All life depends on nitrogen, which is present in the atmosphere. However, too much nitrate-nitrogen in water can have a negative impact on living things. The most frequent anion to be found in groundwater is nitrate. Nitrate concentrations were monitored for water quality in different states and nations as part of a global groundwater survey. The concentration is often within the USEPA's 10 mg/L nitrate-nitrogen (45 mg/l nitrate, according to Bureau of Indian guidelines) guidelines. However, in a few isolated instances, water nitrate concentrations spiked, primarily as a result of the existence of landfills, septic systems, and solid waste disposal facilities. Consuming nitrate-contaminated water can have negative effects on humans, animals, and pregnant women. One such effect is methenaglobemia in young children. Different therapies have been used..
