Background information and definitions
Untreated sewage reaching aquatic environments may impact marine and freshwater mammals through the introduction of bacteria, viruses and parasites, excess nutrients, toxic substances, and solid particles. Setting minimum sewage treatment standards, or improving the standards already in place, could potentially ensure that pollution levels and associated risks to marine and freshwater mammals are minimized. This may involve carrying out secondary or tertiary treatment of wastewater to further reduce pollutant levels.
