Where can black water be dumped?

The correct choice regarding where black water can be dumped is in the designated areas within the Contiguous Zone. The Contiguous Zone, which extends beyond a nation’s territorial sea, has regulations that allow specific kinds of waste disposal under certain conditions. This zone has particular legal frameworks that allow for the management of marine pollution, including black water, provided that all requirements are met.

In comparison, a Restricted Zone typically refers to areas where any type of dumping might be prohibited due to environmental protection laws or local regulations aimed at preserving sensitive ecosystems. Open sea areas, while seemingly a potential dumping ground, are often governed by stringent international marine pollution treaties that restrict waste disposal, including black water. Designated safe zones, although they sound appropriate, do not have the legal backing that the Contiguous Zone does for black water disposal.
