Nitrate (as NO3)
Nitrate (NO3) is a chemical compound that consists of one nitrogen atom and three oxygen atoms. It is commonly found in fertilizers and can enter drinking water supplies through agricultural runoff, wastewater discharge, and natural deposits in the soil.
EPA MCLG Level
45 ppb
Maximum level that poses minimal health risk based on the latest science
Health Effects
High levels of nitrate in drinking water can lead to health issues, particularly for infants and pregnant women. It can cause methemoglobinemia, or 'blue baby syndrome,' which affects the ability of blood to carry oxygen. Long-term exposure may also be linked to other health risks, including certain cancers.
Affected Organs & Systems:
Common Sources
- Agricultural runoff
- Fertilizer application
- Wastewater discharge
- Natural deposits
