Nitrates / Tannins

 

Nitrate (NO3) is a naturally occurring form of nitrogen (N) which is very mobile in water. It is essential for plant growth and is often added to soil to improve productivity. Water moving down through soil after rainfall or irrigation carries dissolved nitrate with it to ground water. It is also common from leakage or septic tanks. In this way, nitrate enters the water supplies of many homeowners who wells or springs. Drinking water high in nitrate is potentially harmful to human and animal health
