What is Ammonium?

Ammonium, represented by the chemical formula NH4+, is an onium cation obtained through the protonation of ammonia (NH3). This process involves the addition of a hydrogen ion (H+) to an ammonia molecule, resulting in the formation of ammonium. Ammonium plays a critical role in various biological and ecological systems. It serves as a vital source of nitrogen for plant nutrition and is involved in the nitrogen cycle, which is essential for life on Earth. Additionally, ammonium is found in a wide array of organic and inorganic compounds, including many fertilisers, where it aids in providing the necessary nutrients for plant growth. Its presence in different environments, from soil to water bodies, underscores its importance in both natural and human-made processes.


Ammonium in Potable Water

Ammonium, a compound derived from ammonia by the addition of a hydrogen ion, is frequently encountered in both natural and treated water sources. While not commonly measured in drinking water, its presence can signal potential issues, particularly in groundwater, where it may originate from agricultural runoff, industrial waste, or natural processes. Despite its potential to indicate contamination, current research and guidelines suggest that ammonium at the levels typically found in drinking water does not pose an immediate health risk to humans. However, its presence can influence water treatment processes, such as breakpoint chlorination, which is utilised to remove high concentrations of ammonium effectively. This method is noted for its efficiency and minimal spatial requirements, highlighting the importance of managing ammonium levels to maintain water quality. Moreover, while ammonia and its derivatives like ammonium are used in various applications, including cleansing agents and food additives, their regulation in drinking water focuses on ensuring safety and preventing negative impacts on both human health and water treatment systems. Thus, monitoring and managing ammonium levels in drinking water is crucial for safeguarding public health and maintaining the effectiveness of water treatment protocols.
