities which are of vital importance for aquatic life. (Wu, 2009). In that sense, so that these alterations do not occur, it is necessary to analyze the chemical properties of water by means of parameters, statistical data collection techniques in the form of tables, indexes and laboratory practices for chemical parameters such as (pH, alkalinity, acidity, nitrogen , BOD, COD, phosphates, sulfates, chlorides, detergents, sodium, potassium, calcium, metals, among others), in order to ensure that the quality of the water is in good condition, and that it cannot affect either aquatic life or inhabitants who use water for different processes in their daily lives. Taking into account the foregoing, it is important to study and relate the chemical parameters of water with the quality of the water in Quebrada las Delicias in order to relate them to studies that were previously carried out in this stream by universities such as district, Manuela Beltrán and Mayor of Chapinero relating them to the studies related to tourism echo, and physicochemical characteristics of the creek in the ecological paths, in which they focused on the study of some parameters relating them to the current situation of the water quality of the ravine, linked to environmental sanitation and recovery activities of the ravine landscape.
