Water

Coastal bathing areas in Quiberon Bay. The coastline features an alternation of rocky outcrops and fine sandy beaches with peripheral zones.

Location

Carnac, Morbihan, Brittany, France. The municipality is bordered to the north by Ploemell and Erdeven, to the west by Plouharnel, to the east by Trinité-sur-Mer and Crach, and to the south by the Atlantic Ocean.

Water Quality

Contamination episodes were observed over the preceding ten years across all bathing and recreational foot-fishing zones in Carnac. A Type 3 vulnerability profile was established due to proven pollution risk, complex identification and evaluation of pollution sources, or unknown contamination causes. Water quality monitoring uses two bacteriological parameters: intestinal enterococci and Escherichia coli.

Risks

Proven pollution risk from multiple sources including collective wastewater systems, non-collective sanitation, stormwater networks, watercourses, and diffuse, point, or accidental pollution sources.
