  The microbial water quality of three different coastal beaches located in the south coast of Madeira Island, were monitored from May to December 2005 (Formosa and São Roque), and from October 2006 to June 2007 (Gavinas). Total and fecal coliforms and enterococci counts in two of the beach sites, showed a seasonal dependence, with highest values in autumn and winter suggesting a positive relationship with rainfall and a negative relationship with temperature. Of the three sampled beaches, Formosa beach showed the highest water quality and São Roque beach the poorest water quality. Impacted freshwater discharges and deficient water circulation in this recreational zone could be the causes for the lower quality of this beach. However beach rating was shown to be dependent on the indicator microbe chosen. The results obtained emphasized the need of differential sampling strategi.. Read More»
