Environmental context
The plant discharges into the Charente River basin, which flows into the Atlantic Ocean near the Pertuis d'Antioche strait. This coastal zone supports extensive oyster and mussel aquaculture, making water quality critical for both ecosystem health and local economic activities. The area is also a key stopover for migratory birds along the Atlantic flyway.
