Water

Douro River (water body code PTCOST3). Urban beach with extensive sand strip.

Location

Vila Nova de Gaia municipality. Monitoring point coordinates: Latitude 41.10306°, Longitude -8.66222°.

Season

June 14 to September 14, 2025.

Water Quality

Water quality is classified according to Decreto-Lei 135/2009 (amended by Decreto-Lei 113/2012). No days of bathing restriction or advisory occurred due to short-term pollution in the 2024 bathing season. Sampling frequency is every 3 weeks.

Risks

Faecal contamination may originate from the local sewerage network and the tributary ribeira de Atães. Short-term pollution is unlikely but may occur due to excessive flow of the tributary during rainfall events or discharge of untreated effluents from malfunction of the wastewater pumping station. Cyanobacteria proliferation potential is moderate with historical occurrence of blooms. Macroalgae and phytoplankton proliferation potential is low with no historical occurrence.
