The alteration of the environmental quality of the physical, chemical, biological and
microbiological characteristics of surface water bodies is the result of a useless number of
environmental factors associated with the development of a series of anthropogenic
activities of an industrial, commercial and domestic nature; These alter and affect the
natural composition of the body of water, causing one of the environmental problems of the
mayor transcendentalist at present. It is important to bear in mind that the consequences and
repercussions are reflected not only in affecting the biological and ecological potential of
the water body of influence, but also in turn reducing the quality of life of the social
component rooted around The affected zone Based on the above, there is a need to evaluate
the physicochemical and microbiological quality of one of the most important surface water
bodies in the state of the Atlantic: El Embalse del Guajaro; Which, is located in the
peripheral-rural area of the municipality of Repelón-Atlantic.
For the development of the following proposal, an experimental methodology was used
which comprises different stages in the execution process that began with a sampling
campaign in the study area, for reconnaissance and selection of stations taking into account
the geographical and topographic conditions ; Selecting 9 sampling stations corresponding
to the Guajaro Reservoir, and 8 stations corresponding to the Repelón Irrigation District,
from each one, point samples were taken and in situ parameters such as temperature,
dissolved oxygen, salinity, pH and conductivity were evaluated And a later phase in the
laboratory for nutrients, microbiological quality, and other parameters such as turbidity,
alkalinity, total suspended solids, chemical oxygen demand and biochemical oxygen
demand. The results of each station were evaluated by means of pictograms, maps in Surfer 11, to
carry out their due analysis, correlation and comparison with current Colombian regulations
and some international regulations, which allowed to identify the environmental conditions
of the body of water.
This analysis reflected the alteration and deterioration of the environmental quality of the
Reservoir and the District Channels, taking into account the physicochemical and
microbiological characteristics of the same, when compared to the normativity was
reflected that in some cases exceed the permissible limits established by activity as is the
case of Total and Fecal Coliforms. Thus, as a mitigation strategy for these pollution indices,
environmental management plans (EPAs) were proposed that allowed the evaluation of the
possible impacts caused by the anthropic activities to propose control measures to
contribute to the improvement of water quality and use efficient water resource.
