Water

Atlantic ocean bathing area. The water body is subject to tidal currents, with tidal reference points at Saint-Nazaire. Wave conditions include Atlantic swell, with simulations modeling westerly waves of significant height 3 metres. The beach experiences varying water depths across tidal cycles.

Location

Pornic, Loire-Atlantique, France. The beach is situated along the Atlantic coast in western France.

Water Quality

Bacterial quality of bathing waters has been monitored from 2000 to 2010. Water quality classification is assessed according to the 2006 directive standards. Potential pollution sources have been identified and hierarchized, including natural runoff, wastewater discharge, stormwater systems, diffuse agricultural pollution, and non-collective sanitation systems.

Risks

Identified pollution sources include coastal streams, stormwater discharge points, wastewater networks, diffuse agricultural runoff, and non-collective sanitation systems. Potential for macro-algae and phytoplankton proliferation has been assessed. Marine pollution episodes have been documented.
