Environmental context
The plant discharges into the Black Sea, a large inland sea connected to the Mediterranean via the Bosporus Strait. The Black Sea is highly sensitive to eutrophication due to its limited circulation and deep anoxic layers. The Varna Bay area supports diverse marine life and is an important ecological zone. Protecting water quality here is critical for maintaining the region's environmental health and tourism economy.
