Blue baby syndrome

Frequently Asked Questions
Is there nitrite in Kentucky water?
Kentucky has 2,232 public water systems. 1183 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 Kentucky 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.
