Guidelines for Canadian Drinking Water Quality: Guideline Technical Document – Ammonia

The production of ammonia is a normal part of metabolism, and levels occurring in the human body from metabolic processes generally exceed concentrations found in drinking water. The concentration of free ammonia entering the distribution system can lead to nitrification and the potential increase of nitrate and nitrite in drinking water. This guideline technical document reviews and assesses all identified health risks associated with ammonia in drinking water.
