Beach Closure: Algarve Struck by Contamination Incident
In the picturesque Faro district of Portugal, a recent incident of microbiological contamination has led to a temporary ban on swimming at two popular beaches - Praia da Alagoa-Altura and Praia Verde in Castro Marim.
On Monday, the city hall reported elevated levels of harmful bacteria, including E. coli, in routine water quality analyses. The exact source of the contamination remains unknown, but investigations are ongoing.
The State Environmental Agency (APA) communicated this information to the municipality at 12 p.m., prompting a swift response. A ban was declared on the beaches, with red flags placed as a warning to the public.
The municipality, in collaboration with official environmental and health agencies, has been working diligently to identify the source of the contamination. Although no definitive source has been found so far, a potential cause could be a sewage discharge from the Vila Nova de Cacela pumping station between July 27 and 31. This discharge is believed to have released contaminated black silt into a river that flows towards these beaches, causing the contamination[1][3][4].
The ban on swimming remains in effect until new results from further analysis are available. The city hall regrets any inconvenience caused by the situation and is hopeful that water safety and quality can be restored.
A follow-up water analysis conducted by August 6, 2025, showed that the contamination source no longer affected the bathing areas, allowing authorities to lift the swimming ban and replace red flags with green ones. The beaches were subsequently reopened, though investigations and monitoring continue to ensure water safety and quality are maintained[2].
This incident underscores the importance of regular water quality checks and prompt action when contamination is detected. It also demonstrates a coordinated approach by the authorities to identify, investigate, and resolve microbiological contamination incidents to protect public health.
