Abstract
Introduction. The microbiological contamination
level in the Combeima river. Objective. Was
determined in order to analyze its potential risks
for being consumed by humans, for recreation and
other uses. Materials and methods. From reports
of monthly average of total and fecal coliforms, by
samplings performed in the intake of its aqueduct
system between 2008 and 2012, plus its correlation
with the monthly average turbidity occurred. Besides,
during 2014 and during dry and rainy seasons,
water samples were taken in seven places located
throughout the river, in the upstream of the aqueduct
system´s intake. Results. The results obtained
show high microbiological contamination in the time
of the analysis and an evident increase downstream,
until waters arrive to the aqueduct system, and the
discharges of not treated waste waters are relevant,
including those with fecal coliforms from rural houses
and from livestock activities, especially pig and poultry
breeding. Besides, the changes in the river´s turbidity
influenced, mainly, the total concentrations of coliforms,
but were not relevant in the fecal ones. Conclusion.
In 2014, the dry season had a bigger microbiological
contamination compared to the rainy one, thus being
more hazardous for human consumption.
