Nitrite and Nitrate
Compounds consisting of nitrogen and oxygen atoms; naturally occurring and help sustain plant and animal life
EPA MCLG Level
10 ppb
Maximum level that poses minimal health risk based on the latest science
Health Effects
Drinking water standards for nitrate and nitrite have been developed based on hematological toxicity observed in epidemiological studies. At elevated levels, these compounds have been shown to cause methemoglobinemia, also known as 'blue baby syndrome', a blood system disorder that is especially hazardous for infants and pregnant women. Nitrate and nitrite are frequently detected in groundwater and surface water.
Affected Organs & Systems:
Common Sources
- Ubiquitous in nature
- Released into drinking water in fertilizer, wastewater, and animal waste runoff
- Septic tank and sewage leakage are additional sources of nitrate in drinking water
- Nitrite may be released into drinking water by bacteria in stagnant pipes or during chloramination in drinking water treatment
How to Remove It
Water filters certified under the following NSF standards are effective at removing Nitrite and Nitrate:
EPA MCLG Level
The EPA MCLG represents the maximum level that poses minimal health risk based on the latest scientific research. It's often more protective than federal legal limits.
Contaminant Type
Nitrite and Nitrate is classified as a Inorganics contaminant.
This contaminant primarily affects the blood.
