This study presents some results of monitoring the beaches at East of Havana City, Cuba, during February and August corresponding to the rainy and less rainy seasons, respectively. For the bacteriological analysis were carried out 5 samplings in a period of 30 days, the rest of the samples was collected as punctual samples. The results are compared with those obtained in other samplings, specifically with 2004 period and with the requirements in the Cuban Standard NC: 22, (1999). Practically, the whole area showed pollution indicators deteriorated, such as: the permanganate oxidability value, bacteriological indicators and hydrocarbons, the last one corresponds to a lightly polluted area by
hydrocarbons. The most affected areas were the outlet of the rivers Guanabo and Itabo and
the lagoon with the same name, which is not beneficed by the circulation régime and are
occasionally affected by waste waters disposal.
The comparison with previous years indicate as general way a maintenance or increment in
the organic matter, nutrients and dissolved and dispersed hydrocarbons, as well as a slight
increase in the coliforms and fecal streptococcus concentrations Rincón de Guanabo area, considered as a protected area by the environmental authorities in Cuba was reported as a lightly contaminated area.
