What Are Nitrates in Water?

Nitrates are a form of nitrogen that can enter groundwater from fertilizer runoff, septic systems, animal waste, and natural soil conditions. Because nitrates dissolve easily in water, they are commonly found in private wells and rural water sources.

High nitrate levels in drinking water can be a health concern, especially for infants, pregnant women, and livestock. The best way to know if nitrates are present is through professional water testing.
