Abstract:

Nitrogen is present in atmosphere and is essential for all living things. However excess nitrate-nitrogen present in water can lead to adverse effects on living beings. Nitrate is the most common anion to be found in groundwater. Water quality monitoring in various states and countries conducted in groundwater survey around the world showed varying concentrations of nitrate. Most of the places, the concentration is within USEPA standards of 10mg/L nitrate-nitrogen (45mg/l nitrate according to Bureau of Indian Standards). However, some isolated cases showed spike in nitrate concentration in water mostly due to presence of wastewater disposal sites, landfills and septic/solid disposals. Consumption of nitrate contaminated water can affect livestock and humans especially babies and pregnant women such as methenaglobemia in infants. Various treatments have been found for removing ground nitrate from groundwater. Most cost effective and efficient method is adsorption.
