Item Evaluación Química del agua en una reserva natural para uso en la fabricación de compostaje(Universidad Santiago de Cali, 2020) Aponzá Múnera, Leydi Johana; Quintero Carabalí, Luis Alberto; López Parra, Lizbeth Lorena (Directora)The chemical evaluation was carried out in sampled waters in the Calima Reservoir reserve, located in the municipality of Darién, Valle del Cauca, determining chemical parameters (BOD, COD, Nitrates, Nitrites, Sulfates and Metals: Cd, Zn and Fe) in water, to be used in irrigation processes in composting. For this, samples were taken at nine points, at entrance 5 of Lake Calima, distributed between the shore, center and bottom areas of the reservoir. The samples were evaluated in triplicate, and the results were statistically treated, obtaining the following concentrations: Chemical Demand for Oxygen (20.2 mgO2/L), Biological Demand for Oxygen (3.8 mgO2/L), Nitrates (0.05133 mgN-NO3-/), Nitrites (0, 00500.0050 mgN-NO2-/L), Sulfates (3.7222 mg SO42-/L) and Metals (Cd =
