HOUSEHOLD WATER GUIDE

Nitrate in well water

Nitrate can enter groundwater from fertilizers, septic systems, agriculture, and other sources. It is a routine private-well test and is especially important when infants may consume the water.

Why nitrate is different

Nitrate is a household-supply question for a private well. Utility reports from a nearby public system do not establish the nitrate level in a private well.

Who should pay extra attention

Infants are particularly sensitive to high nitrate exposure, so households using well water for infant formula should make nitrate testing a priority.

Find the local price first

County health programs can sometimes cost much less than private laboratory packages. The address plan checks local and published options before recommending a paid route.
