How are your water’s Nitrate Levels?

Nitrate (NO3) is a compound that contains nitrogen and oxygen and is known as a salt.

Nitrogen is released by decomposing material such as plants, human and animal wastes. Nitrates are essential for plant growth as they facilitate the production of amino acids and proteins.

Nitrate is highly water soluble and excess nitrate, not used by plants, can leach through soil into groundwater. Other sources of nitrate in water include fertilizer and industrial discharges.

Nitrate is a water pollutant and affects plant growth. It can also affect existing plants and animals. Excess nitrate in water is a cause of eutrophication, which is when too many nutrients get into water bodies, causing excessive plant growth. This large amount of plant growth effectively steals oxygen from the water, causing fish and other aquatic life to die.

Therefore, a nitrate test in water is crucial.

What do the Nitrate results mean?

Milligrams of nitrogen per liter (mg/L)

0 – 3.15: Typical Range (Unpolluted waters should be less than 4.0 mg/L)

0 – 3: Good range

3.1 – 5: Fair range

Greater than 5: Poor range
