Routine checks on nitrate levels in treated water play a crucial role in ensuring compliance with environmental regulations. These regulations are established to protect ecosystems and public health, as elevated nitrate levels in water can lead to significant environmental problems, such as water quality degradation and the risk of human health issues when consumed. High levels of nitrates can result in conditions like methemoglobinemia, or "blue baby syndrome," particularly in infants.

Monitoring nitrate levels helps wastewater operators confirm that the treatment processes are functioning effectively and that the discharge meets the limits set by regulatory agencies. This practice is essential for maintaining sustainable water resource management, preventing pollution, and avoiding potential legal repercussions from non-compliance.

The other options do not address the primary purpose of monitoring nitrate levels. Increasing decorative aesthetics does not relate to nitrate monitoring, nor does avoiding water recycling or enhancing algae growth, which could lead to harmful algal blooms and further environmental issues. Compliance with environmental regulations ultimately safeguards both the environment and public health, making it the central reason for conducting these routine checks.
