Where does nitrates come from?

Where Do Nitrates Come From? There are numerous sources for nitrates that are found in groundwater. The largest sources are: septic tank wastewater, fertilizers (organic and chemical), decomposition of organic matter, and atmospheric nitrogen that is transformed to nitrate by soil bacteria.

What are the effects of high nitrates in water?

Nitrate can turn hemoglobin (the protein in blood that carries oxygen) into methemoglobin. High levels can turn skin to a bluish or gray color and cause more serious health effects like weakness, excess heart rate, fatigue, and dizziness.

Consuming too much nitrate can affect how blood carries oxygen and can cause methemoglobinemia (also known as blue baby syndrome).

Does a Brita filter remove nitrates?

Activated carbon filters, such as those in a “Brita” water pitcher, DO NOT remove nitrates.

Does spring water contain nitrates?

In a Houston study (Saleh et al. 2008), nitrate in bottled waters ranged from below the detection limit to 50.01 mg/L total nitrate, with spring water having the highest concentrations.

How high is too high for nitrates?

Although many aquarists run their tanks with extreme nitrate levels, the ideal is a maximum of 5 to 10 ppm. Levels of 20 to 50 ppm are too high.

Why nitrates are bad for you?

If there is an excess level of nitrates, plants and algae will grow excessively. An excess in the growth of plants and algae create an unstable amount of dissolved oxygen. During the day, there will be usually be high levels of dissolved oxygen, and at night the levels of oxygen can decrease dramatically.

What are the benefits of nitrates?

Nitrate (NO3) supplementation is associated with exercise performance, oxygen uptake, blood flow, and blood pressure improvement, and it can act as an antioxidant agent.

What are the long term effects of nitrates?

While it is recognized that research is limited, largely due to the complexity and cost of this type of research, some studies have shown a correlation between long-term ingestion of elevated nitrate and increased incidence of certain cancers, and increased birth defects.
