Resumen
Introduction. El Niño phenomenon causes
changes in the water quality of surface water
sources due to temperature increase and flow
reduction. Objective. To analyze the effect of el
Niño phenomenon occurring between the second
half of 2015 and the first quarter of 2016 on the
water quality of the Magdalena River, municipality
of Purificación (Tolima). The water analysis is
based on the characterization of its turbidity,
apparent color, pH, temperature, total hardness,
phosphates, nitrates, nitrites, chlorides, iron and
mesophilic microorganisms; to determine its
behavior before and during said natural event
characterized by loss of rainfall and its consequent
reduction of river flow, considered the one with the
greatest impact ever recorded. Materials and methods. Raw water samples were taken during
2015 and the first quarter of 2016 at the site of the
urban aqueduct of the municipality of Purificación -
Tolima. Results. Comparatively, during the months
of occurrence of El Niño phenomenon in relation to
the first half of 2015, water turbidity decreased and
the concentration of other indicators increased,
especially phosphates, nitrites and iron, which, as
dissolved substances, may pass the conventional
treatment process and be present in drinking water
in concentrations higher than those established by
current regulations. An increase in mesophilic
microorganisms was also evidenced. Conclusion.
During the occurrence of el Niño phenomenon, the
Magdalena river presented changes in its water
quality with an increase in some contaminants that
can pass the treatment process and imply risk to
human health.
