Why is it crucial to monitor for ammonia in wastewater?

Monitoring for ammonia in wastewater is crucial primarily because it can be toxic to aquatic life. Ammonia is a form of nitrogen found in wastewater, and in elevated concentrations, it can have detrimental effects on various aquatic organisms. High levels of ammonia can disrupt the respiratory function in fish and other aquatic animals, leading to harmful conditions where they may experience stress, impaired gill function, or even death.

Furthermore, the presence of ammonia in water bodies can lead to serious ecological consequences, such as the disruption of the overall aquatic ecosystem and a reduced diversity of aquatic species. As such, wastewater treatment facilities must routinely test for ammonia levels to ensure that the treated water is safe for release into the environment, thereby protecting aquatic life and maintaining ecological balance.

While ammonia also plays roles in contributing to odor and color issues, serving as a precursor to nitrates, and indicating organic pollution, its toxicity to aquatic life is the most critical reason for monitoring its levels in wastewater.
