ABSTRACT
Pollution of beaches in Latin America and the Caribbean, caused by uncontrolled
discharges of untreated domestic sewage, is a serious health problem for the
population. You must consider that there are three main sources of human fecal
contamination of sea water recreational use: domestic sewage, discharge of rivers and
other waterways, and directly Bather. This study evaluates the chemical quality of
beaches east. In situ temperature, salinity and pH measurements were made, the
chemical oxygen demand, ammonium, total nitrogen, inorganic phosphorus and Total
were determined. subsaturaciones oxygen were obtained in all seasons. Low
concentrations of organic matter were reported as well as nitrogen and phosphorus
which shows that eutrophication processes are not favorable. The low content of
inorganic nitrogen in both samples at the sampling stations located in the Rincon de
Guanabo, Guardafronteras, Agro-Guanabo and Mégano can lead to algae growth and
nitrogen-fixing bacteria.
