Health Effects of Nitrite Exposure

Blue baby syndrome

Can block oxygen in blood of infants under 6 months

Methemoglobinemia

Converts hemoglobin, reducing blood oxygen-carrying capacity

Infants below 6 months can develop methemoglobinemia ('blue baby syndrome'). Combined nitrate+nitrite limit is 10 mg/L.

Frequently Asked Questions

Is there nitrite in Utah water?

Utah has 2,385 public water systems. 1885 have recorded nitrite violations based on EPA SDWIS data. If you are on a private well, your water is not covered by these regulations and should be tested independently.

How can I check my Utah water for nitrite?

Search for your water system using the WaterCheck system lookup, or contact your utility and request a copy of your Consumer Confidence Report (CCR). The CCR is published annually and lists all detected contaminants, their levels, and the EPA MCLs. For private wells, contact a state-certified lab for independent testing.

What is the EPA limit for nitrite?

The EPA Maximum Contaminant Level (MCL) for nitrite is 1 mg/L as N. Systems that exceed MCLs are required to notify customers and take corrective action.
