Résumé:
The aim of this study was to evaluate the organic load in a flooded area at the Federal University
of Campina Grande – UFCG, through the analysis of organic matter concentration in water. An
environmental investigation was conducted in the flooded area which receives industrial and
domestic liquid effluents. Through the recognition of the surrounded area, the survey of activities
carried out in the environment as potentials source of pollution and physicochemical
characterisation of wastewater, it was possible to quantify the organic load in the flooded area.
Consequently, it was possible to relate the effluent type and its origin in four analysed points.
Analysis of parameters such as pH, dissolved oxygen (DO), biochemical oxygen demand
(BOD5), chemical oxygen demand (COD) and temperature were carried out in the Sanitation
Laboratory of Federal University of Campina Grande. The released pollutants had a negative
effect on the water quality of the flooded area, mainly in reason of to the dissolved oxygen, where
due to high organic loads it may have consumed the available oxygen, hampering the process of
self-purification of the area. The analysed points suffer interference from outside effluents and
effluents produced by the activities conducted at the University.
