Water

Etang de Berre is a coastal lagoon (eau de transition) with multiple sandy and pebbly beaches. The watershed includes tributaries: Arc, Touloubre, and Cadière rivers. Several wastewater treatment plants discharge into the basin and may contaminate bathing waters during malfunctions or severe storm events.

Location

Etang de Berre, France. Multiple beaches monitored including Robinsons (Rognac), Champigny, Marettes, Romaniquette, and others around the lagoon. Specific beach locations and parking information not provided in excerpt.

Season

Monitoring conducted May to September. Full seasonal data assessment completed at end of bathing season; profile updates required at least every 4 years for excellent quality beaches, every 3 years for good quality, and every 2 years for sufficient or insufficient quality.

Water Quality

Water quality classified into four categories: excellent, good, sufficient, or insufficient. Regulatory thresholds for intestinal enterococci and E. coli measured at the 95th percentile for excellent and good quality, and 90th percentile for sufficient quality. Robinsons beach: 2024 classification excellent; historical: 2021 good, 2022 excellent, 2023 excellent. Monitoring includes minimum 4 samples per season; classification based on current season and previous three seasons (minimum 16 samples).

Risks

Storm events cause short-term pollution; closure recommended for 24 hours after storms or heavy rainfall exceeding 10 mm in 24 hours. Three beaches identified as particularly sensitive to storm contamination: Champigny, Marettes, and Romaniquette. Wastewater treatment station discharge near Champigny beach identified as contamination source. Robinsons beach: 1 elevated discharge, 1 moderate discharge, 7 low-level discharges within 1000 metres.
