What is Nitrate and Nitrite in Water?

Nitrate and nitrite are chemical compounds that contain nitrogen and oxygen. They are commonly found in water due to the breakdown of organic matter and nitrogen-based fertilizers. Nitrate is a naturally occurring compound found in soil and water and is an essential nutrient for plants and animals. Nitrite is a compound formed when nitrate is reduced or when certain bacteria break down organic matter. Nitrite is generally not found naturally in water, but it can be present in certain rock and soil types. Nitrate and nitrite can enter the water through the leakage or runoff of nitrogen-based fertilizers, the decomposition of organic matter, and releasing sewage or other contaminants into the water. Nitrate and nitrite can also be found in certain water treatment chemicals. The nitrate and nitrite levels in water are typically measured in parts per million (ppm) or milligrams per liter (mg/L). The maximum contaminant level (MCL) for nitrate in drinking water is 10 ppm, while the MCL for nitrite in drinking water is 1 ppm.

Symptoms of Nitrate and Nitrite in Water

Nitrate and nitrite in water are generally not detectable by humans, as they do not have any noticeable taste, smell, or appearance. However, high nitrate and nitrite levels in drinking water can harm human health, especially for young children and pregnant women.

Exposure to high levels of nitrate and nitrite can cause a condition known as methemoglobinemia, which is characterized by the inability of the blood to transport oxygen to the body's tissues. Symptoms of methemoglobinemia may include dizziness, fatigue, shortness of breath, headache, and blue or gray skin and nails. In severe cases, methemoglobinemia can cause coma or death.

It is important to regularly test your water for nitrate and nitrite to ensure that it meets safe and acceptable levels. If you are concerned about the levels of these chemicals in your water, it is important to have it tested and, if necessary, implement appropriate treatment methods to remove or reduce the concentration of nitrate and nitrite in the water. If you suspect that your water may contain high nitrate or nitrite levels, you should seek medical attention immediately.

Treatment of Nitrate and Nitrite in Water

Two methods for treating nitrate and nitrite in water are ion exchange and reverse osmosis.

• Ion exchange is a process that involves passing water through a bed of ion exchange resin, a porous material coated with charged particles. The resin is designed to attract and remove specific ions from the water, such as nitrate and nitrite ions. Once the resin becomes saturated with ions, it can be regenerated by passing a salt solution through the bed, which removes the ions and replenishes the resin's capacity to remove more ions.

• Reverse osmosis is a process that involves forcing water through a membrane that is designed to remove specific contaminants, such as nitrate and nitrite. The membrane is made of a thin layer of a semipermeable material, which allows water molecules to pass through but blocks larger molecules and contaminants. Reverse osmosis can effectively remove nitrate and nitrite from water, but it requires a high-pressure pump and a special membrane filter to operate properly.

The best method for treating these chemicals will depend on the specific circumstances and the water’s nitrate and nitrite levels. It is also important to regularly test your water to ensure that it meets safe and acceptable levels of nitrate and nitrite and to make any necessary adjustments to your treatment system. A Penguin Water Systems certified water specialist can assist you in determining the most effective method for removing nitrogen from your water. These specialists have the knowledge and expertise to assess your water's specific characteristics and recommend the most appropriate treatment method based on your unique needs. They can help you identify the best method for addressing nitrogen in your water and ensure that it is safe and high-quality. By working with a certified water specialist, you can be confident that you are making an informed decision about your water treatment and taking the necessary steps to address any water quality issues you may have.
