Vila Nova de Gaia and Vila do Bispo are the municipalities with the most unpolluted beaches.
Zero System (Sustainable Land Association) has identified 71 beaches unpolluted in Portugal. This number means that it has not detected any contamination in the analyzes carried out over the last three bathing seasons. This represents 12% of the total of 579 bathing sites in 2016.
This unprecedented analysis of the Zero Association took into account the parameters of the legislation and concluded that there are 67 coastal bathing areas, 3 indoor and 1 transition (estuary) with zero pollution. Municipalities with the largest number of beaches in excellent environmental conditions are Vila Nova de Gaia and Vila do Bispo both six and Aljezur with 5 beaches. The islands were only represented by Santa Cruz, with just a beach, Garajau, which is a protected area.
Although it is extremely difficult to get a unscathed record over 3 years in the inland bathing areas, much more susceptible to microbiological pollution, there are 3 beaches in this situation: Rossim Valley in Gouveia, Fraga Footprint in Macedo de Cavaleiros and Zaboeira in Albufeira Castelo do Bode, in Vila de Rei.
From data obtained from the Portuguese Environment Agency, Zero Association identified the beaches along the three bathing seasons, not only always been rated "excellent" as they showed zero values or below the detection limit in all analyzes performed the two controlled and microbiological parameters of the legislation (Escherichia coli and intestinalenterococos). That is, in all analyzes made there was not even the detection of any colony forming unit.
Three warnings for the start of the bathing season
Zero selected three behaviors crucial for swimmers, or beach goers of the selected beaches for this early summer season 2016
First, for environmental and safety reasons, they should only be frequented beaches classified as bathing areas, where there is surveillance and where you know the water quality. Second, they should not be left any debris on the beach and preferably should direct them through the selective process. More than 80 percent of the 12.2 million tons of plastic entering the marine environment every year come from terrestrial sources, being the major contributor of waste plastic, including items such as beverage bottles and other containers. Finally, it must preserve the landscape and the surrounding ecosystems bathing water, avoiding the trampling of dunes or other sensitive areas.
