Why are nitrates monitored in wastewater treatment facilities?

Monitoring nitrates in wastewater treatment facilities is essential because they serve as key indicators of nutrient levels in the water. High concentrations of nitrates can lead to water quality issues, such as eutrophication, which is the excessive growth of algae in water bodies due to the enrichment of nutrients. This can result in decreased oxygen levels, harming aquatic life, and potentially producing toxins that affect both wildlife and human health.

By tracking nitrate levels, treatment facilities can assess the nutrient loading into receiving waters and take appropriate measures to mitigate any adverse impacts. This is particularly important for protecting surface water sources that may be used for drinking water, recreational activities, and supporting ecosystem health. The management of nutrient levels, including nitrates, is a critical component of maintaining the overall water quality standards required by environmental regulations.
