Groundwater Contamination: Nitrate


Detecting and Treating Nitrate in Water

At U.S. Water, we believe in the importance of water that is not only abundant but also pure. Nitrate contamination in well water is a critical issue that can impact both the quality of your water and the health of your loved ones.

What is nitrate?

Nitrate (NO3-) is a chemical compound comprising nitrogen and oxygen. Although nitrogen is vital for plant growth, elevated nitrate levels in drinking water can pose serious risks to human health.

Where does it come from?

Agricultural Runoff: Fertilizers and manure used in agriculture can introduce nitrates into the groundwater.

Septic Systems: Poorly maintained or failing septic systems may contribute to nitrate contamination.

Industrial Discharges: Certain industries may release nitrates into the environment, impacting water sources.

Is it a health hazard?

High nitrate levels in drinking water, when consumed, can convert to nitrite in the body. This conversion interferes with the blood’s oxygen-carrying capacity, leading to a condition known as methemoglobinemia or “blue baby syndrome.” This is particularly concerning for infants and pregnant women.

When should I test?

Regular testing for nitrate is essential, especially for those reliant on well water. The U.S. Environmental Protection Agency (EPA) recommends annual testing for nitrate levels, and more frequent testing for pregnant individuals or those with infants.

If my water tests positive, what should I do next?

If your water tests positive for elevated nitrate levels, taking immediate action is crucial. Here are the recommended steps:

Cease Consumption: Avoid drinking the water until the issue is resolved. Use alternative water sources for drinking and cooking.
